The Field Bureau
How we test.
Every number on this site is a number we measured. We started this bureau because every other AU camping site quotes spec sheets. We don't.
How we test
Numbers, measured. Not quoted.
Every figure on this site comes from our own runtime measurements: a calibrated Victron shunt, a HOBO ambient logger, and a 200 Ah LiFePO4 test bank built into the back of a 4WD. We log 1 Hz for 28 days continuous, in real cab heat. No spec sheets quoted. No press releases reused.

The protocol
- Bench setup. Each fridge runs against a calibrated 200 Ah LiFePO4 bank with a Victron BMV-712 shunt, logging current at 1 Hz.
- Ambient run. A HOBO MX2202 logger records ambient temp at fridge height. We run baseline at 25°C, hot-day at 41°C, and an extreme run at 47°C peak.
- Field run. Fridges live in a real 4WD across NSW, SA and QLD weekends. Corrugations, dust, real cab heat. Failures get photographed.
- Power-out test. We pull the supply, log how long the fridge holds 4°C internally with the lid closed.
- Publish. Runtime curves, average draw, peak draw, hold-time. Raw CSVs available on request.
