Customer Ratings & Reviews

I can charge my phone 5 times before this battery gives out. It also charges my phone fully within 30 min which is faster than any car charger port or other battery packs. I take this thing with me everywhere cause you never know when you might need it. Slight weight to it, but still portable.

Bought this last minute before our vacation. Charged our 3 phones throughout the day with spare juice at the end. Works great, especially the USB-C option. It’s only slightly bigger than a phone, a little heavy but expected since it has a larger capacity.

The Anker PowerCore 3 is a reliable portable charger that combines high capacity with fast charging capabilities. With multiple ports, it allows you to charge several devices simultaneously, making it perfect for on-the-go users. Its compact design ensures easy portability, and the durable build adds to its longevity. The inclusion of PowerIQ technology optimizes charging speeds for various devices. While it may lack some advanced features found in other models, its performance and affordability make it a solid choice for anyone needing reliable power.

This charger is somewhat heavier than expected, but I like to overall slim design. It charged up fairly quickly and provided charging on my smartphone within a reasonable time, and it didn't take up too much battery life.

This charger is a really reliable, long-lasting option. Compact enough to fit in your pocket, but with a great charing capacity.

Best power banks out there. Anker is known for making good quality power banks and this one is no exception! It charges pretty quickly in about an hour or so and can charge your phone in my case an iPhone 13 3 different times to full battery! That is insane power for something so small! Also it is very reasonably priced there’s a lot of other power banks on the market for the same price point but the brand and the MAH of the bank is definitely what should be looked for and this one has it all!

This is a fantastic charger. After it's first initial charge via USB to my computer, it was able to rapidly recharge my cell phone three consecutive times. It probably could have gone a fourth but I hooked it back up to recharge. I like using it in my car to keep my phone charged while driving around. I am extremely happy. If there was any con traits, I'd probably mention that is is heavier than my last one, but I'll easily take the tradeoff.

I took Anker PowerCore III on my last trip to Vegas and loved it. It had plenty of juice to keep me powered thru all my visit there. It fit neat on the side of my backpack. I recommend everyone to have one of this when on trips!

I love its large capacity, and the fact that i can use my usb c cable to charge both my phone from this charger AND use the same cable to charge the power bank. This is something that is not common in a lot of batteries but this has it at a great price point. It's been 1 1/2 months and it still functions like new!

Good, reliable charger. We own Pixels in our home (Pixel 3 and a Pixel 6) and it charges these devices rapidly. Great for portability. Best for those who are looking for someone to charge multiple devices as the charger is heavier than others. I cannot comment on just how much charge it holds but based upon my first couple of partial recharges (I seldom let a phone get down below 20%), it seems to be quite significant.

I purchased this because I left on my way to work without a phone charger. This actually wasn’t much more than if I were to purchase a charging cord and wall plug. Plus I already had several of them at home. I’m glad that I did. This charged my phone a lot faster then the wall cord. It’s extremely sleek and can fit in my front pants pocket. And can charge your phone a few times before needing a recharge.

Does exactly what it's supposed to: it's a rechargeable battery with some USB ports. It does take awhile to charge, but that might be the adapter I was using. Otherwise it charged my OnePlus 7 Pro just fine. This strikes a good balance between capacity and physical weight, especially for traveling. Also it looks neat. Also also the little blue lights are pretty

On a full charge, my family was able to take turns using this to charge all of our devices several times each on our 20+ Hour trip from Texas to California for vacation. This holds a pretty incredible amount for its slim design. Just overall convenient and serves its purpose for the price!

Just luv Anker products. Very well Built, Compact, Sleek Design, Fast Charging on both ports. Charge life left it sit for a week and still held a charge. If you want a well built product and one that does the job you can't go wrong with Anker products. Even works great with my Raspberry Pi 3 B+, just luv it... Definitely recommend don't go nowhere with out it anymore..

Simple to use, thin and works good. Charge multiple items at one time.

I really enjoyed the powerbank as it lets me charge on the move It’s a really good price for the capacity it provides Compared the other power banks it’s been really amazing in areas such as charging speed, as well as capacity to charge multiple devices

I purchased this power bank in May of 2022 to travel overseas when I knew I would be taking alot of video on my phone, which I totally did. This power bank was phenomenal! It kept my phone charged on some long, 12-14 hour days under very strenuous use and high temps, with power to spare. I was glad I opted tor the 20 maH. Sometimes the available power outlets in the country I was in weren't always reliable and I couldn't get a good charge on the power bank overnight, so that it would have to rely on the charge from the night before... and it did! I was amazed how much juice this thing can hold. It's now been about 8 months since I bought it. I have traveled with it a few other times since then, and dropped it several times. It's built like a tank and keeps going, no perceivable loss in performance. Of course, it requires alot of time on a charger to fill up completely, but that's understandable, considering how long it lasts.

I bought this product while visiting NYC. This portable charger was the perfect size to fit into my fanny bag. It was fast charging and maintained a charge for over 96 hours. I highly recommend this product.

I travel lot and I have two of these with me at all time. Very reliable and durable. I had the old versions too! I love and trust anker for power bank and they never let me down! They’re little heavy I won’t lie :|

I recently went on a family trip and was looking for the best Power Bank solution for my Nintendo Switch and Samsung Galaxy S21 +. Look no further! This product is exactly what I needed! Don't spend the extra money on the officially licensed Nintendo Anker Power Bank. This one is the exact same thing and is much cheaper! It works perfectly on both my devices and even works on my Galaxy Buds Plus! Been taking this with me on the go to campus and it has not let me down. Charges my devices pretty quickly. What I love most about this product is that it comes with a sleeve for your power bank. Great for putting in your backpack or bag to take with you! One side note is that you will need a usb->wall charger to charge your power bank. Charging the power bank does take awhile but I usually leave it charging overnight and it's ready to go when I wake up the next day. Overall, fantastic product and I'm more than happy with my purchase!
