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.

Pros: Fast Shipping, that's about it.

Cons: Case heavily scratched, something broken inside case as it rattles simply removing it from the box, system shuts down every 5-10 minutes for no reason, experienced the 'blue screen physical dump' 3 times within 60 minutes.........that was the last straw, it's getting returned tomorrow.

Overall Review: I've purchased many refurb'd units over the past 5 years, this was certainly the worst unit I've ever received, case very rough and system not stable, will go back to the seller I previously bought from thru Newegg and the Lenovo products, those have been outstanding.
