We’ve been carrying the Anker 737 for about three weeks now and it has basically replaced bringing a laptop charger on day trips. The 140W output isnt a marketing gimmick, it actually pushed our MacBook Air from 10% to full in under two hours while also topping off a phone. Thats wild for something that fits in a backpack pocket.

The smart display is genuinely useful. You can see exactly how many watts are going to each port in real time, which helps you know if your device is fast charging or just trickle charging. The estimated time remaining for the bank itself to die is also handy so you’re not caught off guard.

Now, the downsides. This thing is heavy. At about 1.3 pounds its noticeably chunkier than a standard phone charger bank. And at $110, its firmly in the premium category. If you only need to charge phones, theres cheaper options. But if you actually need laptop level power on the go, or you travel with multiple devices and hate hunting for outlets, the 737 earns its price. We havent found another power bank at this capacity that matches the wattage output.
