My favorite power bank with built-in charging cable is $33 for Prime Day | usagoldmines.com

It’s the last day of October Prime Day, which means it’s your last chance to take advantage of this discount on my favorite power bank. Anker’s Zolo power bank is on sale for $32.99 right now, which is just a few bucks higher than the lowest price it hit all year long.

What I love about the Anker Zolo is the built-in USB-C cable. I love that I can just pack this portable battery in my bag and not worry about also grabbing a separate cable. When not in use, that built-in cable doubles as a carrying strap, which is handy when I don’t have a bag. I’ve taken it to concerts, for example, and that loop kept it secure on me while freeing up my hands.

The next best thing about this power bank is its large 20,000mAh capacity. That’s enough to get 3 or 4 full smartphone charges—more than enough for a day trip or a night camping. And it charges pretty fast, delivering up to 30W of charging speed. Have other devices that need power? The Zolo has extra USB-C and USB-A ports, allowing you to juice up to three devices at once. Just note the 30W gets split when multiple ports are in use.

Keep it on you during your commutes and you’ll never worry about your phone dying before you get back home, and take it with you while traveling for use in airports. (It’s small enough to comply with FAA and TSA regulations.) It measures 4.72 x 2.89 x 1.23 inches and weighs 12.45 ounces, so it’s no problem to carry around.

You’ll need Prime for this deal, so grab a free Prime account and snag this discount while you still can. For more great deals, see the best Anker deals for Prime Day and best Prime Day tech deals on Amazon.
