Dell 331-1347 is a 240 W AC adapter for laptop charging. Its 19.5 V output and three-pin, 7.4 mm connector describe the power rating and connection to the laptop, helping check whether they match the device’s requirements.
The listing associates this variant with reference 0FWCRC, which can help distinguish it alongside Dell part number 331-1347. It specifies a C14 power cord, but the cord is not included. The adapter therefore needs a separate cord for connection to mains power.
Use it as a laptop power supply only where the listed electrical characteristics and connector match the laptop. The 240 W rating and 19.5 V output define the stated power provision; the three-pin, 7.4 mm connector identifies the output interface. The C14 detail refers to the separate mains cord.
