When traveling, it’s easy to keep your devices topped off if you have easy access to a power outlet. Just plug in a power adapter and a USB cable, and you’re good to go. But what about those times when there’s no wall outlet in sight? That’s where a battery power bank can come in handy, and one of the best ones available is theAnker 737, which is currently just $76.99 at direct from the manufacturer after a coupon codeWS245UB5BF.
I have personal experience with the Anker 737, as I bought one on June 22, 2025 and have used it extensively. The power bank has a permanent spot in my travel bag for those times when I need to top off. The Anker 737 has gotten heavy use on cross-country flights, and even on the beach to charge the battery on my iPhone (which quickly drains as the display brightness jumps sky high in direct sunlight).
But this power bank isn’t just for charging smartphones; I’ve used it to charge my iPad, Apple Watch, and AirPods — sometimes simultaneously. Heck, it will even charge my MacBook Pro with ease (it’s 140W-capable using USB Power Delivery 3.1).
The Anker 737 is a 24,000 mAh power bank with 140-watt charging support, three USB outputs (one USB-A, two USB-C), and an OLED information display. Use coupon codeWS245UB5BF
Anker says that a fully charged 24,000 mAh battery can recharge an empty iPhone 16 Pro four times, or fully charge an iPad Pro and still have some juice leftover. In my experience, those statements seem pretty accurate. It can charge three devices at once via one USB-A port (18W max) and two USB-C ports (140W max using a single port). One of the two USB-C ports is also used as input when recharging the Anker 737. you may also quickly replenish it from 0 to 100 percent at 140W in just 52 minutes.
However, one of the niftiest features of the power bank is its integrated OLED display. It provides input/output wattage per port, the current battery capacity level, and even the remaining time before the power bank runs out.
With a sub-$80 price tag, the Anker 737 is a well-thought-out power bank that should satisfy even the most demanding travel warriors.
