One thing you should always have in your bag, backpack, or pocket—especially with summer coming up—is a portable power bank. You never know when your battery is going to fail, like when you’re stuck in the city and still haven’t Ubered home. Don’t have one? Today’s your lucky day. This Anker power bank is only $12.94 right now, which is 50% off for one of my favorite power bank designs of all time.

With a 10,000mAh capacity, the Anker Zolo power bank holds enough juice to charge your phone about two times over (more or less depending on the actual model of your device). The 30W charging power is fast, too, able to charge an iPhone 16 Pro Max about halfway in under 30 minutes. Plus, it’s about the size of a credit card and weighs under 8 ounces, so it’s extremely portable and won’t bog you down.

But the best thing about this Anker portable battery is that it has a built-in USB-C cable, alleviating you of the need to pack your own. The cable loops back and locks into place when not in use, serving as a handle of sorts that you can use to carry the power bank around. There are also extra USB-C and USB-A ports on the side, meaning you can simultaneously charge up to three devices with it.

The Anker Zolo power bank is an absolute bargain now that it’s 50% off and available for $13 on Amazon. Grab it before this deal ends!
