Q. Is PiggyPower just a Peltier?
A. NO! This is the most common misconception we get. PiggyPower is not a cheap cooling chip flipped upside down and sold as a generator. PiggyPower is a purpose built thermoelectric power cell designed to turn heat into usable electricity. Cheap Peltier projects WILL fail because they are not built for serious heat, proper clamping, stable cooling, long term durability, or real electrical output. PiggyPower is built as a complete system with heat spreading, water cooling, compression, wiring, output electronics, and real world testing.
Q. Why is PiggyPower so expensive?
A. Because you are buying a finished, ready to go out of the box, assembled, water cooled, tested power cell, not a loose science project part. The cost comes from the custom generator technology, aluminum heat spreaders, water block cooling, hardware, wiring, electronics, labor, testing, and quality control. Cheap online parts may look similar to people who do not understand the system, but they are not the same product and they are not built for the same level of output or longevity. Compared to other companies, we are actually cheaper!
Q. Can I buy the same thing cheaper online?
A. No. You can buy cheap parts online, but that does not make them the same thing. Most cheap thermoelectric products are low output novelty devices that might light a tiny LED under perfect conditions. PiggyPower is custom designed to produce useful power from real heat sources and run real loads like USB devices, lights, battery banks, routers, and emergency electronics.
Q. What makes PiggyPower better than the cheap competitors?
A. PiggyPower is built around usable power, strong thermal design, and long term durability. A lot of cheap units are built around looking good in a short demo. PiggyPower is built with proper heat transfer, water cooling, strong compression, quality wiring, tested electronics, and practical output. The goal is not to make a meter blink. The goal is to make power you can actually use.
Q. Does PiggyPower create free energy?
A. No. PiggyPower converts heat into electricity. It needs a heat source and a cooler side. The value is that heat is already everywhere. Fire, charcoal, propane, wood stoves, camp stoves, gas burners, hot surfaces, and waste heat all contain energy that usually gets thrown away. PiggyPower captures part of that heat as electricity.
Q. How does PiggyPower work?
A. PiggyPower works from a temperature difference. One side gets hot and the other side is kept cooler, usually with water cooling. That temperature difference creates electrical output. More stable heat and better cooling generally means better performance.
Q. Why does it need water cooling?
A. Cooling is half the system. If the cold side gets hot, output drops. Water is very good at carrying heat away, which helps maintain the temperature difference needed to produce useful power. That is why PiggyPower uses water cooling instead of relying on tiny fans and weak heat sinks.
Q. Does the water get hot?
A. Yes. The water is removing heat from the cold side, so it will warm up over time. That heat can still be useful. In a full heat recovery setup, the same heat that helps produce electricity can also contribute to hot water or space heating.
Q. Will it power my whole house?
A. No. PiggyPower is not sold as a whole house power plant. It is made for emergency power, off grid support, battery charging, lighting, communications, and waste heat recovery. Think phones, battery banks, LED lights, routers, radios, small USB devices, and emergency electronics.
Q. How much power does it make?
A. Output depends on the model, heat source, cold side temperature, water flow, and load. PiggyPower cells are sold by output class, such as 20 W, 40 W, 125 W, and 250 W. The rating means the cell is built for that class of output under proper thermal conditions. A weak flame, hot water on both sides, or poor cooling will reduce output.
Q. Why does the output change?
A. Because heat conditions change. If the hot side cools down, output drops. If the cooling water warms up, output drops. If the load is too large, voltage can sag. PiggyPower is real world hardware, so performance follows the actual heat and cooling conditions.
Q. Can I use it with charcoal?
A. Yes. Charcoal is one of the best simple heat sources because it is compact, hot, affordable, and easy to store. It is great for demonstrations and emergency use when handled safely outdoors or in proper ventilation.
Q. Can I use it with propane?
A. Yes. Propane is a very practical heat source for PiggyPower because it is controllable, easy to store, and already common for camping, emergencies, and off grid use.
Q. Can I use it with a wood stove?
A. Yes. A wood stove is one of the most natural use cases because the heat is already being produced. PiggyPower can recover some of that heat as electricity while the stove continues doing its normal job.
Q. Why not just get a solar panel?
A. Solar panels are great when you have sun, space, good weather, and enough time to charge. PiggyPower solves a different problem. It makes power from heat, which means it can work at night, during storms, in winter, around camp, during outages, and anywhere a usable heat source is available. Solar depends on sunlight. PiggyPower depends on heat and cooling.
Q. Is PiggyPower supposed to replace solar?
A. No. PiggyPower and solar can actually work well together. Solar is strongest during good daylight. PiggyPower is strongest when heat is available. For emergency use, having more than one way to make power is a major advantage.
Q. Is PiggyPower more practical than solar?
A. In some situations, yes. A solar panel needs sunlight and surface area. PiggyPower needs heat and cooling water. For emergency use, bad weather, nighttime use, camping, winter outages, or waste heat recovery, PiggyPower can be more useful than people expect.
Q. Why compare PiggyPower to solar at all?
A. People compare them because both can make off grid electricity. The difference is when and how they work. Solar uses light. PiggyPower uses heat. Solar is strongest in good sun. PiggyPower can work after dark when heat is available.
Q. Is PiggyPower better than solar during an outage?
A. It depends on the outage conditions. If it is sunny and you have panels set up, solar is great. If it is nighttime, storming, snowing, cloudy, or you already have heat available, PiggyPower can be very useful.
Q. Is PiggyPower efficient?
A. Pure electrical efficiency is only part of the story. PiggyPower is about heat recovery and combined heat and power. The electricity is useful, but the remaining heat can still be used for cooking, warming water, or heating a space depending on the setup. Judging it like a normal generator misses the bigger point.
Q. Is PiggyPower inefficient?
A. If you only look at electricity, thermoelectric generation is not the highest efficiency way to make power. But PiggyPower is not only about electrical efficiency. It is about recovering useful electricity from heat that may already be available, already being used, or otherwise wasted. In a combined heat and power setup, the leftover heat still has value. So it actually can make a system MORE efficient.
Q. Why would anyone use this if thermoelectrics are low efficiency?
A. Because efficiency is not the only thing that matters. Reliability, silence, no engine, no internal moving power producing parts, fuel flexibility, heat recovery, and emergency usefulness all matter. A device can be lower in pure electrical efficiency and still be very useful in the right application. If we take a wood stove for example, the heat is going up the flue and getting wasted. PiggyPower is able to extract a portion of that wasted heat, and turns that wood stove into a dual usage device, so it actually becomes MORE efficient.
Q. Does PiggyPower waste the heat?
A. No. The electricity comes from a portion of the heat flow. The rest of the heat can still be used depending on the setup. That is why PiggyPower makes the most sense around heat sources where the heat already has a purpose, such as cooking, warmth, hot water, camping, or emergency heating.
Q. What does combined heat and power mean?
A. Combined heat and power means electricity and usable heat are produced from the same heat source. Instead of wasting the heat after electricity is made, the heat can still be useful. That is where PiggyPower becomes very interesting for off grid, emergency, and heat recovery applications.
Q. How is this different from a normal generator?
A. A normal generator uses a fuel powered engine with moving parts, noise, exhaust, oil, maintenance, and mechanical wear. PiggyPower uses solid state thermoelectric generation from heat. It is for smaller loads, emergency electronics, battery charging, lights, and heat recovery, not replacing a large gas generator for heavy household loads.
Q. Why not just use a gas generator?
A. Gas generators are useful, but they are loud, mechanical, fuel hungry, maintenance heavy, and often waste a lot of heat. PiggyPower is solid state, quiet, compact, and built for smaller emergency loads and heat recovery. It fills a different role.
Q. Why would I need this if I already have batteries?
A. Batteries store energy. PiggyPower produces energy from heat. A battery is great until it is empty. PiggyPower can help recharge batteries when fuel, fire, or waste heat is available.
Q. Can it make power after dark?
A. Yes. PiggyPower does not need sunlight. It needs heat and cooling. That makes it useful at night, in storms, during winter, and in situations where solar is not producing.
Q. Can it charge a phone?
A. Yes, with the proper output electronics. PiggyPower can charge phones, USB battery banks, and other small electronics depending on the model and heat conditions.
Q. Can it run lights?
A. Yes. LED lighting is one of the best uses for PiggyPower because LEDs are efficient and useful in an outage. A properly heated PiggyPower cell can run LED strips, USB lights, and other small lighting loads.
Q. Can it run a Wi-Fi router?
A. Yes, depending on the router and model being used. Many small routers are within the practical range of PiggyPower, especially with a battery bank or proper voltage regulation in the system.
Q. Can it charge a power bank?
A. Yes. Charging a battery bank is one of the cleanest use cases because the battery smooths out the power and stores the energy for later use.
Q. Can it run a refrigerator?
A. If you stored all of your generated electricity in a battery, then connected that to a suitable inverter, then yes it can do that. The length of runtime would be dependent on your cell size, charge time, and so on.
Q. Can it run a heater?
A. Electric heaters use a lot of power, so PiggyPower is not meant to run an electric space heate directly. As stated above, you would be better off storing your generated power in a battery, then later using it for your desired use cases. Another approach is to use the original heat source for warmth and use PiggyPower to recover a portion of that heat as electricity.
Q. Does it boil water?
A. PiggyPower itself does not boil water. The heat source may be able to boil water, and PiggyPower can recover some electricity from that heat flow. The cell is part of a heat recovery system, not the flame or burner itself.
Q. Can it charge a car battery?
A. With the correct electronics and enough power, it can contribute charge to 12 V batteries, but expectations need to match the model. A small cell is not going to rapidly charge a large dead battery. Battery charging depends on voltage regulation, current, battery size, and runtime.
Q. Can it run 120 V AC appliances?
A. Only if paired with the proper inverter and enough power. Small AC loads are possible with the right setup, but PiggyPower is usually strongest with DC loads like USB devices, LED lighting, battery banks, routers, and small electronics. You could take your produced power, store it in a battery, and later use it with an inverter for your 120v loads however.
Q. Is it silent?
A. Yes it is basically silent. The power producing part is solid state and has no engine, piston, crankshaft, or combustion chamber inside it. Any sound would come from external items like a water pump, fan, burner, or fuel source.
Q. Does it have moving parts?
A. The cell itself has no moving power producing parts. A full setup may use a pump or other accessories, but the electrical generation happens through solid state thermoelectric technology.
Q. How long does it last?
A. If you take care of it, you should get many years out of it. Longevity depends on proper use, temperature control, cooling, and avoiding abuse. PiggyPower is built for durability with strong thermal contact, controlled compression, water cooling, and proper materials. It is designed to outlast cheap novelty units that are usually pushed too hard with poor cooling and poor construction.
Q. What can damage it?
A. The biggest risks are overheating, poor cooling, extreme thermal shock, physical abuse, incorrect wiring, or using it outside its intended operating range. Like any serious power device, it needs to be used correctly.
Q. Can I run it dry without water?
A. No. The water cooled models are designed to be cooled. Running without proper cooling can reduce output and may damage the system. Heat input and cooling need to work together.
Q. Can I use dirty water, lake water, or a bucket?
A. Yes, and a bucket can work for short use, but the water will warm up. Larger water sources last longer. Cleaner water is better for long term use because it helps avoid clogging, buildup, and pump issues.
Q. Why does the cold side matter so much?
A. The cell does not only care about heat. It cares about the difference between hot and cold. If both sides become hot, the temperature difference shrinks and power drops. Good cooling keeps the system productive.
Q. Why does PiggyPower use water instead of a giant heat sink?
A. Water carries heat away much better than a small passive heat sink. A giant heat sink can help, but it gets bulky fast. Water cooling allows stronger cooling in a compact setup and helps maintain the temperature difference needed for useful output.
Q. Can I use snow or ice water?
A. Yes. Colder water can improve performance a LOT because it helps keep the cold side cooler. Cold outdoor conditions can be a real advantage for thermoelectric generation.
Q. Does it need a pump?
A. Many practical setups use a small pump to circulate cooling water. The pump helps move heat away from the cold side and keeps performance more stable. Some setups may use gravity flow or other methods, but a pump is usually the cleanest solution.
Q. Doesn’t the pump use power too?
A. Yes, but small pumps can use very little power compared with the output of a properly heated cell. In a practical setup, the system can charge a battery while that battery also supports the pump, making it self sustaining as long as you have heat and cooling.
Q. Can PiggyPower be self sustaining?
A. In the practical sense, yes, when the cell produces enough power to support the small cooling pump while also charging a battery or running useful loads. It still needs heat and cooling. It is not free energy.
Q. What fuel works best?
A. Charcoal, propane, wood, and other steady heat sources are all practical. The best fuel depends on the situation. Propane is controllable. Charcoal stores well and burns hot. Wood works well when a stove or campfire is already being used.
Q. How much fuel does it use?
A. Fuel use depends on the heat source, model, output target, and runtime. PiggyPower does not create the heat source. It captures a portion of available heat as electricity. The more useful question is whether that heat was already being produced or already useful for something else. To give you an example though, a typical barbecue tank would get you around 30-40 hours of runtime on the 125w unit.
Q. Can I use candles?
A. Candles can demonstrate the concept, but they are very limited heat sources. A candle may produce enough for small experimental output, but serious power requires a stronger and more controlled heat source.
Q. Can I use Sterno?
A. Sterno can work for small demonstrations and compact emergency setups, but output depends on the size and strength of the flame, the model used, and the cooling side. It should not be expected to perform like charcoal, propane, or a wood stove.
Q. Can I use a camp stove?
A. Yes. Camp stoves are one of the more practical heat sources because they are portable, controllable, and already common for outdoor and emergency use.
Q. Can I use waste heat from another machine?
A. Yes, if the heat source is hot enough, accessible, and safe to interface with. PiggyPower is especially interesting where heat is already being wasted.
Q. Why does the rating say “up to”?
A. Because output depends on the temperature difference and the load. “Up to” is the honest way to rate heat powered equipment. The same cell can produce different output depending on hot side temperature, cooling water temperature, water flow, and electrical load.
Q. Why did I see a lower number than the rated output?
A. The usual reasons are not enough heat, cooling water getting too warm, poor contact with the heat source, an undersized flame, or a load that is not matched properly. Thermoelectric output follows the actual thermal conditions.
Q. Why does PiggyPower cost more than a solar panel with the same watt rating?
A. Solar panels are mass produced at huge scale and only need sunlight to hit a flat surface. PiggyPower is a finished thermal power cell with custom generator technology, aluminum heat spreading, water cooling, compression hardware, wiring, electronics, assembly, and testing. It is a different product category.
Q. Can PiggyPower work indoors?
A. The cell can operate wherever the heat source and cooling setup are safe. A gas stove during an outage could be used for example. The bigger issue is the heat source. Combustion sources like charcoal and propane require proper ventilation and safe handling. Indoor use depends on the specific heat source and setup.
Q. Can it be used with a gas stove during an outage?
A. A gas stove can provide the heat, but safe use depends on the appliance, ventilation, and setup. PiggyPower is designed to recover heat as electricity, but the heat source must be used safely and responsibly.
Q. Can I leave it running unattended?
A. No heat powered setup should be treated casually. PiggyPower should be monitored like any device using heat, fuel, hot surfaces, pumps, and electrical loads. Safety should always be your first priority, no questions asked.
Q. Is the output clean enough for electronics?
A. Yes, PiggyPower should be used with the proper output electronics for the device being powered (included with your unit). The cell produces raw electrical output based on heat conditions, and electronics help regulate that power for USB charging, battery banks, lights, and other loads.
Q. Why not connect directly to my phone?
A. Phones expect stable regulated power. The better setup is to use the included proper electronics and often charge a battery bank first. The battery bank smooths out changing output and gives the phone a more normal charging source.
Q. Is a battery bank recommended?
A. Yes. A battery bank is one of the best accessories because it stores the energy and smooths out changes in heat input. PiggyPower makes power from heat, and the battery bank lets you use that power more conveniently. The battery bank can be recharged on the same system, making it essentially self sustaining as long as you have heat and water.
Q. Does PiggyPower need perfect conditions?
A. No, but better conditions produce better results. Stronger heat, colder water, good water flow, and proper load matching will always perform better than weak heat and warm cooling water.
Q. What happens if the water gets too warm?
A. Output drops because the temperature difference gets smaller. The cell needs one side hot and the other side cooler. Warm cooling water reduces that difference.
Q. Can I just use tap water?
A. Yes, tap water can be used in many setups. For longer operation, the water source, flow rate, and temperature matter. A small amount of water will heat up faster than a larger reservoir.
Q. Can I use a lake, stream, or large bucket?
A. Yes. Larger water sources are useful because they can absorb more heat before warming up. A lake, stream, large bucket, tank, or radiator setup can all help maintain cooling longer.
Q. Is PiggyPower waterproof?
A. The system uses water cooling, but that does not mean the electronics or accessories should be soaked. Water should stay where it belongs, inside the cooling path or reservoir, and electrical connections should be protected whenever possible. That said, these cells are more rugged than people might expect. We have used them in the rain and even tested fully submerging them to see whether they would still function afterward, and they did. However, PiggyPower does not advertise these cells as waterproof because we do not want to create the wrong expectation or encourage careless use. Getting wet does not automatically mean the cell is destroyed, but submersion, rain exposure, or wet electrical connections should not be treated as a normal use case. Use good judgment and keep the electrical side protected.
Q. Why does the product look heavy duty?
A. Because it is! These aren't toys, PiggyPower devices need real thermal mass, pressure, and heat transfer. Thin, flimsy builds do not handle serious thermal cycling well. PiggyPower is built to be a real device, not a fragile novelty item.
Q. Why aluminum plates?
A. Aluminum spreads heat well, keeps the system compact, and helps transfer heat evenly across the cell. Even heat distribution is important for performance and durability.
Q. Why not make it tiny?
A. For their size, they are already very compact for their power outputs. Power requires heat flow. A tiny device can only move and convert so much heat. PiggyPower is compact for what it does, but useful output requires real surface area, cooling, and thermal mass.
Q. Why are cheap thermoelectric generators so weak?
A. Most cheap units are built with small parts, weak cooling, poor heat transfer, and low cost materials. They may work for a small LED, but that does not mean they are built for useful emergency power.
Q. Why do people online say thermoelectrics are useless?
A. Because many people have only seen cheap Peltier experiments or weak novelty products. Poor examples make the whole category look bad. PiggyPower is built around practical use, not tiny lab tricks.
Q. Is PiggyPower a science experiment?
A. Not at all. While PiggyPower is based on real thermoelectric science, the finished cells are built as practical power devices. The goal is not just proving the effect exists. The goal is making useful electricity from heat.
Q. Is this new technology?
A. Thermoelectric generation itself is not new. PiggyPower’s value is in the finished product design, packaging, cooling, usability, and practical heat recovery approach.
Q. Why has nobody made this common already?
A. Thermoelectric systems are easy to demonstrate badly and hard to build well. Useful output requires strong thermal design, cooling, compression, electronics, and realistic expectations. PiggyPower focuses on making the concept practical.
Q. Can PiggyPower run forever?
A. While these are built to last many years under normal usage, no physical product runs forever. Longevity depends on proper use, cooling, heat control, and avoiding abuse. PiggyPower is built for durability, but it should still be treated like serious heat powered equipment.
Q. What maintenance does it need?
A. Not much, arguably zero compared to other generation methods. Basic care means keeping the cooling path clean, protecting the electronics, checking connections, avoiding overheating, and using the device within its intended range. You should keep the bottom plate clean as well, don't let it get all covered in soot etc.
Q. Is PiggyPower safe indoors?
A. PiggyPower itself is not the same thing as the flame or fuel source. The safety concern depends on the heat source being used. Charcoal, propane, open flame, and combustion appliances require proper ventilation and safe handling. The cell can be used in many setups, but the heat source must always be treated seriously.
Q. Can I use it during a power outage?
A. Yes. That is one of the main use cases. During an outage, PiggyPower can help charge battery banks, run lights, power small electronics, and support communication devices when heat and cooling water are available.
Q. Is PiggyPower good for emergencies?
A. Yes. PiggyPower is especially useful when grid power is down and small electronics matter. Lights, phones, radios, routers, USB devices, and battery banks can be extremely important during an outage.
Q. Is PiggyPower good for off grid living?
A. Yes, especially as part of a broader energy setup. It pairs well with batteries, solar, heat sources, wood stoves, propane systems, and other off grid equipment.
Q. Is PiggyPower good for camping?
A. Yes. Camping naturally involves heat sources, outdoor ventilation, and access to water. That makes camping one of the most practical environments for PiggyPower.
Q. Is PiggyPower good for homesteads?
A. Yes. Homesteads often already use wood, propane, hot water, outdoor cooking, or heat producing systems. PiggyPower can recover some of that heat as useful electricity.
Q. Can PiggyPower be used in winter?
A. Yes. Winter can actually help because colder cooling water improves the temperature difference. Heat is also more likely to be available in winter because people are already using stoves, fires, or heaters.
Q. Can PiggyPower be used in summer?
A. Yes, but cooling water may start warmer, so output may be lower than in colder conditions. The same principle still applies: stronger temperature difference means better output.
Q. Does PiggyPower work better in cold weather?
A. Often, yes. Cold water and cold outdoor temperatures can improve cooling. That can increase the temperature difference and improve output.
Q. Can I use PiggyPower with boiling water on the hot side?
A. Hot water can provide heat, but boiling water is not as hot as many flame or stove surfaces. Output depends on the temperature difference. A hotter heat source usually gives better results, as long as the system is used safely. Boiling water would land you around half the rated output.
Q. Can PiggyPower run medical devices?
A. PiggyPower can help charge batteries or support small electronics, but critical medical equipment should always have approved backup power. Do not rely on PiggyPower as your only source for life critical devices. If you choose to use it for this, please at least have a backup method just in case.
Q. Can PiggyPower power communication devices?
A. Yes. Communication is one of the best use cases. Phones, radios, routers, hotspots, and battery banks can be supported depending on the model and setup.
Q. Is PiggyPower portable?
A. Yes, but it is practical portable, not pocket portable. PiggyPower is compact for the power it can produce, especially compared with some solar setups that need larger surface area and good sun exposure. You still need a heat source, cooling water, and the correct accessories.
Q. Is this for preppers?
A. Yes, but not only preppers. It is also useful for campers, off grid users, experimenters, homesteaders, emergency kits, remote work areas, and anyone interested in heat recovery.
Q. Is PiggyPower made in America?
A. PiggyPower cells are designed, assembled, and tested in America. The goal is to provide a serious finished product with domestic assembly, testing, and quality control instead of selling random untested parts.
Q. Do I need technical knowledge to use it?
A. Basic understanding helps, but the finished cells are designed to be ready to go out of the box. The manual included will help you with any questions you have, or we are always here for support. PiggyPower provides the core system so you do not have to figure out clamping, cooling, wiring, and electronics from scratch.
Q. Why does PiggyPower focus so much on real demos?
A. Because real loads matter. A voltage reading by itself does not prove much. PiggyPower demos focus on charging battery banks, running lights, powering USB devices, and showing actual usable output.
Q. Are the demos real?
A. Yes. PiggyPower demos are meant to show actual loads being powered, such as lights, battery banks, USB devices, routers, and charging accessories. Real loads matter more than a voltage number on a meter.
Q. Why should I trust PiggyPower’s ratings?
A. PiggyPower ratings are tied to real thermal conditions and real loads. Heat powered output always depends on the setup, so PiggyPower focuses on practical demonstrations instead of fake perfect world claims.
Q. Why do some people misunderstand PiggyPower?
A. Most people are used to thinking in terms of batteries, solar panels, and gas generators. Heat to electricity devices are less familiar, so people often judge PiggyPower as if it were trying to be one of those things. PiggyPower is its own category: solid state heat recovery for practical small power.
Q. What is the simplest way to understand PiggyPower?
A. PiggyPower turns heat into usable electricity. Give it heat on one side, keep the other side cooler with water, and it can produce power for small electronics, batteries, lights, and emergency devices.
Q. What problem does PiggyPower solve?
A. PiggyPower helps solve the problem of small emergency power when heat is available but grid power is not. It also helps recover electricity from heat that would otherwise be wasted.
Q. What is the main advantage of PiggyPower?
A. It makes useful electricity from heat without an internal engine. That gives you quiet, solid state, fuel flexible power for small loads and emergency use.
Q. What is the main limitation of PiggyPower?
A. It needs heat and cooling. Without a strong temperature difference, output will be low. PiggyPower is powerful for its category, but it still follows real thermal physics.
Q. What should I buy first?
A. Choose based on the load you want to power. Smaller cells are better for lights, USB devices, and battery banks. Larger cells are better when you want more headroom, faster charging, or larger small electronics loads.
Q. Who should buy PiggyPower?
A. PiggyPower is for people who understand the value of reliable small power when normal power is unavailable. It is for emergency preparedness, off grid living, camping, heat recovery projects, and people who want something more serious than a toy thermoelectric generator.
Q. Who should not buy PiggyPower?
A. Do not buy PiggyPower expecting it to replace the electrical grid, run your entire house, or magically create power with no heat source. It is a serious heat to electricity device, not a miracle box.
Q. What am I actually paying for?
A. You are paying for a finished power cell that has already solved the annoying parts: thermal contact, cooling, compression, wiring, output control, assembly, and testing. You are paying for a device designed to make thermoelectric power practical instead of frustrating.
Q. Is PiggyPower worth it?
A. If you want a serious emergency, off grid, heat recovery power device that can work when solar or other means is weak or unavailable, PiggyPower makes a lot of sense.
Q. Why does PiggyPower matter?
A. Because heat is one of the most common wasted energy sources on earth. PiggyPower gives people a way to recover some of that heat as electricity in a compact, solid state system. For outages, off grid use, camping, and emergency power, that is a very real advantage.
