Which is Best For You? Compressor vs Thermoelectric Coolers
Thermoelectric Coolers
Great for short trips, Thermoelectric coolers are lightweight, inexpensive, and versatile. They keep the temperature of stored items 30-40°F lower than the room temperature using the Peltier effect. This is ideal for on-the-go consumption of drinks or perishables.
They are not very useful during the summer season and are best for overnight trips or areas with mild temperatures.
Compressor Coolers
Perfect for long trips, off-roading, or any journey that requires consistent cooling, compressor coolers work like mini fridges and allow proper refrigeration as well as freezing. Their ability to keep set temperatures regardless of external heat makes them great for perishables such as meat, dairy, or even medications.
When it comes to trunk-limited travel, a dual-zone mini compressor cooler is revolutionary. It allows for simultaneous refrigeration and freezing while occupying the same space.
Top Features to Look for in a Compact Electric Cooler
If you are choosing the best electric cooler, especially for your car trunk, here are some essential features:
Carrying and Layout
Try to find models with detachable lids and a vertical or narrow silhouette. Side handles and wheels are nice to have, but because space is limited, compact size takes priority.
Some brands have introduced slide-in style coolers that fit seamlessly behind the rear seats or beside luggage without intruding into legroom or seatbacks.
Energy Efficiency
Most road trippers face the challenge of cooling their items while on the go. Choose lower power consumption coolers with smart battery protection. Features like automatic shutoff when battery voltage drops too low can help preserve the vehicle battery.
A 12V cooler with adjustable settings will maintain a below-average internal temperature with excellent insulation even during idle periods.
Digital Temperature Control
With innovative electric features becoming common, nowadays coolers have LED displays and touch interfaces. Advanced models allow setting specific temperatures, some up to -4°F. This is very helpful while storing delicate items or when drinks and food require different temperature zones.
Through a mobile app, one is able to control the Bluetooth-enabled models. These models further provide means to control them remotely.
Silent Operation
While nobody wants a device humming away during the ride, some premium devices make sure they stay below 40 decibels, making them effectively quiet. Like all compressor coolers, these too will make noises, but with such protective measures enforced, one will not even notice their presence.
These models really aid in ensuring vehicles do not become distracting and aid in focus on the road during night rides.
Personal Insight: What I’ve Learned After 10,000 Miles with a Compact Electric Cooler
During my month-long trip in America’s southwest, I brought along a dual-zone electric cooler. Since I only had 12 inches of truck space next to our sleeping area, I needed something compact outback.
While using a scant 45 watts, the cooler was able to not only run continuously during the trip, but also keep essential perishables like milk, eggs, and freeze-dried berries at a cool temperature. When paired with a small lithium battery and solar panel, it went for 72 hours without needing to be used.
Knowing digital temp control and a low profile design really allows one to perform is essential while traveling is a blessing. Over the course of our journey, there was an average temperature of 30°F in the morning and 100°F in the afternoons.
