4. Operation
4.1. Charging the power pack
Warning – rechargeable battery
• Do not charge the power pack via your PC or notebook. The charging currents can damage the
USB port on the PC or notebook.
• Only use suitable charging devices or USB connections 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.
• Avoid storing, charging and using in extreme temperatures and at extremely low atmospheric
pressures (such as at high altitudes).
• Charge regularly (at least quarterly) during periods of prolonged storage.
• Start the power pack charging process by connecting the enclosed USB-A to USB-C cable to the
USB-C input on the power pack (IN 5V/2A) and to a suitable USB charger. To do this, consult the
operating instructions for the USB charger you are using. Alternatively, the power pack can also be
charged via the micro-USB port (IN 5V/2A).
• 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.
• Each status LED corresponds to 25% of the capacity. The permanent illumination of an LED
indicates that the capacity has already been reached. If three LEDs light up and the fourth one
ashes, the power pack is at least 75% charged.
• If all four status LEDs light up, the full capacity is available.
• Press the button on the power pack to switch this on and to determine the power pack's current
capacity.
• Press the button twice until the status LEDs go out to switch the power pack off.
4.2. Charging devices
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 does not exceed 3000 mA.
• 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!
• Please do not charge simultaneously at the two USB and USB-C outputs since this signi cantly
reduces the charging current. The charging period increases signi cantly as a result and the
power pack may, in certain circumstances, become overloaded.
