Real talk: How did we ever live without cellphones?
These days, if you let your battery die for five minutes, you’ll miss out on a billion texts and news updates, not to mention your mom will probably spam the family group text asking if you’re alive.
Save yourself the embarrassment and inconvenience of a dead phone by grabbing the LithiumCard Wallet Battery . This fan-favorite aluminum pack can charge your device at up to 1% battery life per minute, so you don’t have to sit by an outlet praying for the screen to come alive again. You can even charge your LithiumCard while charging your device, so you don’t lose juice at any point.
This sleek battery fits into pretty much any wallet due to its fantastic design, which makes it no thicker than five credit cards. (And if it doesn’t fit in your wallet because your wallet is way too tiny, you can stick your device to anything using the NanoStik pad.)
For most of the year, the neat LithiumCard Wallet Battery retailed for about $60, but it’s on sale for just $20 right now . Plus, Mashable readers can use the code BESTOF17 at checkout to get an extra 17% off.
