Customer Ratings & Reviews

Its on the expensive side but its so worth it! This is the nicest power bank I’ve ever had (and the most powerful)! You can charge anything you want with this thing at full speed and still have some power left over after it’s done. The screen and Bluetooth are nice things to have to let you see the charging speed and change settings like brightness and see how many times you can charge your own devices (you can customize it on the app). I mainly use it for the ROG Ally, which it’s more than capable of powering and over doubling the battery life. And on top of the Ally I can charge other thing like an iPad or my iPhone at max speed at the same time as well. I would also really recommend pairing it with the Anker prime 100W charger (or equivalent) as well (shown in the photos next the the power bank) to keep the power bank (it can suck up lots of power and charge fast at 170W with two cords) and everything you have charged anywhere! Small things to note each USB-C port is capable of doing 140W max if you want the 250W you’ll need to use more than one port. Also, this thing is very large and heavy so be prepared for that. Another thing, only this 250W power bank has Bluetooth. The other smaller versions of this does not have it. And finally you do not need the app to use this power bank and also the app does not require you to make an Anker account to use it. I know this is long and a mess but hopefully it will answer some questions!

I don’t know why this isn’t rated higher. I mean okay, you don’t really NEED this, let’s be honest, but it’s sooo nice to have. This thing charges in less than an hour, LESS THAN AN HOUR for 27000 mAh!! And you can plug in two different charging inputs to make it charge with a max of 140 W which is crazy, and the fact that it can charge and be charged from the same ports. I can charge my Macbook Pro anywhere with a faster speed than the charger it comes with, plus I can charge my phone and other things as the same time without lowering other speeds. The display looks awesome, the build quality is immaculate, (though the button could have been better), and the design is just so sleek and nice. You can probably get a much cheaper portable battery that functionally performs similarly, but is it going to be as cool as this one? No. So if you got the money go for it! You won’t be disappointed, but just know you will be paying a premium for the coolness and display, and extra functionality like a charging pad that anker also sells for this to sit on, which is great.

I had no issues keeping my gaming laptop charged on a 2 hour flight from FL to OH. By the time I landed, it was just about 10%, and it managed to keep the laptop at a full charge. I carry it with me to work, charge it there, and then charge my phone while at home to save on energy. Lasts me through the day and night. Great buy.

Very good power supply. I had one already and bought this one for my grandson. He really likes it and uses it all the time. Small and powerful, charges fast and charges devices fast.

I love this thing—no worries about dead devices. There is lots of flexibility with connections. The display gives a lot of valuable information and I love a solid app to add features. I also purchased a dock and love its little clock display while on it.

Got to use with my ROG Ally, and does the job. Also bought charging base whick best buy don't have at the time. Like it too. Just set on top and charges. The screen is nice letting me know how much charde and estimated time usage too

Purchased this 03/12/24 after about a year of waiting. I wanted to wait until there was a sale or newer model to release prior to buying this one, but it has not happened and it’s held its value all this time. As a bestbuy member, I got $30 off leaving this at $150 pretax, which is a steal for its function. Can charge a silicon 16 inch mac to fulll capacity in under an hour, can charge itself with two high capacity usbc charging inputs for a combined 250w in less than an hour.. it’s really great. I take it in my backpack everywhere. Smallest size allowed on a plane.

Charter holds up pretty good. Charges multiple devices pretty fast at once. Wold recommend for in home/ office use. A bit heavy to carry around.

Very good very well too use on long trips I would recommend 100%

Saves the day when traveling with a family multiple charges on all our devices. Charged two iPhone 16s and iPad Pro had some to spare for MacBook Pro.

I got this product on sale and used my best buy points to snatch this deal, and it was worth every penny. It's very fast in terms of charging my phone. Very happy with my product.

So far this battery has helped me when I’m traveling and am on the road. The digital screen was helpful to see the charge output as well as the charge input. I purchased a Anker GAN 150W charger and it does a great job of replenishing power to this unit. It comes with a cable and bag.

Greates battery bank for my ROG Ally gives a additional 3hrs of play on 30w and keeps the battery maxed. Must have for AAA gaming on the go 10 outta 10 CAN RECOMMEND ^_^

VERY VERYYY VERYYYY MUST BUY, KEEPS ALL MY ELECTRONICS CHARGED AN IT CHARGES FAST AS HELL BOY!!!!! MUST BUY!!! 5 STAR FOR SURE FOR SURE!!!!

This is the largest capacity allowed for carryon while flying. This power bank really packs a punch! With 250w out it easily charges my macbook pro m3 max 16” at 140w from 0% to 80%+ in around 40 minutes. I can recharge the power bank with my macbook pro 140w charger and it easily accepts the entire 140w and is done within 40 minutes. The power bank has options for it to recharge slower during certain hours which helps the lithium batteries maintain a longer life. There is also an option for it to charge devices slower as well. Overall this is a great power bank. For the price I do wish it would have came with a carrying case as there are only a couple of 3rd party companies that make them for this odd shape/size. There is an addon charging dock for this power bank, but its quite expensive and I do not own it.

Absolutely love it. My power went out recently and my phone died so I was stuck without my phone. Not anymore:)

A bit bulky but other than that absolutely amazing power bank

It’s a nice and helpful item. I like my purchase and the price.

This Anker charger is amazing! It charges my phone super fast and holds a great amount of power. The digital screen is a nice touch and the design feels premium. I carry it every day and it’s never let me down. Totally recommended!

The Anker Prime 27,650mAh Power Bank is an absolute lifesaver for long-distance travel! I used it on a recent trip, and it kept all my devices charged up without any issues. The capacity is huge—I didn’t even have to worry about running out of juice, even after multiple charges. It’s compact enough to fit in my bag, and the fast charging is a big plus. If you travel a lot or just need reliable backup power, this power bank is a must-have. Five stars for sure!
