Just finished a 24 hour run. The fridge had one gallon of water in it and nothing else and kept a temperature between 33 and 35 degrees. Consumption was 417 watt hours, which is about 28% more than Whynter's spec (325 watt hours). My fridge was set a little colder but I'm not sure that would...

Fridge ran for 15.5 hours overnight and the Jeep started right up. Battery was at 12v which is a little lower than I'd like but doable. Putting the fridge on a Ah meter now for a 24 draw test with the same contents.

Agreed. That Whynter chart showed 12v and 4.5 amps is about right based on my testing at that voltage but the voltage is definitely going to vary in real world use.

Thanks for the offer but I have an Ah meter. I'm going to set it up on my bench supply and do a 24 hour test tomorrow night (going to run another overnight test for a longer period tonight).

That DYI is sort of ridiculous, especially when you add in the price of a suitable inverter.

The fridge ran 12 hours last night on a mostly charged new battery. Voltage this morning was 12.5 and the Jeep started right up. I'm annoyed I was chasing a battery problem but happy it was just a battery problem! My Whynter seems to draw around 4.5 amps with the compressor running at 12v.

That's a great chart. I hadn't come across it before. According to it, I should be in good shape with the Group 24 marine/RV battery which is rated at 81Ah. I'm not trying to get 24 hours out if it either. 18 is about all I need. Just setup another test with a (hopefully) fully charged new...

Got the new battery and I'll be installing it shortly and testing overnight. Had the fridge set to 41 degrees last night and the battery was in worse shape this morning than the previous day when the fridge was set colder. That leads me even more towards the battery being suspect. I'll know...

I wasn't paying attention either. Group 34 is stock. I've been using a Group 24 marine battery for years. 140 minute reserve capacity. I'll try and get a new Group 24 tomorrow and test and we'll see what happens.

Oh? What's wrong with the Odyssey (besides the price)? Just did a check with the compressor running. 12.48v at the battery and 12.20v at the Anderson connector leading to the refrigerator. The refrigerator display was showing 12.00v. Probably some loss in that stock DC connector. So, the...

I've checked the coil, compressor and fan and everything is clean. I'm hoping it's the battery combined with the lower thermal mass of the refrigerator not being close to full. I also have it set around 33 degrees as well.

There's definitely some parasitic draw but I've never bothered to quantify it. Probably worth doing so at this point and easy enough to accomplish when I swap the battery again. I'll also have to change my habits of leaving things like the tablet and other devices charging when the engine is off.

Yep. It's just a starting battery. I'm hoping to avoid a dual battery setup due to the space required and the cost. The Jeep is a daily driver and the refrigerator is only hooked up for trips so I'm not concerned with the day to day care and feeding of the battery being an issue. The 14...

The battery is a bit of a story... I just installed it yesterday. The two year old Costco Interstate battery that was in the Jeep bit the dust (I'll be getting it replaced under warranty). I had an identical Interstate green top battery sitting in my garage on a trickle charger that I put in...

Thanks for the feedback. I'm actually very experienced with 12v power systems, batteries, solar and proper fridge/cooler prep. What really caught me out here was this first test experience versus the real world experiences I see with friends that have the same or similar refrigerators. Most if...

Right but one would expect the duty cycle on the compressor to be much lower that 100%.

I have a new (to me) Whynter FM-45G refrigerator that I'm getting setup for the first time in my Jeep Wrangler JKU. I tested the setup last night and the results have me concerned. I have the fridge set around 34 degrees and I left the Jeep at 10pm with the battery fully charged. When I went...

Local pickup where?

Still available and open to offers. Lots of interest but no takers yet. Thanks!

I have a brand new, in the box, never used or installed Sunday Campers SRT01S-48 roof top tent for sale. This tent is virtually identical to the CVT Mt. Bachelor Standard Pioneer (the only difference being the color and logos). The tent is 48" wide and 96" long when unfolded and 48" by 48" by...
