DBTech 175 Watt Portable Micro Power Inverter With USB Port - 12v AC to 110v DC Car Plug Converter For Your Ipod, iPad, iPhone, Tablet, PSP, DVD Players Laptops Netbooks And cellphones
Not terrible, not great.  We will still be able to get some use out of it.  We bought two different inverters.  This 175 watt inverter cannot keep up with the more expensive brand 112v AC to 110v DC Car Plug Converter rated at 145 watts.  Next time we'll spend the extra money for better quality.
