Customer Ratings & Reviews

Good product, still my option. Best Buy ever, the excelent quality and working for long 12 mounths and i bought again right know.

Its very helpful and it charges fast the battery last couple days .

Great for on the go charging for my phone. Can be used for other devices as well. It doesn't store as much power as other previous Anker battery banks that I have but it's still good to use, especially if you are on the go and can charger my phone multiple times to full after extended use of my phone throughout the day. Takes about 2-3 hours to recharge if it's completely depleted. Recommend to those who need a lightweight battery bank to carry on the go.

Great battery. Nice flat shape. Holds a lot of power

Excellent for use on my new iPad and I can even charge my vape with it. Holds a charge for several uses.

fast charging you can take it anywhere with long hours recharging.

Excellent battery pack, easy to travel with and charges quickly.

I never had a power bank before, but this is really helpful. a little bit heavy but worth it.

Easy to use. Meet expectation - super charge my phone. Good deal.

Lots of power. PD capability fast charges both my Apple Watch Ultra and my iPhone 14 Pro max. Sadly it can’t charge other devices while the power bank is charging itself.

I bought this after my previous battery pack decided to fail on me during a weeklong bicycle tour. I needed something that I could charge once and get multiple charges for my cellular device. This power bank did not disappoint one bit. One full charge on this got 4 charges on my device. Couldnt be happier about this purchase.

It does what it is supposed to do. It provides extremely long working time to our camera. It really added that extra cushion one needs when visiting an all day attraction with the video running most of the time. You don't have to worry about the cam's battery draining because this lightweight very mobile power pack picks up the slack.

Working in the wildfires is a drag when it comes to power sources this portable battery kept my 16 shifts smooth with increased productivity a must have for any emergency disaster when it comes to mobile cells / light electronics also the warranty the product comes with it is a no brainer good money spent!

Charges relatively quick and charges my phone multiple times with 1 charge! I woild buy again any day

Excellent turbo charge for vacation. I got a dead phone charged up to 70 percent in 12 minutes.

needed extra portable for a trip, works perfect and fast

Very good battery, I have charged the device and threw it in my purse for those times you suddenly need to charge your phone. It has sat for 6 months in my purse and when I turned it on today, it still had a full battery.

Great charger! Last long! Charged phone fast! Compact!

Charges phones quickly. Is light and easy to carry around.

I have been looking for a reliable battery charger and the Anker PowerCore II is exactly that. I don’t have to worry about losing battery life on my iPhone when I travel.
