Customer Ratings & Reviews

It charges quickly, sleek. fits in my purse. Charges for hours.

We needed to buy a power bank for our son, who had a band trip to Disneyland, in order for him to be able to communicate with chaperones without the worry of a dead cell phone. This thing has been well worth the money spent. provides a couple of hours worth of a charge and is slim enough to slip into his pocket.

I needed a light and reliable power bank with the ability to fully charge a phone 5-6 times to use for a section hike on the Appalachian Trail. The one I used last year was a beast and about twice as heavy, which makes a difference when hiking up and down mountains with a heavy pack all day. So far so good on this one as I’ve just used it around the house so far.

Purchased this for a trip to Disney to make sure everyone in my family would have a backup charge throughout the day. This charger did not disappoint. Multiple full charges were very quick and without issue. Solid charger. A bit heavy but as expected for such a device. Highly recommend. Completely satisfied. Would buy again!

Faster charger , for your electronics , would purchase again .

This charger works great! It takes a while to charge but once it charges it last a while. I use it for the weekends and its able to charge my phone multiple times. Pretty fast charge. It is heavy but I don't mind since it stays in my backpack.

Bought these for my teen boys. They LOVE them. They told me they have like a 96 hour charge life. My one son was playing some game while charging his phone and it continued to increase his charge even though he was playing - our other chargers don't do that. They are EXTREMELY happy with this purchase.

Worked as advertised. A little heavy but it charges phones faster than standard wall chargers only wish it had a usb-c port out.

great power core last a long time fast charging easy to use

This is an amazing portable charger! It goes and goes. Will charge up an iPhone 0 to 100 in less than an hour over and over before it needs recharging. Great texture, doesn’t take up much space so it’s easily portable; and it has battery indicator lights on the front to let you know how much charge it has left. Highly, highly recommend!!!

Anker is a reliable brand for power banks. I trust Anker more than any other brands. The PowerCore Metro 20,000 mAh is great for traveling. It does not take very long to charge. It is handy and stylish. In comparison to my other Anker power banks, this one is lighter and slimmer. However, it is wide. It also does not come with a dust bag/sleeve.

The only downside is that it takes a long time to charge. This charger works great for someone who is always on the go. Normally I never have time to charge my phone during the day and this really helps keep it charged up. If your iPhone is dead or close to, it will get it up to about 30% really fast. Highly recommend.

bought this for my boyfriend and he loves it. he uses it everywhere and gets lots of compliments on how little and sleek it is! he has used it many times and has yet to charge it. one thing though, we cant figure out what some if the light colors mean but overall great product.

This is a neat and powerful external battery, and it charges phones pretty fast. Two provisos and one real shortcoming. 1) It’s heavy (accurately described in Specifications) which makes toting it around a bit of a drag. 2) The charging cord that comes with it is really short. 3) The “instructions” are pathetic and there’s evidently nothing online. Not the least that they’re written in micro-font. I know it’s simple to operate but there’s improvement to be made. Hence 4 instead of 5 stars.

Purchased for our granddaughter, she has told us how much she likes it at least three times. Easy to carry, reliable. She commented that it charges her phone much faster than her previous portable charger. So, we are pleased, and should we ever feel a need to have one for ourselves, this is the one we will get.

My largest issue with portable chargers is that they themselves don't remain charged. Took this on a weeklong trip as a backup if my phone or laptop died. It remained charged the entire time and charged my phone quickly. It is a little heavy to carry in your purse though. It has two different ports which was perfect.

Nice size. Accommodates more than 1 unit. Compact.

Love this thing! I have taken three trips with this charger already and the battery hasn’t needed much charging. I can charge two phones pretty fast! It’s amazing! Although charging this charger itself to 100% may take an hour or a little longer, it is well worth the purchase!

I received 2 Anker chargers in plenty of time for Christmas and gave them to my sons. It charged fully in several hours and when needed it charged my son's phone fully in a half hour. I already got one as a gift and was very pleased. Last year our power went out for 2 days and it would have saved the day.

Bought this for a camping trip. It’s a bit heavy, but that’s ok. It lasts sooooooo long. I had it with me for 4 days. Charged my phone countless time, and it barely out a dent in the battery percentage. I also love the knit quality texture and the mesh pouch that came with it.
