For mobile warriors on the road who need to be connected but are tired of their batteries dying, the Vorson Arc 4k II Battery back up is a godsend. Vorson New Arc 4K is a super-thin battery backup for Android and iOS devices.
They use CNC unibody fabrication techniques, which is the same thing used in aerospace and for Apple Macbooks. Additionally, they use Lithium-Ion Polymer batteries, which can be poured and molded into any shape or size allowing them to create extremely thin and compact designs so you’re not stuck with something bulky and frankly, ugly, not to mention too heavy to carry around.
With a 4000 mAh capacity and dressed in shockproof 8mm thick aluminum alloy chassis, the New Arc 4K can give your device up to 20 hours of additional video playback and travel conveniently wherever you need it. There’s also a color coded LED charge indicator to help keep track of remaining charge, preventing you from being stuck without power ever again.
Using a high-grade Lithium-Ion polymer battery, it comes in four colors: black, white, silver and red. It is compatible with iPhone 5, iPad 4, iPad mini* and iPod touch (5. Gen.). The Lightning to USB cable is not included. It is priced at $99.
