If multiple emergencies were to happen at once, this multifunctional external battery would surely come in handy. The Mini Power Tube and Extenal Battery Pack for Smartphones by DOCA is a USB-chargeable external battery, as well as an LED lit flashlight. This compact dual-purpose gadget will save you when your cell phone is dead during a power outage. The flashlight can last up to 36 hours.

Each 2200mAh cylindrical battery comes with a USB port that is compatible to charge almost all smart mobile devices. The external battery is also easily rechargeable. Made of anti-shock metal, the shells come in many different colors. The batteries are sleek in appearance and relatively lightweight, great for carrying around in your pocket or purse.
