Rating: - Good but not great.
It gets the job done, even if a little noisy. However between the mounts and the outlets being side by side, I have issues plugging in the two things I bought it for: phone charger and laptop cord. I had to buy an adapter. Quality and price are spot on.

Rating: - Good enough to drive 2 laptops
The Cobra CPI 450 Power Inverter was able to power both my daughters' laptops during a 10 hour trip without getting hot, and with no noticable noise. The cooling fan does not turn on until the unit gets warm to the touch. Once the cooling fan turns on, the unit quickly cools off and stays cool.

Rating: - Road Trip Must
We used this inverter for a road trip from Miami to Tennessee and back. (over 1800 miles). It ran two laptops the whole time with no problems. Fan is not too loud, you can't notice it when the music is playing. Has the automatic shut off features to protect your electronics.

Rating: - Best inverter out there
By far the best inverter on the market. The fan is extremely quiet compared to comparable models and it comes in an easy to store case. I would definitely recommend this product.

Unit was defective, returned it $8 shipping, replaced it with like kind, defective, $8 return, letter from Amazon widespread problem with this model, could not replace it. Re-fund my money, ordered a Vector $38 plus $10 shipping. Got email no refund on 2nd Cobra replacement order placed 2 months without, could have bought a unit in town for $45 go figure.
