This is kind of a random thing but I thought some of you might be doing travelling for the holiday season and this thing is awesome.
You can get a Vivitar Power Inverter for $7.50 right now plus $3.99 shipping. That is a great price for these guys- I am pretty sure mine was $20 and I had to hunt all over to find it.
You can plug this into your cigarette lighter and plug in any cords or cables for electronic devices. It keeps the device charged while you are in the car.
I use this all the time- especially when we are on road trips. I can work off my laptop or have the children’s various devices plugged in during the trip and I don’t have to worry about a dead battery.
