MacBooks have fantastic battery life, but even so, you’re better off with a proper power bank in your bag. This Anker 25,000mAh power bank with a built-in USB-C is perfect—and it’s on sale for just $92 at Amazon, a 32% discount and within a few bucks of its all-time low.

This isn’t your typical power bank, but rather a multitasker’s dream. The power bank features two built-in cables: one retractable cable and one that doubles as a carrying strap. Besides all these cables, there are additional USB-A and USB-C ports as well, so you can fill up your Apple Watch or AirPods too. The retractable cable can extend up to 2.3 feet, so it can easily reach your laptop when placed on your desk. The strap-style cable measures just under one foot long, too, which is quite perfect. When running single-port charging, the power bank can hit 100W, but altogether, the power bank has a maximum of 165W output.

If you want to keep your Mac awake all weekend, this is a deal you shouldn’t sleep on, so grab the 25K Anker power bank for $92 while it’s still on sale.
