Most people rely on their smartphone to get them through the day: from responding to urgent work emails to texting your family to scrolling through social media on a long commute, we need our phones, and we need them charged up. Until battery technology catches up to the technology that created the computers we keep in our pockets, carrying an extra power pack is a must-have. Finding one that charges your phone quickly and safely at a reasonable price isn’t easy, but the Extreme Boost 20,000mAh Back-Up Battery has your back when you hit that dreaded 5% mark on your smartphone.

This backup battery boasts Smart-Charge Technology, which automatically adjusts the charging speed for up to four devices simultaneously. You can power up safely without worrying about overcharging, using too high of a current, or short-circuiting your phone or your power bank. Its impressive 20,000mAH capacity can charge multiple devices multiple times without needing to plug the power bank back in, allowing you to keep all of your gadgets running for hours. Plus, the Extreme Boost is roughly the size of a smartphone, so it’s easy to carry with all of your other gear.

Normally the Extreme Boost sells for $89.99, but right now it’s 60% off for a sale price of $35.99.
