About the Polymer Li-Ion battery pack:

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

  • One 70W 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 types of Laptop computers available
  • You can plug the DC-DC regulator into the car lighter and run the laptop computer directly without the battery 
  • 5  detachable plugs are included and Dell plug is optional, which can connect via cable from the battery pack or regulator, to the laptop computers or other electronic device such as PDA, CD Player and MP3.
  • Please check the plug's diameter of your laptop computer before you

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 positive pole to the center. If the negative is needed in the center, please reverse the plug with the "-" inscription aligned to the "TIP".
