Have been using one on an Engel fridge now for nearly two years, including an extended trip through NT and Northern Qld. No question that the fridge worked fine and the battery lasted longer when we were camping.

On previous trips I found that in hot locations, within 36 hours, the auxiliary battery would be below 12v. With the VGR product, I have had occasions when the battry is still running the fridge after 4 days!

hedevil, assuming your fridge needs power to run and has a thermostat to make sure you maintain a temperature. Please tell me what a power saver may do? I would have though a slightly higher thermostat setting would do the same as the advertiser is saying his product does.

Dependent on the size of the battery, and the fridge, I would think that people rely on the fridge going for four days or so, but that would also depend on the ambient conditions too.

max, sounds like a timer that is set to not allow your fridge to work as effectively. I guess you have to ask then if there may be potential for food spoilage. Milk has a very quick deterioration from above 4 degrees, so if it was 7 say because the compressor wasn't allowed to work to requirement. Would you say you saved power or lost quality to your food or the cool ones you hoped at the end of the day. I did read their speil. I would be interested to see them argue the point here.

I think you have heaps of power with your 320 amps. I have 160 or so, plus the start battery.

I reckon you're spot on John.

I regularly observe my thermometer and on a given setting the compressor kicks in at the same temp each time. Last time away I noticed that with the thermometer sensor in the middle of the fridge it kicked in every time the temp hit 3.2. It cycled more regularly in the warmth of the day, and hardly at all during the cold of night.

No real surprise, that is what a thermostat is there for.

Setting a fridge to only run for a certain amount of minutes every so often is just asking for trouble. It will be too warm during the day and too cold at night.

Anyone ever heard of food poisoning?

Cheers,

Jim.

Excuse my ignorance, but what is this device?

I can't find the ad. Help would be appreciated.

Thanks,

Jim.

do a search in the Business section for vgr Jimbo. I think some of the suggestions to circulate more air around condensors would save more.

I reckon if you have your car set up to head up hills and someone holds your foot off the throttle for some of the time as you have a hard incline, you may be upset at the performance.

Thanks John,

I've had a look and agree with you.

Why on earth would you, as a human, decide how often your fridge needs to cycle? I thought that was why fridges are fitted with thermostats.

Their advertising states to avoid the "2 minute on, 2 minute off" thing. What a crock.

I have a thermometer in my fridge and reckon the thermostat does a good job. I'll leave it to the thermostat to decide when the compressor needs to run and when it doesn't.

Sounds like a Hiclone for fridges.

Cheers,

Jim.
