  Product Description
The Mestic MCC-50 compressor cool box gives you proper cooling and freezing down to -18°C, which means it'll work fine even when you're parked up in 35°C heat. It's got a 50-litre capacity that'll take standard 2-litre bottles standing upright, plus enough room for several days' worth of food for a family of four. You can run it off your vehicle's 12V or 24V supply using the included car charger, or plug it into mains power with the 230V adapter that comes in the box.

The LCD display lets you set temperatures anywhere between -18°C and +10°C, and there's a Mestic app that connects via Bluetooth or WiFi so you can adjust settings from inside your caravan or tent. The app's handy for checking battery drain when you're running it off 12V overnight. There's also a USB port built in for charging phones, and interior lighting so you're not rooting around in the dark. At 17.7kg it's not exactly lightweight, but the recessed handles make it manageable for two people to shift between vehicle and pitch.

One thing to watch is that compressor cool boxes draw more power than thermoelectric models, so you'll need a decent leisure battery setup if you're planning to run it off-grid for extended periods. The eco mode helps, but you're still looking at monitoring your battery capacity carefully during multi-day wild camping trips. It's a proper bit of kit for anyone doing longer tours or needing reliable refrigeration in hot climates, rather than weekend campers who might get away with a cheaper passive cool box.

Frequently Asked Questions

What's the difference between a compressor cool box and a thermoelectric cool box?
Compressor cool boxes like the Mestic MCC-50 use refrigerant gas and a compressor motor to actively cool, which means they can reach freezing temperatures down to -18°C regardless of outside temperature. Thermoelectric cool boxes only cool 15-20°C below ambient temperature, so if it's 30°C outside they'll only reach about 10-15°C inside. Compressor models draw more power but provide genuine refrigeration and freezing capability that thermoelectric units cannot match.
How much power does the Mestic MCC-50 draw from a 12V leisure battery?
The MCC-50 draws approximately 45W when the compressor is running, which equals roughly 3.75 amps from a 12V supply. The compressor doesn't run continuously - it cycles on and off to maintain temperature. In eco mode on a warm day you might see 20-30 amp hours consumption over 24 hours, while in hot conditions with frequent door opening this could increase to 40-50 amp hours. A 100Ah leisure battery would typically run this cool box for 24-36 hours before needing recharge, depending on ambient temperature and usage patterns.
Can the Mestic MCC-50 be used while driving?
Yes, the MCC-50 connects to your vehicle's 12V or 24V supply via the included car charger and can run while driving. The compressor cool box should be secured properly to prevent movement during transit. Most users connect it to a 12V socket that remains live when the engine is running. For motorhomes and campervans, it's common to wire the cool box directly to the leisure battery system with appropriate fusing so it can run both while driving and when parked up.
What can you actually fit in a 50 litre cool box?
The Mestic MCC-50's 50 litre capacity holds approximately 70 standard drink cans, or a combination of food and beverages for a family of four for 3-4 days. The interior dimensions accommodate 2 litre bottles standing upright, which is useful for milk and soft drinks. You could fit roughly 15-20 meal portions plus drinks, or use it as a dedicated freezer for ice cream, frozen meals and ice packs. The layout works well for stacking items, though remember that compressor cool boxes work most efficiently when not packed completely full as air needs to circulate.
Does the Mestic app require constant internet connection?
The Mestic app connects to the MCC-50 via Bluetooth when you're within roughly 10 metres, which doesn't require internet connection. The WiFi connection option lets you control the cool box remotely when both your phone and the cool box are connected to the same WiFi network, useful in larger motorhomes or when the cool box is in a caravan awning. You don't need mobile data or internet to use the basic app functions via Bluetooth, making it practical for off-grid camping locations.
How long does it take the MCC-50 to freeze items from room temperature?
Starting from 20°C ambient temperature, the MCC-50 will typically reach 0°C in 30-40 minutes when empty, and full freezing temperature of -18°C within 90-120 minutes. If you're loading warm items, expect longer cool-down times - a full load of room temperature food and drinks might take 4-6 hours to properly chill. Pre-cooling items in a domestic fridge before loading them into the cool box significantly reduces power consumption and speeds up the process. The compressor works harder in hot ambient temperatures, so cool-down times increase when it's sitting in direct sun or in a hot vehicle.
Will the MCC-50 drain my vehicle's starter battery?
If you plug the MCC-50 directly into a standard 12V socket that's connected to your starter battery and leave it running when the engine is off, yes it will eventually drain the battery. Most modern vehicles have 12V sockets that cut power when the ignition is off to prevent this. For extended use when stationary, you need to either run it from a separate leisure battery system, use the 230V mains adapter when on hookup, or install a split charge system that isolates the starter battery. The cool box itself has no battery protection circuit, so it'll keep running until the power source is depleted.
Is the Mestic MCC-50 suitable for permanent installation in a campervan conversion?
The MCC-50 works well as a portable cool box in campervan conversions rather than a permanently fixed installation. At 68.2cm long and 17.7kg, it's designed to be moved between vehicle and campsite, with recessed handles for carrying. Many converters prefer slide-mounting systems or built-in drawer fridges for permanent installations. However, the MCC-50 suits layouts where you want flexibility to remove the cool box for cleaning, or to use it separately from the vehicle. The 12V connection would need proper wiring through your leisure battery system with appropriate fusing rather than relying on a cigarette lighter socket for long-term use.
