Review on PowerLine 90307: Ultra Efficient 140/200 Watt Mobile Inverter with USB Power Port by John Munajj

Have been using this stuff for over 6 months now. I haven't had any issues with two connected gaming laptops. Note that your AUTO may have FUSE on the port you are using, so you may have problems. My 2007 VW does fine with it. This thing or something is simply necessary for long trips. I kept it plugged into my car all the time and occasionally used it in other cars for long trips. This thing saves lives. The USB port allows you to charge your phone while still using your laptop. The light will glow to show it's plugged in and the USB port is active (the top green light), and when you turn it on, the second green light will glow. informs you that two sockets are active. At 375 watts, it does get a little warm - I've seen that from personal experience - but it doesn't overheat or overheat. Its cooling system is pretty good.
