Hardware|Batteries & Chargers|Wall Chargers

In phone charging - for example - wattage represents the rate of energy transfer - essentially how much "juice" can flow into your battery at once. While higher wattage usually means faster charging, the speed is ultimately controlled by your phone's internal circuitry, which will only draw the maximum power it is designed to handle.

For a standard smartphone battery (4,000–5,000 mAh), a 100W charger is primarily used for ultra-fast charging of supported flagship devices or for powering multiple items at once. While most phones cap their intake at lower wattages, devices specifically designed for 100W+ charging can reach a full charge in roughly 17 to 20 minutes.
