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.
