Approximate project cost: <$10 Max print dimensions 81 x 32 x 41mm Never run out of power again! This easy-to-print and assemble USB Backup Powerbank, equipped with a lithium-ion 18650 battery, will recharge most of your commonly used electronic portable devices. It's charged via a micro USB cable (5V, 1A input) and features two USB outputs (1.0A and 2.1A). The inbuilt overcharge and short circuit protection allows you to use a standard 18650 lithium-ion battery. A blue back-lit LCD display shows the percentage state of the battery pack, while an LED flashlight on the end provides extra illumination (simply double-click the button to turn it on/off). This is the perfect portable accessory for your pocket or purse when you're out and about and unable to recharge your phone!
