THIS COOLBOX USES COMPRESSOR TECHNOLOGY
What is the difference between the cooling technologies? ABSORPTION COOLING Details of distinguishing features:
Gas-powered cooling independent of electricity
Three way cooling – Gas, 12 volts DC or 230 volts AC
Silent operation
Cooling performance depending on the ambient temperature
The Technical Bit A concentrated ammonia solution is heated in a boiler and expelled as vapour. The pressurised ammonia gas is then liquefied in a condenser. Supplied with hydrogen, it evaporates and in the process extracts heat from the storage container. The ammonia gas then enters the absorber where it is reabsorbed in a weak solution of ammonia. Finally, the saturated solution flows back to the boiler where the whole cycle starts again.
THERMOELECTRIC TECHNOLOGY Details of distinguishing features:
12 / 24 / 230 Volt
Independent of inclination
Lightweight and low-cost
Cooling performance depending on the ambient temperature
The Technical Bit The thermoelectric principle was discovered by J. C. A. Peltier, which is why the temperature generating parts of thermoelectric systems are referred to as Peltier elements. Thermoelectrics are based on the fact that cold or heat energy (depending on the polarity) is generated when a DC current is conducted between different types of metal. The heating or cooling capacity is further enhanced by heat exchangers and air fans. Ideal for low and medium cooling volumes.
COMPRESSOR TECHNOLOGY Details of distinguishing features:
Excellent cooling performance even at extreme ambient temperatures
Refrigeration and deep-freezing
12 / 24 / 100 – 240 volts
Low power consumption – suitable for solar operation
Battery protection
Quiet operation with little vibration
Independent of inclination
The Technical Bit Compressor units operate using a refrigerant that changes from liquid to gaseous state in the evaporator. The evaporation extracts heat from the interior of the cooling unit – the temperature drops. The compressor draws in the refrigerant, compresses it and passes it on to the condenser. Here, the absorbed heat is released to the atmosphere. The refrigerant liquefies again and flows to the evaporator, where the cycle begins again.
Frequently Asked Questions
Why does a compressor cool box cost more than thermoelectric models?
Compressor cool boxes use genuine refrigeration technology with a sealed refrigerant system, similar to your kitchen fridge. This allows them to reach freezing temperatures regardless of outside heat, whereas thermoelectric models can only cool about 20°C below ambient temperature. The compressor system includes more complex components including the compressor motor, condenser, evaporator and refrigerant circuit, which increases manufacturing costs but delivers superior cooling performance and lower energy consumption over time.
Can the Mestic MCC-25 run continuously on a 100Ah leisure battery?
Compressor cool boxes typically draw 45-60 watts when actively cooling, cycling on and off to maintain temperature. On a 100Ah leisure battery, the MCC-25 would draw roughly 4-5 amps per hour while running. With the duty cycle averaging 30-40% in moderate conditions, expect 20-30 hours of runtime on a fully charged 100Ah battery. The eco mode extends this further by allowing slightly wider temperature tolerances. Battery protection circuitry automatically shuts down the unit before your battery voltage drops too low to start your vehicle.
What is the difference between absorption and compressor cool boxes for caravanning?
Absorption cool boxes run on gas, 12V or 230V and operate silently with no moving parts, making them popular for static caravanning. However, they only cool 25-30°C below ambient temperature and must sit perfectly level to work properly. Compressor cool boxes like the Mestic MCC-25 reach true freezing temperatures even in 35°C heat, work at any angle, and use less battery power. Absorption models suit caravanners who stay on one pitch with gas available, while compressor units suit tourers, motorhomes and those wild camping who need reliable freezing capability from battery or solar power.
How long does the MCC-25 take to freeze items from room temperature?
Freezing time depends on the starting temperature of your items and ambient conditions. Pre-chilled food from your home freezer stays frozen within an hour of the unit reaching -18°C. Room temperature items take considerably longer, typically 4-6 hours to freeze solid. The most efficient method is pre-cooling the empty unit overnight, then loading already-chilled or frozen items before your trip. This reduces the thermal load and maintains temperatures with minimal power consumption. The dual compartments let you keep frozen items separate from fresh food that only needs chilling to 4-6°C.
Will the compressor noise disturb light sleepers in a campervan?
Modern compressor cool boxes run quieter than older models, but you will hear the compressor motor cycle on and off. The MCC-25 produces approximately 45 decibels when running, similar to a quiet conversation. Once the unit reaches your set temperature, the compressor cycles off and stays silent until the temperature rises enough to trigger cooling again. In well-insulated conditions this might be 15-20 minutes of silence between short 3-5 minute cooling cycles. Placing the unit on a rubber mat reduces vibration transfer. Some users position the cool box in a vehicle's boot or storage area away from sleeping quarters, though the 250cm cable provides flexibility.
Can you use the USB port to charge devices while the cool box is running on 12V?
The USB-C port functions independently of the cooling system and works on all power sources including 12V, 24V and 230V. You can charge phones, tablets or other USB devices simultaneously while the compressor operates. The port typically outputs 5V at 2.1A, providing standard charging speeds for most devices. This eliminates the need for separate 12V USB adapters in your vehicle. However, when running the cool box from battery power without the engine running, charging multiple devices increases total power consumption and reduces how long your leisure battery will last.
What size solar panel do you need to run the Mestic MCC-25?
A 100-watt solar panel generates enough power to run the MCC-25 during daylight hours in summer conditions, with excess capacity charging your leisure battery for night-time operation. Factor in the compressor's duty cycle averaging 30-40% runtime, which means it draws power for roughly 7-10 hours equivalent across a 24-hour period. A 100Ah lithium leisure battery paired with 100-200 watts of solar typically provides sufficient capacity for continuous operation in spring through autumn. Winter camping or heavily shaded pitches may require larger solar arrays or supplementary charging from your vehicle alternator or hookup power.
Does the MCC-25 need special maintenance or servicing?
Compressor cool boxes are sealed systems that require minimal maintenance. Keep the condenser vents clear of debris and wipe down the exterior and interior surfaces regularly. Avoid storing the unit in damp conditions when not in use, as moisture can affect electrical components. The compressor and refrigerant circuit are sealed for life and should not need regassing like older portable fridges. If cooling performance drops significantly, check the condenser fan is running and vents are not blocked. Most issues relate to power supply problems rather than the cooling system itself. Store the unit with the lid slightly open to prevent mould growth during extended periods of non-use.
