If you’ve ever left your phone charging overnight and woken up to a warm device, you’ve experienced overcharging — and your battery has silently paid the price.
Most people don’t think twice about it. You plug in before bed, unplug in the morning. But lithium-ion batteries, which power every modern smartphone, tablet, and laptop, are actually damaged by staying at 100% charge for extended periods. Over months and years, this degrades your battery’s capacity — and there’s no fixing it without replacing the battery entirely.
That’s the problem MillionHz set out to solve.
What Is Auto Cut-Off Technology?
An auto cut-off charging cable is a smart cable that automatically stops delivering power to your device once it reaches 100% battery. Unlike a regular cable, which keeps pushing current into your battery indefinitely (relying on your phone’s internal circuits to manage it), a cut-off cable removes power entirely at the source.
The MillionHz Smart Auto Cut-Off Cable does exactly this. Once your device is fully charged, the cable cuts off power flow on its own — no app, no settings, no manual unplugging required.
You’ll also notice a built-in LED indicator that shows charging status at a glance. When the light changes, your device is done charging. Simple, visible, and smart.
Why Does Overcharging Damage Batteries?
Lithium-ion batteries are most stable between 20% and 80% charge. Holding them at 100% — especially while connected to power — causes a process called lithium plating, where lithium ions become trapped in the battery’s anode. Over time, this reduces the battery’s ability to hold a charge.
This is why a two-year-old phone often dies by lunchtime even though it charged fully overnight. The battery hasn’t failed — it’s been slowly worn down by thousands of hours at maximum charge.
An auto cut-off cable addresses this at the source.
