Your battery has been quietly dying every night. PowerGuard was built to stop it.

Most people don't realize it — but leaving your phone plugged in after it hits 100% is one of the fastest ways to age your battery. Heat builds. Voltage stress accumulates. Month after month, your battery capacity shrinks. The PowerGuard 140W GaN Charger was engineered specifically to fix this.

The charger that actually knows when to stop.

PowerGuard features a built-in Smart Cut-Off system. The moment your device reaches 100%, it doesn't trickle charge, it doesn't hover at full — it completely cuts power. No heat. No stress. No silent damage while you sleep. Just a fully charged device and a battery that stays healthy for years, not months.

140W of serious, intelligent power.

This isn't just a protection device — it's a powerhouse. PowerGuard delivers up to 140W of GaN-powered output, fast-charging your MacBook Pro, iPad, iPhone, Android devices, Nintendo Switch, and virtually anything USB-C. GaN (gallium nitride) technology runs dramatically cooler and more efficiently than traditional silicon chargers, packed into a compact form that slips into your pocket, bag, or travel kit without the bulk.

SmartSense chip — right power, every time.

The built-in SmartSense chip reads your device the moment you plug in and delivers the precise wattage it needs. No guessing. No risk of overloading a smaller device. No wasted energy. It adapts automatically — you never have to think about it.

Protection built into every layer.

• Smart Auto Cut-Off at 100% — charging stops completely, no overcharge damage
• Overcurrent protection — shields your device from power surges
• Overvoltage protection — keeps voltage within safe limits
• Temperature monitoring — detects heat and responds before it becomes a problem

A note from our team: The Smart Cut-Off activates when your device reaches 100%. If you unplug and reconnect, it'll charge again to full — that's by design. Our recommendation: plug in before bed, let PowerGuard handle the rest. Wake up to a full battery and a healthier one.
