What are the recommended guidelines and specifications for chargers?

We recommend you use the included USB charging cable to charge your Jabra device.

If you use a third-party option, we recommend the following guidelines:

• Use a USB charger that is safety-certified for use in the country you are located in.
• Ensure the USB cable fits properly in the charging port.
• Do not charge the device if the charging ports or charger are wet or damaged.

Charging will occur, until the battery is fully charged, within the normal operating temperate range for charging of -5ºC to 50ºC (23°F to 122°F). Outside of this range, charging will cease so as to protect the battery and product, for example from overheating.
