Benefits of CR50 compressor fridge
No need for external ventilation as the CR50 fridge can be vented each
side of the unit.
Extremely low power usage on 12volt approx 1.5 amps per hour.

Higher tilt tolerance of 45 degrees.
The RM123 fridge can be powered by LPG gas, mains electric or 12 volt.
The 12v should only be used whilst traveling as it would flatten your battery
very quickly if the engine is not running. LPG gas fridges must be vented
externally, allowing the fridge to keep cool. The flue must go directly
outside the vehicle to expel the gas fumes.
RM123 is completely silent.
The CR50 fridge has a compressor, which can be heard whilst running. This
fridge is powered by 12/24 volts, but an additional mains adaptor can be
used so that the CR50 fridge can then be powered by mains electric (hook-up).
If you are plugged into hook-up the adaptor will automatically use mains
electric over 12volt. CR50 is very economical on 12volt and will last nearly
3 days on a 100 amp leisure battery without being recharged. The
CR50 does not need external venting.
