## Description

Here's a hand-held-size rechargeable battery pack for your Raspberry Pi (or Metro, or anything else that uses 5V!). This pack is intended for providing a lot of power to a smartphone, tablet, etc, but we found it does a really good job of powering other miniature computers and micro-controllers. If you want even more power, we have a 10,000mAh power pack with two USB ports that can provide up to 2A!  Inside is a 5000mAh lithium ion battery and boost converters that provides two USB A ports with 5VDC up to 2.1 Amps. Great for single board computers like Raspberry Pi The charging circuit will draw 2A from a 5V supply (plug a microUSB connector into the pack and then to a computer or wall adapter). You can charge and power something at the same time but there's ~80% efficiency loss on both ends so if you charge it at 1A and draw 1A at the same time, the battery pack will eventually go empty. However, if you're powering something that's 500mA or less, you can keep it topped up no problem. Also, when you start and stop charging the pack, it will flicker the output, this can cause a 'power sensitive' device like the Pi or an iPhone to reset on the power supply. If using it with a low current load, say under 100mA, the pack may 'fall asleep' - you can use this circuit to keep the pack awake.
