LithiumCard is an ultra-fast external battery charger that has been labelled the world's only rechargeable HyperCharger. Developed by California-based company LinearFlux, the HyperCharger sports a high-speed charging technology that its inventors claim can charge devices faster than any competitors.
The device uses 'HyperFET' charging technology, which calculate's the device's optimal charging profile. This allows it to deliver up to a 1% increase in battery life per minute. In other words, the HyperCharger can produce 15% more battery life in 15 minutes than a regular charger.
Despite its heavy-duty performance, the LithiumCard is about as small as a credit card and only slightly thicker, so it can be carried around in a regular wallet.
Interestingly, the LithiumCard HyperCharger can simultaneously charge a smartphone, tablet or any other device that accepts Lightning or microUSB charging and charge itself, as long as it is connected to an external power source via USB. The LithiumCard supports iOS and Android devices.
