Everything You Need

Built around one idea: stop overcharging.

Battery Health

Charging past 80% is the biggest driver of long-term battery wear. AutoStop keeps you under that line automatically.

Auto-Stop Charging

At your chosen percentage, the circuit physically disconnects — not a software timer, a real mechanical break.

Easy Setup

Plug it between your existing charger and cable. Pick a percentage. That's the entire setup process.

Universal Compatibility

Works with any USB-C PD or QC charger and cable, up to 140W — phones, laptops, tablets, handhelds.

Safety First

A physical contact break means no trickle current and no heat buildup once your limit is reached.

Everyday Convenience

Set it once. No app to open, no notifications, nothing to remember every night.

Why It Matters

Lithium batteries fail at 100%, not at 0%.

  • A battery held at full charge sits at its highest internal voltage — the biggest driver of long-term capacity loss.
  • Apple and Tesla both cap daily charging around 80–90% in their own longevity modes.
  • Charging past capacity generates heat with nowhere to go. Stopping the circuit stops the heat too.
Compatibility

Works with the USB-C you already own.

Questions

Before you ask.

Will this slow down my charging speed?

No. It passes through the full power your charger already supports, up to 140W.

Do I need an app or Bluetooth?

No. Everything is controlled by the single button on the device.

What happens if I unplug early?

Nothing changes — it only acts once your chosen percentage is reached.

What's in the box?

One AutoStop adapter. Your existing charger and cable are still required.
