Bold claim: Starlink’s premium gear may falter in real-world conditions, even in rugged environments. And this is the part most people miss: a high-end power setup that’s supposed to withstand harsh weather isn’t immune to quality control hiccups. Here’s what happened, why it matters, and what it means for users.
SpaceX’s Starlink introduced the Performance kit (Gen 3) priced at roughly $1,999, paired with an Advanced Power Supply (APS). After launching this lineup in June, the company discovered a water-sealing problem with the included power cables. To address the issue, SpaceX began offering free replacements for both AC and DC cables attached to affected units.
According to a Starlink support page published in December 2025, SpaceX confirmed that the cables failed to meet its quality standards. The Gen 3 Performance dish, which ships with the Advanced Power Supply, is designed for extreme conditions—think severe weather and use aboard boats. Yet the company notes that, under certain circumstances, the cables could be more susceptible to water ingress.
The support note explains that the problem emerged when the cables were used in wet environments. To maintain reliability, SpaceX asked customers with affected Advanced Power Supply Units to replace their AC or DC cables with the ones provided in the update package for their account.
Why did this issue pop up now? The situation might also explain why the Advanced Power Supply has briefly disappeared from Starlink’s online store, where it had been offered for about $200. SpaceX did not respond to immediate requests for comment, but the replacement program offers a practical workaround while reliability is reassessed.
What does this mean for users?
- If you own the Performance Gen 3 kit or an Advanced Power Supply, monitor your account for the free replacement cable package.
- If your setup operates in damp or jetting-water environments, prioritize installing the new cables to improve resistance to water exposure.
- Expect updates from Starlink as testing and quality checks continue to ensure the gear meets the claimed rugged performance standards.
