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

I connected two laptops to this inverter (15.6 inch Asus U53JC and 10.1 inch Asus 1005PR netbook). While running, they were well charged, meaning there was enough power to both start and charge at the same time. The inverter makes a high-pitched noise and you can also hear the fan, but this is normal for these devices. It's not too loud. I'm pretty sensitive to noise, but it didn't bother me. The device is compact and well made. The 12V plug requires some force to connect, but nothing out of the ordinary, and it fits snugly into the car's 12V socket. The AC plugs enter the device with normal force. Two standard-size three-pronged AC plugs are fine, but you can't connect two devices with adapters instead of regular plugs. I am satisfied with this inverter, it works well and is worth the money.
