Iridium Accessories for the 9555, 9575 Extreme, 9505A and GO
Spare batteries, chargers, external antennas, docks and cases, all matched to the Iridium handset you own. Check the model on the back of your phone first; the parts are not interchangeable.
What Iridium handset owners need first
Four Iridium devices account for nearly every accessory question we get: the 9555, the 9575 Extreme and Extreme PTT, the older 9505A, and the Iridium GO hotspot. Each has its own battery, its own charger connector and its own antenna adapter. The order to buy in is the same for all of them: a spare battery, a way to charge away from the wall, an external antenna for the vehicle or boat, and a case.
The 9555 is rated for 4 hours of talk and 30 hours of standby on its standard battery, and its kit ships with a magnetic antenna and the TNC antenna adapter. The 9575 Extreme adds IP65 and MIL-STD 810F ratings and an SOS button, and its BAT31001 battery reaches 90 percent in about 3 hours when charged in the handset at room temperature. The Iridium GO gives 5.5 hours of talk and 15.5 hours of standby and is IP65 rated, but it is a voice, text and app device, not satellite internet.
Batteries and chargers
Cold weather and long signal searches drain a satellite battery faster than the rated figures suggest. Carry a spare for your exact model and a charger that works where you are going.
External antennas, adapters and cables
Any Iridium handset used inside a vehicle, wheelhouse or building needs an antenna outside with a clear view of the whole sky. Buy the adapter for your model, then the antenna, then the cable length you need.
Docking stations for the 9555, 9575 Extreme and 9505A
A dock turns the handset into a fixed phone with charging, an external antenna port and, on the higher tiers, a telephone line and a privacy handset. Take the phone out and it is portable again.
Iridium GO accessories and the wall mount
There is no dock for the GO. The wall mount bracket kit, part WBKT1301, fixes it to a bulkhead or cabin wall with a quarter inch screw, the antenna adapter connects an external antenna, and the 5 metre outdoor USB cable is what Iridium recommends for continuous power. The GO handles calls, texts and specific apps; it is not satellite internet.
Holsters, cases and protection
Iridium handsets are IP65 rated: dust tight and jet resistant, not submersible. A holster for daily carry and a hard case for the full kit keep one working for years.
Charging on the move: vehicle, USB, solar and multi bay
The Iridium DC auto charger runs a 9555 or 9575 from a 12 V socket. The AC travel charger and the international plug kit handle wall outlets abroad. For the GO, the GO AC charger with international adapters and the GO vehicle charger adapter do the same job.
Off grid, the Deluxe Iridium Solar Kit combines a 30,000 mAh solar battery pack with a 5 V 2.1 A USB output, a USB cable and a T5000 watertight hard case with pluck foam. It charges the 9505A, 9555, 9575 and PTT handsets. For a laptop or a terminal, use a power station from Off-Grid Power instead.
Teams that rotate handsets should look at the 9555 single bay and four bay chargers. The four bay unit conditions and rapid charges standard and high capacity 9555 batteries, switches to maintenance mode when full, and runs from AC or 12 V DC.

How to choose an Iridium external antenna
Three questions settle it: which handset, how far the cable runs, and whether the antenna stays put.
Match the adapter to the handset
The 9555 uses a TNC female antenna adapter, part H2AA0802, included in the phone kit and sold separately if lost. The 9505 and 9505A use a different adapter. The Iridium GO uses a 15 cm TS9 to TNC female adapter cable. The 9575 Extreme has its own antenna and USB power adapter. Get this piece right and every Iridium antenna with a TNC connector will fit.
Pick magnetic or fixed
A magnetic mount is for vehicles you do not want to drill. The 5 metre Iridium magnetic antenna needs a flat steel surface to grip, weighs 405 g, and is rated from minus 40 to plus 70 degrees Celsius. Fixed screw mount, low profile and mast antennas are for permanent installs on boats, buildings and fleet vehicles.
Check the cable length
Passive antennas are limited to roughly 30 metres of coax; the 30 metre Iridium cable kit is the longest passive run we sell. Beyond that, the Iridium active antenna has an amplifier in its base and supports preset cable lengths from 27 to 160 metres. Do not shorten a supplied active antenna cable; cutting it voids the warranty. The GO exec has its own 5 metre limit, extended with the GO exec LITE antenna kit and a datahub over Ethernet.
Add GPS if the device needs it
The 9575 Extreme uses GPS for its SOS and tracking features. The Iridium and GPS magnetic antenna and the low profile Iridium and GPS antenna carry both signals so those features work from inside a vehicle. A plain Iridium antenna will make calls but will not feed the phone a GPS fix.
Iridium dock comparison
Which dock depends on whether you want a charger with an antenna port, a vehicle hands free setup, or a phone line into a building or a vessel.

Essential Guide to Choosing Iridium Satellite Phone Accessories
To get the most out of the Iridium network’s 100% global coverage, it is important to equip your device for your specific environment. Here is a breakdown of the most popular accessories designed for individual users and outdoor enthusiasts:
Portable Power & Charging Solutions
Nothing is more critical than a charged battery when you're off the grid. We offer high-capacity Iridium batteries and international charging kits that work with any wall outlet worldwide. If you are traveling by vehicle, our 12V DC adapters allow you to charge while you drive. For long-distance hikers and campers, we highly recommend our solar-ready charging cables, which ensure you can replenish your battery even when you are miles from civilization.
Boosting Signal with External Antennas
If you plan to use your satellite phone from inside a vehicle, cabin, or tent, you may experience signal interference. An external Iridium antenna solves this by allowing you to place a small magnetic or fixed mount on the exterior of your structure. This provides a clear line of sight to the satellites, ensuring fewer dropped calls and more consistent data speeds for Iridium GO! users who need to check weather reports or send text messages.
Rugged Protection and Carrying Options
Your Iridium phone is an investment in your safety. Protect it with our range of heavy-duty cases and holsters. We stock everything from simple belt clips for easy access during a hike to waterproof, impact-resistant cases for maritime use or extreme expeditions. Keeping your device protected from dust, moisture, and accidental drops ensures it will be ready to perform the moment you need it.
