Bars are scaled to the larger of the two figures, so a longer bar means a bigger number — on weight and switchover, smaller is better. A dash means the figure is not published for that model. Cycle counts are the manufacturer’s figure to 80% capacity. Port counts and per-port wattages are the 230–240V variant figures; check the plate on the unit before wiring anything permanent. Both units ship in Malaysian specification: 240V / 50Hz, Type G.
Which should you buy?
DELTA Pro Ultra carries more and costs more. DELTA Pro 3 is the answer when the budget is the constraint.
EcoFlow DELTA Pro 3
Buy the DELTA Pro 3 if the budget is the constraint and the essentials are the job.
See the ModelEcoFlow DELTA Pro Ultra
Buy the DELTA Pro Ultra if the load list keeps growing — headroom is cheaper bought once than twice.

Work backwards from the load instead. Tick the appliances and the hours, and we name the smallest unit that clears both.

Reading a spec sheet honestly
Four questions that settle most comparisons faster than the numbers do.
Capacity or output — which matters more?
Output decides whether the appliance runs at all; capacity decides how long. A 1.5HP air-conditioner needs the watts first, so check AC output against your biggest load before you look at Wh.
Does expandability replace buying bigger?
Often, yes. An expandable unit lets you buy the inverter once and the batteries later, which is why DELTA Pro 3 outsells units of similar capacity that cannot grow.
Why does switchover time appear at all?
Because a router, a NAS or a CPAP notices a 30-second gap and a 20-millisecond one differently. If the unit is for backup rather than camping, this row is the one to read.
Are the dashes hiding bad numbers?
No — they are figures EcoFlow does not publish for that model in this market. We would rather leave the cell empty than fill it with an estimate you might buy on.
