Introduction
Thinking about getting a 12V cooler for your campervan, road trip, or camping setup? You’ve probably come across two types: coolboxes and compressor fridges. They look similar, but they work very differently. Let’s break it down so you know which one will actually keep your food and drinks properly cold.
What Is a 12V Coolbox?
A 12V coolbox, also known as a thermoelectric cooler, uses a special electronic plate (called a Peltier plate) to move heat away from the inside. This cools the contents to around 30–40°C below the outside temperature.
That means if it’s 30°C outside, your coolbox might only cool down to around 0–5°C. On a very hot day, that number creeps higher.
Good for:
- Chilling drinks or snacks
- Short trips
- Cooler climates
Not great for:
- Keeping meat or dairy safely stored
- Hot summer days
- Trips longer than a few hours without backup power
What Is a Compressor Fridge?
A compressor fridge works just like the fridge at home. It uses a refrigerant and a small motor to compress and expand gases. That process pulls heat out of the fridge and pushes it outside.
Because of this, compressor fridges can reach and hold true fridge (around 3°C) or even freezer temperatures (-18°C or lower). The outside temperature doesn’t matter nearly as much.
Good for:
- Long trips
- Storing meat, dairy, and fresh food
- Hot climates
- Off-grid setups with solar or battery
Power Use: Which One Is More Efficient?
Coolboxes use a steady stream of power (usually 3–5 amps), even when they’re not cooling hard. There’s no thermostat, so it just keeps drawing power.
Compressor fridges cycle on and off. They only use power when they need to adjust the temperature. Most models have battery-saving modes and can run for 24+ hours off a decent leisure battery or solar setup.
➡️ Verdict: Compressor fridges use power smarter. You get more cooling for less energy in the long run.Real-World Feedback
People who use 12V coolers in campervans or off-grid setups have shared different experiences depending on their needs and where they’ve travelled.
On Coolboxes:
“Our coolbox was great for day trips and kept our drinks nicely chilled on a long drive through Wales.”
“I used a thermoelectric coolbox in the Lake District last spring — it was quiet, light, and perfect for snacks and drinks during hikes.”
“Plugged ours into the car on the way to the beach — everything stayed cool the whole day. For short trips, it does the job.”
On Compressor Fridges:
“I used the Totalfreeze for a full weekend with solar and had no problems. Kept everything cold, even frozen.”
“The coolbox was fine in the UK spring, but struggled in Spain. I switched to a compressor fridge and haven’t looked back.”
Pros and Cons Side-by-Side
| Feature | 12V Coolbox (Thermoelectric) | Compressor Fridge |
|---|---|---|
| Cooling Power | 30–40°C below outside temp | Down to -18°C or colder |
| Power Use | Constant draw (3–5A) | Cycles, low draw (1–4A avg) |
| Food Safety | Not for long-term storage | Safe for all perishables |
| Weight & Cost | Lighter, cheaper | Heavier, more expensive |
| Ideal Use | Day trips, drinks | Long trips, all foods |
Which One Should You Get?
Ask yourself these questions:
Do you need to keep meat or dairy fresh?
→ Get a compressor fridge.
Just chilling some drinks for a day at the beach?
→ A coolbox will do the job.
Travelling through hot weather or off-grid?
→ Compressor fridges handle the heat better and use energy more wisely.
Final Tips Before You Buy
Check your power setup. A compressor fridge works great with solar or a second battery.
Go chest-style if possible. They hold cold air better when you open the lid.
Pick the right size. Bigger fridges use more energy. Don’t get more space than you need.
Look for low-voltage protection. This keeps your battery from draining too far.
Final Word
So, what really keeps things cold? Compressor fridges are the clear winner for serious trips, food safety, and off-grid adventures. But 12V coolboxes still have a place, for light use, day trips, and keeping things simple.
Whichever you choose, make sure it fits your adventure and your setup. And if you’re not sure, we’re always happy to help.
FAQ
Q1: What’s the difference between a 12V coolbox and a compressor fridge?
A 12V coolbox uses thermoelectric cooling and drops temperature based on the outside air. A compressor fridge works like a home fridge and can reach true fridge or freezer temperatures, regardless of ambient heat.
Q2: Can a 12V coolbox keep food safe?
Not always. Thermoelectric coolboxes may not stay cold enough in hot weather to keep meat or dairy safe for long periods. They're best for drinks or short trips.
Q3: Are compressor fridges better for van life or camping?
Yes. Compressor fridges are more reliable in heat, use energy more efficiently, and keep food safe for longer. They're ideal for off-grid and long-term use.
Q4: How much power does a compressor fridge use?
Most compressor fridges use 1–4 amps and cycle on and off, which saves energy. Many can run for 24+ hours on a leisure battery, especially with solar support.
Q5: Are 12V compressor fridges worth the money?
Yes, if you need proper cold storage, especially for longer trips. They cost more than coolboxes, but they offer better performance and energy efficiency.
