    I purchased this as a gift for my partner's 70th birthday. He immediately said it is great and works just like it is supposed to work. A hand-held device that charges your phone as you carry it. Quite the nifty idea. Highly recommend this device for yourself or as a gift. You will not be sorry.

    BEST PORTABLE CHARGER

    It’s an excellent charger and it has a long life. You can charge your electronics over 5-7 times. Only thing is that it takes a while to charge back but you can leave it overnight and it would be done. EXCELLENT product, the best portable charger I’ve ever had. I bought this one as a spare since I have mine since 2021 and still works perfectly.

    Relatively small and lightweight. Charged my Samsung S 21 Ultra from 62% to 90% and the Anker still showed all 4 status lights indicating it was near 100% charged. I'm keeping this!

    I have had one of these already for a year or so, but after a recent power outage (over 30 hours), I decided to get a 2nd one as it can charge a phone a couple of times before needing to be charged itself. I only get Anker portable chargers. It also holds a charge for weeks at a time, so if ready when needed.

    Compact design. Charges in about 6 hours and holds it reasonably well. It is still new and cannot comment on the longevity of the product or capacity after multiple charges.

    I am absolutely impressed with Best Buy and the Anker PowerCore III Sense. I ordered this item online Nov 8th and it was delivered to my front door on Nov 9th! I unpackaged the PowerCore and it was in perfect condition. I proceeded to charge it up (it had a 50% charge as shipped). It took about 5 hours to reach a full charge (4 lights). I have charged my iPhone 13 Pro 2 times and the charge remains at 4 lights lite. I am very happy with this power bank and definitely would recommend it to anyone who wants a backup battery source.

    Purchased the PowerCore 3 USB-C portable charger for a camping trip. It worked great and came approximately 65% charged. We were able to charge 2 phones from the start before needing to charge from empty. Usually its not recommended to use anything electric from the start without fully charging it however, when youre in the wilderness, you do what you gotta. Pleased with the purchase and the reward points used.
