Features: Current adjustable as long as you change the fixed resistors in the circuit board , then can change the output 100mA-1000mA, very convenient. Each module is tested before shipment and has high reliability. Uses high quality charging chip TP4056, the external circuit is simple, good protection performance and good high precision charging. Parameter: Charging method: Linear charging Current: 1A adjustable Charge precision: 1.5% Input voltage: 4.5V-5.5V Full charge voltage: 4.2V Led indicator: Red is charging / Blue is full charged Input interface: micro USB Work temperature: -10° ~ +85° Size: Small to 25X19X6 mm Package list: 10 pcs Lithium Battery Charging Board Module Note: - Ampere meter can only be connected to 5v input end of the module. - It is better that the charging current is 37% of the battery capacity. If you charge to the battery of 1000mAH, current of 400 is enough. - The charging connection wire should not be too thin or too long. This connection has a large resistance. If it is too thin, it will be more than the battery voltage. - Input reverse connection has no effect on the chip, but the output (battery end) will reverse the chip. - Make sure the connect point is good. - No over charging to avoid burn damage to chip.

Have my doubts...
Not sure about these, not fully tested yet. The so called TP4056 charging board in the description and product shot shows a chip labelled TP suggesting it’s the original NanJing Top Power chip, but what you actually get is a TC4056A which is a clone. Charging and discharging Li-ion batteries should be done with great care, the original TP4056 does this well within the spec required for Li-ion/LiPO. If you overcharge by the smallest amount you could damage the cell or even worse cause the battery to explode. Do your own research beforehand, “Google is your friend” ;-)
