Prime Power Bank (20K, 220W)

Took this on a weekend trip and it charged my laptop from dead to full twice before I even needed to think about recharging it myself. The 20,000mAh capacity is no joke, and the 220W output handled everything I threw at it without slowing down.

Plugged in my laptop and phone at the same time and neither slowed down, which surprised me for something this size. The 20,000mAh capacity got me through two full workdays away from an outlet.

Took this on a week-long trip and it charged my laptop and phone at the same time without breaking a sweat. The 20,000mAh capacity got me through two full days before I needed to plug it in itself.
