737 行動電源（24,000mAh，140W，3 連接埠）

Took this on a weekend trip and it charged my MacBook from dead to full with plenty left over for my phone. The 140W output is no joke, it fills up way faster than the old brick I had. It's a bit heavy in a backpack, but honestly worth it for the capacity.

Charging my laptop and phone at the same time from one brick actually works, which I wasn't sure 140W would handle. The 24,000mAh capacity got me through two full workdays away from an outlet without hunting for a wall plug.

I took this on a four-day trip and never had to hunt for an outlet once, which honestly surprised me for something this size. It charged my laptop and phone at the same time without slowing down, and the little display showing exact battery percentage is way more useful than I expected.
