Anker’s 20,000mAh power bank with built-in cable is now $38 at Amazon

I absolutely love my Anker Zolo 20,000mAh power bank for two reasons: it packs enough charging capacity for all-day peace of mind, and it has a built-in USB-C cable that doubles as a carrying strap. That’s what elevates it above most other power banks I’ve tried. Right now, it’s on sale at Amazon for $38, only a few bucks more than its lowest price ever.

I’ve had this power bank for a while now and it’s still my go-to option when I’m out and about for a day. The 20,000mAh capacity is enough to charge a smartphone about four times—or four different phones fully one time each, which is great if you’re out with friends or family and they all want to mooch some battery power.

But my favorite thing about the Zolo is that built-in USB-C cable, which delivers 45W of charging. That’s fast enough to charge a smartphone from zero to full in about an hour, and I don’t have to worry about carrying a separate cable. With the extra USB-C and USB-A ports, the Zolo can charge up to three devices at once (you will need extra cables for those).

It’s a great little power bank that has paid for itself several times over. Now that it’s on sale for $38, it’s worth grabbing if you value speed and convenience. The one big caveat is that it isn’t fast enough for laptops. For that, you’ll want one with higher power output, like this Anker Laptop Power Bank that can hit up to 165W.
