Frequently asked questions

Before attempting any troubleshooting, please ensure both the Leo App and your Leo device are updated to the latest version.

Steps to Update:

1. Update the Leo App: Download the latest version at www.liionpower.nl/app

2. Connect Leo to a charger (ensure it’s powered on).

3. Open the Leo App and connect to Leo via Bluetooth.

4. Update Leo through the app.

Important Notes:

• Do not charge any devices with Leo during the update process.
• Keep your smartphone close to Leo while the update is ongoing.
• After the update, allow Leo to install and restart itself automatically.
• Do not unplug Leo while this process is ongoing.

Once the update is complete, fully unplug Leo and plug it back in. Your Leo should now be updated and fully operational.

Most issues (99%) can be resolved by following the three steps outlined in our manual, available at https://www.liionpower.nl/manual

Steps to Resolve Issues:

Fully unplug Leo

Step 1: Connect Leo to a charger.

Step 2: Set the charging mode using the button.

Step 3: Connect the charging device.

If Leo does not start charging within 30 seconds, fully unplug Leo and repeat steps 1, 2, and 3.

We recommend trying these steps first before proceeding with other troubleshooting methods.

Most of the time, a red LED can be resolved by fully unplugging Leo and reconnecting it, following the 3 steps outlined in the manual.

If the red LED persists, it indicates that Leo requires an immediate firmware update and will not operate until the update is completed.

Steps to Resolve:

• Connect Leo to a charger (the RED light should remain visible).
• Open the App and connect to Leo via Bluetooth.
• Update Leo through the app—even if the app indicates that Leo is already up-to-date, proceed with the update.

Once the update is completed and fully installed, fully unplug Leo and plug it back in. Leo should now be updated and operational again.

If the red light persists, the update was not successful. Please try the steps again. So far, all RED light issues have been resolved through this process.

In Smart Mode (white LEDs), Leo is designed to stop charging before your device reaches full capacity. If your phone/tablet indicates that it charged to 100%, a combination of these two common reasons may explain why:

• Charger specifications:
  For Smart Mode to work effectively, Leo requires a charger that delivers at least 5V/2A. Some chargers, especially older ones, provide only 1A or even 0.8A, which can interfere with Leo’s ability to analyze the charging process accurately. Ensure your charger meets these specifications and that your cable is not defective.

• Phone state-of-charge indication:
  Some phones/tablets display 100% charge even when the actual charge is closer to 90%. Manufacturers often do this to give the impression of faster charging times. You can check the charge graph in the Leo app to see the actual point where Leo stops charging. After Leo stops charging, if you switch to Ghost Mode or Safe Mode, you may notice the phone continues charging for some time, indicating it wasn’t truly at 100%. We’ve provided an example screenshot of this process here. You can verify this yourself, by looking at the charge graph in the Leo app while charging your devices!

Looking ahead:
We’re working on an app update that will allow you to set a custom charge limit at any prefered percentage, for devices that can run the app, like smartphones and tablets. This feature is expected to launch in January.

We have added a feature called 'Higher Charge Limit'. This feature adjusts Leo's autonomous charge limit in Smart Mode to a higher percentage in specific cases where the default limit feels to low.

You can enable this in: 'Settings > Advanced Settings > Higher Charge Limit'

• For some users or devices, the default limit may feel insufficient for daily needs. enabling this feature allows devices to charge futher before stopping.
• For older or long-unused devices with slightly degraded batteries, this feature can help prevent premature charging stops.

Yes. Leo can be used to charge a wide range of different devices, such as smartphones, headphones, speakers or even your PlayStation 5 controllers. Practically everything that is charged through a USB port, up to 100W.

Absolutely! In the default 'Smart Mode', the LED bar will automatically turn off after a few minutes of charging, ensuring it doesn't create any light disturbance during nighttime. We're continuously working on enhancing the app and plan to provide users with customization options to control how frequently and for how long the LED bar remains active.

No! Leo can be used simply as a Plug & Play. It will execute all the standard functions autonomously. The app is only for those who like to customize their settings, and want more insights into battery analytics and health. If you want the app, it is available for both Android and iOS at www.liionpower.nl/app

Although one Leo can be used to charge any number of devices, it can only charge ONE device at a time! Therefore, in our team, everyone uses several Leo’s per person.
