The tiny smart adapter that physically cuts the power the moment your phone hits 100%. Stop overcharging your battery overnight — plug in, fall asleep, and let ChargeGuard pop itself off when the job is done. Works with iPhone, Android, earbuds and more.
Every night, your phone hits 100% in an hour — then sits plugged in for seven more, slowly cooking the battery. It's why your phone barely lasts a day after a year. ChargeGuard fixes it: a tiny smart adapter that physically pops off the moment your device is full. Plug in, fall asleep, and wake up to a healthy battery and total peace of mind.
An intelligent chip reads the current and voltage in real time. The instant your device reaches a true full charge, two contacts pop out and physically disconnect the charger — no overcharge, no wasted electricity, no babysitting.
Plug in before bed and stop worrying. ChargeGuard isolates the risks of leaving a device plugged in all night — overheating, battery stress, electrical faults — by simply cutting the power once you're full. Leave it charging and walk away.
Smaller than a watch face, yet supports up to 140W full-speed fast charging. Two modes — white light for phones and tablets, blue light for earbuds, shavers, power banks and toys. One little adapter for every device you own.
I'm always worried about leaving my phone plugged in all night and ruining the battery, so this is exactly what I needed. Two little pieces pop out and disconnect it from the charger once it's fully charged. Highly recommend.
She always worried about fire from charging overnight. Using this to charge our iPhones and iPads makes her feel much better because of the physical disconnect once it hits full. Simple to use and great peace of mind for $25.
When the device reaches full charge it physically cuts the connection instead of relying on the phone. Useful for phones, earbuds, tablets, power banks — anything you leave plugged in longer than necessary. Simple and genuinely useful.
I used it to charge my Android phone and earbuds. After they were fully charged it automatically disconnected within minutes. I love how small it is — easy to carry in a pocket or purse. I've been told it'll add life to my battery.
It's tiny — the size of my Apple Watch face but a little thicker. Fits my iPhone perfectly and looks either matte silver or champagne gold. Once your device shows 100% it disengages. A quality piece and so fun to watch. A must buy.
It automatically cuts power once the device reaches a full charge, which helps long-term battery health — especially for people who leave devices plugged in overnight. Supports fast charging and works with phones and earbuds. A unique gadget with a real purpose.
