Why Your Battery Needs This

Lithium-ion batteries degrade faster when left at 100% charge for extended periods. Research from the U.S. Department of Energy highlights the importance of proper battery care to extend device lifespan. This auto-ejecting cable takes the guesswork out of battery health — simply plug in and sleep soundly.

Frequently Asked Questions

Q: How does the auto-eject feature work on this USB-C charging cable?

A: Once the connected device reaches a full charge, the built-in dual-chip detection system triggers a dual lever mechanism that physically ejects the USB-C connector from the device's port. This creates a true physical disconnection — not just a software cutoff — ensuring your battery stops receiving power immediately when fully charged, preventing overcharging and long-term battery degradation.

Q: Is this 140W auto-eject charging cable compatible with all USB-C devices?

A: Yes! This cable is universally compatible with all Type-C devices, including Android smartphones, tablets, laptops, power banks, shavers, and more. It supports Huawei Quick Charge protocols and up to 140W fast charging. Use the White LED mode for phones/tablets/laptops and the Blue LED mode for power banks and other electronics to ensure optimal detection.

Q: Will the auto-ejection mechanism damage my phone's charging port?

A: No. The cable features a built-in memory silicone pad that cushions the connector during ejection, and the dual lever ejection system is engineered to release gently and safely. This protects both the cable connector and your device's charging port from wear and impact during the automatic disconnection process.

Q: Is it safe to charge overnight with this cable?

A: Absolutely. This cable was specifically designed for overnight charging safety. The fireproof PC shell provides flame resistance, the zinc alloy body dissipates heat efficiently, and the auto-eject mechanism ensures your device is physically disconnected once fully charged — giving you complete peace of mind while you sleep.
