- Reviewed in the United States on July 15, 2021I need a newer power bank to replace the previous Anker powercore i had and thought best to go for another Anker brand. Must say the 2 main reasons for my decision was due to my past experience with their products being great as well as their customer service when things didn't go well with the items ordered.
The charging brick for the powecore essential 20000 I got in the package would not charge it, even after trying multiple outlets and ensured the cable was connected properly. I then tried using the charging brick with my iPhone and it charged just fine but for some reason it just would not charge the powercore it came with in the order.
I reached out to Anker and I got a response within hours. Two emails later and they agreed to send another charging brick to have my issue resolved. After receiving the new charging brick everything works as it should now. Even though both the Anker iQ charging bricks look exactly the same, the older one just won't charge the powercore. This little charging brick is really something for it's size, easily fits into your pocket or purse and it provides really quick charging. it charges my iPhone XR alot faster that the regular adapter and my iPad the same as the 18W adapter it came with which is alot bigger.
Key things to note:
- The adapter is only USB Type-C supported, Your old charging cables wont work with it
- The powercore can charge 2 items the same time (1 USB type-C and the regular Type-A)
- The charging speed of the powercore is exceptional, just as you would get a charge from the wall outlet.
- Reviewed in the United States on March 7, 2023This power bank works great. It charges my stud fast and it last. Highly recommend this one! It’s a little heavy but I love it.
- Reviewed in the United States on March 8, 2023BESt for: travel, backpacking, camping for multiple days/multiple small devices
Not great for laptops (you will be better will something with more than 26000mAh
PROS: universal compatibility for cables and also also for devices, easy to see if you have enough charge left (each dot seems to represent 1 full charge for the phone). able to charge more than one device at once. My pixel is able to charge 5 times fully with this, and I can also charge my garmin in reach mini, It charges devices really fast (20 min), reliable, durable, hard exterior wont break easy. able to be charged in the car.
CONS: it is heavy/bulky, bigger/longer than a phone. To recharge it fully again, it takes a whole night, so you have to plan ahead
even with it being heavier, i still prefer to carry this one over the lighter one, even for day hikes
- Reviewed in the United States on November 28, 2020I love Anker products. All of my cables, chargers, and most of my power banks are from them. I already have a few small power banks from them and decided to buy this one when another brands large capacity started to fail. The banks physical size it just right, comes with a rapid charger, and holds a great charge. The trickle charge option is great too. Comes with a nice bag to protect it. This power bank is now the best one I own and well worth the cost.
- Reviewed in the United States on August 9, 2021It did the job without any issues. It is extremely sturdy. Super easy to use. My wife really likes it. She charged her phone while at the hospital with me during my hip replacement.
On top of that…it comes with everything you need to charge your phone. It comes with the charging cord for the wall and the device. Everything you need to charge you phone was included. Thank you! A+
- Reviewed in the United States on August 23, 2020Worked well for a couple weeks, but now has started randomly turning on and off while charging my phone. Amazon has shipped a replacement. Will share an updated experience after I get a chance to have it longer.
Update 11/24/20: The first replacement behaved the same. Worked well for a few weeks, but then started cycling on and off. Probably not good for my phone's battery to start and stop like that so much.
Anker reached out again asking for info about what phone I was using and more details. I have 2 Samsung S10's that behaved the same way. Didn't matter which charging port I used.
I took them up on an offer to send me their 30w version. It is skinnier than this one, but basically works the same. It's nice that it does charge in half the time. It's been just about 3 weeks now and I haven't that problem come up yet. Updating from 2 Stars to 4 Stars because of very proactive customer service! This is the first time that I've ever had problems with an Anker product. If I don't update this again, it means that the 30w version continues to work well for my S10's.
- Reviewed in the United States on December 30, 2021I can play multiplayer online Monster Hunter Rise on the Switch with it plugged into this Anker and maintain 100% battery. For those who don't know, that game, especially online, will drain a Switch in about 2 hours if you're lucky. This Anker is the perfect traveling and convention companion. It takes a while to charge up though so plan ahead. I would absolutely buy it again.
- Reviewed in the United States on June 23, 2020This is not your average powerbank due to its large capacity but nonetheless a great addition if you are going on long trips. I have other powerbanks but still bought this since it will be great when I’m traveling for long hours due to its large capacity. it can also fast charge my iphone 11 pro max, making it an ideal powerbank when you know an outlet will not always be available. Aside from my iphone, It also fast charges my ipad pro 11, which i always bring with me as long as i have the necessary cables. This anker powerbank also includes a charger, making it more value for money in the long run
