Adafruit USB Battery Pack for Raspberry Pi - 3300mAh - 5V @ 1A and 500mA

A massive rechargeable battery pack designed for versatility, capable of powering anything requiring 5V, including Raspberry Pi, Arduino, Propeller, and more. Originally intended for smartphones and tablets, this pack excels at juicing up small computers and micro-controllers.

It houses a 3300mAh lithium polymer battery, a charging circuit, and dual boost converters offering 1 Amp and 500mA outputs via USB ports. Perfect for the Pi, the 1 Amp output ensures seamless operation, even with accessories attached. We've run it with a 2.5" NTSC display, a wireless keyboard/mouse, and a WiFi dongle, creating a compact computing station without any hiccups.

Duration varies based on connections, but a headless Pi with a WiFi adapter lasted up to 5.5 hours when pinged continuously. Monitor power levels easily with a 4-step LED charge status display and an on/off button for control.

This comprehensive package includes the battery pack, a convenient fabric bag, a USB extension cord, a mini-B cable, a micro-B cable, and an Apple 30-pin cable, making it an all-in-one solution for portable power needs.
