just wondering what others use there 12v for?

i currently only use for lights at night

it is connected to a inverter but dont seem to use it just there realy

when in spain i run 2 computer fans at night , silent and not too powerfull , just enough to keep the air moving!

stereo and amp!- bug jam usually as it can interfere with the locals

Yes I seem to remember a bit of music n flashy lights coming from a van at Dubaid this year, thought you was having a rave in there, we were gutted not to have invites

we looking to use the van though winter

how long would a 300w heater run of a 75ah leisure batt?

no invites needed! its always an open party!

You would be better investing in a Eberspacher.Propex.or a Webasto heater.If you intend on doing some winter camping.

you need 1.6 Kw to heat a van in 4 deg C... and maintain a comfortable temp.

Other twelve volt stuff... I use
Fresh water pump
Propex heater
TV.
DVD player.
surround sound.
Media player.
phone charger.
Lap top.
Hair straighteners.
50 Watt head unit and four speakers

75 ampere / hours means 1 amp for 75 hours or 75 amps for one hour and all values in between (basically, but not perfectly)

a 300watt heater would use 300/12 = 25amps. (1 watt = 1amp of current at a pressure of 1volt so 300 watts = 25amps at 12volts)

a fully charged, perfect condition 75a/h battery would therefore last a maximum of 3 hours powering your heater.

Your best bet would be to fit a Propex gas warm air heater or an Eberspacher petrol / diesel heater - depending on what fuel you use. They work all night long and get the van toastie warm in no time.

Take em back kev.I've seen your hair.And they dont seem to be doing the job very well.

Hair straighteners.

I'll tell Louise you said that.

In realistic terms. For starters you don't want to drain a battery to it's completely flat, empty, dead state as it will significantly reduce the life of the battery. A good rule of thumb (battery type depending) is that you should only drain a battery down to 40% of it's original capacity, or in other words you've only got 60% of the battery to use.

So for example 100 Ah, 5 Amp load example: By your calculation you had 20 hours of time when drawing 5 amps, but in fact you only have 60% of that time, so 20 hours x 60% = 12 hours
If you factor in Peukert's Equation, the more current you draw the time you have reduces even further.

Latest addition to my van is a Three Mi-Fi. So now the kids can access the internet while we are on the move and the van becomes a mobile wi fi hot spot

Could even use it to steam live TV to lap top etc

Before long I think all cars will have it as standard. You can then use an Ipad or similar for all your entertainment, sat nav, telephone calls, e-mail, GPS tracking etc. I know some custom built interiors are already incorporating it. I haven't quite got to that stage yet.
