Seat ALHAMBRA Owner's Manual page 160

158 Seats and storage compartments
12 volt socket:
Only use accessories with approved electromagnetic compatibility
according to current regulations.
Never power the socket.
230 Volt Euro socket:
Do not hang appliances or plugs that are too heavy (e.g. a transformer)
from the socket.
Do not connect lamps which contain a neon tube.
Only connect appliances with a voltage that matches the socket
voltage into the socket.
In the event of consumers with a high start-up current, surge protection
prevents them from switching on. In this case, unplug the consumer and
try plugging it back in after around 10 seconds.
Note
Some appliances may not work properly in the 230 volt Euro power
connector due to a lack of power (watts).
The 230 Watt Euro power connector can be modified for 115 Watt appli-
ances and vice versa. Consult a specialist shop for advice on accessories to
adapt the connector. SEAT recommends visiting a qualified workshop.
