Operation
Check the internal battery charge level before each use.
Make sure the connection values of your mobile device match those of the product
(see technical data).
The USB cable is not suitable for data transfer.
Remove any protective films from the product.
a) LED indicator of the battery charge level
Press the function button (3) once briefly to check the battery level. The remaining capacity on
the battery level indicator (2) is indicated by the lit LEDs as follows:
1 LED
Remaining capacity up to 25 %
2 LEDs
Remaining capacity up to 50 %
3 LEDs
Remaining capacity up to 75 %
4 LEDs
Remaining capacity up to 100 %
The LED that indicates the current battery level flashes while charging.
b) Charging the battery
• When using for the first time, it is recommended to fully charge the product once.
• Charge the portable charger at the latest when only one LED lights up and/or the battery
level falls below 25 %.
• The charger will be charged via the USB Type-C™ port. To charge the portable charger, a
USB charger (not included) is required. A USB Type-C™ charging cable for connection to the
USB Type-C™ input/output IN/OUT (4) is included.
• Plug the USB Type-C™ connector into the USB Type-C™ input/output. Plug the USB-A
connector of the USB charging cable into a USB-A port of a USB charger. Observe the
technical data.
A USB charger with 3 A is recommended for the portable charger input current. If a
lower input current is used, charging will take longer. However, a higher input current
will not reduce the charging time since the input current is limited.
• The charging time of the portable charger can be up to approx. 5.5 – 6 hours (battery capacity
approx. 20 %) using a USB charger with 3 A. While charging, the current battery level will be
indicated by the corresponding flashing LED.
• Once the battery is fully charged, the battery level indicator LEDs will be lit steadily.
• Disconnect the connected cables.
