a light,

Probably less than 100 Watts

and a wireless router.

30 Watts

All ten sockets are used up...
i'd guess 13amps are well used up?

Nowhere near!

Probably a total of just over 1000 Watts if everything was switched on -
or around 4 to 5 Amps.

The handbook for each piece of equipment should give the power usage
figure
