As technology advances, our devices are becoming increasingly power-hungry. To keep up with the demand, manufacturers are producing higher-wattage chargers that can quickly top off our batteries. However, this raises an important question: can you use a lower-wattage charger instead of the recommended one? In this article, we’ll explore the possibility of using a 90W charger instead of a 135W charger and what implications it may have on your device.
Understanding Charger Wattage
Before we dive into the main topic, it’s essential to understand how charger wattage works. The wattage of a charger determines how much power it can deliver to your device. A higher-wattage charger can charge your device faster, but it also depends on the device’s capabilities. Most modern devices, especially laptops and tablets, require higher wattage to charge quickly.
The wattage of a charger is calculated by multiplying the voltage and current. For example, a 135W charger might have a voltage of 20V and a current of 6.75A. This means that the charger can deliver 135 watts of power to your device.
Device Compatibility
When it comes to using a lower-wattage charger, device compatibility is crucial. If your device is designed to work with a 135W charger, using a 90W charger might not be the best idea. Here’s why:
- Charging Speed: A lower-wattage charger will charge your device slower. This might not be a significant issue if you’re charging your device overnight, but it can be a problem if you need to top off your battery quickly.
- Power Delivery: Some devices require a certain amount of power to function properly. If the charger can’t deliver enough power, your device might not work as expected.
However, if your device is designed to work with a lower-wattage charger, using a 90W charger instead of a 135W charger might not be a problem.
Pros And Cons Of Using A 90W Charger Instead Of A 135W Charger
Here are some pros and cons to consider:
- Pros:
- A 90W charger is generally smaller and lighter than a 135W charger, making it more portable.
- It might be cheaper than a 135W charger.
- Cons:
- It will charge your device slower.
- It might not be compatible with all devices.
Heat Generation
Another important factor to consider is heat generation. A lower-wattage charger might generate less heat than a higher-wattage charger, but it depends on the charger’s design and quality.
A well-designed charger with a lower wattage might generate less heat than a poorly designed charger with a higher wattage. However, in general, a higher-wattage charger will generate more heat due to the increased power delivery.
Conclusion
In conclusion, using a 90W charger instead of a 135W charger depends on your device’s compatibility and your charging needs. If your device is designed to work with a lower-wattage charger, using a 90W charger might not be a problem. However, if your device requires a higher wattage to charge quickly, using a 90W charger might not be the best idea.
It’s essential to check your device’s manual or manufacturer’s website to determine the recommended charger wattage. Additionally, consider the pros and cons of using a lower-wattage charger, including charging speed, power delivery, and heat generation.
By understanding the implications of using a lower-wattage charger, you can make an informed decision that meets your charging needs and keeps your device safe.
What Happens If I Use A 90W Charger Instead Of A 135W Charger?
Using a 90W charger instead of a 135W charger will not cause any damage to your device. However, it may affect the charging speed. The 90W charger will charge your device, but it will take longer to reach full capacity compared to using the recommended 135W charger.
The impact on charging speed will depend on the device’s power requirements and the charger’s capacity. If your device requires a high power input to charge quickly, using a lower-wattage charger will result in slower charging times. However, if your device can adapt to different power inputs, the difference in charging speed may not be significant.
Will Using A 90W Charger Instead Of A 135W Charger Affect My Device’s Battery Life?
Using a 90W charger instead of a 135W charger should not affect your device’s battery life. The battery life is determined by the number of charge cycles, depth of discharge, and overall usage patterns. The charger’s wattage does not directly impact the battery’s lifespan.
However, it’s essential to note that using a charger with a lower wattage rating than recommended may cause the device to heat up more during charging. Excessive heat can affect the battery’s health and longevity. But in most cases, using a 90W charger instead of a 135W charger will not cause significant heat buildup.
Can I Use A 90W Charger To Fast-charge My Device That Requires A 135W Charger?
You can use a 90W charger to charge your device, but it may not support fast charging. Fast charging requires a specific power output, and using a lower-wattage charger may not meet this requirement. If your device requires a 135W charger for fast charging, using a 90W charger will likely result in standard charging speeds.
If you need to fast-charge your device, it’s recommended to use the recommended 135W charger. However, if you don’t need fast charging, a 90W charger can still charge your device, albeit at a slower rate.
Will Using A 90W Charger Instead Of A 135W Charger Cause My Device To Overheat?
Using a 90W charger instead of a 135W charger should not cause your device to overheat. The charger’s wattage rating is not directly related to the device’s temperature during charging. However, if the 90W charger is not designed for your device or is of poor quality, it may cause overheating.
To minimize the risk of overheating, ensure that the 90W charger is compatible with your device and is from a reputable manufacturer. Also, keep an eye on your device’s temperature during charging, and if it becomes excessively hot, discontinue use.
Can I Use A 90W Charger To Charge My Device That Has A 135W Charging Port?
Yes, you can use a 90W charger to charge your device, even if it has a 135W charging port. The charging port’s wattage rating is the maximum power it can handle, but it can still accept lower wattage inputs.
However, keep in mind that using a lower-wattage charger may not take full advantage of the device’s charging capabilities. If you want to charge your device quickly, it’s recommended to use a charger that matches the device’s recommended wattage rating.
Will Using A 90W Charger Instead Of A 135W Charger Void My Device’s Warranty?
Using a 90W charger instead of a 135W charger should not void your device’s warranty. The warranty is typically tied to the device’s usage and maintenance, not the charger’s wattage rating.
However, if you’re using a third-party charger that’s not certified by the manufacturer, it may void the warranty. Always check with the manufacturer to ensure that the charger you’re using is compatible and certified for use with your device.
Can I Use A 135W Charger To Charge My Device That Requires A 90W Charger?
Yes, you can use a 135W charger to charge your device that requires a 90W charger. The device will only draw the power it needs, and the excess power will not be used.
However, using a higher-wattage charger than recommended may not provide any benefits, and it may even cause the device to heat up more during charging. But in most cases, using a 135W charger to charge a device that requires a 90W charger will not cause any issues.
