Anker 737 Power Bank (24,000mAh) vs Baseus 65W Power Bank (20,000mAh)

The Anker 737 can deliver 140W through a single USB-C port, which means it can charge a MacBook Pro 16" at the same speed as a wall charger. For travelers who carry power-hungry laptops—creative professionals with MacBook Pros, engineers with high-performance Windows machines—this is a genuine advantage. You can top up your laptop during a layover at nearly full charging speed.

The Baseus 65W maxes out at 65W, which is still enough to charge most 13-15" laptops at full speed. A MacBook Air, Dell XPS 13, or ThinkPad X1 Carbon will charge just as fast on the Baseus as they would on a wall outlet. The 65W limitation only becomes a bottleneck with larger, power-hungry machines that draw 80W or more.

The Anker 737's 24,000mAh capacity gives it roughly 20% more juice than the Baseus 20,000mAh. In practical terms, that translates to about one extra full phone charge or an additional 15-20% on a laptop. For multi-day trips without reliable power access—think long train journeys, camping excursions, or back-to-back layovers—the extra capacity provides meaningful peace of mind.

However, for most single-day travel scenarios, 20,000mAh is more than sufficient. The Baseus can fully charge an iPhone 15 about 4 times or add 50-60% to a MacBook Air. Unless you regularly find yourself away from outlets for more than 24 hours, the capacity difference rarely matters in practice.

Weight matters when you are carrying a power bank every day, and the Baseus wins here at 1.05 lbs versus the Anker 737's 1.36 lbs. That third-of-a-pound difference is noticeable in a daypack or jacket pocket. The Baseus is also slightly more compact, sliding more easily into travel organizers and tech pouches.

Both power banks are airline-approved—the Anker at 86.4Wh and the Baseus at 74Wh, both well under the 100Wh FAA limit. Neither will cause issues at security. For one-bag travelers and minimalists who count every ounce, the Baseus offers a meaningfully lighter carry without sacrificing the core laptop-charging capability.

At roughly $46 versus $110, the Baseus 65W costs less than half the price of the Anker 737. For most travelers, this is the deciding factor. The Baseus delivers 65W laptop charging, 20,000mAh capacity, and airline-approved portability—all the features that matter for travel—at a price point that does not require deliberation.

The Anker 737 is objectively a better power bank with more capacity, more power, and a smarter display. But the question for travelers is whether those extras are worth an additional $60-65. For the 80% of travelers carrying standard ultrabooks and smartphones, the Baseus covers every charging scenario they will encounter on the road.
