User Reviews about Cobra CPI 480 400 Watt 12 Volt DC to 120 Volt AC Power Inverter with 5 Volt USB output

I have this for only a week now and its working good.Its quiet even I use my 65watts laptop as oppose to other reviewers.This inverter is only a little big for its size and the direct to battery cable is too short.aside from that,it shipped fast and working fine with my gadgets.Will add another review later after a few months.Thanks. -- Cobra CPI 480 400 watts Inverter

Just purchased this inverter to replace my old Vector one. What an improvement! Much quieter. I mainly use my inverter to power my laptop computer, and this inverter doesn't seem to make much noise at all. It seems quieter than the laptop itself. Overall build quality looks very good too. For the price, you can't do much better. I do wish they would offer the remote switch option like the more powerful models, but that's the only thing I can think of. -- Great power inverter

I order several of these for our sales team. They have a printer and laptop in each of their trucks. They all shipped at the same time and so far, after at least a few weeks, no complaints from any of them...A VERY good sign :-) -- Works for us

it does exactly what it says it does and its super quiet.. however the mounting tabs are under the sides which makes it impossible it mount it without swearing at it till you give up and just mount it with screws at an angle... -- its an inverter!
