How we scored them
The Solar Score weighs performance, build, value, safety and warranty. For an electric cooler, safety means the protection circuitry and certifications the listing actually states, such as the Dometic’s 3-stage battery protection; a cooler that states none scores zero on that line. Three of the five picks state a warranty term. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Dometic CFX2 37 | 9.6 | 32 | 21 | 20 | 5 | 3 |
| Ivation 48QT Cooler | 9.5 | 29 | 21 | 21 | 0 | 3 |
| COHO 165QT Cooler | 9.3 | 16 | 20 | 19 | 0 | 4 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
How to choose the best electric cooler for ice fishing
Compressor, thermoelectric or ice
The Dometic is the only compressor pick, with a stated range of -7 to 68 degrees F that reaches true freezer temperatures. The Ivation is thermoelectric, holding drinks at 40 degrees F and hot food at 130 degrees F. The COHO is not electric at all: it is an insulated ice chest with 7 days of ice stated. Among the more options, the Nouva, TopAutoGear, Garvee and Wagan are all thermoelectric. If you need frozen bait, the choice narrows to one.
Match capacity to the crew
Stated capacity runs from 18 quarts to 165 quarts. The Dometic holds 37L with room for 48 cans per the bullets, the Ivation holds 48 quarts with about 60 cans per the bullets, and the COHO holds 165 quarts with up to 90 cans. The two Koolatron picks are the compact end at 26 and 18 quarts. The COHO listing recommends a 2:1 ice-to-contents ratio, so plan ice space accordingly. See our best electric cooler for fishing guide for more fishing picks.
Power it from the truck or the wall
The Dometic runs on 12/24V DC and 100-240V AC with no internal battery, and its 3-stage battery protection monitors vehicle battery draw. The Ivation includes a 110V AC home cord and a 12V car adapter. Both Koolatron picks are 12V. The Wagan more option runs on 12V with an optional AC adapter sold separately. See our best 12V cooler for van guide for more 12V options.
Read the warranty line
Coverage varies. The Dometic states 2 years, the Ivation 1 year, and the COHO a lifetime description. Among the more options, the Nouva states 1 year, the Garvee 30 days, and the Wagan a 1-year limited term; the TopAutoGear and Igloo listings state no concrete term. A stated term is worth weight when two picks are otherwise close. See our electric cooler vs mini fridge guide for the format question.
| Cooler | Capacity | Cooling |
|---|---|---|
| Dometic CFX2 37 | 37L | Compressor |
| Ivation 48QT Cooler | 48 QT | Thermoelectric |
| COHO 165QT Cooler | 165 QT | Ice |
| Koolatron D25 26QT Bag | 26 QT | Not stated |
| Koolatron 18QT Cooler | 18 QT | Thermoelectric |
Sizing Notes
- Match capacity to the crew: the picks state 37L, 48QT, 165QT, 26QT and 18QT.
- The Dometic has no internal battery, so plan 12/24V DC or 100-240V AC power at the site.
- The COHO listing recommends a 2:1 ice-to-contents ratio, so plan ice space accordingly.
- The Ivation’s 15.4 by 22.1 by 16.4 inch size needs a flat spot in the truck bed or back seat.
