Charging Recommendations for Geode GNS3

29 Jan 2025

This article provides charging requirements, recommends the best way to charge the Geode, and explains what to do if a Geode does not charge.

The cable and wall charger that the Geode is supplied with has the right specifications to charge the Geode fully. A USB port on a computer does not provide an adequate amount of power to charge the device.

Wall chargers:

  • 15 W
  • 100–240 V AC
  • Adapters for the US, UK, and EU
    • AU/NZ adapters are supplied separately. 
  

Cables:

  • USB-C to USB-C
    • Recommended for use as a primary charging cable. Use this when the device is powered on and charging at the same time. This cable can also be used for data transfer.
  • USB-A to USB-C
    • A legacy cable used for charging when the receiver is powered off. This cable can also be used for data transfer.
  

RS-232 Pin-9 Power input line

  • 15 W minimum (such as 12V @ 1.25A or 5V @ 3A)
  • Tolerance of 5 to 17 VDC
  

When not in daily use, charge the Geode periodically to 50% power. Do not allow the battery to become completely depleted as it may not recover. If you do not plan to use the Geode for more than a month, charge/discharge the battery to about 50% (the optimal charge level for storage).
