Portable Fridge Options

Thanks @roadtripper
Sounds good

Looking at several makes of fridge, just trying to get it right first time around lol
Looking at one for off the grid camping, that will either be on its own battery or one of leisure battery
Independent batteries sound good so they can be charged before going, then drop onto leisure battery secondary

I think it's worth filling the battery bay if you can find one at a reasonable price as it makes the fridge very flexible and the space left for it is then used for something useful.

I'm less convinced about having additional ones. For the amount of charge they have there are better options and charging then outside the fridge is slow and needs additional chargers.

Personally I'd look at one of the lithium power packs or a solar panel as they would be more flexible.

Something like a Jackery portable power pack is 518wh
Do you know what WH the fridge batteries are
Just to compare what usage / hourly run time you get out of the power pack

Cheers

I believe it's marked as 173Wh

They're also marked as 15600mAh, which at 11v would be about the same.

You'll get some loses in the power pack depending on what it's internal battery configuration is, many run up in the 20v region to better match solar input and increase AC inverter efficiency. I'd advise using the DC connection, there will be more loses using the AC capability.

As a point of reference this weekend we used it in our i3 and it was running on battery alone from 6am to 9pm in a black car in sun and was down to 40% on the fridge display (5 segments), 50% on the battery display (4 segments)
