18650 USB Battery Charger
Easily and safely charge and use 18650 rechargeable batteries with this neat magentic USB charger from PMD Way.
Simply connect the two magentic terminals to your 18650 cell, and the USB plug to a powered socket. The cable takes care of charging your battery at a rate of up to 1Ah.
Furthermore you can use the cable in reverse - that is, use the 18650 to provide 5V USB power via the cable's USB plug. Wow!
The LED on the cable blinks green when charging, and blue when the 18650 is being used to power a device.
Cable does not include a battery - however you can order one from here.
