Black Friday shopping isn’t for the weak — with thousands of gadgets, gizmos and gifts on sale, it can be hard to figure out what deals are actually worth it. Good news: one of our all-time favorite portable chargers is on sale and it’s one of the best tech purchases you can make, according to NBC Select reporter Harry Rabinowitz.

I found, vetted and wrote about every Anker deal I recommend below. I worked with NBC Select reporters to finalize the live list, which I’m frequently updating throughout Black Friday to reflect the most up-to-date prices.

Anker 523 PowerCore Slim 10K

4.4-star average rating from 11,705 reviews on Amazon

“This portable charger goes with me everywhere — it’s been to four countries and has saved me from having a dead phone in countless airports, hikes and far-out bike rides,” says Rabinowitz. “It’s about the same size as my iPhone 15 Pro, and fits easily into a jacket pocket, bag or backpack. I love that it has both a USB-A and a USB-C port, meaning it can use basically any cable I have to charge any small device. (It also includes both types of cable in the box.)”

It’s not a newer model for Anker, but it’s versatile, according to Rabinowitz, since it’s compatible with iPhones, iPads, Samsung phones and Google Pixels. It also has a fireproof exterior and overcharge protection, too, according to Anker.

Why trust NBC Select?

I’m a commerce editor for NBC Select who’s covered deals and sales for years. To evaluate the quality of this Anker deal, I made sure it’s at least 20% off and highly rated with at least a 4.0-star average rating from hundreds of reviews. I also ran it through price trackers like CamelCamelCamel to ensure it’s at its lowest price in at least three months.
