45W USB-C Charger

Yes, it is generally safe to use a 45W charger on a phone. Most phones have built-in charging circuitry that regulates the charging speed to prevent damage to the battery. This means that your phone will only draw as much power as it can handle. Nevertheless, it is vital to choose compatible chargers from renowned brands like Anker 713 Charger (Nano II 45W) to ensure universal compatibility and safety.

The main difference between a 25W and a 45W charger is the wattage. A 25W charger delivers 25 watts of power, while a 45W charger delivers 45 watts of power. This means that a 45W charger will charge your device faster than a 25W charger. For example, the Anker 313 Charger (Ace, 45W) can fully charge a Galaxy S23 Ultra within an hour.

Using a 45W charger with a device that supports it will not damage the battery. Modern devices are designed to handle various charging speeds safely. Therefore, the device will generally only draw the amount of power it requires. This said, it is still essential to use a charger from reputable brands to ensure optimal compatibility and reduce any safety hazards during charging.

Similar to the case of USB hubs for laptops, A 45W USB-C charger can charge your laptop via a cable (such as a USB 2.0 cable) if your laptop supports USB-C charging and has a power requirement of 45W or less. For example, the Anker 713 Charger (Nano II 45W) can handle the task of charging a 2020 MacBook Air pretty well. However, for more power-hungry laptops that require more than 45W of power, a 45W charger may not deliver the best possible performance. This is also why Anker has made higher-wattage chargers too.
