140W Physical-Disconnect Battery Guard, auto&self eject charger,Smart Auto-Stop Charging Accessory for Mobile Smartphones & Handheld Devices
Modern smartphones, tablets, gaming handhelds, and laptops all share a silent killer: overcharging. Leaving devices plugged in overnight or for extended periods degrades lithium battery health, reduces capacity, increases heat buildup, and creates unnecessary safety risks. Traditional chargers and smart plugs only cut power at the wall—but the cable and connector remain live, and trickle current continues to stress your battery. Even "intelligent" chargers use electronic switches that can fail, leak current, or still allow micro-charging cycles. If you want true, complete, physical disconnection from power the moment your device reaches full charge, this 140W Physical-Disconnect Battery Guard with Auto/Self Eject Charger provides the ultimate battery protection solution.
This revolutionary charging accessory combines a high-power 140W PD charger with a patented electro-mechanical ejection system that physically disconnects the charging cable from your device when charging is complete. Unlike software-based or relay-cut chargers, this device creates a genuine air gap—zero voltage, zero current, zero trickle charge. It supports auto mode (automatic ejection at full battery) and self-eject mode (manual one-touch release). With advanced battery voltage monitoring, temperature protection, and universal compatibility, it safeguards your valuable devices from the #1 cause of battery degradation.
🌟 Key Features
⚡ True Physical Disconnection & Absolute Isolation
Built-in electro-mechanical actuator creates a genuine physical air gap between charger and device. When charging completes, the connector physically ejects or disengages—zero electrical contact, zero parasitic drain, zero trickle current. This is true battery protection, not simulated.
🔋 Smart Auto-Eject at Full Charge
Intelligent battery voltage monitoring chip detects when your device reaches the optimal charge level (configurable: 80%, 90%, 95%, or 100%). Automatically triggers physical disconnection within 10 seconds of hitting target level. Never wake up to an overnight-overcharged battery again.
👆 Self-Eject Mode for Manual Control
One-touch capacitive button enables instant physical disconnection on demand. Perfect for when you need to unplug without reaching behind your desk or bed. The satisfying mechanical ejection action confirms complete power isolation.

⚡ 140W Ultra-Fast Charging Support
Supports the latest PD 3.1 fast charging protocol up to 140W. Charges MacBook Pro, iPhone, Samsung, Steam Deck, ROG Ally, Switch, tablets, and ultrabooks at maximum speed before intelligent disengagement. High-power gallium nitride (GaN) technology ensures efficient, cool operation.
🛡️ Multi-Layer Safety Protection
Over-voltage protection, over-current protection, short-circuit protection, and thermal monitoring. The physical disconnect adds a fifth layer of safety unavailable in any standard charger. When ejected, there is no arc, no spark, no residual energy—completely failsafe.
🔌 Universal Device Compatibility & Smart Recognition
Automatically identifies connected device type and negotiates optimal charging protocol (PD, QC, PPS, AFC, SCP, Apple 2.4A). Works with any USB-C smartphone, tablet, handheld gaming device, or laptop. The ejection mechanism is gentle and safe for all ports.
