Excellent for building a portable project with a single LiPoly, and recharge it from microUSB!
Most portable projects are now using LiPoly battery technology, but it requires a more finicky method of charging. This TP4056-based module makes it trivial to add a dedicated single-cell charger to your project, powered by any microUSB power source.

Specifications:
Note: In default configuration, this charger will pull as much as 3.7W from a USB port, which are nominally rated 2.5W on a standard PC. Make sure you use a USB charger or powered USB hub.
Cells are becoming very tolerant of high-current charging, but for the best battery life, use the 1/3 rule of thumb. A 1000mAh cell is best treated by charging at approximately 300mA. If desired, adjust the maximum charge rate of your module by replacing the small SMD resistor "R1" with a value listed below:
R1(K) I(mA)
30 50
20 70
10 130
5 250
4 300
3 400
2 580
1.66 690
1.5 780
1.33 900
