Fridge, Coolers & Accessories

Fridge or cooler

A conventional cooler depends on ice, so it is simple, needs no power and works anywhere, but ice melts, takes space and makes food soggy. A portable fridge-freezer runs on 12-volt DC power from the vehicle, can hold a set temperature, and often has a compressor like a household fridge. Many models also run from 120-volt household power, which is useful for pre-cooling before a trip. For multi-day trips, a fridge reduces the need for resupply, while a high-quality cooler may be enough for weekends.

What to compare

• Capacity: Listed in liters or quarts. Think about how many people and days, and the space in your vehicle.
• Single or dual zone: Dual-zone units can freeze one side and refrigerate the other.
• Power draw and battery protection: A fridge needs a dependable power source. Look for a low-voltage cutoff that protects the starting battery.
• Insulation and construction: Thicker insulation and sturdy latches matter for coolers and fridges alike.
• Mounting: Solid mounts, slides and tie-downs keep the unit from moving in a hard stop.

Power planning

A compressor fridge cycles on and off, so average consumption is lower than its running draw, but it still adds up over days. If you plan to run it with the engine off, think about a dual battery or a portable power station, and use appropriately sized wiring with a fuse. Make sure the vehicle's 12-volt outlet is rated for the fridge's current.

Use and care

Pre-chill the fridge and its contents before leaving. Leave air gaps around vents so the compressor can shed heat, and keep the unit level and in the shade. Secure it so it cannot become a projectile in a crash or on rough terrain. Clean the interior, dry it and leave the lid slightly open during storage to prevent odors. Always check the manufacturer's specifications for operating angle and temperature range.

Think about the supporting gear. A sturdy cover protects the fridge from sun and dust, a cable with a secure plug avoids power drops on bumpy roads, and a few reusable ice packs in a basic cooler extend cold time between refills. Keep the fridge away from direct sun and heat sources to ease the compressor's workload.

Choosing capacity and keeping food safe

Estimate food needs per person per day, then add space for drinks and a buffer. A fridge should be kept about two thirds full for efficient cooling, since empty space warms quickly when the lid opens. Pack items you need most often on top, and use baskets or dividers to keep things organized.

• Keep raw meat sealed and below ready-to-eat food.
• Use a thermometer to confirm food remains at safe temperatures.
• Choose a unit that fits through your cargo opening and can be lifted by two people when full.

Hard coolers rely on insulation thickness and gasket quality. Pre-chilling the cooler and using block ice, which melts more slowly than cubes, helps extend cold time. Keep coolers out of direct sun, covered with a blanket or in a shaded spot, to reduce ice melt and compressor load.
