We needed a higher power interter to use in our RV when camping without shore power. We needed to power two laptop computers, charge cell phones and PDAs and run a small fan. This Cobra unit reviewed well so I ordered one from Amazon. It was delivered in just a few days (thanks Amazon). It has a solid feel to it, connectors are of good quality, and it is small enough not to be obtrusive in the confines of an RV. I used the cigarette lighter plug and put this on our dining table. The two AC plugs accommodated two AC adapters for laptops. As a bonus, there is a USB port on the Cobra that will supply 5 volts! So, I can charge my Blackberry simultaneously. What a delight!! The unit has an internal fan which only runs as needed. If I'm just charging a cell phone, then the fan does not run - but when I've got a load on - the fan runs and effectively cools the inverter. This is not a pure sine wave inverter but I've had no trouble at all using it with various laptops, pdas, fans, and cell phone chargers. I've not used it to power a TV or Radio (those could be more sensitive to interter noise). After a months use, I'm delighted with the inverter - it meets my needs completely.

This unit is small, light weight, comes with a carrying case, two ways to connect to 12v supply and low cost, what more could you ask for.

I mean what else can I say. I was looking for a midrange product that could travel with us and drive a laptop and a cell phone charger when needed. The price was better than I could get locally and it survived a lengthy road trip driving a Dell laptop the whole way. Now it will do the same thing for shorter trips in state and who knows what else. Did what it said it would do.
