Standard machines are rated 220–240V~ at 50/60Hz. Total power is 2200W on the M5A and M8A and 2000W on the JM9A. The induction heater in all three is 1200W; the remainder supplies the water pump, controls, and display.
For markets outside the 220–240V range, voltage is configured at 110V–220V to order. Plug type, cord length, and cord rating follow the destination market rather than the Chinese standard. Circuit capacity is sized against the configured total power, not the 1200W heating figure.
The three models differ in how they take water. The M5A and M8A accept either a water purifier or bottled water. The JM9A needs a purifier rated at 600 gallons or above, or one with a pressure tank, plus a negative-pressure valve between the purifier and the machine. Bottled water does not pass through a purifier and does not trigger that requirement.
Water for all models is filtered or bottled. Untreated tap water and well water are not used.
