    It works alright, though there's some issues with the 5v supply. there are 3x 5v supply pins, out of which one gives around 2.8v , and one fluctuates between 1 to 4.7v . all the 3v supply pins give around 3.3v the switch only works for usb in conclusion, it's still a better choice compared to other modules, as it is compact and works somewhat for the price.

    Good, took two, both workers. After sending it was necessary to activate- power on charge, micro USB, then began to give in load- 3.3 v., 5 v. and USB output. The switch on the USB output is weak, it's better to short it.

    3 Pieces, Packaged well. All Works unexpected. (DOA) Do not charge (attaching to charges - charger goes to ovearload protection mod - switches off) it' s due to chortened chargeing circuit (~ 0,09 Omh between (+) and (-) pins on micro USB Do not converts properly: * Must 3V , Actually 1,264 V; * Must 5V, actually 1.186V

    I couldn't use it. The 18650 battery on hand has protection circuitry and is approximately 69mm long. The terminal of this product was also a leaf spring on the negative side, so no battery was put in. I wanted an explanation that "the long 18650 can't be used." Like the battery box in the photo, the negative side can be used with coil-shaped terminals.

    Очень хорошее и нужное устройство для автономного питания ESP32 и Arduino. Кроме того плата имеет функцию зарядки. Для этой цены просто подарок!

    Good, does its job. Note: The additional output of 5V and 3V work well but they are always ON. The ON/OFF swtich is not applicable to those only works for USB out. Packaging: The charging pin holder was slightly pressed due to transit as it comes in a soft package. But nothing that could not be taken care of.
