How Many Watts is an iPhone Charger?
When it comes to charging our iPhones, we often focus on finding the right charger that will provide fast and efficient charging. One of the key factors to consider is the wattage of the charger. In this article, we will explore in detail how many watts an iPhone charger typically has, why it matters, and what you need to know to make informed decisions about charging your device.
Understanding iPhone Charging
Before we dive into the specifics of iPhone charger wattage, let’s briefly understand how iPhone charging works. iPhones utilize a lightning connector, which is the primary means of charging the device. The charger itself connects to a power source, such as a wall outlet or a USB port on a computer or power bank.
When plugged into a power source, the charger delivers electrical current to the iPhone’s battery, replenishing its charge. The charger converts alternating current (AC) from the power source into direct current (DC) suitable for the iPhone. This conversion process is crucial for ensuring that the charging is safe and efficient.
Standard iPhone Charger Wattage
The standard iPhone charger typically has a wattage of 5 watts (W). Apple ships the iPhone with a 5W power adapter, which has become the default charger for many iPhone models over the years. This charger provides a modest yet reliable charging speed. However, it’s essential to note that not all iPhone models come with the same wattage charger out of the box.
iPhone Charger Wattage by Model
Here’s a breakdown of the wattage for different iPhone models:
- iPhone 12 Series: The iPhone 12 series supports the fastest charging speeds available. However, these models are not shipped with a charger.
- iPhone 11 Series: The iPhone 11 series supports fast charging but only includes a 5W charger in the box.
- iPhone XS, XR, X: These models also support fast charging but are bundled with a 5W charger.
- iPhone 8 and earlier: These models come with a standard 5W charger.
Charging Speed and Wattage
Now that we know the standard wattage for iPhone chargers let’s discuss how it affects the charging speed. The wattage of a charger plays a significant role in determining how fast your iPhone charges.
The rate at which your iPhone charges is measured in amperes (A). The formula to calculate the charging speed is as follows:
Charging Speed (A) = Charger Wattage (W) / Voltage (V)
The standard voltage for iPhone charging is 5 volts (V). Using this information, we can determine the charging speed for different iPhone charger wattages:
- 5W Charger: Charging Speed = 5W / 5V = 1A
- 10W Charger: Charging Speed = 10W / 5V = 2A
- 18W Charger: Charging Speed = 18W / 5V = 3.6A
From the calculations above, we can see that a higher wattage charger delivers a faster charging speed. However, it’s important to note that the charging speed may also depend on other factors such as the iPhone model, battery health, and charging cable quality.
Benefits of Higher Wattage Chargers
While a standard 5W charger can effectively charge your iPhone, there are several benefits to using higher wattage chargers:
- Faster Charging: If you’re in a hurry and need to charge your iPhone quickly, a higher wattage charger can significantly reduce charging time. With a 10W or 18W charger, you can experience noticeably faster charging speeds.
- Compatibility with Other Devices: Higher wattage chargers, such as those that come with iPad models or certain MacBook models, can also be used to charge your iPhone. This versatility can be convenient if you own multiple devices and want to interchange the chargers.
- Future-Proofing: Investing in a higher wattage charger ensures that you’ll be prepared for future iPhone models that may support even faster charging speeds. By having a compatible charger, you can maximize the potential charging capabilities of your device.
Choosing the Right Charger
When selecting a charger for your iPhone, consider the following factors:
- Charging Speed: If fast charging is a priority for you, opt for a charger with higher wattage. A 10W or 18W charger can significantly reduce charging time compared to the standard 5W charger.
- Compatibility: Ensure that the charger you choose is compatible with your iPhone model. Apple provides information on the recommended chargers for each iPhone model, so cross-reference this information before making a purchase.
- Certifications and Safety: Look for chargers that meet industry safety standards and have relevant certifications, such as UL certification. This ensures the charger is reliable and won’t pose any safety risks during charging.
Summary
In conclusion, the standard iPhone charger typically has a wattage of 5 watts. Higher wattage chargers, such as 10W or 18W, offer faster charging speeds. While the standard charger is sufficient for most users, opting for a higher wattage charger can provide convenience and future-proofing benefits. When choosing a charger, consider factors like charging speed, compatibility, and safety certifications. By understanding the wattage of an iPhone charger, you can make informed decisions to enhance your charging experience.

Frequently Asked Questions
What is the wattage of an iPhone charger?
The wattage of a standard iPhone charger is 5 watts.
Can I use a higher wattage charger for my iPhone?
Yes, you can use a higher wattage charger for your iPhone. Apple devices are designed to support higher wattages, so you can use an iPad charger (10 or 12 watts) or even a MacBook charger (29, 61, or 87 watts) to charge your iPhone. However, keep in mind that using a higher wattage charger will not necessarily make your iPhone charge faster, as the device will only draw the amount of power it needs.
Is it safe to use a lower wattage charger for my iPhone?
Yes, it is safe to use a lower wattage charger for your iPhone. The device will only draw the amount of power it needs, so using a lower wattage charger will not cause any harm. However, it may result in slower charging times compared to using a charger with the recommended wattage.
Can I charge my iPhone with a USB port on my computer?
Yes, you can charge your iPhone with a USB port on your computer. USB ports typically provide 2.5 watts of power, which is sufficient to charge an iPhone. However, the charging time may be slower compared to using a wall charger with a higher wattage.
Does the wattage of a charger affect battery life?
No, the wattage of a charger does not directly affect the battery life of your iPhone. The charger simply provides the necessary power to charge the battery. However, using a higher wattage charger may result in slightly faster charging times, which can indirectly impact battery life by reducing the overall time the battery spends connected to a charging source.
Final Thoughts
An iPhone charger typically has a wattage of 5W or higher, depending on the model and version. The charger that comes with the iPhone is usually a 5W charger, which is designed to provide enough power to charge the battery efficiently. However, newer models like the iPhone 8 and later support fast charging with a higher wattage charger, such as 18W or 20W. It’s important to note that using a charger with a higher wattage than what your device supports may not necessarily result in faster charging. It is always recommended to use the charger provided by Apple or a certified third-party charger to ensure compatibility and safe charging. So, if you’re wondering how many watts is an iPhone charger, it can vary but generally starts at 5W.
