A charger for a phone may appear straightforward, yet what it supplies to your device is often significant. The reason is wattage, which informs us of the quantity of electricity that a charger is capable of supplying. Many are unaware of this measurement, yet knowing what number of watts a charger is capable of is important so you don’t end up with slow charging, overheating, or damage to your battery.
In today’s blog, let’s demystify charger wattage, what the common ones are, and what you need to consider while picking a charger for your smartphone.
What is Wattage Actually?
Wattage is how powerful a charger is. It is worked out by multiplying volts (V) by amps (A). So a 5V/2A charger is 10 watts. The greater number of watts on a charger, the quicker your phone may charge. Your phone however regulates what power it receives. So, using a 65W charger on a 18W supported phone will not provide you with lightning speed. Your phone will only use what it is capable of.
Common Wattage Rates of Phone Chargers
Chargers are available at various capacities. Older ones provide 5W, which is extremely slow for smartphones today. Mid-range ones provide 10W to 18W and are typically available for newer phones. Fast ones provide 20W to 45W, such as Apple 20W USB-C, or Samsung 25W. Flagship phones support 65W or even 100W, particularly for high-performance or gaming devices. Just keep in mind, the charger capacity must be compatible with your phone.
Which Wattage is Right for You?
Most contemporary smartphones are optimized for use with 18W to 30W charge capacities. This is what provides quick and reliable charging. The iPhone works well with 20W charging abilities, and Android phones typically are compatible with 25W or greater.
If you only want a single charger for use with both your phone and computer, a 65W charger would be a great choice. However, if your phone does not accommodate high-speed charging, a standard charger will do.
Conclusion
Choosing an appropriate charger’s wattage allows you to charge the phone faster without harming the battery. Make sure you check the charging support of your phone and utilize a charger with the same or a slightly greater level. This is an easy measure that saves time and extends battery life.
