Tiny Battery Charger
DESCRIPTION
This is a standalone Lithium battery charger which lets you charge up your batteries from a micro USB cable. The battery can connect to a JST SH connector (the battery connector on the batteries that we sell at TinyCircuits). You can also use this without the JST connector with two large through holes to connect to a battery pack.
Simply plug the USB side with a cable into a USB port, and plug a lithium polymer or lithium ion rechargeable (3.7V / 4.2V) battery into the other side and it will start charging. A status LED on the board will indicate when charging, and will turn off when fully charged.
Note: The battery and the microUSB cable are not included.

It actually plays my old home videos on a screen the size of a stamp. It's my desk's favorite object.
The remote is absurd and I love it. Setup took five minutes and my clips looked crisp on that little screen.
Build quality is unreal for something this small. Feels like a real gadget, not a toy — and it's made here.
Gifted one to my brother and now the whole family wants one. Tiny, but seriously mighty.
Battery lasts through a work day on my shelf and the fireplace loop is weirdly cozy. Zero regrets.
Loading my own videos over USB was dead simple. It's the best desk conversation-starter I own.
