A typical device gains an additional 2-3 hours of run time, according to Electronista, and the Mobile version of the company's existing charger plugs into any USB device. The PowerAid Mobile ships with ten connectors to match the power demands of compatible devices, and the device itself can recharge through either an AC adapter or the 12-volt port found on many cars. US Modular expects the smaller PowerAid to ship this month for $50.
