4. Operation
4.1. Charging the power pack
• Start the power pack charging process by connecting the enclosed Micro-USB charging cable to
the Micro-USB input on the power pack (IN 5V/2A) and to a suitable USB charger. Alternatively,
you can also charge the power pack via the USB-C input (IN 5V/2A). To do this, consult the
operating instructions for the USB charger you are using.
• The charging process begins and ends automatically.
• Fully charge the power pack once before using it for the rst time.
Note – capacity
• During the power pack charging process, the capacity is displayed constantly.
• The LED capacity indicator shows the current charge level in percent. The capacity indicator
ashes during the charging process.
• When the capacity indicator shows a constant 100%, the power pack is fully charged.
• Press the button on the power pack to switch this on and to determine the power pack's current
capacity.
• To switch the power pack off, press and hold the button until the LED indicator goes out.
Warning – rechargeable battery
• Only use suitable charging devices or USB ports to charge the product.
• Do not use defective chargers or USB ports and do not attempt to repair them.
• Do not overcharge the product or allow the battery to completely discharge.
• Do not store, charge or use the device in extreme temperatures.
• Charge regularly (at least quarterly) during periods of prolonged storage.
4.2. Charging devices
• Connect the enclosed Micro-USB charging cable to the USB port on the power pack (see 7.
Technical Data) and to the Micro-USB port on your device (mobile phone, Smartphone, etc.).
• In certain circumstances, the enclosed charging / connecting cable may not match the USB port on
your device. In this case, use the USB cable that came with your device.
• The charging process begins automatically. During the charging process, the LED capacity indicator
indicates the power pack's remaining available capacity.
• The current battery charge status of your device is indicated on this.
• Terminate the charging process and switch the power pack off by pressing the button on the
power pack twice in quick succession. The LED indicator goes out.
• In the event that no device is connected, the power pack switches itself off automatically.
Warning – Connection of devices
• Before connecting a device, check whether it can be adequately supplied with the power pack's
current delivery.
• Ensure that the total current consumption of the connected device is not exceeded (see 7.
Technical Data).
• Note the instructions in your device's operating manual.
• You must obey the instructions and safety notes contained therein regarding the supply of
power to your devices.
• The power pack must not be charged and discharged at the same time!
Note – optimised charging
• Optimised charging means that the power pack recognises the connected device, supplies it with
the ideal current strength and therefore reduces the charging time to a minimum.
