OPERATING DEVICES USING THE PORTABLE POWER SUPPLY

IMPORTANT!
Always make sure that your end device is compatible with the portable power
supply. Check the user manual for your device as well as the technical data in this
manual. Always select the recommended connection option.
NOTE:
Before connecting an end device, check that the portable power supply is sufficiently
charged. If necessary, charge the battery in the portable power supply (see "Charging
the built-in battery").
1. Press the on/off switch (9) for approximately 5 seconds to switch on the portable power
supply. The colour display will light up together with the function indicator, and the power
data will be displayed.

POWER SUPPLY WITH DIRECT CURRENT (DC)

Cables with a matching plug can be connected to one of the two DC 5.5/2.1mm sockets (6)
to power an end device.
1. Connect the cable on the desired device to one of the sockets.
2. Press the on/off switch (9) for approximately 5 seconds. The corresponding function
indicator will light up. The connected end device will be supplied with power.
NOTE:
The 12V DC output voltage ranges between 9V–12.6V; the maximum output current
is 10A. The DC output voltage decreases in line with the battery charge due to the
chemical properties of the battery. If your device does not have a built-in stabilization
function for the input voltage, it may power off if the input voltage is too low. If this
occurs, disconnect your device and recharge the portable power supply.
Short circuit/surge protection: If the DC output is short-circuited or overloaded, the
device switches off in order to protect the internal components. If this occurs, rectify
the problem and then charge the device to restore functionality.

VOLTAGE SUPPLY WITH ALTERNATING CURRENT (AC)

Cables with a matching Euro mains plug can be connected to the 230 V/AC socket (3) to
power an end device (e.g. bedside light).
