  Product Description
The myCOOLMAN 110-240V Mains Power Block lets you run your portable fridge from household AC power instead of draining your vehicle's 12V battery. This AC to DC adapter accepts 110V-240V input and delivers a stable 6.0A DC output, making it suitable for myCOOLMAN CCPR and MCMR recreational fridges as well as most other DC-powered portable fridge brands. When you're at home preparing for a trip or staying at a campsite with mains hook-up, this power block keeps your fridge running without touching your leisure battery.

Why do I need a mains adapter for my portable fridge?


A mains adapter converts 240V household power to 12V DC, allowing your portable fridge to run indoors or at campsites with electrical hook-ups without draining your vehicle or leisure battery. The myCOOLMAN power block outputs 6.0A DC and works with universal voltage (110V-240V), making it compatible with most DC portable fridges including myCOOLMAN CCPR and MCMR models.

The universal voltage input (110V-240V) makes this adapter useful for international travel, whilst the 6.0A output provides enough current for compressor fridges to maintain temperature efficiently. It works as a replacement or spare for your existing AC adapter, and the DC output connects directly to your fridge's 12V power socket. Caravanners and motorhomers often keep one at home for pre-cooling food before departure and another in the vehicle for site use.

For anyone running a 12V compressor fridge in a caravan, motorhome, or campervan, having a dedicated mains adapter means you're not constantly swapping cables between AC and DC power sources. The power block eliminates the need to run your fridge from battery when stationary, extending your off-grid capacity for when you need it. It's particularly useful for weekend campers who arrive Friday evening and want to preserve battery for the days ahead.

Frequently Asked Questions

Will this myCOOLMAN power adapter work with my portable fridge brand?
The myCOOLMAN 110-240V mains power block is designed for myCOOLMAN CCPR and MCMR portable fridges but works with most DC-powered portable fridge brands that accept 12V DC input. The 6.0A output is sufficient for standard compressor fridges, though you should check your fridge's power requirements. Many portable fridge brands use similar DC power connections, making this adapter a versatile option for caravan and motorhome owners who need mains power capability.
What voltage does this AC adapter output for my 12V fridge?
This adapter outputs 12V DC at 6.0 amps, which is the standard voltage for portable 12V compressor fridges used in caravans and motorhomes. The input accepts 110V-240V AC mains power, making it suitable for UK homes (240V), European campsites, and international use. The 6.0A current rating provides adequate power for most portable fridges to maintain cooling performance when connected to mains electricity rather than battery power.
Can I leave my portable fridge plugged into this mains adapter permanently?
Yes, you can leave your portable fridge connected to the myCOOLMAN mains power adapter continuously when you have access to AC power. This is common practice for motorhomers and caravanners at sites with electrical hook-up, or at home when pre-cooling the fridge before departure. Running your fridge from mains power via the adapter is more efficient than using battery power and eliminates concerns about battery drain. The adapter provides stable 12V DC power suitable for extended use.
Do I need this mains adapter if my fridge already has AC and DC sockets?
If your myCOOLMAN fridge has both AC and DC sockets built-in, it already contains internal circuitry to convert mains power to DC, so you wouldn't need this external adapter for that model. This mains power block is designed for DC-only portable fridges (like some CCPR and MCMR models) that don't have built-in AC capability. It's also useful as a replacement if your original AC adapter fails or as a spare to keep at home whilst your main adapter travels with the fridge.
What's the difference between running my fridge on mains power versus 12V battery?
Running your portable fridge from mains power through an AC adapter draws electricity from the campsite hook-up or household supply rather than depleting your vehicle or leisure battery. This preserves battery capacity for when you're off-grid or wild camping without electrical access. Mains power provides unlimited runtime without battery monitoring, whilst 12V battery operation is essential when travelling or camping away from hook-up facilities. Most caravanners and motorhomers switch to mains when available and use battery power only when necessary.
