I think that connector is an SAE connector.

The power adaptor is 12V 1.5A (pretty easy to find, won't matter if you get a higher current one).

You could make one (or search Amazon/Jaycar/AliExpress).

Can downgrade the fuse.....

Just get a battery charger and clip on to the jumper clips, that is what I did.

Somethink like this is the cheapest I could find.

If you have an old 12VDC wall wart that is not a switch mode PSU, cut the end off, put on a couple of crocodile clips and hey presto.

Donlt leave the charger connected all the time, use for a few hours every few weeks to keep topped up.

I too, would just clip my car charger to the crocodile leads. (it's a 5 A Ctek smart charger, but it has the option to turn down to 0.5A). Being a smart charger, that one would be fine to leave connected for months.




If you want to build a dedicated charger, assuming that socket is directly connected to the SLA battery inside, you would want a 12V sla charger (will run at 14.4V for bulking then ~13.6V float), not a 12v power adaptor.

For example this one:

Note this one is not suitable for leaving connected for a long time.
