Charging your phone with a higher watt charger won't harm your device, but it won't necessarily charge it faster. Here's why:
- Wattage (W) is a measure of power, which is the rate at which energy is transferred.
- Voltage (V) and Amperage (A) are the components of wattage: W = V x A.
- Your phone's battery has a specific charging rate, determined by its internal circuitry.
- A higher wattage charger provides more power, but your phone's battery will only draw the amount of power it needs to charge at its designated rate.
For example:
- If your phone's battery can charge at 18W, and you use a 30W charger, the phone will only draw 18W of power, charging at its maximum speed.
- However, if you use a 10W charger, the phone will charge at a slower rate because the charger cannot provide enough power to meet its full charging capacity.
Therefore, using a higher wattage charger than your phone's maximum charging rate won't damage your device but won't result in faster charging. You'll only see faster charging if the charger provides enough power to meet or exceed your phone's maximum charging rate.
