The Choice article compared the
Evakool RF47 (which now I think is the ED50), the Bushman SC 35; the Engel MT45F-G4 and Waeco CF-40 as well as thermoelectric models and the Chescold Dometic.
The article is useful to compare these models but otherwise was limited.
Comparing Waeco (W) and Engel (E) and
Evakool (K) freezer/fridge see below:
Coldest temp reached in 20C: W-17; E-18; K-23/-5
Coldest temp reached in 32C; W-17; E-16; K-25/-2
Coldest temp reached in 43C; W-10; E-6 ; K-19/+7
Cooldown time (40 to 0C in 43C); W1hr; E2.11hrs; K0.53hrs
Temp variation when ambient changes 10 - 43; W2.6;E0.3; K 7.1dividers out/ 13.2 with dividers in
Battery current:average cycle incl on and off times/ while cooling /max in all tests
W1.0 /4.0 / 7.0 amps
E 1.1 /2.7/4.0
K 2.0/2.6/6.0
In the reports they said the Engel was slower than some models to reach the desired cold temperature but on the positive side it draws much less current from the battery ( though my reading means the average is about the same as the Waeco).
The Waeco was quick to cool and good at maintaining the temperature. They didn't like the temperature settings being only available in 5C increments. Low average current draw was good as was the battery protection cutout. Said that the lid did not always latch closed properly.
They also tested the Bushman SC35 which gave a good account of itself with relatively low average current draw and only downside was that in some directions it would cut out on inclines of more than 15C.

Andrew and Jen, did they detail their testing procedure, ie were the fridges full or empty?

In the cool down test they said it was the time taken for the empty box to cool from 40C down to 0C in an ambient temperature of 43C.

okay, for the cool down, that's probably fair enough, but what about for all of the other tests. IMHO, if they conducted the tests with the fridges empty it is essentialy fairly useless.

They didn't mention anything about contents but on the coldest temperature reached readings, they said "The temperature was measured in the centre at mid-height from the bottom to the tip of the lid." It implies to me that they were empty.My Toy - 2001 Landcruiser 100S Turbo Diesel
