Rally 7460 GameDay 12V 200-Watt DC to AC Power Inverter w/2 USB Ports & 3 AC Outlets (Red/Black)

• 200-watts of power output
• Converts your vehicle's 12 Volt DC power into a household 120 Volt AC power
• Three (3) 3-prong AC outlets
• Two (2) Type A USB ports for charging cell phones, iPhones, iPods, MP3 players, digital cameras and more
• 8-feet DC power plug, approximate length

I use this in the car to power a 12 volt, 15 watt mini-amplifier for a speaker system. It works fine. I haven't used the USB ports yet. It has an all plastic case though instead of metal. I would not drop it on anything hard or use it outdoors although it says it is for tailgating. It automatically turns off so you don't run down your battery. I actually paid a lot less than the current price and would not pay more than $50 for it, however it is the most affordable I have seen with 200 watts, three AC outlets and two USB outlets, all with covers to keep out dust. My main complaint is the whining internal fan that cools it. Even while driving and listening to music fairly loudly, I can hear the high-pitched, annoying noise. I put it under the passenger seat and still hear it. Another plus is a long plug cord which lets me move it around, out of the way, under seats or up on a seat. I may find a place where the noise is not a problem if I dont mind the power switch being out of reach while driving. I am also looking for some kind of soundproofing material I can make or use.
