Summary
Fast charging technology allows devices to charge faster than standard charging speeds, resulting in a warmer charge.
1
To ensure a safe and efficient charging experience, it is important to use high quality chargers and cables with all relevant certifications.
1
Fast charging is also possible with older models, but with the right equipment, it is safe to use.
1
For fast charging, manufacturers bump the voltage up from 5V to 9V or 12V and beyond, or increase amperage to 3A and above.
2
The introduction of USB-C helps accomplish this with support for up to 100W and 20V, which makes faster charging speeds possible.
2
A fast charger outputs up to 15 watts, and a super-fast charger more than 15 watts.
3
The more watts, the faster the charge, but only up until to reach the limitations of your phone.
