Credit Card-Sized Power-Ups: LithiumCard
The most convenient thing in today’s world, Power banks are undeniably useful and come in handy when you need to charge one of your mobile devices when you’re on the move. Unfortunately, most of them are too bulky and too heavy to carry around everywhere, 24/7, especially if you have to lug around your laptop among your other gear while you’re at it.
Here’s a worthwhile alternative: the LithiumCard. Not only is it the perfect power supply back-up, but it’s so sleek and compact, it fits easily in your wallet, right beside your credit card. It hyper-charges your phone via microUSB and charges up via USB.
