The best power banks solve one problem: They’re always there when your phone dies. But the Anker Zolo solves a second, more frustrating issue—one most competitors ignore entirely. While other 20,000mAh power banks demand you remember a separate cable, the Zolo bundles a 6-inch USB-C cord into its design. It’s not just a convenience; it’s a game-changer for how people actually use these devices.
The cable isn’t just for charging. It also transforms into a looped carrying strap, turning the 0.8-pound power bank into a hands-free accessory you can clip to a belt loop, backpack, or pocket. No more digging through bags for a cable mid-concert or while waiting for a ride. No more tangled cords when you need a quick top-up. And no more carrying an extra accessory just to use the power bank.
This isn’t a gimmick. It’s a feature that redefines the category.
The tradeoff: Weight for practicality
At 20,000mAh, the Zolo is heavier than its 10,000mAh sibling—0.8 pounds versus 0.4 pounds—but that’s the cost of carrying everything you need in one device. The built-in cable means you’ll never be stranded without a way to charge your phone, tablet, or earbuds. It also means the power bank itself becomes a multi-tool: a charger, a strap, and a backup battery, all in one.
Anker’s 30W USB-C output isn’t the fastest on the market, but it’s more than enough for most users. A full charge for a 4,900mAh smartphone (like the Galaxy S24+) takes under two hours, and the power bank can handle three devices at once—two via USB-C and one via USB-A—if you’re charging multiple gadgets.
Who this is for—and who might skip it
The Zolo isn’t for minimalists. If you prefer ultra-lightweight power banks under $20, a 10,000mAh model will fit better in your pocket. But for everyone else—travelers, concert-goers, or anyone who’s ever fumbled for a cable in a hurry—this design is revolutionary.
It’s also a steal at current prices, which have dropped as low as $25.99. For $40 or less, you get a power bank that does the job of three separate accessories: a charger, a cable, and a strap. Few other products in tech offer that kind of integration for the price.
