That sinking feeling you get when you see your phone’s battery levels go red, knowing you’re still hours away from being anywhere near, can have an easy fix because this tiny Anker Nano power bank is only $19.19 right now at Amazon on Prime Day.

This is a super compact power bank with a 5,000mAh capacity that’s enough to give your phone a full recharge anywhere you may be. This is a power bank that I’ve been using for well over a year, taking with me anywhere I go, from concerts to day trips.

The built-in foldable USB-C connector is extremely useful because you don’t have to carry an extra cable with you. Just pop up the USB-C and plug it into your phone, and you’re good to go.

Of course, if you want to use a cable, nothing’s keeping you from doing it because there’s a USB-C port on the side that can be used for both charging the power bank and for recharging your gadgets. Both the plug and the port can deliver 22.5W of power, making this charger perfect for both iPhones and Android devices.

Go ahead and order your Anker Nano Power Bank for just $19.19 while this October Prime Day deal is still around. Check out the best tech deals we found this Prime Day, too, because there are tons of deals available.
