If you rely on mobile devices all day, every day, then having a power pack with you to top them up when they get low on juice is a must. And despite what you might think, they don’t have to be big, bulky units that weigh down your bag.

Take the LithiumCard, for instance: It’s small enough to fit in your wallet and it boasts HyperCharging technology for rapid power when you need it — and thanks to Cult of Android Deals, it’s just $39.99 (down from $55) for a limited time. But you’ll have to act fast to take advantage of this awesome offer, because it’s ending soon!

The problem with having giant touchscreens on our smartphones and tablets is that they’re often plastered in fingerprints. And with fingerprints, there is almost always germs.

The safest, fastest, and most effective way to keep them at bay is with the Mobile Cloth cleaning pack, which is just $11.99 for a limited time, thanks to Cult of Android Deals.
