Whynter FM-45G Review

Performance Comparison

Temperature Control

The Whynter exhibits the most accurate display temperature of any model we tested. On average, it registered just 1.6ºF different from the actual internal temperature. Though it's rated to reach -8º F, we recorded its minimum temperature to be -5.8ºF, which is still no small feat and much colder than most of us will ever actually need.

Though it isn't exceptionally fast at cooling its contents, the Whynter also has a Fast Freeze function that can speed this process up considerably. It's not the absolute best performer in this metric, but the Whynter still holds its own among the stiff competition and does a bang-up job of it.

Insulation

Another high-scoring metric for the Whynter, its thick walls and insulation put it right on par with the best of them at keeping food cold, even when unplugged. It's also a solid piece of equipment, with visibly ultra-thick walls and a super sturdy lid and hinge.

The rubber feet proved to be durable and useful, preventing this cooler from sliding all over the place during transit, while internal baskets help secure your food. Though it's not advertised as being one, we used the Whynter as a seat frequently and never had any doubts that it would hold us without caving.

The drain and plug come in handy for cleaning without seeming to take away at all from the performance of the Whynter.

Energy Consumption

One of just a few coolers we tested with a specific energy-saving power mode, the Whynter is solid when it comes to saving electricity — if you want it to. On its "Low" mode, this cooler uses just 35.5 Watts — one of the lowest power draws among models we tested!

However, this is slightly offset by the regular power mode and Fast Freeze mode, which both use the most energy of any cooler in this review — 65.5 Watts. But if the ambient air temperature is below 90ºF, you can safely use the low power mode to save your battery while still keeping your food chilled.

The Whynter features a low power mode that saves energy while keeping your food cold, and proved to be among lowest power draws in this review.

Ease of Use

We like the design of this trunk-style cooler, and its slightly smaller capacity makes it a bit easier to rifle through. It's one of the only models we tested with two internal baskets that are relatively easy to take out even when stuffed to the brim with cold goodies.

It also has a sturdy latch for the lid that can be locked closed. Advertised as a 45 quart cooler, we measured this unit to be just over 40 quarts and able to hold 58 cans. We are surprised by this small capacity — smaller than two of the much smaller-looking thermoelectric models. The Whynter is also one of the only compressor models we tested that doesn't have an internal light.

Portability

The Whynter is far and away our least favorite model to carry. It's one of the heaviest in our review, at 54.6 pounds, and has tiny little handles with a simple hard plastic grip — not the most comfortable to carry.

It also has very pointed edges and corners, which we think look quite excellent but also are painful to bump against. Its saving grace is the longest DC cord in this review, at 9' 6", allowing you to place the Whynter where you want it and hopefully never have to move it again.

Not the most comfortable carrying handle for a cooler that weighs nearly 55 lbs!

Features

While not a flashy cooler, the Whynter mostly has what you need. It does have a drain in the bottom, which comes in handy for defrosting or cleaning spills.

One thing we really like is that the display shows your battery level, which helps to monitor your energy usage — unfortunately, that display is on the back of the cooler, right next to the plug. A rather unfortunate location, we think. The Whynter is also a relatively noisy model — one of the noisest we tested.

The control panel is located on the right side, just above the plugs.

Value

Costing several hundreds of dollars less than many of the compressor models we tested, the Whynter gives some seriously great performance for what you pay. We think this impressive performance coupled with a fairly reasonable price tag (for this kind of technology and engineering) makes it a very high-value item.

The Whynter allow you to bring things you'd normally leave at home - like eggs.

Conclusion

Offering a fairly great all-around performance (aside from portability), the Whynter has a lot to offer while costing less than several of its competitors. It has an impressively efficient low energy mode, one of the longest DC cords in our review, an excellent minimum temperature, and an overall useful design. Though it is one of our least favorite models to carry and has a smaller internal capacity than claimed, we think the Whynter is a solid powered cooler and for a very reasonable, competitive price.

Have an adventure with your Whynter!
