The ignition must be switched on in
most vehicles to supply current to the cig-
arette lighter.
No voltage present in

Try using another plug socket.
The cooler has been
connected with the

Check how the cables are laid for
the cooler.

cool properly when the
vehicle engine is
switched off.
The battery voltage is
not sufficient for running
the cooler when the

If the plug of your cooler becomes very
warm in the cigarette lighter socket,
either the lighter socket must be cleaned
or the plug has not been assembled
