Mars 3

Kept this in my bag all week and it handled charging my phone and earbuds without a hiccup. The compact size is what sold me, it barely takes up any room next to my keys.

Didn't expect something this small to feel so solid in hand. It slides into my jacket pocket and has enough juice for a couple of top-ups when I'm out all day.

Keeps my phone topped up through a full day of meetings without weighing down my bag. The compact size means it just disappears into a jacket pocket, which is exactly what I wanted.
