Is It Safe to Use Different Voltage in a Charger?
Every cell phone, laptop, and tablet comes with its own charger. Over the years, you might have accumulated quite a few chargers. The question then arises: is it safe to use a charger that isn’t the original manufacturer’s charger that came with your device?
Types of Chargers
We will focus on three types of chargers: laptop chargers, micro USB chargers (used with phones, tablets, and cameras), and Apple Lightning Connectors. While some devices have chargers with slight differences in the charger head or charging cable, these are the most common.
Laptop Chargers
Laptop chargers are specific to the device they come with. However, there may be some generic chargers that claim to be interchangeable between laptops. This often requires changing the charger head, and it might not provide the optimal charging amperage or voltage for your device.
Micro USB Chargers
Micro USB chargers are theoretically designed to be interchangeable and are standard in most smartphones (Android devices) and tablets. These chargers typically have the same voltage but may draw different amps. I'll explain this further and how to know if the charger is safe to use depending on its listed amps and voltage.
Apple Lightning Connectors
Apple Lightning Connectors are standard on all new Apple devices, including iPads and iPods. For older devices with a 30-pin charge port, a connector can be used to charge with the Lightning Connector.
The Voltage Output is Critical
The voltage output is one of the most critical factors and must match your new charger. For example, if you are using a charger with 20V output, you need to look for a replacement charger with matching voltage. By using different voltages, you risk shortening the lifespan of your batteries and your device.
What Voltages to Look For
Chargers are designed to put out a bit higher voltage to ensure that the correct voltage is achieved in the battery or cell. If you use a charger with the wrong voltage, the internal mechanisms of the battery may not function correctly, leading to potential damage.
Checking Compatibility
Before you decide to use a non-manufacturer charger, it is essential to check the charger’s specifications. Most chargers indicate their voltage and amperage (amps) on the charger’s label.
Understanding the Label: The voltage is usually listed as V (volts) and can be 5V, 9V, 12V, 19V, or 20V, etc. The amperage might be listed as A (amps) and can range from 1A to 9A or more. When you have these figures, you can match them with the specifications of your device.
Conclusion
Using a charger with a different voltage can be a gamble. While some newer chargers and adapters are designed to be more compatible, it is still best to stick with the original manufacturer’s charger. If you need to replace a charger, consider purchasing one that matches the exact specifications of your device.
Final Thoughts
Ultimately, the safety and longevity of your device depend on proper charging practices. If you have any concerns or doubts, it is always a good idea to consult the manufacturer’s guidelines or seek professional advice.
