The short answer on compressor vs thermoelectric 12v cooler use: a compressor fridge can freeze food, and a thermoelectric roller only cools below the surrounding air. We compared the compressor fridge and the thermoelectric roller on cooling, capacity, power and warranty terms. The compressor side wins on cold, and the thermoelectric side wins on simplicity, since it needs no ice and also warms.

These specs are rated by the maker and quoted from each listing on 10 November 2026.
Cooling power
Cooling power is the split between the sides. The Antarctic Star compressor example states a range of -4°F to 68°F, cooling from 68°F to 32°F in 15 mins and reaching -4°F within 60 minutes. The Igloo thermoelectric example cools up to 36 F below ambient, with no fixed low temperature stated, and heats up to 136 F. Each side here rests on a single example.
Capacity and size
The Antarctic Star lists a 68QT cabinet at 30.91 x 18.7 x 18.5 inches and 37.48 pounds, with a removable divider and a drain plug. The Igloo lists a 43 Quart roller at 21.85 x 14.96 x 19.29 inches that holds 59 cans, with wheels and a locking, telescoping handle; it lists no weight.
Power and noise
The Antarctic Star runs on 12/24V DC or 110-240V AC, states a 3-level battery protection system, and runs below 45 dB. The Igloo runs on 12V DC or 100-240V AC, with both cables included.
What the listings leave unclear
The Igloo spec table says “See manufacturer” for warranty and lists no weight, so the thermoelectric side of this comparison has no stated warranty term and no stated weight. The Antarctic Star lists no power draw in watts or amps, so its draw on a vehicle battery is unstated beyond the 3-level battery protection system.

Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For 12V coolers, safety means battery protection, auto-shutoff or another protection the listing names; the Antarctic Star states a 3-level battery protection system, while the Igloo states none. Only the Antarctic Star states a warranty term, and the Igloo does not. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Antarctic Star 68QT | 9.7 | 32 | 21 | 21 | 7 | 1 |
| Igloo IE42 Roller | 9.4 | 26 | 20 | 20 | 0 | 0 |
Every total is translated into a figure between 9.2 and 9.8 with a linear formula; ranking by points and ranking by score always agree.
How to choose the best compressor vs thermoelectric 12v cooler
Choose the compressor side if food must stay frozen: the Antarctic Star states -4°F and a 68QT cabinet with wheels and a telescoping handle. Choose the thermoelectric side for a light roller that also warms food: the Igloo holds 59 cans, cools up to 36 F below ambient and heats up to 136 F.
| If you need | Look at |
|---|---|
| Food that must stay frozen | Antarctic Star 68QT, -4°F |
| A roller that also warms | Igloo IE42 Roller, heats up to 136 F |
| The largest stated capacity | Antarctic Star 68QT, 68QT |
| The longest stated warranty | Antarctic Star 68QT, 1 year |
Sizing Notes
- Match the cooler to the outlet: the Antarctic Star takes 12/24V DC or 110-240V AC, and the Igloo takes 12V DC or 100-240V AC.
- Check the cabinet: the Antarctic Star measures 30.91 x 18.7 x 18.5 inches at 68QT, and the Igloo measures 21.85 x 14.96 x 19.29 inches at 43 Quart.
- Plan for weight: the Antarctic Star lists 37.48 pounds before food, and the Igloo lists no weight.
- Match the temperature range to the load: the Antarctic Star states -4°F to 68°F, and the Igloo cools up to 36 F below ambient.
