Five Steps to Choosing the Right Fast-Charging Setup

“Does a higher-wattage charger mean your phone will charge faster? Not necessarily!”

Many people assume that a 65W or 100W charger will automatically charge their phone faster. However, the actual charging speed depends mainly on the maximum charging power supported by the phone.

So, before buying a charger + charging cable, don’t just look at the wattage. Check these 5 key points to make sure you choose the right combination.

Step 1|Check How Many Watts Your Phone Supports

First, check the maximum charging power (W) supported by your phone. For example, if your phone supports up to 45W, there’s no need to specifically buy a 100W charger.


Step 2|Check the Charger’s Output Power

Make sure the charger provides enough output power. For example, if your phone supports 45W fast charging, choose a charger that supports 45W or higher.


Step 3|Check the Charging Cable’s W and A Ratings

Charging cables also have power limits. Common specifications include 60W, 100W, and 240W, as well as 3A and 5A ratings.

Don’t assume that a USB-C cable automatically supports fast charging just because it uses a USB-C connector.


Step 4|Check Fast-Charging Protocol Compatibility

For example, USB PD (USB Power Delivery) is a widely used fast-charging standard. To achieve the expected charging speed, both the charger and the phone need to support compatible fast-charging specifications.


Step 5|Make Sure All Three Components Work Together

The final step is to check the phone, charger, and charging cable as a complete setup.

The easiest way to understand it is:

The phone determines how much power it can accept; the charger provides the power; and the charging cable delivers the power.
