Anker 737 Power Bank Review: Ultimate Portable Power for Remote Work
✅ Pros
- Massive 24,000mAh capacity (charges a MacBook 1.5x)
- 140W bidirectional USB-C charging (fastest in its class)
- Smart digital display shows remaining capacity and charge speed
- Can charge laptop + phone + AirPods simultaneously
- Airline-safe (under 100Wh) for carry-on travel

Key Takeaways
- The Anker 737 delivers 140W bidirectional charging — enough to fast-charge a MacBook Pro
- At 24,000mAh, it can charge a laptop 1.5x and phone 4x before needing a recharge
- The smart display shows exactly how much power you're drawing and how long until empty
As a digital nomad who works from coffee shops, co-working spaces, and occasionally parks, reliable portable power is non-negotiable. The Anker 737 (PowerCore 24K) has been my go-to for six months of travel across Europe and Asia.
Capacity That Actually Matters
24,000mAh sounds like a lot, and it is. In real-world testing: it charged my MacBook Pro 14" from 10% to 100% once, then my iPhone 15 Pro from 5% to 100% three times, with 20% remaining. That's a full work week of remote work without access to wall power.
Charging Speed
The 140W bidirectional USB-C port is the standout feature. It charges a MacBook Pro at full speed — the same speed as the Apple 140W charger. When recharging the power bank itself, it goes from 0 to 100% in about 1 hour 45 minutes with a 140W charger.
Smart Display
The small LED screen is more useful than I expected. It shows remaining capacity as a percentage, estimated run time at current draw, and input/output wattage. No more guessing whether your power bank is full enough for a trip.
Portability Trade-off
At 640g, this is not a pocket power bank. It lives in your backpack or laptop bag. But the trade-off is worth it for the capacity — I've never run out of power during a work day.
