We love the peace of mind that carrying around a portable battery pack gives us. We don't love the extra bulk. So it's no wonder we're big fans of the LithiumCard wallet battery, a super-thin battery solution that fits in your wallet. Does it get more portable than that? Grab it for $20 at TweakTown Deals.
The thickness of just five credit cards and weighing just over 1.5 ounces, LithiumCard packs a surprisingly powerful punch. Charge your iOS device at up to 1% battery life per minute-you can even charge the LithiumCard itself while it charges your device. No room in your wallet? No problem. LithiumCard also comes with a NanoStik pad that allows you to attach it directly to your device (yeah, they thought of everything).
