I asked the same question on the samba and here's the answer:http://www.thesamba.com/vw/forum/viewtopic.php?t=127433that invertor is exactly what i was looking for...cool thing is, i could easily hardwire that convertor and just switch on the 110 switch under my jumpseat to power the inverter now to find a 3 way switch so i can cut power to the battery and turn on power to the inverter. and i know of just the perfect switch. looks like i'll need two inverters, one for the radio, and one for the 1200w amp. thanks denis too, that would be a real simple way to address the problem as well. and i'll probably look into that too.From: coocoo@xxxxxxxxx: tcb@xxxxxxxxxxxxxxxxxxxx: [tcb] Re: use shore power for radioDate: Mon, 17 Nov 2008 08:36:30 -0600 Gerald has all that knowledge. He has setups that will do that for a price, same as RV. But, if I understand you right, You can by a "trickle charger", also known as a "battery tender". It's a little box that hooks to your battery just like a charger, and plugs in to 110. You can run all your accessories forever. I unhook my coil so that it wont get hot and ruin your points. ----- Original Message ----- From: Brian Denning To: tcb@xxxxxxxxxxxxx Sent: Monday, November 17, 2008 8:28 AM Subject: [tcb] use shore power for radio Every topic i read on powering accessories in a camper is based on using an aux. battery, a power inverter, etc. My question is, for those of us lazy bums that enjoy camping where there is a 110v hookup is there a way to hook our radios to that, so that the radio is powered off the 110 and some sort of inverter instead of off the battery? My westie is way to low to go out on some random trail and out in the middle of nowhere and camp. I prefer to have showers close by but "rough it" in my little "RV". Is there something or some way to make the radio in my bus power off of 110? The idea i have is some sort of switch to switch it from battery power to 110 power. after doing a search on the samba the only thing i can find is "i don't want to be on shore power" or "Aux. Battery hookup" all things to get away from the trusty 110 at campsites. i want to hook to the 110. my ultimate goal is to be able to watch a movie in my bus using my bus' radio as the sound source. some of you may say bring a boombox with you. To that I say, there's not room after loading the ice chest, the chairs, the side awning, the food, the bedding, the beach cruiser, the two dogs and the wife.
