Never run out of battery again! This easy to print and assemble USB Backup Powerbank comes with a 2200mAh lithium-ion battery that will recharge most of your commonly used electronic portable devices (it will give you a full charge back to your iPhone). It is charged via a micro USB cable (5V, 1A input) and has two USB outputs (1.0A and 2.1A). It has inbuilt overcharge and short circuit protection so you can use a standard 18650 lithium-ion battery. It also features a blue back-lit LCD display which tells you the percentage state of the battery pack (which is very handy) as well as an LED flashlight on the end! (Double click the button to turn the flashlight on/off). This is the perfect thing to put in your pocket or purse when you're out and about and unable to recharge your phone!
