Power adapter for 12 V devices
The Shenzhen Kaifa FJ-SW1201200D delivers a steady 12 V at 1200 mA for equipment that matches this voltage and current requirement. It includes a power cord and terminates in a 5.5×2.1 mm barrel connector. Buyers whose hardware needs a different voltage, a higher amperage or an alternative connector type cannot use this unit.
Worldwide input range and protection limits
The adapter accepts 100–240 V at 50–60 Hz with a 1.5 A input rating, so it works on mains supplies across most regions without a separate voltage selector. Built-in safeguards protect against incorrect voltage, short circuit and internal overheating, but the 14 W maximum output caps the power available to the connected device.
Simple barrel-plug installation
Plug the supplied cord into the adapter, insert the 5.5×2.1 mm jack into the device and connect to mains power; no driver or configuration is required. The most common issue is a polarity or size mismatch at the device socket, so verify the connector specification before ordering. Cosmetic marks on the casing do not affect electrical function.

Questions about this item
Should I choose the 12 V 1200 mA version or a different capacity?
Choose this adapter only when your device specifies 12 V and a current draw of 1200 mA or less; the output is fixed at those values.
What does the 12 V 1200 mA rating mean once the adapter is connected?
It delivers a steady 12 V up to 1200 mA, providing a maximum of 14 W to the connected device.
What connector standard does the 5.5 x 2.1 mm plug follow and what does it limit?
The 5.5 x 2.1 mm barrel connector is a common centre-positive standard; it limits use to devices that accept that exact plug size and polarity.
