**The Anker 737 Power Bank is the one accessory that should be in every tech lover's bag.** With 24,000mAh of capacity and 140W of USB-C Power Delivery, it can charge virtually anything you own — including laptops. Here's our full review.
Who Is This For?
Digital nomads, frequent travellers, and anyone who's ever panicked at 10% battery with no plug in sight.
Capacity: Genuinely Massive
At 24,000mAh (87Wh), this power bank can fully charge a MacBook Air M4 roughly 1.5 times, an iPhone 17 Pro about 4.5 times, or a Nintendo Switch OLED around 5 times. It's enough to keep you going for days away from a wall socket.
140W Output: Laptop Charging, No Compromises
The headline feature is 140W USB-C Power Delivery. That's enough to fast-charge a MacBook Pro at full speed, something most power banks can't touch. In testing, we charged a MacBook Air M4 from 20% to 80% in under an hour. The smart display shows real-time wattage, which is both useful and oddly satisfying to watch.
Build and Portability
At 620g, it's not light — but for this capacity, it's remarkably compact. It slides into a jacket pocket or laptop bag sleeve without issue. The matte black aluminium shell feels premium and resists scratches well.
Airline Safe
At 87Wh, it's under the 100Wh airline limit, so you can carry it in hand luggage on flights. That's a huge advantage for travellers.
The Catch
You'll need your own 140W PD wall charger to recharge it at full speed. Anker doesn't include one in the box, which feels like a miss at this price point.

- Premium price compared to lower-capacity banks
❓ Frequently Asked Questions
Absolutely. With its current price point and feature set, it remains one of the best options in its category.
While newer models exist, the Anker 737 Power Bank (PowerCore 24K) still holds its own thanks to excellent build quality and software support.
