[Closed] Power usage numpty question

Going camping next week for a full week and have made up a power supply for the electric hook-up on-site.

The supply is from one of those IP44 (?) hookups you normally see on campsites so I have got the 'male' plug rated at 16A and coupled to some 16A rated 3 core flex. At the other end is a 13A rated 4 way gang.

We won't be running anything more than a small (fan only) beer fridge, phone charger and a 7W (low power bulb) clip on lamp.

I *assume* the total draw will be nowhere near 13A but thought I would ask, just in case like.
