The Automobile (DC) Charger enables rapid charging of your Iridium Extreme® handset from standard DC sources such as vehicles, boats, or solar-powered systems. The charger plugs directly into the DC accessory socket (12 V), then connects to the handset via the compatible adapter. This ensures your device remains operational while on the move.
Important: This charger must be used only with the adapter approved for vehicle/auto charging. Using alternative connections may prevent proper charging or may not allow full operation.
Compatibility & Technical Specifications
- Compatible with Iridium Extreme (9575), also backward-compatible with Iridium 9555 and Iridium 9505A.
- Typical input: from 10 – 32 V DC (vehicle battery or accessory socket)
- Typical output (to handset): roughly 6 V DC at ~800 mA (varies by model)
- Fast-charge time: approximately 3 hours to reach 90% capacity under standard conditions (≈25 °C) when used with a compatible battery.
- Certified for use at altitudes up to 2,000 meters above sea level.
- Operating temperature guidelines: 0 °C to ~40 °C (32 °F to 104 °F) recommended for best performance.
How To Use the DC Charger
- Connect the charger’s plug into the vehicle’s DC accessory socket (commonly the “cigarette-lighter” type).
- Verify the socket provides proper voltage (10-32 V DC) and is fused accordingly.
- Attach the charger’s output cable to the charging adapter mounted on the bottom of the handset (make sure the correct adapter is in place).
- Check that the handset displays the charging indicator (battery icon or charging animation).
- While charging, you may continue using the handset for calls/text, but ensure you keep the handset’s antenna extended and unobstructed for the best satellite signal.
- When charging is complete, unplug the charger and secure the handset and cable neatly to avoid damage in mobile conditions.
Best Practices & Usage Tips
- When using in a vehicle, mount the handset or cradle in a location with a good roof-mounted or clear sky view for optimal satellite connectivity.
- Avoid leaving the charger plugged in when the handset battery is full, as overcharging may shorten battery life over time.
- If using solar or non-standard DC sources (e.g., 24 V panels, marine systems), verify voltage regulation and wiring meet the charger’s input specification (10-32 V).
- Keep the charger cable and vehicle socket clean and free of debris; make sure the connection is secure.
- In cold climates (< 0 °C) or very hot environments (> 40 °C), charging efficiency may drop. Plan accordingly and avoid charging in extreme temperatures if possible.
Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Handset not charging or no indicator | Faulty vehicle socket or insufficient voltage | Check fuse, verify socket voltage; try alternate socket or power source |
| Charging indicator flickers or stops | Poor connection or high ambient temperature | Reconnect firmly; move the handset to a moderate temperature |
| Handset loses signal during use | Antenna blocked or inside vehicle paneling | Extend antenna, reposition handset for unobstructed view of sky |
| Charger becomes warm or hot | High current draw or prolonged use | Disconnect when full; use a ventilated location; limit extended use |
