Dolphin D-12BTU Inverter Air Conditioner, 12000 BTU

Our review

The Dolphin D-12BTU is a 12000 BTU split air conditioner built around inverter technology, which means the compressor varies its speed instead of switching fully on and off. In practice that gives steadier room temperature and less wasted electricity than a fixed-speed unit of the same capacity, and Dolphin pairs it with an auto restart system that returns the unit to its previous settings after a power cut. That matters in Tanzania, where outages are common. It suits a bedroom, small living room, office or shop counter where one indoor unit can cover the space. Before buying, confirm the room size and ceiling height, check whether your wiring and breaker can carry the load, and decide if you need a qualified installer. Compare against non-inverter 12000 BTU models on running cost, and against larger capacities if the room is open-plan or sun-exposed. Available on Sokonia.
