Lsgoodcare 5V DIY Phone Heatsink Module Kit, USB Semiconductor Refrigeration Cooler, Tablet Cooling System Peltier Heat Sink with Heat conducting Sheet

It takes a while to cool, but it reaches the temperature.

A+

This is a really good product. I really like it. It gets very cold very quickly and it produces frost really fast.

Nifty little gadget but its just that. Not really applicable to many use cases, cant really scale with them given the price but a good proof of concept for sure

Does a great job of cooling, but the pad is much smaller than I expected. I guess I should have read the description a little better before buying.

The media could not be loaded. This little Peltier cooler sure gets cold. This a pre assembled cooler that also has a barrel connector inline meaning you can add a switch to it. Debating on using this to help keep beverages cool or my phone. I have used this kind of cooler with my phone and seen huge differences in temperature when taking photos outside . This is a part for a project and for the most part is well designed (alignment issue for me with the fan being not square on the radiator)The future is a dish best served cold hehe. So know add this to a small water pump some coper tubing and have a home made Ac fan. Lots of options for this.

For a device that runs off 5v USB, the cold side gets cold super fast. Not too cold to freeze things, but cold enough that you can't hold it on your skin for long. The hot side gets warm and stays that way. The fan doesn't seem to move much air. There is a sticky thermal pad but not much else for mounting. Neat device, now I need a project to use it in.

It broke, plate just fell apart and broke in a possible record time of less than 2 weeks.
