Seems to work just fine -- have only used it for cell phone and small game units.The advantage of this smaller unit is no fan - quiet.Some devices will require the power of the larger (noisy fan) model.Low cost inverters such as this produce electric power that is an approximate sine wave as opposed the perfect sine wave that come out of a wall outlet -- as far I know this isn't a problem for typical consumer electronic equipment, laptops etc -- but it's probably worth checking the user manual of the device to be powered just to make sure there are no precautions about using it with an inverter.However, the AC motors in things like power tools and appliances may run a bit lest efficiently when connected to an (inexpensive) inverter.

*** Update ***

We've used this with a variety of cell phone/ipod/handheld game chargers and so far haven't experienced any problems.

I thought this power supply did better than I expected.Running a Dell D610 under normal use, I got about 50 minutes with.Given that it has 4Mah of storage, that is better than I could have hoped for.I would caution anyone that thinks they should get 9 hours of computer battery life to read the specs and understand what the power requirements of a computer are. There isn't an easily portable product on the market that can do that. A gas generator would but they don't allow those on airplane for some reason???All kidding aside, one issue that anyone using this with a laptop should realize is that it won't automatically kick the computer into an energy saving mode like it does when you switch to your internal battery so the power draw will be higher and the battery won't last as long even though it is rated pretty close to the same capacity as a normal laptop battery.Anyway, it does well charging my gadgets which is the real reason I bought it anyway.It is worth spending the extra money on this instead of the smaller one because it will give a full charge to the palm, camera battery and the cell phone at the same time.
