I did a test run with the new TruckFridge TF51A. I started at 8:00am in the morning. I wanted some mass in the fridge so I put in two gallon plastic bottles of water. The water was at around 75°, I grabbed it out of the garage. This turned out to be a bit of a workout to chill down that much water. I started with the battery at 12.86V. When running in the ECO mode the unit draws between 2.5 – 2.9 amps. (I did a test in MAX mode and the unit draws twice the amps – 5.5 to 6 amps – compared to ECO) It ran continuously from 8:00 am until 2:00 pm to reach the set temperature of 36°
5:00 pm Battery at 12.67V and used 20.3 AmpHours
8:00 am (24 hours) Battery at 12.54V and used 28.9 AmpHours
6:00 pm Battery at 12.42V and used 37.6 AmpHours
8:00 am (48 hours) Battery at 12.26V and used 44.2 AmpHours
The initial 24 hours stresses the need to pre cool the fridge and the food/drink going into it. The first 24 hours consumed 29 AmpHours and the second 24 hours used 15.2 AmpHours. The camper was open and in shade/sun throughout the day. The high both days was 86 with overnight low 60.
