Anker - Prime Power Bank, 26,250mAh 3-Port Portable Charger with 300W Max Output, Two-Way Charging

The Anker Prime 26,250 mAh Power Bank (300W, A110A) is a high-capacity power bank that I purchased to rapidly charge my iPhone and Alienware gaming laptop. When I plugged it into my Alienware, I received a message on my laptop screen saying that it was "undersized," etc. However, that battery charged quickly. It was also able to boot up my Alienware Laptop. I can't wait to try the dual-charging feature, but I need to purchase a second USB-C cable first. I love the sleek design of this power bank and appreciate the seemingly solid construction. This power bank works with Anker's phone application, which gives you detailed information about the rate of power being delivered to the devices you are charging. The app also allows you to change some settings. I wish the app would tell me how long it will take to charge my devices. I waited until this item was for sale at ~ $172.

Never had a battery like this. It’s fast, easy to use and I love having it laying around to charge cameras, phones and lights. My college age daughter loves it too. I should have bought two of them. It’s quiet, it hasn’t got hot and the cord that comes with it is top quality.

It puts out 100s continuously without overheating (unlike their power bricks) But the % meter still continues to lie… it will accept a charge and tell you it is at 100.0%. Unless you need the extreme power capacity, the older brick style power banks definiteky do the job. The recharge can be super fast, but not always. It has to be in the mood. Buy it on sale, and its a 4 star.

This power bank has become my go-to for travel and long days out. The 26,250mAh capacity is genuinely huge — I can fully charge my phone multiple times and still have juice left for a tablet or laptop. The 300W max output is no joke; it charged my laptop noticeably faster than I expected from a portable charger. The three ports mean I can charge my phone, earbuds, and a friend's device all at once without any of them slowing down. Two-way charging is a nice touch too — I can top up the power bank itself quickly when I get near an outlet. Build quality feels solid and it's not as bulky as I feared given the capacity. The display showing remaining charge is a small but useful detail. Only minor downside is the weight, but that's expected for something with this much capacity. Overall, excellent value and reliability. I dislike that I can't both charge (and discharge) simultaneously. You are either charging or discharging.

I've grown to like this charger better than my 27650, 250W power bank. The display is clear display while showing the remaining battery level. I also like the smaller form factor makin it easier to travel with. A clear advantage. What really stands out is the capacity and how well it extends my laptop’s battery life—especially during my flights to Atlanta, Pittsburgh and North Carolina. The build quality is excellent, with a solid, premium feel. Between the sleek design, sturdy construction, and strong performance, it’s easy to see why I like it so much.
