If you’re frequently on the move with a high-performance laptop, the Anker 737 Power Bank is a game-changer. With an impressive 140W charging capacity, this power bank is my top pick for keeping devices powered during long trips.
Why Choose the Anker 737?
Finding a portable charger that delivers enough power for high-wattage laptops is rare, but the Anker 737 stands out. With 140W USB-C output, it’s one of the best options for MacBook Pros, gaming laptops, and other power-hungry devices. Plus, the built-in display showing real-time charging stats makes it both practical and futuristic.
Design & Build Quality
The Anker 737 feels premium from the moment you pick it up. Its compact, square design (15.7 × 5.5 × 5 cm) fits nicely into bottle holders and backpacks, though it might be a tight squeeze for slim laptop bags. Weighing 630 grams, it’s heavier than some alternatives—but the trade-off is worth it for the performance it delivers.
The standout feature is its vivid color display, which provides real-time data on battery percentage, charging speed, and power output for each port. It even offers a low-current mode for smaller devices like earbuds, activated with a double press of the power button.
Performance & Charging Speed
With three ports—two USB-C and one USB-A—the Anker 737 is versatile enough to charge everything from laptops to smartphones simultaneously.
| Port | Max Output | Use Case |
|---|---|---|
| USB-C 1 | 140W | Laptops & tablets |
| USB-C 2 | 100W | Phones & smaller laptops |
| USB-A | 18W | Accessories |
It supports fast charging protocols like PPS, PD 3.1, and Samsung Super Fast Charging, making it compatible with a wide range of devices. In testing, the Anker 737 consistently delivered up to 140W without voltage drops, even under heavy loads.
Battery Capacity & Efficiency
With a 24,000 mAh (86.4 Wh) battery, the Anker 737 can charge:
- MacBook Pro (16-inch): 1.3 times
- iPhone 15 Pro: 4-5 times
- Samsung Galaxy S23: 4 times
Efficiency is excellent across different power levels:
- 100W charging: 89% efficiency

- Phone fast charging: 87% efficiency
It recharges itself at 140W in under an hour, which is one of the fastest recharge rates in the market.
Travel-Friendly Features
Despite its high capacity, the Anker 737 is flight-safe, making it perfect for long-haul flights. However, it doesn’t support UPS mode or pass-through charging while recharging, which may be a downside for some users.
Price & Value
The Anker 737 is a premium product with a premium price tag—around $149 / £140 / AU$190. However, frequent discounts (up to 30% off) make it a solid deal if you catch it on sale.
