This power pack comes with a 220 Watt-hour super high capacity rechargeable lithium ion battery and a multi output voltages (5v/9v/12v/15v/16v/18v/19v/24v) DC to DC power adapter.

Easy to use: set the DC to DC power adapter comes with the package at the voltage you need, then connect the DC power adapter input end to the battery output port with supplied connection cable, DC power adapter output to your laptop/notebook computer or other devices.

Super long running time: The battery capacity is around 220 Watt-hour. For your info, a 6-cell laptop internal battery capacity is around 50 Watt-hour. This battery may add extra 8 ~ 15 hours running time for most laptop computers. We tested this power pack kit with a 15.4" Screen HP G62 laptop, it added extra 9 hours running time. (This is just for your reference. Actual running time varies, depending on notebook computer's configurations and what kind of applications running . For example, screen brightness, the use of the CPU, the hard drive, the CD drive, and other peripherals results in an additional drain upon the battery, effectively reducing the battery's run-time. The total run-time of the battery is also heavily dependent upon the design of the notebook. To ensure maximum performance of the battery, optimize the computer's power management features. Refer to the computer manual for further instructions. )

The DC to DC power adapter can convert DC power from the battery to many different voltages: 9V/12V/15V/16V/18V/19.5V/24V & a 5V USB port.


The DC to DC power adapter also comes with 8 different interchangeable connector tips that can fit many different electronic devices.
