  • Design

    Aesthetically, the Knox Electric Cooler is a nice looking unit with a blue body, white lid and side carrying handles which is a pleasing alternative to the plain beige colors we often see on portable coolers.

    The unit is sturdily built with solid plastics that give it a feeling of robustness. The lid features a locking mechanism which is designed to ensure the lid stays sealed tightly to maintain a consistent internal temp for the chamber.

    Size-wise, the unit has an external size of 22 inches length, 15 inches wide with a height of 16 inches. This makes it compact enough to fit it in the trunk of a car for convenient transportation.

    Easy Transportation

    Functionally, it wins top marks for its high portability. The unit weighs in at only 14.4 lb, making it a lightweight in the portable cooler crowd. The double handle design includes a sizeable ergonomic carry handle that extends out, a small pull handle and easy transport wheels. This ensures that one person can comfortably transport the unit whether you want to pull it along as you walk over short distances or carry it by lifting it up.

    Dual Voltage

    The dual voltage design allows you to power the unit from an AC or DC power source, giving you the flexibility to use it at home or on the road.

    It includes two built-in power cords; a 58″ power cord for 110V AC home use and a 67″ 12V DC car adapter which both come pre-attached for your convenience. Disappointingly, the cords are rather short so you need to keep the cooler nearby a power outlet unless you use an extension lead. However, the DC cord is still long enough to reach the back seat in a 5 seater vehicle so this should only be an issue for larger vehicles.

    Accessing the power cords is made easy thanks to the handy built-in plug storage compartment in the lid which can be conveniently accessed by turning one of the two plastic covers and removing it.

    Knox Electric Cooler and Warmer Features


    This cooler/warmer has a good sized interior capacity of 48 quart which provides enough space for approximately 60 cans or 6 two-liter soda bottles and 15 cans. It includes a removable compartment divider that can be placed in one of two slots which gives you two separate compartments for storage organization.

    Cooling/Warming Functionality

    The Knox can be used as both a cooler and a warmer, giving you dual functionality to keep food and beverages chilled or keep hot foods warm. The cooler can chill to 40°F below ambient temperature without requiring ice, saving you interior storage space. The warmer can heat up to 130°F temperature.

    Knox have kept things simple in terms of operating the unit. There is a small switch that allows you to alter between COLD/OFF/HOT for easy operation. The hot/cold ready indicator light gives you a handy indication when the interior has reached the desired temperature.

    The Knox Electric Cooler and Warmer triumphs for value, making it a great choice for the budget conscious looking for affordable, lightweight portable cooler/warmer that is ideal for use when travelling.

    Its ease of portability, dual voltage design and built-in power cord storage are its stand out features that make it flexible for many different situations. It is also energy efficient due to its low power draw which is an advantage particularly if you’ll be using it in a vehicle.

    While there have been some complaints from consumers about the unit breaking within 1-2 months of ownership, Knox Gear has excellent support should you need a replacement.
