Customers are mixed about the heat of the transformer. Some mention that it's thermally efficient, easy to work with, and doesn't overheat. The board is running cool, and the chip does not get hot while charging. However, others say that the circuit gets hot very quickly and then fails shortly after, even with heat sinks.

"...The board is running cool, I don't think a heatsink is needed (I saw a review about needing a heatsink?)...." Read more

So far sooo good, Note the I bought the USB STEP DOWN model and it works great. I only needed one but four for the price is a steal. They feel sturdy and have good pads I was able to solder an XT60 to one pad a thick jumper wire to the other. I'm pretty sure the three amps are split when using it with two devices so 1.5 amps per USB port. I've tested it so far running at varying voltages from 11.1 3S (Li-ion), 12-14V (lead acid), 18V drill battery lol and it worked with all. As a precaution I would advise anyone using this module to at least add an inline fuse and build a case to prevent any possible shorts and keep sensitive electronics safe. Added heatsinks to the IC's on three, unsure if that's the most suitable location but it will do. So far I've powered a Pi Zero and ESP8266 boards and even made a small solar charging station. If you plan on using these for a solar charger I would recommend using a battery as well as these don't have the smoothing capacitors or regulators to make the best of the power variations from a direct connection to a solar panel. Don't get me wrong I hooked one up to a 50 watt panel and there was some minor wine coming from the board, but I pushed it and it did charge a power bank but after an hour and noticeable heat on the heatsink and I decided to unplug it, and it still works

5.0 out of 5 stars Charges fast
Reviewed in the United States on July 28, 2020
I know it's not a fast charger but, these chips charge decently fast. I made my own battery backup box using some cells I bought a long time ago. The chip does not get hot while charging, letting me know that build quality is excellent. It's very power efficient too. I charged a Xiaomi Mi Max 3, and a Samsung Galaxy S8, and still had available energy.

I'm very happy with my purchase.
