Can I use a higher watt charger for my phone?

Yes, you can use any power charger for your mobile phone, but it will only work if the charger output is 5 volts. The charger output that does not 5 volts damages and burns the phone. As if you were using 9v or 12 volts. Yes, you can use any power charger for your mobile phone, but it will only work if the charger output is 5 volts.
