If you’re someone who spends a lot of time on their phone, then you’re probably also someone who gets stressed out while watching their battery life slowly descend into the single digits. Or maybe it quickly descends, and that’s even worse. While that’s fine if you live your life near an outlet for charging, not all of us do, and that’s why it’s so important to consider some portable power options.

There are some amazing devices out there to help you sort this all out, but if you’re someone with an iPhone, you get access to a few that the rest of us can only dream of. One such device is the amazing Anker Nano MagSafe Power Bank, which would normally cost you $55, but is down to $46 instead today. This discount won’t stick around forever though.

Power Forever

This mighty little power bank isn’t like other ones available. Heck, you don’t even have to use cables if you don’t want to. That’s because it can just connect to the back of your phone and stay there, all the while using wireless charging to keep your phone battery ticking on so much longer. While you might worry that would make your phone feel clunky, it won’t, because this is an impressively compact power bank. It means you’ll barely notice it, and it also means you’ll be vastly expanding how much use you can get out of your phone.
