Our Review
The Anker 737 Power Bank, also known as the Anker PowerCore 24K, is a powerhouse companion for travelers who refuse to let a dead battery derail their journey. Packed with a 24,000mAh capacity, this compact brick delivers enough juice to charge a smartphone multiple times over or keep a laptop running through a long-haul flight delay. Its 140W max output, delivered through a combination of USB-C and USB-A ports, means it can simultaneously power up to three devices at once, making it ideal for travelers juggling phones, tablets, earbuds, and cameras on the go. The digital display on the front is a small but meaningful touch, showing exact battery percentage and estimated charging times so there's no guesswork when you're rushing to catch a connecting flight.
Built with the rigors of travel in mind, the Anker 737 balances serious performance with a design that doesn't punish you for carrying it. It's solid and substantial in the hand, yet still slips into a backpack side pocket or the seat pocket in front of you without becoming dead weight. The durable outer shell resists the everyday scuffs of being tossed into luggage, dropped on airport floors, or squeezed between other travel essentials. Anker's proprietary GaN-based charging technology inside allows this power bank to charge faster while running cooler, an important detail for anyone who's ever worried about a portable charger overheating in a hot car or direct sunlight on a beach vacation.
For the modern traveler who relies on multiple devices to navigate, document, and stay connected on the road, the Anker 737 Power Bank earns its keep as a genuine travel gear essential rather than just another accessory. It pairs well with USB-C laptops, supporting pass-through charging that lets you power your bank and your device from a single wall outlet in a cramped airport lounge. Frequent flyers will appreciate that its capacity sits within common airline carry-on regulations, so it can accompany you through TSA checkpoints without a second thought. Whether you're backpacking through unfamiliar cities, working remotely from a co-working space abroad, or simply trying to survive a long layover, this power bank is engineered to keep your gear alive exactly when you need it most.

What Travelers Say
This power bank saved me during a 14-hour flight delay. Charged my laptop and phone with plenty of juice left. The digital display is surprisingly useful for tracking usage.
Love the power output and multiple ports, but it's noticeably heavier than my old power bank. Still, for road trips it's worth the extra weight in my backpack.
Bought this specifically for charging my MacBook Pro on business trips. The 140W output is no joke—charges almost as fast as a wall outlet. Highly recommend for frequent flyers.
Works exactly as advertised and the build quality feels premium. Wish it came with the 140W charger included since you need it to unlock fast recharge speeds.
