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 20,100mAh 220W Power Bank lists 220W total output from two USB-C ports and one USB-A port in a compact body, with up to 140W for fast laptop charging on a 5A cable and a 240W cable in the box.
This review is based on the manufacturer listing and specifications. It suits people who want high output without carrying a larger bank. See more options in our Laptop Power Banks category.
Our Verdict
The strongest point of the Anker Prime 20,100mAh 220W Power Bank is how much output it lists for its size: 220W total, 140W for fast charging, and a body of 5.78 x 1.75 x 1.96 inches at 1.12 pounds. The 72.36Wh rating is below the 100Wh figure airlines commonly cite.
The trade-off is capacity: 20,100mAh will cover a laptop and a phone for a day but offers less reserve than a 26K model. It suits a commuter or traveler who wants a compact bank for a high-wattage laptop.

Capacity and Output
The listing gives 20,100mAh and 72.36Wh. Output is 220W in total across two USB-C ports and one USB-A port, with up to 140W for fast laptop charging when connected to a 5A cable.
The listing does not give the split between ports, so check the product page if you plan to charge a laptop and other devices together.
Charging and Setup
Recharging uses a USB-C input of up to 100W, so a charger rated near that level will refill the bank fastest. The listing does not include a charger.
The box holds a 3.3 ft USB-C cable rated for 240W, a travel pouch and a welcome guide. Use the supplied cable to reach the full output.
Build, Size and Portability
At 5.78 x 1.75 x 1.96 inches and 1.12 pounds, it is compact for the output it lists. The shape is closer to a thick brick than a flat sleeve, so check how it sits in your bag.
Anker describes the capacity as TSA-approved. Airlines set limits by watt-hour rating, so check the rating on the unit. The listing gives a 24-month warranty.
Features and Compatibility
The listing names a 16 inch MacBook Pro as an example of a laptop it can charge quickly, and describes video streaming on an iPhone 17 Pro Max as an example of phone use. It does not list every supported device.
Two-way charging means the same USB-C ports can accept power, which helps if you carry one charger and one bank.

Final Verdict
The Anker Prime 20,100mAh 220W Power Bank delivers 220W total and 140W fast charging in a compact body, with a 240W cable and a 24-month warranty. Its compromise is capacity.
