Anker’s 87W power bank with built-in USB-C cable is just $50 today

One thing I always carry in my bag is a power bank. My phone’s battery isn’t uber-reliable, so it’s peace of mind knowing I always have a backup battery on hand. If you need a backup battery that packs a lot of capacity and is fast enough even for laptop charging, you’ll love this deal: Anker’s 20K 87W Power Bank is now just $50 at Amazon.

The star feature of this power bank is the built-in USB-C cable, so you don’t even need to pack a separate cable with it. But it also has extra USB-C and USB-A ports, allowing you to charge up to three devices at once if you do have extra cables on you. That comes in real handy whether you need to charge your phone, laptop, and earbuds, or when your friends’ phones are dying and need to bum some charging.

The 20,000mAh capacity of this power bank is enough to recharge a flagship phone about four times, and the 87W total output is fast enough for charging a laptop even while it’s in use. (Note, however, that the single-port max is 65W through the built-in USB-C. Still fast, but maybe not fast enough for the most power-guzzling laptops.)

The one big downside here is that this power bank is pretty chunky, measuring 6.2 x 2.9 x 1.0 inches and weighing about a pound. Not exactly the kind of portable charger to slip into your pocket. But it’s great if you can slip it into your laptop bag or backpack. Get it on sale for 29% off at Amazon while you can if you’re interested.
