## Description

Our goal is to meet your needs. Please feel free to let us know if there is any problem. It's honored to make you satisfied. - Model number: TES1-12704 - Voltage: 12V - Couples: 127 - Umax (V): 15.2- Imax (A): 4- ΔTmax(℃)≥66 - QM(W):36.5 WIncorporate both semiconductor technologies and electronic assembly techniques.Do not connect the cell to a power supply for more than a few seconds without a heat-sink on the hot side otherwise there will be internal overheating and destruction of the Peltier cell.

Review: Ecofan - We had an eco fan that accidentally got knocked over and ruined the original power cell. After we’d replaced I found this power cell and decided to give it a shot. After wiring it up the old fan started working again and it even seems to work better than the newer fan
Review: Reliable TEC Replacement – Still Going Strong After a Year - I’ve been using this thermoelectric module for over a year now, and it’s still performing flawlessly. It was a direct replacement for a failed module in a small thermoelectric cooling device, and it brought it back to full working order. Installation was straightforward if you're comfortable with basic soldering. Just make sure to apply fresh thermal paste—reusing the old paste isn’t recommended and can reduce cooling performance. A clean surface and proper paste application make a big difference in efficiency. This unit has held up well under regular use, and the cooling performance has remained consistent. For the price, it’s a solid and reliable option. Pros: Long-term reliability—still working after a year Easy installation for anyone with soldering experience Good performance in small thermoelectric cooling applications Affordable and effective replacement part Tips: Use new thermal paste for best cooling results Double-check polarity before soldering to avoid damage Cons: Not beginner-friendly unless you’ve soldered components before If you’re repairing a small thermoelectric cooling unit, this is a dependable replacement that delivers great value and performance.

## Questions & Answers

**Q: What do you what do use to connect the motor to the generator pad**
A: This Peltier device only requires electricity.  For my unit its 9V 2Amp DC.  There is typically a heat sink and fan used to dissipate the heat generated by the device.  It's a solid state cooling/heating device so the only "motors" involved are typically a motorized fan to assist with heat dissipation.  You can momentarily connect the device to power for a couple of seconds to ensure you identify the hot side from the cool side which you need to do to ensure you have the device positioned correctly.

**Q: how this is this?**
A: This device is a Peltier device, that basically replaces broken coolers and other devices that use Peltier devices for cooling purposes.  My small desktop fridge broke down and I was able to fix it by replacing this component.  I hope that answers your question.

**Q: Where do you get the Connectors**
A: These are soldered to the fan motor directly

**Q: Will this work in an ecofan?**
A: Working so far in 12 year old  Ecofan Original.  Very slightly smaller that the original. Side with printing  goes  up.

### ⭐⭐⭐⭐⭐ Back from the Dead!!
*by A***. on August 25, 2022*

My favorite mini-fridge broke down on me. It would no longer stay cool. It was just room temperature inside. The problem was that the peltier device (the white square device pictured) no longer functioned. These are inexpensive devices, but they only last around 5 years. As you can see from the date stamp that is what happened to my mini-fridge. Fortunately, I was able to remove the back of the mini-fridge and replace the the peltier device with this device I am writing the review on and it worked perfectly. It's pretty simple to replace and does require some wire splicing. As a test you can replace the device and then turn the unit on for 3 seconds and make sure the sides are set down correctly (there is a hot side and a cool side). The cool side is placed toward the fridge and hot side is the one that goes against the heat sink. Don't forget the thermal paste when replacing this component. All in all it was a 30 minute fix and my mini-fridge is back in working order. Thanks Amazon!!!
