Customer Ratings & Reviews

I hardly do reviews but I needed a charger for when we went to Disneyland 2 weeks ago. We used max pass and I needed to have charged phones to get fast passes and to keep in touch with my kids 16 and 19 who did a lot in their own. We were all able to fully charge our phones at least one time throughout the days we spent there. It charges very quickly and we were never able to fully deplete the battery yet. The bag it comes with is also great. I keep a lightning cable and another cable to charge the portable in the bag. It stretches so it’s easy to insert and remove the cables from the bag.

I purchased this because I was tired of having to add earphones or low battery on my phone as I practically live at the gym and always need both pair of headphones fully charged as well phone . When I first unboxed and pulg to charge to several hours, also little weight but not a nuisance like a brick as well Has a fast paced USB port and a regular as well as it shows you how much juice you have by the blue dots and has auto shut off/on .I love it I have no complaints and holds juice very well

I use this for vacations, camping and in general. Long lasting life & it can charge multiple phones at once. The recharge time is also quick.

I bought this battery bank so I could have a faster, long-term option for keeping my devices supplied. I found this bank very useful. It does take quite a while to charge it up fully, but it works as advertised, fully charging my phone seven times before needing a recharge. The 2.1A port is good, not as fast as my 10W iPad charger. One thing to note is that the user needs to push the button on the side before the unit starts charging a phone, it will not just charge with a cable attached.

Trust me, buy this and the 5 port Anker power Adapter. you will NOT be disappointed, Charge this overnight using the 3.0 port on the Adapter, this thing will charge your phone multiple times. We used this on a recent 15+ hour trip, and the girls in the backseat were able to charge their phones while we had the Garmin plugged into the 'smoke hole' (as my son calls it) in the front. This charged 2 android phones multiple times and we never had to worry about their phones dying

I bought this for an upcoming trip to Greece where I’m not sure I will always have access to charging my phone while out touring during the day. Since I use my phone to take pictures, the battery goes down fast. I’ve been using it at home to see how it’s going to work, and it seems to charge an iPhone very fast. And with only one charge to this product, I’ve already charged my phone several times. I think this portable charger is going to work perfectly for my needs.

Only "con" to it is it's a bit heavier than the typical portable charger but as fast as it charges and keeps its own charge that's not an issue at all.

I have purchased two of these over the years and will continue to get more if I need them. These batteries are top quality that last and last and last. The IQ automatically senses what type of charge your gear needs and takes care of the rest. I don't use any other brand other than Anker because I have never been let down a single time in the many years I've been using their gear. This PowerCore is amazing and I stand by it.

This battery is small and light to be easily carried to trips, and it holds enough power to charge my phone. Well made, good quality.

I am constantly running low on my phone battery and this portable chrarger is the answer to my prayers...it does what it says...charge up to 7 full battery, i dont have to worry about running out of juice anymore...other charger that i have used...and i have used almost all the brands that there is out thereand so far this is the best one ever. The only con is that it is kind of heavy but other than that it is the best charger i have ever used

This Anker PowerCore Portable Charger is great for individuals or families on the go. We purchased this portable charger specifically for our 3 younger kids while we are traveling to their older siblings sporting events where outlets in gyms are not always easy to find. This Anker PowerCore Portable Charger is small and comes with a nice mesh carrying case that you can put your power cords in so that you don't loose them. This charger can also charger multiple items at once and provides a quick charge.

If you’re on the market for a portable charger get this one!! The Anker PowerCore is awesome!! It’s heavy so it’s not the best thing to lug around all the time but it’s long lasting and fast! I fully charged it around May 24, 2019 and I’ve used it dozens of times to recharge my work phone and personal phone since, and guess what as of now (June 18th) it still has two bars. I’d say that’s pretty awesome considering most portable chargers drain after one or two uses. I’d definitely recommend buying yourself one!

Even though this isn't the newest tech of it's kind, it's my first powerbank and I'm really liking the convenience it provides. With the pixel 3a xl this thing is just fine, however, the Note 10+ that I'm using could likely benefit from the best powerbank available with 3.1 and PD. If they make one with PPS, then that would be the best option for the Note 10+ obviously. Oh and the price was great on the daily deal combined with my $10 credit sent to me randomly. Value buy without a doubt!

I purchased this due to that fact that I was on a crabbing trip and my GoPro battery died and I could not use it the rest of the day.... I seen it advertised on sale and started reading up about this potable charger and it was a no brainier... since charging it I have charged my cell phone several times along with charging my Osmo Pocket several times and had let several co-workers charge their cell phones well... and I still have three lights left on it... it does take several hours to fully charge but I watched several YouTube videos on how to speed up that process one was using an iPhone charger but I have only charged it once since I bought it so I may have to edit this after I charge it back up to see if the IPhone charger is quicker. One thing is that it is large and heavy but for me i carry a backpack to work and everywhere i go so it is not an issue to me as it may be to other... overall so far this has been a great purchase and i am please with this portable charger so far....

This is a terrific charger. Holds enough charge for several items. We purchased it for minor emergencies. Loss of electricity. It holds its charge very well. One negative is it’s a bit bulky for a purse. So we put it in glove box.

I love this portable charger. It's compact (but a tad heavy) and stays charged for a very long time. I don't leave home without it.

works well. used it for over 15 times. have not failed me once in charging or using. its heavy and little big when i carry it on my back pocket. it fully charge my note 8 (from 27%) any my girls iphone 8 (33%) and left about half charge. worth getting if on sale .

good capacity, good material, take time to charge but it has 20,000mah so you know, can charge phone fast and multiple times

I've been using Anker products for about 7 years now, and I've yet to purchase anything that doesn't meet AND exceed my expectations. This is a pretty big power pack but it's not super heavy to I carry it with me when I travel or hike to keep my electronics (phone, cameras, etc.) charged. It doesn't get very hot like other chargers do. It is perfect for carrying around anywhere you go, and provides several full charges to a mobile device when it's fully charged.

This purchase was a hard decision since I've gone through so many portable chargers that haven't worked well. I read the reviews and took a chance. It's a little heavy, but it has a nicer carry bag than others I've purchased. The reviews I read were correct...takes quite a long time for the initial charge, but it charged both of our Pixel phones quickly. I already purchased a second one as a gift and I'll be using the 5 port adaptor I purchased soon for an upcoming trip.
