As to whether it is really 'automatic' or not, if it isn't,
surely that will be a serious offence under the Trade

I suspect not, it will 'automatically' charge your battery, trouble is
it will not stop when fully charged. It looks very much like a
conventional old fashioned charger, just the power switch and ammeter.
Modern auto-chargers usually have a button to initiate the charge and
will refuse to initiate if the polarity is reversed - no sign of that.
Personally, I dumped that sort of charger decades ago.
All you need to prevent wrong connection is an internal relay with the
coil fed via a diode from the battery. That's been a feature of many for a
long time.
