My favorite Anker power bank with built-in cable is on sale at Amazon

I can’t ignore when one of my personal favorite power banks goes on sale—when it happens, I just want to tell everyone. Anker’s Zolo 20,000mAh power bank is on sale for $36 right now, a decent discount from its $43 MSRP and its most recent floor outside sale events.

The big draw here is the fact that it has a 20,000mAh capacity, which is enough for three to four full recharges of a flagship phone. That’s enough juice for a weekend getaway or a multi-day camping trip without worrying about your battery level running dry. It’s fast with 30W of charging speed, able to get a phone from 0% to 50% in half an hour. And with the extra USB-C port, you can charge two devices at once.

I’ve been taking this power bank with me to every concert I’ve gone to in the past year because I love how handy it is. With its built-in cable, I don’t have to worry about forgetting a cable and not being able to charge. Even better, the cable doubles as a carrying strap, so I can hang it on my wrist or loop it on my belt—my hands are freed up even without a bag. It’s compact with 4.72 x 2.89 x 1.23 dimensions and only slightly weighty at 0.78 pounds (pretty expected for a 20K power bank).

The only real downside is that it isn’t fast enough to charge a laptop, so you’ll need a bigger power bank for that. Otherwise, the Anker Zolo 20,000mAh for $35.99 is a smart, affordable choice for anyone who wants portable, reliable, and convenient power in a pocket.
