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.

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.

I purchased the Anker Power Bank from Best Buy, and it performs exactly as needed for both medical and everyday devices. It powers my medical cooler all day, keeping my medication consistently cool. For phones and tablets, it provides a reasonable number of charges: about two full charges for my iPhone 17 Pro Max and multiple charges for my iPad M4 Pro. High-demand devices naturally draw more power, so it’s best for a few charges or a big boost to get through the day until you can recharge again. While it has limits with heavy-use devices, it’s reliable and efficient—especially for medical needs.
