Stop guessing your keyboard's charge — see it in your Windows taskbar.
No keyboard battery in the Windows taskbar the way a laptop shows it — so TrayJuice puts that reading where you already look. Confirmed on Lemokey P1 Pro over Bluetooth; Keychron and more models in progress.
- Live tray icon for your primary device
- Multi-device window with battery panels
- Local only — no cloud, no account
Also in the system tray
Why TrayJuice?
Before you're stranded
See your charge level before a long session, meeting, or match — not when the lights start flashing.
One glance away
No extra apps to open, no digging through Bluetooth settings. Your battery lives where you already look.
Lightweight by design
TrayJuice starts once and fades into the background. Open the window only when you want more detail.
What you get
- Live taskbar icon
- A battery icon in your system tray that updates on a schedule you pick — from every few seconds up to every five minutes.
- Low-battery alerts
- Optional Windows notifications when your charge drops — plus connect and disconnect alerts if you want them.
- Automatic setup
- Pair your keyboard in Windows, launch TrayJuice, and it handles the rest — no long configuration flow for supported devices.
- Detail when you want it
- A compact window with connection status, device name, battery percentage, and last update — hidden until you open it.
- Your preferences
- Choose refresh interval, auto-start with Windows, notification behaviour, and whether the app minimizes back to the tray.
- When something's off
- Built-in troubleshooting for those moments when pairing or readings don't behave — without leaving the app.
- Multiple devices
- Monitor up to 3 devices at once; the lowest battery (or your chosen primary) shows in the taskbar.
- Primary device picker
- Choose which device is displayed as primary in the taskbar, or keep the default lowest-battery device.
- Keychron mouse support
- TrayJuice can monitor Keychron mice and show battery level in the taskbar.
