Baseus Blade 100W vs Anker 737

The Baseus Blade and Anker 737 represent a genuine trade-off in portable power: one prioritizes compact size and multi-port flexibility, the other prioritizes raw capacity and peak charging speed. Both are airline-legal, both carry enough charge for a full laptop charge-and-a-half on a travel day, and both support 100W single-device laptop output — but the differences between them are significant enough to matter.

Weight and footprint are where the Baseus Blade earns its audience. At 1.0 lb (450 g), it is 330 g lighter than the Anker 737 at 1.72 lbs (780 g). That gap is not negligible over a long day in a shoulder bag or on a hiking approach to a remote worksite. The Blade's flat, slim shape also stacks cleanly against a laptop in a bag without creating awkward bulk. For travelers already carrying a laptop, charger, and accessories, reducing the power bank's contribution to pack weight by a third is a meaningful benefit.

The Anker 737 counters with capacity. Its 24,000 mAh (88.8 Wh) holds roughly 20% more energy than the Blade's 20,000 mAh (74 Wh). On a longer travel day — a red-eye flight, a multi-day camping trip, or a full conference day away from outlets — that additional 14 Wh translates to roughly one extra phone charge or a meaningful extension of a laptop charge session. The 88.8 Wh rating also sits comfortably within the 100 Wh airline carry-on threshold, while the Blade at 74 Wh is even more conservatively within limits.

Peak output is the Anker 737's second structural advantage. At 140W, the Anker 737 covers the maximum USB-C input of virtually every laptop currently on the market, including MacBook Pro 16" (96W–140W rated), high-performance Windows laptops, and gaming-class machines. The Baseus Blade's 100W ceiling charges these same machines — just not at their maximum supported speed. For most users, that speed difference is minor and unnoticeable in practice. For users who specifically bought a 140W-capable charger to maximize their laptop's charge rate, matching that with a 140W power bank is the logical pairing.

Port configuration tips toward the Baseus Blade for users with older accessories. Two USB-A ports (30W each) allow two USB-A devices to charge simultaneously — a game controller, an older phone, a headset — without adapters. The Anker 737 provides one USB-A port, which handles one USB-A device at a time. Both banks share identical 65W max input, meaning neither charges faster from a wall than the other. Choose the Baseus Blade if weight, size, and USB-A flexibility are the priority; choose the Anker 737 if you need the highest capacity, fastest peak output, and can accept the added weight.
