Just wondering if anyone has used the Waeco Coolpower 36 12v power pack , there seem to be so many different options on the market, from El-Cheapo 12v power packs, to the Waeco Coolpower 36. They provide a nice option for running a fridge on 12v or other 12v items such as lights etc.

Hi TF

All Power Packs have their place but look at the options...

Can you fit your choice of battery to it ?

Can you jump start off it ?

What is its A.H. rating ?

Will it fast charge off your car battery / alternator ?

If left connected will it drain your starting battery ?

If it is supplied with a lighter socket charge cable then stay away from it for fast charging. They will run your fridge for 8 hours and then need 24 hours to re-charge.

Regards Derek.

Yes, to prevent confusion.

Approved by ARB Corporation.

Thats good, hopefully everyone will be happy now, and we can exchange / impart knowledge to one another instead of fighting over a logo.

(which I'm sure if ARB thought you were threatening their sales they would have confronted you.)

I understand that those who objected had their reasons (and please dont start another thread about this) but hopefully now that you have ARB approval that one is finished.

I think I'm getting older (42) but I seem to be going to more funerals than I'd like to nowadays, life is too short, we should all enjoy it while we can, and live every day like its your last, ......cos someday it will be.

Whilst we are on the subject if we are talking a 38 amp hour battery and a Waeco 35-40 litre fridge consumes around 1 amp per hour, does that mean 38 hours, or do I have this wrong.? I read the test done on the Waeco CF-40 done by Australian 4WD monthly and it saidthe Waeco consumed 22.5 watts over 24 hours and that include aan ambient temperature of 50 degrees at one stage.

22.5 amps sorry over 25 hours, not watts.

4WD Monthly tested in a cycle ranging from 15 to 55 degrees and for a Waeco CF40 the total consumption over 24 hours was 22.5 amphours (not amps, not watts).

However this does not take into account -
1. If it is 55 during the day, it will be warmer than 15 all night.
2. Opening the fridge will increase consumption
3. Put warm food/beer will increase consumption

I would work on 30 to 40 amphours per day in the real world.

TerraFirma, as you can see they will run a fridge - but not for a long period of time, and as has been pointed out they take a while to recharge, and also cost more than a decent large AGM Deep Cycle battery !!!

We recently bought 2 x Coolpower 36 packs from Fridge Shop @ $220 each. Used them on high country trip for 2 weeks, running Waeco CF-40 (in its insulating cover). The power packs use AGM batteries. We didn't get the expensive cable to link the two power packs (72 a/h fixing kit), but it is normally thrown in with some packages.

We also got a Waeco RAPS-12 wiring kit, wired straight from battery. It has two sockets, one Hella and one cig lighter. That was well worth the money.

We camped 7 nights at one site (on Davies Plain). We only used the CoolPower packs to run the fridge. (We have a small jump starter pack, which ran other things like airbed pump, and charged rechargeable batteries in our lanterns etc.) We turned the fridge off overnight and kept the temp between 0 and 5 deg (thermometer with probe is invaluable), alternating the power packs. The weather was sunny each day, tops between 20 and 30 deg. Nights were cold (down to about -4 one night). Some days we didn't go anywhere, some we drove for 2 - 5 hours. When driving we plugged the fridge into the vehicle 12v accessory socket and the two power packs into the Waeco RAPS-12. One power pack plugged into the Hella socket and the other into the cig lighter socket on the RAPS outlet.

By the end of the week, both packs had gone from about 12.9v (about 85%) to 12.2v (about 40%). I found that the power pack plugged into the Hella plug charged a lot faster than the other one. They both charged up sufficiently with a long day's driving. The one plugged into the Hella socket would charge from say 40% to 70-75% in about 4-5 hours' driving, the other one half that.

I would say that this was just enough for this kind of trip. The wiring upgrade kit was essential. This setup would be fine if driving more frequently. For longer stays, or in very hot conditions, or if the fridge is used as a freezer, I would look at larger power packs/dual batt system (e.g. 120 a/hr AGM) and/or solar panels.

Note that only one of the CoolPower packs came with a plug that could be used in either Hella socket or cig lighter socket. The other one only had a cig lighter plug. Worth asking before ordering.

If you go this route I would also suggest getting a good lightweight portable 2-stage or 3-stage 240v AC battery charger, to charge up the power packs before leaving and when staying in town.

A portable pack means your fridge is not tied to the car all the time, but it is more of a hassle than a good dual battery system.

Hope this helps.
