Auto-Disconnect Overcharge Protector — USB-C
Stops charging the second your battery hits 100%.
Leave a phone on charge overnight and it doesn't just sit at 100% — it trickle-cycles between 99% and 100% for hours, and that slow cycling is one of the biggest causes of early battery wear. This little adapter sits between your existing cable and your phone, watches the charge, and physically disconnects the moment it's full. No trickle, no overnight cycling, no babysitting the charger.
Why you'll love it
- A physical disconnect, not just software — a spring-loaded connector ejects itself when the battery reads full, cutting current completely rather than just slowing it down.
- Protects battery health — stops the 99%-to-100% trickle cycle that wears batteries out well before their time.
- Works with what you already own — it's a pass-through adapter for your existing USB-C charger and cable, not a replacement for either.
- LED status light — lets you see charging status at a glance.
- Manual eject too — push the side buttons any time to release it before it disconnects on its own.
Made for
Overnight charging · nightstands · desks and offices · shared or family chargers · kids' devices · anywhere you'd otherwise leave a phone plugged in for hours
How it works
- Plug the adapter into your existing USB-C charging cable.
- Plug the other end into your phone, tablet or other USB-C device.
- Charge as normal — it senses when the battery is full and disconnects automatically.
- Push the side buttons any time to release it manually.
In the box
- Auto-disconnect adapter (USB-C)
- Quick-start guide
Note: this is a pass-through adapter — it's designed to work with the USB-C charger and cable you already have.
