Safety: Power banks contain lithium-ion cells. Use the cables the manufacturer supplies or recommends, keep the unit away from heat, and follow the manual.
The Anker Prime 26,250mAh 300W Power Bank lists a 300W total output across two USB-C ports and one USB-A port, plus a 99.75Wh rating and a 240W USB-C cable in the box.
This review is based on the manufacturer listing and specifications. It is aimed at buyers with one or two laptops who want a single bank for everything. See more options in our Laptop Power Banks category.
Our Verdict
The standout feature of the Anker Prime 26,250mAh 300W Power Bank is the 300W total output, which the manufacturer says is enough to keep two MacBook Pros running at full speed. The listing also gives a 250W dual USB-C input for recharging and app control for adjusting output.
The trade-off is size and weight for the output, at 1.32 pounds, and the fact that most users will not need this much power. It suits someone who charges two laptops or a laptop and several accessories; a single-laptop traveler can use a smaller bank.

Capacity and Output
The listing gives 26,250mAh and a 99.75Wh rating. It lists 300W as the maximum across three ports and up to 140W for fast laptop charging on a single port when used with a 5A cable.
The high total is meant for charging more than one demanding device at once. The listing does not break down the per-port split, so check the product page if you plan to run two laptops together.
Charging and Setup
The bank accepts a 250W dual USB-C input according to the listing, which is aimed at short turnaround between uses. You need a charger that can supply that power to reach it, and the listing does not include one.
A 3.3 ft USB-C cable rated for 240W, a travel pouch and a welcome guide are in the box. The smart display and app show charging information and allow manual adjustment of output power.
Build, Size and Portability
The listed dimensions are 6.3 x 2.5 x 1.5 inches and the weight is 1.32 pounds, which is a typical size for a bank of this capacity. The 1.5 inch thickness is modest, so it fits in most laptop bags.
Anker describes the capacity as TSA-approved. Airlines set limits by watt-hour rating, so confirm the 99.75Wh figure on the unit against your airline policy. The listing gives a 24-month warranty.
Features and Compatibility
The listing names MacBook Pro as a laptop example. It does not list every compatible laptop, so check your charger wattage against the 140W single-port figure.
App control adds the ability to adjust output, but it also adds a step to setup. Treat it as optional if you just want to plug in and charge.

Final Verdict
The Anker Prime 26,250mAh 300W Power Bank is built for heavy use, with 300W total, 140W fast charging and a 240W cable. Its compromise is weight and an output level that many users will not use. It fits buyers who charge several demanding devices; most single-laptop users should choose a smaller bank. Check the product page for details the listing leaves out.
