• Do not charge the power pack using your PC or the notebook. The charging currents can
damage the USB port of the PC/notebook.
• Only use suitable charging devices or USB connections for charging.
• As a rule, do not charge devices or USB connections that are defective and do not try to repair
them yourself.
• Do not overcharge the product or allow the battery to completely discharge.
• Avoid storing, charging or using the device in extreme temperatures and extremely low
atmospheric pressure (for example, at high altitudes).
• When stored over a long period of time, batteries should be charged regularly (at least every
three months).
• Begin charging the power pack by connecting the included Micro-USB cable to the power pack’s
port (
IN 5V/1A
) and to a suitable USB charger. Please refer to the operating instructions for the
USB charger used.
• Charging begins and ends automatically.
• Charge the Power Pack fully before using it for the first time.
Note – Capacity
• The capacity is always shown when the Power Pack is charging.
• Each status LED corresponds to 25% of the capacity. When an LED is permanently illuminated, this
indicates that this capacity level has already been reached. The Power Pack is charged to at least
75% if three LEDs are illuminated, and the fourth is flashing.
• If all four status LEDs light up, the full capacity is available.
• Press the button of the Power Pack to switch it on and to check its current capacity.
• To switch the power pack off, press and hold the button until the status LEDs go out.
4.2 Charging terminal devices
Warning – Connecting terminal devices
• Before connecting a terminal device, check whether the power output of the charger can supply
sufficient power for the device.
• Ensure that the total power consumption of the connected terminal device does not exceed
1000 mA.
• Please refer to the instructions in the operating manual of your terminal device.
• It is essential that you observe these specifications and the safety instructions regarding the
power supply of your devices.
• The power pack must not be charged and discharged at the same time!
Warning
• Never connect the charging cable of the Power Pack to both the input and the output of the
Power Pack at the same time. This could damage the battery.
• Do not connect any terminal devices while the Power Pack is charging. This could damage the Power
Pack and the connected device.
