Review on πŸ”‹ Daier 5Pcs USB 18650 Battery Charger Module 2A Boost, Converts 3.7V to 5V 9V 12V, for Lithium Li-ion Batteries by Karla Richter

Revainrating 5 out of 5

Requires modification

Cannot be used in dual mode if you turn on the device and charge the battery at the same time. The load cycle never completes because the load shuts down the controller. (This can also charge the battery). However, they can be modified with a cut and two Schottky diodes and work like a champ. It would also be nice if the "Load" and "Ready" pins were available so they could be controlled with an external device.

Pros
  • Best in class
Cons
  • Only available in black
