NILLKIN Cube Pocket Keyboard: How to Pair & Switch Up to 3 Devices

The NILLKIN Cube Pocket Keyboard lets you pair up to three Bluetooth devices and switch between them without starting from scratch each time. Whether you're using a phone, tablet, or laptop, all you need are a few simple keyboard shortcuts.

This guide covers first-time pairing, switching between devices, and troubleshooting common Bluetooth connection problems.

How to Pair the Cube Pocket Keyboard

The Cube Pocket Keyboard supports three Bluetooth channels: BT1, BT2, and BT3. Each channel can be assigned to a different device, but only one channel is active at a time.

1. Turn on the keyboard. Unfold the Cube Pocket Keyboard and switch it on.
2. Select a Bluetooth channel. Press Fn + Q for BT1, Fn + W for BT2, or Fn + E for BT3.
3. Enter pairing mode. Press Fn + C. The blue Bluetooth indicator will flash.
4. Connect your device. Open Bluetooth settings on your phone, tablet, or computer and select Cube Pocket Keyboard.

Once connected, open a notes app or text field and try typing to confirm the connection.

How to Connect a Second or Third Device

To connect another device, select a different Bluetooth channel and repeat the pairing steps.

For example, you could assign BT1 to your phone, BT2 to your tablet, and BT3 to your laptop. You can choose any arrangement that works for you.

How to Switch Between Paired Devices

Once your devices are paired, use these shortcuts to switch between them:

Shortcut	Function
Fn + Q	Switch to BT1
Fn + W	Switch to BT2
Fn + E	Switch to BT3
Fn + C	Enter Bluetooth pairing mode
Fn + R	Reset the keyboard (hold for 3 seconds)

Important: You don't need to press Fn + C every time you switch devices. Simply select the channel you've already paired, and the keyboard will attempt to reconnect automatically.

Three-device connectivity means you can switch between saved devices, not type on all three simultaneously.

Bluetooth Settings for Different Devices

After selecting a channel and pressing Fn + C, find Cube Pocket Keyboard in your device's Bluetooth settings.

Device	Bluetooth Settings
iPhone / iPad	Settings > Bluetooth
Android	Settings > Connected devices / Bluetooth
Windows 11	Settings > Bluetooth & devices > Add device
Windows 10	Settings > Devices > Bluetooth & other devices
Mac	System Settings > Bluetooth

Menu names may vary depending on your device and operating system version.

Troubleshooting Common Bluetooth Connection Problems

Keyboard Not Showing Up in Bluetooth Settings?

Make sure you've selected a Bluetooth channel and pressed Fn + C to enter pairing mode. Check that Bluetooth is enabled on your device, then search again.

Can't Switch Between Devices?

Confirm that the selected channel has already been paired and that Bluetooth is enabled on the target device. Use Fn + Q/W/E to switch channels rather than pressing Fn + C again.

Keyboard Disconnects After Being Idle?

The Cube Pocket Keyboard enters sleep mode after approximately 10 minutes of inactivity. Press any key for about 2 seconds to wake it and allow the Bluetooth connection to resume.

Still Not Connecting? Try a Reset

If the connection issue continues, follow these steps:

1. Press and hold Fn + R for 3 seconds.
2. The three Bluetooth indicators should flash rapidly three times.
3. If necessary, remove the previous keyboard connection from your device's Bluetooth settings.
4. Select a channel, press Fn + C, and pair the keyboard again.

If the issue continues after resetting, contact NILLKIN Support for assistance.

Frequently Asked Questions

Do I need to pair the keyboard every time I switch devices?

No. Once your devices are paired, use Fn + Q, Fn + W, or Fn + E to switch between them. You don't need to repeat the pairing process during normal switching.

Can I type on three devices at the same time?

No. The Cube Pocket Keyboard supports up to three paired devices, but only one Bluetooth channel is active for typing at a time.

What if my keyboard won't reconnect to a previously paired device?

Check that the device's Bluetooth is enabled and the keyboard has enough battery power. Try selecting the correct channel again. If reconnection still fails, follow the reset and pairing steps above.
