Simple pero completo regulador para cargar baterías de litio de 3,6v-3,7v cuya tensión a plena carga es de 4,2v. Bajo mi punto de vista solo un pequeño defecto y es que cortan la carga con 4,16v no llegando a los 4,2v, imagino que como medida de seguridad, aunque normalmente no les pasa nada si superan levemente los 4,2v.

These are as described. They use a 'mini' usb connector instead of the 'micro'. Good quality and they don't get hot.

When ordered 10 pcs arrived, some of the modules had a mini usb while the others had a micro usb sockets. I didn't expected such a mix of sockets but all in all it was not a big problem.

tested one and it works fine. It charged my 18650 batteries to 4.19 V. The max measured current is about 800 mA. One negative thing : the connection is mini USB not micro USB. Fortunatly I still have a mini USB cable. But if you don't have such a cable, buy another charging model. This is specified in the description but I haven't noticed it. It is my fault :( The modules I received are different from the one presented in the photos of banggood. For those who wonder if they can use several modules to charge several batteries mounted in series (ex 4S mount), it is not possible because the negative input is shortcutted with the negative output. I verified it myself. So mouting them in series will create a shortcut. Either a module or a battery will explose !!!

They work perfectly and are really cheap! I used them for a DIY 18650 charger and haven't had any problems so far!

They work perfectly for 1s applications but short out if you try to use more than one in any configuration to charge any configuration of batteries. This is no fault of the product, I just had a few extra and got curious enough to sacrifice a few.

Carga bien, se pone bastante caliente con lo cual un disipador no le vendria nada mal. Algunos vinieron con mini usb y otros con nano.... 10 dias en llegar a españa con envio normal. RECOMENDABLE!!

It cannot get much better than this. These are 10 tp4056 based li-ion battery charging modules. I used them to charge 10 18650 cells at a time from a 5V rail. The SMD resistor can be changed if you prefer a different charge current (search for the TP4056 datasheet online). It is slightly difficult to mount, though you can drill a mount hole into the ground plane - there is ample room for this.
