It’s simple: everyone needs a good portable charger. Even if you have a giant phablet, the battery life on your smartphone still isn’t where you want it to be. Smartphone battery life may never be good enough to truly keep up with our needs, but that’s why portable chargers exist. And for a limited time on Amazon, you can enjoy big savings on two great portable chargers.

First up, we have the Rugged Water/Dirt/Shockproof UNIFUN 10400mAh USB External Travel Battery. This puppy packs a gigantic battery that will charge your phone four times or even more before needing to be recharged itself. It can also take a beating, and it has a built-in flashlight.

For a limited time, you can save an extra $5.49 with a special coupon code.
