Yep. Correct.So I've read quite a lot / most of this thread, but I'm a bit confused over the battery usage as the battery capacities mentioned in the thread are quoted as AmpHour
I have a portable power unit with a 1024 Wh capacity. So in my head that should run a 60 Watt coolbox/fridge for 17 hours (1024 / 60)
Or have I got that all wrong?
If it's TE or absorption it will be a constant power draw. Ie 60w/wh.
But if it's a compressor fridge or will cycle on off giving you more run time as @Howzat mentioned above.
also for reference a 100ah lithium will have about 1200wh power.
A 100ah AGM will have about 600wh (50% dod)
....
100AH x 12 Vdc = 1200 Watt-Hours Therefore a 12Vdc 100AH battery has 1200 Watt-Hours of capacity. The Watt-Hour capacity of a battery bank is the sum of all the batteries connected in the system.
