In some testing, the LithiumCard has been able to charge a smartphone two times faster than a standard USB charger, but that's not even the most impressive thing with the device. The most impressive thing is that unlike its competitors, the LithiumCard is about the same size as five credit cards stacked together, and is said to be small enough to fit into most wallets. Maker LinearFlux didn't just make it small though, it also has a 1200mAh battery, which is quite big considering the size of the device. It is compact, with built-in wiring, the ability to charge itself while it charges your device, and options for either micro-USB or Apple's Lightning connector.
If you think that sounds pretty interesting, you're not alone. LithiumCard finished an Indiegogo run last week which brought in almost $170,000, well more than the $30,000 that LinearFlux was looking to get in funding. LinearFlux will soon begin accepting pre-orders for the device, but there's no word on pricing yet. The device is about to start pre-production though, and is ahead of schedule for manufacturing, so it may not be too long.
