Ensure the device is connected using the original Iridium power adaptor. This outputs 5V DC at 3 amps. You can also use the cigarette lighter adaptor. If this is not available, please connect it to another USB socket offering at least 2 amps.

Please check the condition of the USB-C cable, any oxidation on the ends or damage to the cable it will not work, please try another cable.

Are you 100% sure the USB or cigarette outlet is getting power? Do other devices charge okay using those outlets? Does a multimeter show power to the outlets?

Disconnect the pig-tail connector to disconnect the External Antenna. The GO exec is unable to charge successfully while connected to the External Antenna because it draws too much power.

Try charging the GO! exec for an extended period of time? If the battery has been run flat, charge the unit overnight and then test again.

If the device is turned off, plugged in and charging, the LED should be blue.

Check the battery temperature (physically feel the bottom of the unit); if it is warm, let it cool before charging.

If the unit is stuck in a reboot cycle, remove it from the charger for a few hours and then try to charge it fully.

The supplied AC charger can operate in ambient temperatures up to 25°C. At higher temperatures and during heavy loads, it will reduce or stop charging.

Factory reset the unit by pushing a paperclip into the hold above the SIM card slot and holding it down for 15 seconds until you see two cogs on the LCD screen while connected to power.

IMPORTANT: For protection and long life, the Iridium GO exec will only allow charging when the battery temperature is between 0°C (32°F) and 45°C (113°F).
