Purchasing Guide: Factors to Take Into Account When Choosing the Best Thermoelectric Cooler


Indicated thermoelectric capacity is in quarts or liters. It is best to completely pack the cooler in order to maximize energy efficiency. Choose the appropriate thermoelectric cooler size based on how much food you plan to bring. The full-size electric coolers have a capacity of 40–50 liters, which is typically on the smaller side.

Door Positioning

Most thermoelectric coolers have a top door, a side door resembling a mini-fridge, or both. Generating more access and packing flexibility is the top opening door orientation.

Number of shelves or dividers

Some thermoelectric coolers come with shelves and dividers, while others don't. Foods of various types can be divided using dividers. Regarding the quantity, kind, and positioning of the shelves or dividers, pick what works for you.

Energy Rating

Because these electric coolers need a reliable power source to function, you should make sure you have access to the recommended power source. The majority work with 110V AC or 12V DC power sources. Some devices can also be powered by solar panels.

Greater cooling efficiency is provided by coolers with higher power ratings. But they need a more potent source of power. Avoid overdrawing the battery if you're using your car as a power source.

Added Benefits

  • Thermostatic management You can program a thermoelectric cooler with a thermostat to operate at a specific temperature. Accordingly, the cool box will turn on or off to maintain the desired temperature. Depending on changes in the ambient temperature, this feature enables you to conserve energy.
  • Drain drug For ice coolers, this feature is essential, but not as important for thermoelectric coolers. However, it greatly simplifies cleaning the electric cooler.
  • Warming/heating mode You can use the warming feature of some electric coolers to keep your food warm by simply flipping the polarity of the power plug.
  • In frozen state If you intend to bring along some highly perishable foods for an extended period of time, this is a crucial feature.

The Best Thermoelectric Cooler Buying Guide

  1. Identify the essential characteristics you desire in a thermoelectric cooler. How big would you need? Decide on the number of shelves, door orientation, and any other features that you prefer.
  2. Establish a budget. Determine your price range for a thermoelectric cooler. Examine the price range for various coolers with the features you desire and choose those that fit within your spending limit.
  3. Verify the brand's and potential products' reputations. You should choose well-known brands from among the many available ones on the market. Examine the company's ratings and reviews as well as those for the particular products you are considering.
  4. Make a decision. After eliminating a few options that meet your criteria for features, price, and reputation, choose one of those options.


The most frequently mentioned drawback of thermoelectric coolers is that food is not sufficiently cooled or heated, depending on the case. To get the food cold, keep in mind that the cooler is not intended to function as a freezer or refrigerator.

However, you can pre-chill or pre-warm the food to increase its effectiveness. Additionally, with prolonged use, the plug on most of them tends to overheat. As long as it complies with the manufacturer's power rating and recommended power sources, you could replace the plug in this situation with one of higher quality.
