Anker 737 Power Bank (140W, 24,000mAh)
Best for: Laptop and multi-device users who need massive capacity with 140W fast charging
Rated 9.1/10 by our testing team
The Anker 737 is the power bank for laptop users. 140W Power Delivery 3.1 charges a MacBook Pro at full speed — something most power banks can't do. 24,000mAh capacity provides 1.3 full MacBook Air charges or 4+ iPhone charges. The smart OLED display shows real-time wattage, estimated time to charge/discharge, and lifetime charging stats. Three ports (2x USB-C + 1x USB-A) charge all your devices simultaneously.
Why we like it
- 140W PD 3.1 — charges laptops at full speed
- 24,000mAh — 4+ iPhone charges
- Smart OLED display shows real-time stats
Flaws
- Heavy at 1.3 lbs — not pocketable
- Not TSA-approved for checked bags (>100Wh)
- $109 MSRP — premium pricing

Anker Power Bank 20,000mAh with Built-in USB-C Cable
Best for: Travelers and commuters who want high capacity without carrying a separate cable

This is the most convenient Anker power bank. The built-in USB-C cable means you never forget your charging cable. 87W max output charges laptops and phones. 20,000mAh gives you 4+ iPhone charges.

Why we like it
- Built-in USB-C cable — never forget a cable
- 87W output handles laptops
- 20,000mAh — 4+ iPhone charges
Flaws
