Geode will not charge

15 Dec 2021

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.

Geode GNS3

Wall chargers:

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


  • 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

Geode GNS2 or GNS1

Wall chargers:

  • 2 Amp (or higher)
  • 5 Volts
Wall charger for the Geode.


  • 28 AWG / 1P + 24 AWG / 2C
  • 3 feet long
  • Large ferrite clamp near one end
Cable for charging the Geode.

An off-the-shelf cable may not charge the Geode completely because the electric current might not be sufficient. If your original cable is damaged or lost, you can order a replacement from our online store.

We recommend leaving the Geode GNS1 or GNS2 (or any of our products) plugged in over nights and weekends to ensure that you have a full battery at the beginning of each work day. If not using the Geode every day, it can be left plugged in for up to two weeks (potentially more). When storing the Geode for more than two weeks, a full battery can potentially be good for up to 6 months without being plugged in, though we still recommend plugging it in once a month to keep it topped off.

If the Geode will not charge, try leaving it plugged in overnight even if there are no signs of life. In some cases, the low-amperage current provided by attaching the Geode to a computer with the USB charging cable will trickle charge an over-discharged battery. If using the trickle charge method, leave it for several hours (overnight). If the trickle charge allows the battery to recover, you can then charge the Geode fully using the standard charger. If you cannot recover the battery, contact our repair center to replace the battery or charging port.
