140W USB-C Smart Charge Separator – Auto Overcharge Disconnect

140W Smart USB-C Charge Separator – Automatic Full-Charge Disconnect

Keep your devices safe and your battery healthy with this intelligent inline USB-C charge separator. Once your device reaches 100%, it physically disconnects the charging circuit — no trickle current, no heat buildup, no overcharge. Just plug it in between your existing cable and charger, and let it do the work.

Key Features

• Patented AI Auto-Disconnect Technology: Uses intelligent recognition to physically cut the charging circuit the moment your device is fully charged. Achieves true zero standby current, eliminating unnecessary energy draw and heat.
• 140W Full-Speed Passthrough: Dual-chip architecture supports up to 140W power delivery — fully compatible with PD3.1/3.0 and QC4+/3.0 protocols. Fast-charges laptops, smartphones, and more without bottlenecking your existing cables.
• Universal USB-C Compatibility: Works seamlessly with iPhone 15/16, Samsung flagships, MacBooks, Steam Decks, and any USB-C/Type-C device. Dual-current identification ensures a reliable physical disconnect every time.
• Dual LED Mode Intelligence: One-click toggle between modes:
  • White LED Mode — optimized for screen-based devices (phones, laptops)
  • Blue LED Mode — dedicated to non-screen electronics (power banks, electric razors, small fans, etc.)
• 360° Multi-Layer Safety System: Dual-channel isolation design with independent split structure ensures a reliable mechanical power-off every cycle. Built-in multi-layer firewall guards against over-voltage, over-current, and short-circuits — all housed in a high-temperature, flame-retardant shell.

Frequently Asked Questions

Q: How does the 140W USB-C charge separator prevent overcharging?

A: The separator uses AI-powered intelligent recognition to monitor your device's charge status. Once it detects a full charge, it physically disconnects the charging circuit — creating a true mechanical air gap with zero standby current. This is a hardware-level solution, not just a software limit, making it highly reliable for overnight and extended charging sessions.

Q: Is this USB-C charge separator compatible with all Type-C devices?

A: Yes. It is designed for universal USB-C/Type-C compatibility, including iPhone 15/16, Samsung Galaxy flagships, MacBooks, Windows laptops, Steam Decks, power banks, and other USB-C accessories. It supports PD3.1/3.0 and QC4+/3.0 protocols, so it works with virtually any modern fast-charging setup.

Q: Do I need a special cable or charger to use this separator?

A: No special equipment is needed. Simply plug your existing USB-C cable into the separator, then connect the separator to your charger as a bridge. This product is an inline accessory — your current cable and charger are required and are not included.

Q: What is the difference between the White LED and Blue LED modes?

A: White LED Mode is optimized for screen-based devices such as smartphones and laptops, which have their own charge-level indicators. Blue LED Mode is designed for non-screen electronics like power banks, electric razors, or small fans, which lack built-in charge displays. Toggle between modes with a single click to match your device type.
