Pros: It's compact

Cons: Built quality, noise.

Overall Review: I've owned this unit for over a year. Largely used to charge our kids Samsung Galaxies on the road when traveling in the car. I have three power inverters: one Peak, one Cobra and this Rosewill. The Rosewill was the newest addition but it was the loudest of all three when running(had a constant 'whistle' when running) and died first. I've owned the Peak and Cobra units for 1 1/2 and 2 years respectively without a single problem and they are quiet. This Rosewill did the job considering what I paid for it on a sale ($20) but I'll be looking at other brands now when I replace it.
