I've had this thing since 2017. I LOVE it. Charges in about 6-7 hours and charges my phone multiple times. I like having the peace of mind my phone isn't going to die halfway through the day since I'm bad about forgetting to charge it at night. It has traveled internationally with me as well as gone on camping and fishing trips. I didn't get questioned by TSA if that's a concern for you, just pull it out and put it with your laptop. My only gripe is that it is a little cumbersome/heavy but that's to be expected for the amount of power this thing stores. Of all the other power banks I've tried this one is the best.

It arrived on time and in great shape. The thing is a beast that can keep my cell phone and other USB rechargeable devices running for a week or more. Excellent for longer term hiking and canoe trips. Anker really does these power bricks well. I have three of them, in various sizes and weights, so I can fine tune the weight to power needs-especially important on backpacking trips. The dual charging capability is sweet too, cutting the recharge time down dramatically.

Very happy with this purchase! I have taken this Anker PowerCore on two vacations so far. It can charge an iPhone from 0%-100% 8+ times before it needs to be recharged. There are 3 USB ports so you can charge multiple electronics at once, definitely a plus! Great for people who frequently need to charge on the go. Cons- it is bulky/heavy to pack & takes a while to charge.

It is bigger then i expected it to be but it works out great it does take a while to charge but that's why there is a dual charging system to it. When fully charge it last 4 days I use it every day and when my phone is at 15% it brings it up to 100% very reliable.

Love the fact that you can plug in two chargers to it at the same time to charge faster. DON'T make the mistake of using a single charger with two plugs. I almost burned one up doing that! Use two separate chargers! I can get several charges of my iPhone 8 and my older iPad before needing to recharge the power pack.

I fully charged this and am very glad I purchased it. It has delivered on all the features. I have rechargable hearing aids on top of the usual phone and tablets so this gives me security knowing I have a way to charge from a portable source for all my needs.

The power bank is very big, I thought it would be smaller... I love it tho ..takes a while to charge but once it's full; it takes long to die...love it and I am happy with the purchase.

You cannot beat these portable battery packs they actually charge your phone substantially faster than just pulling it into the wall outlet but the downside is it takes that much longer to recharge them also the bag comes with this excellent for a curing the additional accessories for your power adapter in your cord but like I said you cannot beat these battery packs for traveling

Solid built product and great design. I will have to return it since it only work for charging my iPhone but not my Macbook Pro, nor my Sony A7iii camera. It comes with only USB port but not any type-c. If you need to charge your laptop, you will need to get an updated power bank with power delivery protocol (PD power bank), which is normally twice as much as this one on price.

When I bought this portable charger I never would have thought it was built so well. Now that I have it I am very pleased. Anker has good quality products and they are my new source for anything I need for my phone. I highly recommend their line of accessories.
