is this a fantasy?...

maybe the unexpected promise of a sunny weekend has got to me - but -
i was wondering if this -
http://www.maplin.co.uk/p/ring-12v-modi ... rter-a23ju" onclick="window.open(this.href);return false;
was the answer to all my power needs in the van -
fridge n tv for the kids - plugged in driving along?
no need to look for sites with a hook up - camp anywhere - plug in - use kettle - cooker - laptop etc - (i'm assuming if you keep the engine running - it shouldn't drain the battery at all?) -
wintertime - start engine - plug in - turn on fan heater to warm van through/demist windows -
the dreams roll on
have a leisure n starter battery - so could wire up invertor to both (as recommended by manufacturer) -
what could the down side be? -
other than cost of initial purchase - and extra dosh for fuel?
as always yr thoughts would be much appreciated -

Oh if only life were that simple.

The supply to the unit is 12v
Just 1kW at 240v = 84amps at 12v = 25mm supply cable
Alternator rating 90amps (if you're lucky enough to have that size fitted)

Average kettle = 2kW

Put the fridge on gas and throw the kids outside with a football

Small inverters are great for phone chargers. laptop etc but you'd be buying a sledgehammer to crack a nut there.

If you had a massive bank of leisure batteries as found in a massive RV or off-grid home, that would be a useful bit of kit, otherwise forget about fan heaters and mains kettles

When not on hook up, my fridge runs on gas, or 12 volt when the engine running, I boil the kettle on the gas hob and have a propex heater. I have a small, cheap inverter running from the leisure battery for charging the laptop, and the phones charge from 12 volt usb adapters.

The supply to the unit is 12v
Just 1kW at 240v = 84amps at 12v = 16mm supply cable
Alternator rating 90amps (if you're lucky to have that size fitted)

...and it's a SIX kW inverter! So that's just over 500A at 12v. That's about the CCA rating of most larger batteries - Cold cranking amps - or how much they can possibly deliver to a starter motor. An 80Ah battery would be _UTTERLY_ flat in less than ten minutes at that rate...

Thanks so much for your thoughts - I thought it might be a bit to obvious. Right!Football and slow kettle from the charger it is Thanks again

slow kettle from the charger it is

That's what gas is for.

what about one of these as an option, obviously cant use it whilr driving

interesting .... i was trying to avoid gas/oil/petrol power sources... as a self generating leccy unit sounded the most cleanest/safest option - but - like everyone else who has commented - thanks for your thought
