Capacity and layout
On paper the boxes are almost the same size: 46 L for the Dometic, 45 L for the BougeRV. The difference is how that volume is organised. The CFX3 45 is a single compartment, so the whole box is either a fridge or a freezer. The CRD45 is split into two compartments with independent temperatures. If you shop every few days, a single zone is simpler and roomier for bulky items. If you're off-grid for a week and want frozen meat plus fresh food, dual zone wins.
Power and connectivity
Dometic lists 12/24 V DC and 100–240 V AC inputs with cables supplied. BougeRV lists a 60 W rated input with an Eco mode under 45 W. Real daily consumption depends on ambient temperature, set point, insulation of the space around the fridge and how often you open it – so treat any single figure as a starting point and plan your battery with headroom.
Support and ecosystem
Dometic is one of the largest RV-appliance makers, with service partners in many countries – a meaningful advantage if something fails mid-trip. BougeRV sells mainly online with a 2-year warranty according to its product page. Public owner reviews for both are broadly positive; recurring themes for any portable compressor fridge are lid seals, slide mounting and ventilation around the compressor.
