Customer Ratings & Reviews

Very good purchase, it works very well, I use that every day

Very easy to use and good with charging large and small devices.

This Anker 20,000mAh power bank is excellent. It has enough capacity to fully charge my phone multiple times, and the30W fast charging is a huge plus. Charging is quick and efficient, whether I am using it for my phone, or other devices. The build quality feels solid and durable, and it is still easy to carry despite the high capacity.

Stopped working suddenly not satisfied at all with this

its compact and great battery capacity. its light and its fast.

I’ve been using the Anker power bank for a while now, and it’s honestly one of the best purchase I’ve made. Super reliable, fast charging, and holds a charge enough days Perfect for travel or just everyday peace of mind when you’re out and about!

I’ve been using the Anker battery pack for a few weeks now, and it’s honestly exceeded expectations. The build quality feels super solid and durable—like it can handle being tossed in a bag without worry. It charges my phone lightning fast, and I’ve been able to get multiple full charges off a single pack. One of my favorite features is the LED power indicator. It’s clear, accurate, and helps me plan ahead. It’s a little heavy, but tahts to be expected with how much capacity it holds. Whether I’m out hiking, traveling, or just stuck in long workdays, this thing keeps me going without reaching for a wall outlet. Definitely a 5-star product. If you're on the fence, just go for it. You won't regret it.

It’s amazing, small and very compact, slip into my pocket for work amazing, long lasting battery too, very durable I’ve dropped it off from 2 story’s and still works great, fast charging gotta need that too,would recommend this product

Fantastic charger. The display is helpful and it holds a charge well. The charging cord attached as a lanyard is a nice touch, however the cord will come out.

Very nice battery pack for the price! Doesn’t take that long to charge a mobile phone down at 15 percent and still has a lot of power left over to fully charge other devices!!

Great power bank, charges my iPhone 16 pro max to 80% in about 20 mins. And still has plenty of charge left for around another 6 charges of the same iPhone.

I bought this charging block because I could not find my old one for the life of me. Once I initially charged the block, I was able to fully charge my phone, my mom’s phone, and her iPad. There was still 16% left after three (pretty close to) full charges! My mom ended up buying one for herself, and I bought one for my dad as a Christmas present.

Gives me about 4-5 full charges and has been a lifesaver. It has really fast charging and it also charges pretty quickly. I love the 2 options it has. One is regular charging and the other one is fast charging. I also appreciate that it shows percentage rather than bars since it makes it easier to see how much I have left.

This product has been helping me a lot during my trips, i can charge my phone around 4 times and still charge my switch 2. The digital screen that tells me battery percentage is also very helpful

Going mostly by Anker reputation, but so far it's good. Seems to take a long time to recharge but I got 3 phone and 1 watch charges from it with 20% left. Be advised, the 30 watt rating is for devices other than 5 vdc which is what most phones use - for 5vdc the max is 3 amp which is 15 watts and it is not higher when charging multiple devices (2 devices get 7.5w each). The strap is a usb c to usb c cable which is neat

This charges my phones multiple times before it needs to be recharged. It charges very quickly and is super easy to use.

I’ve been super impressed with the Anker 20,000mAh 30W Power Bank! It’s been a lifesaver on long days when I’m away from outlets—it charges my phone multiple times, and I love the fast 30W speed that quickly powers up everything from my phone to my tablet. It’s a bit on the heavier side, but the extra power is totally worth it. The build feels really solid, too, so I’m confident it’ll last. If you need reliable, fast charging on the go, this is it!

I bought this for a trip to Europe so I could charge 2 phones without worrying about different power there. It charged overnight. From that charge, I could charge my phone 4 times. The digital display shows the percentage of charge left in the bank. The USB-C cord is right in the lanyard so I didn't have to carry another.

Excellent product! The way the cable is also a holder fot hw battery and the way if charges!! Amazing!. And also 2 phones at once.! Great best anker battery there is.

An amazing portable charger! Charges quite fast without using up too much of the powerbank’s battery. The only issues I have with this specific Anker model is the weight, it is a little hefty and big to haul around in a pocket or hand. Other than that, a very good powerbank! Have reccommended to others who are looking for a very low effort/minimal care powerbank that’s still reliable. I also find the wire convenient, it acts as a bracelet and is used as a wire as well.
