240v shore to onboard 12v

[budgester]

I've just bought a Westerly Griffon and the 240v power basically goes into a 4 way extension lead that power 4 double sockets around the boat, but there is no connection/bypass to allow it to step down to 12v.

Coming from a camper van this was standard practice and there was a Zig convertor.

Would there be a boat/marine equivalent ?

A basic battery charger?

Like this one from Sterling It says it has a power pack function, which I suspect means it can be used without a battery connected (many "electronic" chargers sense a battery voltage - so won't work without).

Anyway you need to charge your batteries??

What he said. Connect the shore power to a charger, the charger charges the batteries, and the batteries supply the 12V side of things.

Looks like your Zig thing is a battery charger of sorts.

Standard practice on campervans is exactly that. External power direct to 240v and battery charger, battery charger to battery, battery supplies 12v. On a boat you can either do this or have a combi (combination charger and inverter) this supplies 240v direct from batteries when not on shore power or allows 240v shore power directly through and acts as a battery charger as well. The first alternative is cheaper if you don't need an inverter.

I emailed Sterling and that nice Charles replied to say his power pack models work without a battery being connected.
Dunno in what circumstances (in practical terms) that feature would be really useful, but there you go...

It would mean you can still run your onboard 12 volt systems while connected to a 240 volt supply even if you dont have a battery on board.

Very perspicacious of you, young Sir.

I can see a lot of folks queing up for that feature
