The PiggyPower Cell 125 is a water-cooled thermoelectric generator designed to demonstrate the Seebeck effect and the direct conversion of heat into electrical power. It is intended for hands-on experimentation, off-grid projects, and educational environments where higher, continuous power generation is desired.
Each PiggyPower unit is built to order. Minor cosmetic differences may exist between units, but all performance and functionality remain the same.
LONGEVITY & RELIABILITY
This is a solid-state thermoelectric generator with no moving parts, no bearings, no combustion, and no mechanical wear surfaces. Under proper thermal management, thermoelectric modules are known to operate for many tens of thousands of hours. Unlike solar inverters, wind turbines, or fuel-based generators, there are no engines to seize, no gearboxes to wear, and no routine maintenance cycles.
This system is designed to be a long-term power asset, not a disposable consumer product.
WHAT THE PIGGYPOWER CELL 125 DOES
When supplied with a controlled heat source and adequate cooling, the PiggyPower Cell 125 can generate up to 125 watts of electrical power. At optimal operating conditions, this corresponds to approximately 29 V at 4.2 A at a maximum temperature differential of about 190°C with active water cooling. Actual output depends on the temperature difference between the hot side and cold side of the unit, as well as the effectiveness of the cooling setup.
This system produces electricity continuously as long as heat and cooling are maintained. There are no moving parts inside the generator itself.
COMPLETE, READY-TO-RUN KIT
Every PiggyPower Cell 125 is sold as a complete system, not a bare module. Each kit includes everything required to operate the generator out of the box.
What’s included:
- One fully assembled PiggyPower Cell 125 generator block
- Integrated cold-side water cooling block
- Water pump for active cooling
- Cooling hoses and fittings
- Power conditioning module for delivering usable electrical output
- Pre-wired electrical leads
- Basic operating instructions and educational overview
You only need to provide a heat source and water. No additional electronics, controllers, or fabrication are required.
(Stove, fire source, fuel, and water container are not included.)
HEAT SOURCE COMPATIBILITY
The PiggyPower Cell 125 is designed to operate with a wide range of controlled heat sources, including propane stoves with adjustable output, wood stoves with moderated surface temperature, enclosed fire platforms, and any heat source that can be reliably kept within safe operating limits.
The generator must always be placed on a solid intermediary surface such as a metal plate or skillet. Direct flame contact with the generator block is not permitted.
COOLING REQUIREMENTS
Active water cooling is required for proper operation. The included pump circulates water through the cold-side block to maintain a temperature differential. Cooling water may be supplied from a bucket or container, a stream, pond, or other body of water, or open-loop or closed-loop circulation systems. Improved cooling directly increases electrical output.
INTENDED USE
This kit is intended for learning and experimentation with thermoelectric generators, off-grid projects requiring sustained output, demonstrations of heat-to-electric conversion, STEM education and technical training, and continuous power generation experiments.
FINAL DISCLAIMER AND SAFETY INFORMATION
The PiggyPower Cell 125 is an educational and experimental device, not a certified consumer power appliance. Maximum hot-side temperature is 200°C and must not be exceeded at any time. Exceeding 200°C will permanently damage the thermoelectric modules.
The user is fully responsible for temperature monitoring, fire safety, water circulation, electrical handling, and overall safe operation. A digital thermometer or thermal probe is strongly recommended.
This kit is not intended for use as a primary power source, automotive electrical systems, bulk battery charging, emergency medical power, life-support equipment, or any mission-critical system. All generated electricity must be regulated, stored, or used responsibly.
Each unit is tested prior to shipment, and operational video documentation is retained. Due to the nature of thermoelectric systems and custom assembly, no refunds or replacements are offered. Signature delivery is required.
BUILD AND SHIPPING INFORMATION
PiggyPower units are built to order in small batches. Please allow up to 30 days for assembly and shipment.
