We recently had a family reunion and it was so hot out that I sure could have used a fan but there were no electric outlets in the area we were picnicking so the fan was out of the questions , well the electric kind of fan was that is, instead we had to use homemade fans that one of my aunts had made and they did work but electricity would have been great soooo i decided to check into getting something that charged by the cigarette lighter in the car and had an electric outlet and stumbled across this Poweradd 150.
This power inverter has a metal frame and is small and lightweight which is something I really like, it doesn't take up a lot of room and can be left in your vehicle glove box, console, or door panel.
The 150W is made more for things that don't take a lot of juice light your cell phone chargers, tablet chargers, and other smaller things. There are also two USB ports so you can actually charge two items with the ports and one with the electrical outlet. It has ventilation in the back so it doesn't overheat.
