There are a ton of backup batteries for our devices out there. You can get plain black boxes, cute characters or compact energy sticks. What all of those have in common is that they need to charged before use. The ResQBattery is the disposable phone power pack that’s ready to go, right out of the box.

This little power pack is single use only. Open up a pack and it will charge your phone for up to five hours of talk time, which is to say, it won’t bring your phone back up to 100% if you’re wallowing in power saver mode, but it will provide you with enough charge to, hopefully, make it home.

As mentioned before, these are disposable, once you’re done charging, feel free to toss it. They come in a variety of brightly colored options making them easy to find in bags and emergency packs. They have a shelf life of five years so don’t worry about using them right away, they’re there if you need them in an emergency. The ResQBattery are $11.99 for a two pack.
