The short answer

Dometic CFX5 45 comes out ahead by a narrow margin (4.8 vs 4.6). Dometic CFX5 45 is best for: Campers, overlanders and van travelers who run a powered cooler regularly and want accurate temperature control and low power draw in a mid-size, single-zone unit, and who accept a four-figure price for it. Read the strengths below before deciding.

Dometic CFX5 45
1 source$1,049.99as of Oct 10

A 45-liter single-zone compressor cooler that OutdoorGearLab ranked first of the 11 powered coolers it tested, with an overall score of 86. In that test it held 34.7°F against a 35°F setpoint, chilled warm cans to 35°F in half an hour and used 41 watt-hours over six hours. Dometic lists it at $1,049.99.

Strengths
  • — OutdoorGearLab measured 34.7°F inside with the controls set to 35°F
  • — Brought warm cans down to 35°F in half an hour in OutdoorGearLab's test
  • — Drew 41 watt-hours over six hours, per OutdoorGearLab
Watch-outs
  • — OutdoorGearLab found the lid latch finicky
  • — Not the most portable model in OutdoorGearLab's test: 36.2 lb empty on its scale, and it may take two people to carry when full
  • — Single zone only, so it cannot hold frozen and chilled food at the same time
Goal Zero Alta 50
Ranked #4 in Best Electric Coolers
Goal Zero Alta 50
1 sourceall derived$799.95as of Oct 11

Efficiency off-grid is where the Goal Zero Alta 50 leads this group. Its LG compressor averages 8 watts at 35F, so a 500Wh Yeti power station runs the fridge for over two days and a Yeti 1500 keeps it cold for six-plus days. The trade is single-zone operation: freezer or refrigerator per trip, not both at once. For solar-powered overlanders, dispersed campers and anyone building a tailored Goal Zero off-grid kit, the integration story is the clear differentiator.

Strengths
  • — LG variable-speed compressor averages just 8 watts at 35F setpoint, the lowest in this category
  • — App-enabled over Bluetooth with remote setpoint control and temperature alerts
  • — Eco-friendly R600a refrigerant (30g charge) and 75-can capacity in 53 liters
Watch-outs
  • — 49.4-pound empty weight is heavy for the form factor
