Customers are saying

Customers are delighted by the PowerCore III Elite's impressive battery life and fast USB-C PD charging capabilities. Its high capacity and build quality are also frequently praised, making it a reliable and versatile option. However, some users note that its size and weight may be a drawback for portability. The power bank's compatibility with various devices is another positive aspect frequently highlighted by customers.

    I recently purchased a power bank that I am pretty disappointed with. It only seems to take a charge and won't charge any of my devices. I have tried using different cables and charging ports, but nothing seems to work. I was really hoping for a reliable power bank that I could use on the go, but unfortunately, this one seems to be useless. I would not recommend this product to anyone looking for a functional power bank.

    the product was defective and best buy told me they could'nt help me since return window was expired. So they referred me to the manufacturer who made my life a pain since they didn't have a replacement in stock and their suggested substitute was inferior. It took me along time to get a suitable alternative but now even this one doesn't work either...Im dreading to call Anker back since i know how much trouble its going to cause me.

    Worked well for its purpose but after three months, it stopped charging my devices. You can charge the power bank but it will not charge or light up to show how much battery you have left in it. I’ve seen multiple reviews about this In the comments section that have this same problem. I can no longer return it or exchange it. Best Buy needs to take this product off the shelves and replace it with a new batch or a better model.

    I love Anker and have bought many products over the years but this particular charger sucks. It has connecting/disconnecting issues for my phone. I replaced it 2x through here and 3rd with Anker. The Anker replacement worked perfectly for 6 months now I'm sending it in AGAIN!

    It basically stopped working just a couple months outside the 18 month warranty. Such an expensive powerbank. I barely used it. It was literally the second trip i use it on. I contacted anker and thwy offered a 20% coupon on a new one. The audacity they have to even offer such an insult of an offer. Why would i spend another penny with a scam of a company. Never again.

    Stopped working Within a Couple of Months

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I wanted to like this product. I bought two of them when they were on sale so I could have a couple power banks for phones and computers that I could alternate solar charging. Unfortunately, both of them stopped working within a couple of months of fairly light use. I thought initially it was not charging due to not getting enough solar power, but I plugged them in to charge them until it said it was full and it would not charge the device, or if it was not fully charged it would automatically start trying to pull power from the device regardless of what port it was plugged into. I wouldn't recommend this product until they fix this problem as it seems from other reviews there's been similar issues.

    Dont buy if you plan to charge expensive gear

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    The Power bank not only failed on me after nearly 18 months. (so just out of warranty!) it also caused me to short out (caused damage) to two USB based electronic items, I would not trust this brand again. This is my second power bank from Anker. My first one was a different model. Don't buy if you are planning to use to charge expensive equipment like a camera. If its to charge a phone, you should be fine.

    This product is dead less than 2 years after purchase, and slightly outside of its warranty period. I attempted to charge it before a trip and it powered up but would not retain any charge. Device was used a total of 5 or 6 times over the past 20 months. Contacting Anker about the product resulted in a 20% off coupon to their store, but I'm going to give other brands a chance for my next purchase.
