Resetting the display module

If the wattage readout is frozen, stuck on a pattern, or showing a number that doesn't change no matter what's connected, a reset usually clears it without affecting charging or your firmware version.

Applies to

All Liter cables, 1.0 m & 2.0 m

Time required

~1 minute

Step-by-step instructions

Disconnect both ends

Unplug the cable fully from both the power source and the device. The display should go dark within a moment.

Wait ten seconds

This lets the display module's chip fully power down rather than staying in a low-power standby state.

Reconnect the host end only

Plug the display end back into a wall adapter, without connecting the device end yet. You should see the display briefly flash once.

Reconnect the device end

Plug the other end into your phone or laptop. The display should now show a live wattage reading instead of the stuck pattern.

Reconnect the device end

Let it charge for a minute and check that the number updates normally rather than freezing again. If it does, see Notes below before contacting support.

Do not unplug during an update

If power is lost mid-update, the display will stay dark on reconnect. This is recoverable — see "Display won't light up after a firmware update" in Troubleshooting.
