Question:
is there any way I can plug my electric toothbrush in so it can charge while I am driving or sleeping?

Answer:
Try the old fashioned way of using a regular tooth brush.
Answer:
You might want to try a Crest SpinBrush while on the road. No recharging required, uses AA cells... just carry some spares.

Answer:
Use a Power Inverter.

Answer:
Get yourself a power inverter. A 300 or 400 watt inverter will do the job and then some. You can pick them up for around $30. You can also use it to power a TV/VCR, run a lap top, and several other small applicances.
Answer:
I didn't know there were any truckers with teeth!
Answer:

That's funny. but they had trouble recharging the Brushs.
Answer:
We have the Sonic care brushes. We charge them at home. We go home about once a month. They last 2 brushings a day easy. When we go home we set them in the charger.
If we stayed out longer we would just bring the charger with us and us the inverter. You will find you will need at least a 400watt inverter (plugs in cig lighter) for alot of things. Like charging razer. Powering TV if it needs 110volt. Charging cell phone if you do not have 12 volt charger and so on. Get on at Wal Mart. The truck stop charges WAY to much for EVERYTHING Except DR. Pepper. The Pilot is normally a dood deal.202 N Main Street

Answer:
Which ever Power Inverter you get......Do NOT get the VECTOR brand!!!
I've had 3 of these in the past 30days b/c SPARKS would come out & 2 of them actually caught on fire.
BTW, I bought them from Wal-Mart.

Answer:

Dang it Rokki. Quit being so rough on things.
One of my invertors is a Vector brand 400 watt. I have had it for about 2 years now and never have had a minutes problem with it.
Any change that it is the power outlet you are pulgging it into. Maybe something that is causing a partial postive ground????
