Mini Fridge Wattage

I'd say it probably has quite limited performance. If you just want to keep some drinks chilled, it'll probably be OK. Think "hotel minibar" performance.
 
If it takes 106 kWh / year that's a tad less than 15 watts. Of course it will be more than this when running but there will be substantial periods when it's not running.
In other words it doesn't look a lot different from compressor fridges designed for boat/camping use, but of course it's cheaper.
On the other hand it's not designed for marine use and, as noted, there will be power losses in an inverter.

Agree, it is not a marine fridge, so it will only last for perhaps 5 to 7 years instead of 8 years or so, mainly due to likelihood of getting rusty, however, does not matter which way you look at it, it represents an excellent value for money, it also has a freezer compartment. It will be good for the marina and not too bad via the invertor when at sea, I could even switch it off and using as a cooling box for a while if need.
 
"This refrigerator is not designed to be used in an outbuilding – both your food and the appliance can be damaged. Do not use it in any unheated area."

This statement always intrigues me. Why ever not? I have had freezers and fridges in my unheated garages for as long as I can remember. They use far less power than inside a heated house and suffer no detriment. (I suspect this standard statement really relates to single-compressor fridge-freezers which can indeed have problems because of the imbalance between the compartments)

Our fridge freezer in the garage stops working in freezing weather. So possibly refering to extreme coditions!
 
Most domestic units say don't operate fridges and freezers in unheated outbuildings on their blurb. I am sure there are reasons they could go wrong especially when its colder outside the fridge than in it. Your fridge contents could freeze and then thaw without you knowing it if its goes below zero outside. having said that we have a fridge that's been working ok in the garage for about 25 years, Its a beer fridge mainly.

If the fridge is 50w then when running off 12V and an inverter that's 4+amps without losses. If it runs for 5 mins in every 30 then over a day will consume 16Ah. I saw somewhere inverter losses can be 20% of the load so call it 20Ah per day. (Do inverters use power even when not supplying any to the load? if so add that too)

By comparison my compressor coolbox uses 10 Ah per 24 hours on a 12V system with the thermostat set to 4 C in a typical Scottish summer (i.e. temperature not often above 20 C).
