About DC-DC Regulator with Switch  ( please click here for detailed specs)

  • One 120W DC-DC regulator is included to convert the battery pack  ( 14.8V ) voltage to 15V, 16V, 18V., 19V, 20V, 22V and 24V separately via a switch, as shown in the picture at right
  • The voltage range from 15V- 24V DC will cover most Laptop computers available
  • You can plug the DC-DC regulator into the car lighter and run the laptop computer directly without the battery
  • 6  detachable plugs are included, which can connect via cable from the battery pack or regulator to the laptop computer or other electronic devices such as PDA, CD Player and MP3.
  • Dell plug is optional
  • Please check the plug's diameter of your laptop computer before purchase


connect battery pack to regulator , which will convert output voltage from 15V - 24V



The connector must be plugged into the cord correctly in order to ensure the correct polarity. Most devices are designed to take the positive (+) in the middle and the negative (-) on the exterior of the plug. If unsure you can consult the user manual or look for a diagram on the original AC adapter. 


If the Positive is in the center prong, please align the "+" on the connector to the "TIP" inscription on the cord. This will bring the +pole to the center. If the negative is needed in the center, please reverse the plug with the "-" inscription aligned to the "TIP".
