Customer Ratings & Reviews

Battery pack doesn’t provide a decent charge. Best way to use my laptop is to leave it plugged into the wall

does not charge as fast as advertised— very slow product

Poor quality, the charger does not work for more than 2 months and I barely used it.

It doesn't work. It started not re-charging after only having it for a week.

this thing takes days to charge and is not worth having

Purchased refurbished. Never held a charge over 1-4 bars

The ANKER brand has become one of go-to for everything. This is my 2nd ANKER product and it did not disappoint! Solid, it works and I have no complaints. It is a bit too heavy duty for my needs; after a couple years I downsized to battery banks smaller and more fit for me…However, it took a couple years to swap it out and I was able to hand this off to someone else who appreciates it like it was brand new and still worth its original prices value!

Had 2 lights of charge when opened. Charged my S7 Edge for 1 hr from 17% to 65%. Neither phone nor Powercore were heated and 2 lights were still lit. Charged a 18650 battery (Ecig, flashlight style) from dead to 50% in 2 hrs and Powercore's last light was blinking. 18650 charger was slightly warm. Possibly low amperage? Charged Powercore to full in less than 11 hrs. Reviews, capabilities, and cost led me to purchase it and satisfied with its early performance. Intended for phone, battery, and portable speaker charging. Also added BB's warranty that gives 2 yrs of no problem replacement.

I have a RavPower 20100 powerbank and I wanted to have a spare for emergencies. This charger has a fast charging option that really does fast charge my Galaxy Note 9. This performs just as good as the RavPower, but this ANKER PowerCore is smaller and slimmer. It has a nice pouch that you can use as a cover for the brick. After a full charge, this powerbank charged my Note 9 5 times. Can't beat the price to performance ratio! Would recommend!

I got this at Best Buy this charging unit is great it is really powerful charges the phone really fast and it charges my phone at least two or three times on each fully charged unit I really like it it's really powerful and holds a lot of juice in it you can charge your phone a couple of times on one fully charged unit

I use this battery when I go snowboarding or just traveling and this charger charges pretty fast. But, not as fast as some of the USB-C chargers that are out now. But this battery holds a lot of juice in it and it lasts a really long time. This purchase was definitely worth the money.

This is one amazing charging brick for 50 bucks for a 20000 mah. The size isn't bad. I am an adult male and it can comfortably fit in a pocket. It is long though. But for 50 bucks. Having several charges handy if needed is a lifesaver. Can't go wrong with Anker products. Just with Best Buy had them located with the other chargers. Nothing but Best Buy and Mophie chargers by their phones. The employee didn't even know they had them, and they were in a weird location by themselves.

Great portable charger!! Gives several charges before it needs to be charged. It is a little heavy and does take time to charge, but both were expected.

Pros: Ability to get about 5 full charges, fast charging with Samsung Note 5, ok charges with usb to usb c Cons: Heavier and bulky, takes 9+ hours to charge

Bought this power bank about a month ago and I have to say it's been very well at supplying battery power to my cell phone and when ever I need charge on any other device when on the go so far I have been able to get 8 good charges on my note 8 not badd at all for a power bank only thing is that it can be a bit big but good tho.

I used this Portable charger in Las Vegas for 6 days for New years and it worked sooooo good. The best charger on the market. My friend & I charged both of our phones at once and never ran out of battery. The charger lasted 2-3 days and we used it a lot. GREAT!!! GET IT!!!

I bought this to take on Vacation to Costa Rica. This charger was great it remained charge during my excursions dom excursions were 13 hours long. It's not really small but I need a charger I could depend on.

One of the best power banks out there my still going and charging my iPhone it been a great powe bank

I ordered this charger for occasional use, mostly for when I forget to charge my phone before work. The fast charge feature easily charges my Note 9/S9+ phones in 90 minutes, just as if I used the original Samsung fast charger. I use the Samsung fast charger to charge my Anker power bank and it charged it in about 7-8 hrs. I love this power bank so much that I just now ordered a second one and I'll keep both charged, one in the car and one at home. Winters coming and there will be a few power outages. These will cover me.

I just absolutely love my portable bank. I can charge multiple times and still have alot of battery left.
