Ventev Powercell 10000+
You can count on a backup power pack to carry a fair amount of juice, but when it comes to the necessary charge cables or a method to charge the pack itself, you’re typically on your own. Ventev’s Powercell 10000+ is the first we’ve encountered that does double (or triple?) duty thanks to its built-in, fold out Lightning and Micro USB connectors that deliver its 9,000mAh battery capacity straight to your gear. It can also charge up to two devices at once, boasts a USB port if a different charge cable is needed, and sports folding AC prongs to plug straight into a wall socket for charging.
