Auto Disconnect USB-C Charger Adapter for Battery Protection

Your charger doesn't know when to stop.

Most chargers keep pushing power long after your battery hits 100%. That slow, invisible stress — heat buildup, trickle overcharging, overnight cycles — quietly shortens your battery's lifespan over months and years. A small change in how you charge can make a meaningful difference.

Whether you charge overnight on your nightstand, at your desk during the day, or while traveling, this auto-disconnect adapter fits seamlessly into your existing setup. Plug it between your charger and your device — it handles the rest, cutting power automatically once a full charge is reached.

The KH-51 USB-C charging adapter is designed to help protect your device's battery by stopping the charge at the right moment. No apps, no settings, no manual unplugging — just smarter charging, every time.
