Cheap and works
Comment:
So far it has worked great. stores easily in door pocket and easy to install and use. |


Noticed that my cell phone was not charging. So I measured the output voltage with a multimeter. Although the manufacturer advertises an output of 120 volt, under no load the output is actually only 90 volts. Therefore, it will not charge electronics, but discharge the batteries within them yet lower. I do like the USB port on the side, but again, don't know if it will actually charge the appliance.
