Rear 12v socket amps Golf mk7

[JABB]

Afternoon.
Anyone know what amperage the supply is to the rear cigarette socket in the boot of a mk7 golf?

i've had a quick look at my Golf mk7 handbook

It says no single socket to be over 120w and no combination of devices over 190w
The fuse is 20A

Thank you very much. I want to run a max 8.5a radio. That should be fine then
