- Rukovanje: Izbjegavajte ispuštanje ili izlaganje punjača jakim udarcima. Ne pokušavajte rastavljati ili modificirati punjač.
- Održavanje kablova: Pazite da kablovi za punjenje nisu oštro savijeni ili zapetljani, jer to može oštetiti kablove i utjecati na performanse punjenja.
10. Otkrivanje problema
If you encounter any issues with your MateStar charger block, please refer to the following common troubleshooting steps:
- Uređaj se ne puni:
- Provjerite je li punjač sigurno uključen u ispravnu zidnu utičnicu.
- Provjerite je li kabel za punjenje pravilno spojen i na punjač i na vaš uređaj.
- Pokušajte koristiti drugi kabel za punjenje kako biste isključili mogućnost neispravnog kabela.
- Testirajte punjač s drugim uređajem kako biste potvrdili njegovu funkcionalnost.
- Sporo punjenje:
- Verify that your device and cable support fast charging (PD or QC) and are connected to the appropriate port (USB-C for PD, USB-A for QC).
- Provjerite da nijedna pozadinska aplikacija na vašem uređaju ne troši previše energije.
- Charging multiple devices simultaneously may distribute the total 40W output, potentially reducing individual port speeds.
- Pregrijavanje punjača:
- Disconnect the charger and allow it to cool down.
- Pazite da se punjač nalazi u dobro prozračenom prostoru i da nije pokriven.
- Ako se pregrijavanje nastavi, prekinite upotrebu i kontaktirajte korisničku podršku.
