Anker Prime 26K 300W Puts Two Fast Laptop Charges on One Carry-On Battery

Anker Prime 26K 300W, priced at $179.98 (was $230), arrives at a useful moment. New iPhones (18 Pro, 18 Pro Max, Duo, etc.) want faster wired charging, and plenty of laptops still expect a wall brick that can push 100W or more. This pack tries to cover both without forcing you to haul a second charger.

Model A110A has a battery capacity of 26,250mAh, or 99.75Wh, which falls short of the 100Wh limit for airline carry-on size, but is still close (yet fully legal). The dimensions are 6.3 by 2.5 by 1.5 inches, with a weight of around 1.32 pounds (600 grams). To be honest, this pack is more suitable for a backpack than a jeans pocket. The two USB-C ports can deliver 140W each using USB Power Delivery 3.1. Yes, that includes a 28V 5A step, which high-wattage laptops actually use, as well as a USB-A port capable of 22.5W (or 20W if all three ports are in operation at the same time), for a total of 300W. Although 300W is the maximum you’d receive if everything was maxed out at the same time, in fact you can easily run two hungry laptops at 140W each as the phone drink away at port A.

Anker’s lab results reveal that an M4 Pro MacBook Pro can reach 50% in 27 minutes, while an iPhone 16 Pro does so in 26 minutes. Independent tests confirm this, with an iPhone 17 Pro Max going from 1 to 50% in just 22 minutes, leaving just enough energy for about three full phone charges. Ever notice how some computers aren’t fully charged? A 14-inch MacBook Pro reached 100% battery life and still had some power remaining. What’s preventing the rest? An M16 has a fairly conventional stop of 70-80%, but the conversion heat consumes a portion of the stored energy.

The second half of the story is recharging speed, with each USB-C capable of taking up to 140W. Both of those C ports can handle up to 250W if you use 5A cables, ideally in conjunction with two powerful wall chargers. Anker claims to be able to achieve 40% in 10 minutes and 50% in 13 minutes. Testers who used dual input reported a complete refill in 48 minutes to slightly more than an hour, depending on the wall chargers. You can also pass-through charging, which allows you to charge your phone(s) while the pack charges itself. The box contents, however, are rather basic: a 3.3 foot 240W cable, a travel pouch, and a simple tutorial to get you started.

The front of the pack has a color screen that rotates with the pack (so you don’t have to twist it back and forth in your hand to check on it), which displays the remaining percentage, power on each port, power input, and battery temperature. Anker also offers a phone app with additional capabilities such as volt, amp, and watt graphs, as well as firmware upgrades and smart allocation modes that lock power to a single port. PowerIQ 4.0 does its best to decide how to distribute energy across numerous devices, and ActiveShield 4.0 is quite concerned about temperature; tests rarely saw the pack get beyond 41°C in a typical room, though a lengthy 140W session will still warm the shell. Just a quick remark on the display side: due to its gloss finish, it is a bit of a fingerprint magnet, and there is no built-in cord, wireless pad, or speaker to help you find a lost pack.
