Checking the battery:
Make sure the booster battery is fully charged. If the battery is empty, please charge it with the included USB-C cable.
2. Checking the charging accessories:
Check if there is a problem with the charging cable or power adapter. Try charging the device with a different USB-C cable and power adapter.
Note: Do not use a fast charging power adapter or a fast charging USB-C cable as they may not be compatible.
3. Limescale deposits:
Check the booster for limescale deposits. Limescale can affect H2 bubble formation during electrolysis and reduce efficiency.
If limescale deposits are present, use citric acid to descale the booster. For descaling instructions, see our descaling FAQ.
