Can anyone recommend a good value adaptor for converting the 12v socket on a boat to a standard 3 pin socket such that I can run an Ipod or similar.

Many thanks

Your converter will end up using as much power as a whole bunch of ipods just to cover its losses.

A straight 12V-to-whatever-the-ipod-wants adapter (I presume you can get such a device to run the thing off a car cigarette lighter socket) will be both cheaper and less of a drain on the boat's batteries.

An external battery might be the answer - 250 hours!

Firebox also do a 12v Ipod charger

Cut out the middle man (12VDC-240VAC inverter) and just step it down to 5 volts!

Disclaimer: Havn't the foggiest idea what the 12V socket on a boat is supposed to look like, but I'm sure a bit of creative wiring would sort out any car-boat dissimilarities!

12v inverter is what you want- you only need 150 watts- cost you about £16 from Halfords/argos and other similar places- far cheaper on eblag

you want a "modified Sine wave" not stepped or standard wave. Pure sine is perfect but a lot of money

iPod USB charger on ebay, 12V car/boat type, around £2. Plugs in to 12V socket and has a USB power output, just plug in the standard ipod charge lead.

Inverter will suck power in a big way, be more expensive to buy initially, and harder to stow. Hardly worth it!

I have an inverter on my yacht, bought for charging laptop, odds and sods etc. I ended up buying a proper 12V laptop charger (less power), and haven't looked at the inverter since. There's just very little you need one for on a boat, as most electronic stuff will run from 12V anyway!

I'd buy a 12v charger for anything I need to run in a vehicle regularly but an inverter is a god-send when you need to run something un-expected.

As said above, the 150w ones are cheap and will run most things (including hair straighteners when I take Mrs Will camping rolleyes). They are also not much bigger than a beer can, so aren't exactly a hardship to have around for the odd occasion you need one.

Thing is on a boat, you never do find anything 'unexpected'! It's either there, or it's not....

Not sure if the OP was sailing or motor boating, certainly sailing, you would avoid 150W like the plague or you'd get yourself low on power very quickly!
