Anker’s Laptop Power Bank is one of the more useful gadgets I’ve bought in recent years. I know, it’s just a portable battery, but it’s packed with power and thoughtful features that are tough to find in other models. And right now, you can buy it for $95.99 ($24 off) — the best price of the year so far — at Amazon during its Big Spring Sale, from Walmart, and directly from Anker through the end of today.

The 25,000mAh / 90Wh power bank features three USB-C ports and one USB-A port, and you can get up to 130W total output when using all four ports. If you’re only charging one USB-C device, this power bank can deliver up to 100W, which is enough to quickly charge the latest 14-inch M5-powered MacBook Pro. Plug in two USB-C devices, and it can go all the way up to a combined 165W.

As nice as the power is, Anker’s power bank really stands out thanks to its two built-in USB-C cables — one of which is a retractable 2.3-foot cable, and one that doubles as a carrying strap. In terms of other niceties, the power bank includes a small display that shows how much charge is left, the battery’s overall health, and how much power each port is delivering. And since it meets airline carry-on requirements, you can bring it on flights and use it to keep your devices powered while you travel.
