Charges my laptop and phone simultaneously
Took this on a 3-day business trip to Chicago. Charged my MacBook Pro from 20% to full twice and still had enough left for my iPhone. The Lithium Polymer Power Bank is exactly what I needed for travel days when outlets are scarce.

TSA-approved and powerful
Flew cross-country with no issues at TSA. The capacity is real — I got about 4 full charges on my iPhone 15 Pro. Build quality feels solid. Worth every penny for anyone who travels for work.

★★★★☆
Great capacity, slightly heavy
Does exactly what it claims. Charges my devices fast and holds a lot of power. Only downside is the weight — but that's expected with this much capacity. Would buy again.
