Using myPower ALL
myPower ALL can be used to power and/or charge your portable device. With devices that require
higher voltage levels, like notebook computers and portable DVD players, we recommend that you use
myPower ALL only to power the device. You will find that powering without charging your higher voltage
device will maximize the battery life of myPower ALL, thus letting you use your portable device even
longer.
To use myPower ALL to power and/or charge your device, take these steps which are described in detail
in the following sections.
• Select an adapter plug and connect the plug to the output cord.
• Connect the power output cord to myPower ALL.
• Adjust the voltage level to match that of your device and lock the voltage setting.
• Connect the adapter plug/output cord to your device.
Select/Connect the Adapter Plug
1. Select the adapter plug that fits securely into the power jack on your portable device.
2. Locate the polarity symbol on your device in the area around the power connector jack:
The polarity of your device determines how you will connect the power output cord to the adapter
plug to connect to your device.
