Rosewill RCP-511F 400W DC To AC Power Inverter

Pros: Two outlets, 400W, includes plug and clip cables, spare fuse, clean power, replaceable 12V cables with screw posts. Fairly compact size for a unit with this power rating. Very little EFI noise when using it to power a PC to play audio through the car's stereo. I ran a full-size desktop PC and LCD monitor with this, no problems. And it's inexpensive.

Cons: It's fan is noisy (not unbearable), battery clips shouldn't be used when the car is moving, which makes it a 150W inverter if you're driving, unless you hard wire it into the distribution block.

Overall Review: Be warned, even though this unit does 400W, and has a 40A fuse, most car lighter plugs have a 15A fuse, so you'll have to rewire the power source if you want 400W while the car is driving.

Pros: Small size. Two AC outlets. Good capacity. Stays very cool to the touch.

Cons: Somewhat noisy. No points for permanent mounting.

Overall Review: I just purchased this so I could keep my laptop charged on the road mainly. I've used many Rosewill products in the past and didn't hesitate to purchase this item. Instead of spending $130 on HP's car charger for the TX1320, I spent approx. $46 after shipping and tax. Now, I have the ability to use a decently powered shop light when working on the car (I live in an apartment and have no garage). This thing is great. Since it doesn't have a built in cord and instead comes with posts and detachable cables, I'm going to permanently mount this in my car somewhere, though I'll have to make my own bracket to hold it in place. I'll just run a 4ga or 6ga wire directly from my batter to the inverter and ground to the chassis where ever I mount it. Overall, I'm very satisfied with my purchase and look forward to many years of use!

Pros: Price on sale was great. Unit will actually do 400 Watts, I've found most will not do what they claim. Neatly packaged.

Cons: As others have pointed out, the placement of the power switch could be better. With some plugs you could shut it off plugging something in. The wires for the accessory plug and battery connection run quite hot at high load, they could be a gauge or two heavier.

Overall Review: We test inverters at my place of employment. Basically we take imported inverters (and other products) and verify their function vs the manufacturer claims so that the importer can verify they are getting what they expect. Most cannot do the continuous rating that is claimed. I verified this one will do 400 watts just fine. It draws around 40 amps with 400 watts load. The unit shuts down on overload about 430 watts (if it didn't you'd blow the 40-amp input fuse). The surge ratings on these units are pretty much meaningless. None of them will do much over their continuous rating even for a fraction of a second, including this one. Also, this is NOT a modified sine inverter, it is a squarewave inverter. Fine for most loads, but be aware that wall transfomers, brushless ac motors, some fluorescent ballasts etc will run somewhat hotter with this type of inverter.

Pros: Stays cool, very quiet, power cord location is perfect for where i mounted it under my glove box to reach my cigarette lighter. It powers/charges my laptop and my cell phone simultaneously, while my last 350 watt inverter could barely charge my phone, whether the car is on or not. Looks very clean and professional. Extremely compact and efficient design makes using this unit enjoyable and fun to show off.

Cons: Absolutely none.

Overall Review: Use my laptop and various battery chargers all day in my car for work and my 350 watt inverter just couldn't pull its weight. Got my Rosewill 400W in the mail and it's performed 110% better than my 350W and looks amazing mounted under my dash. Almost looks like part of the car. Will buy Rosewill again!!

Pros: the inverter works great and i have had no problems with it....

Cons: the inverter runs loud.... almost gets to the point where it is annoying...

Overall Review: although it is loud the unit never gets hot no matter how long you run it.... but i wish it was a little quieter.....

Pros: works just as it should

Cons: na

Overall Review: you have to remember to have the unit switched off before connecting it to the battery otherwise it will blow the fuse. I forgot about the switch. Not a big deal though, just funny that I remarked on getting a spare fuse that I probably would lose from not using it, then less than 5 min later, I have to retrieve the box to get the spare fuse

Pros: Does exactly what it says. Running my carputer off it until I stop being lazy and fiberglass a mold and run a wire through the dash.

Cons: Fan is kinda loud. Who cares though?

Pros: I does what it's supposed to do. You can't beat the price either. It's nice and small too.

Cons: Con...? Nothing really...
