Anker Prime Power Bank (26K, 300W)

Plugged my laptop, phone, and earbuds into this thing at the same time and it didn't even flinch. The 26,000mAh capacity got me through a full day of working from a coffee shop without hunting for an outlet. It's a bit heavy to toss in a jacket pocket, but that's the trade-off I'll take for this muc

Took this on a weekend trip and it topped up my laptop twice before I even hit 50% myself. The 300W output really does mean business.

Charged my laptop and phone at the same time on a single charge and still had juice left over. The 26,000mAh capacity is no joke, it's basically a wall outlet in my bag for weekend trips.
