Great for arduino projects

Pair one of these with an 18650 cell & 3.3v arduino, and you've got a portable setup. Stick it somewhere for days/weeks to let it run, then come charge it up when it gets low. These little chargers are a great value, and function exactly as expected.

Great value, useful and well made

These are an upgrade to a couple of other TP4056A based chargers already owned. They feature a micro USB connector on the input, allowing a regular 1A cellphone type wall adapter to be used. Circuit construction is high, with no solder flow issues or barely held components. They work completely as described and top out at 4.2V, as expected. A good solid product.
