One of our strongest picks is the Baseus 20000mAh 65W Laptop Power Bank, a standout in our Best Power Banks for Laptops 2026 list. The Anker PowerCore 20100mAh Power Bank is another excellent choice.
How do I choose the right power banks?

What should I look for when buying power banks?
10,000 mAh suits phones; larger banks suit laptops.
Is the Anker 737 worth the premium over the Baseus 65W?
For MacBook Pro 14/16 users, gaming laptop users, or anyone who needs maximum output: yes. The 140W vs 65W difference is substantial for high-wattage laptops. For MacBook Air and thin Windows ultrabook users, the Baseus delivers effectively identical results at a lower price and smaller size.
Which is better for airplane travel?
Both are airline compliant (under 100 Wh). The Baseus at 72 Wh has more headroom. The Anker 737 at 86.4 Wh is closer to the 100 Wh limit, still compliant, but verify before each trip as policies occasionally change.
Which has better real capacity?
The Anker 737 delivers approximately 87% of rated capacity; the Baseus delivers approximately 84%. The Anker has both more rated capacity (86.4 Wh vs 72 Wh) and slightly better efficiency, giving it meaningfully more real-world deliverable energy.
Can the Baseus 65W charge a MacBook Pro?
Yes, but slowly for the 14-inch and very slowly for the 16-inch. The 14-inch MacBook Pro needs 67W for full-speed charging, the Baseus outputs 65W, close but not quite full speed. The 16-inch needs 96W, the Baseus charges it very slowly. The Anker 737 at 140W charges both at full rated speed.
Will the Baseus 65W charge a MacBook Pro?
It will charge a MacBook Pro, but slowly on the 14 and 16 inch models. The 14-inch MacBook Pro requires 67W for normal charging. At 65W input, the laptop charges at slightly below full speed. The 16-inch MacBook Pro requires 96W, the Baseus will charge it very slowly or maintain battery while in light use. For MacBook Pro 14/16, the Anker 737 at 140W is the better choice.
