Hi

Just browsing around and wondered if this would be suitable to keep my coolbox cool when electric hookup is not available. Or does anyone have any other suggestions?

I have one of those and they are ideal for low wattage items such as radios, lights etc; but according to the instructions they will only run a 48 watt cooler for 3 hours.

4 watts = 30 hours

9 watts = 21 hours

15 watts = 12 hours

24 watts = 7 hours

48 watts = 3 hours

80 watts = 1.5 hours

Hope this helps

i dont think any 12 volt power supply will run a cool box for any longer than 6 hr without being recharged. we have had 2 12v coolers + flat car car battery, now got a 3 way portable fridge.

Thanks for the maths lesson - that really helps  - I think I have seen some bigger ones around somewhere

I don't have enough fingers and toes to qualify as a maths teacher but glad it was of some help. I believe Halfords do a more expensive model but I doubt it would run a cooler for much longer.

I originally bought mine to power all the 12v in my caravan but then decided on a proper leisure battery. I used it to power a small TV/Radio/CD player and it had sufficient power (and more) to last a weekend of general intermittent use.

we're going away camping at easter and booked to late to have electric hook up so I'm a bit concerned about how cold its going to be (no heater)

Would we be best getting some sort of power supply or a decent gas heater, I know I'm going to be cold.
