It’s extremely hard to beat Anker’s A1695 “InstaCord” 25,000mAh portable battery when it comes to value and price, especially now that it’s 20 percent off thanks to Amazon’s Big Spring Sale. Originally $109.99, it’s currently available from Amazon and Anker for an all-time low $87.99 — not bad considering the high-capacity power bank offers 165W of total charging power and not one, but two retractable USB-C cables built in. One doubles as a sturdy carrying loop, while the other is embedded near its ports on the top.

The battery was a recent star in The Verge’s fun Today I’m Toying With video series, in which our own Sean Hollister heaps some praise onto the InstaCord battery. Something cool about its built-in cables is that they’re bidirectional, meaning they can charge devices and be used to charge the battery itself. Anker usually comes out with at least one must-own portable battery per year, and so far, this is 2025’s top candidate.
