Can I Use a Charger with Higher Voltage for My Phone?

In today's fast-pace, where it's important to always keep your phone charged no matter where you go, you'll often be put into situations where you need to charge your phone from different power sources. Hence, it's important for you to understand that a phone impacts both your device's charging speed and its safety. Let's take a deep in for how you can charge your phone safely at different voltages, and tips that'll help you maintain your phone health.

How Voltage Affects Charging and Your Device's Safety

Voltage essentially refers to the pressure from an electrical circuit that pushes the electrons through a conducting loop, allowing your device to charge. The standard voltage for phone chargers typically ranges around 5V, but with advancements in technology, many modern devices can handle higher voltages like 9V or even 12V for faster charging, thanks to technologies like USB Power Delivery (USB-PD).

Can I Use a Charger with Higher Voltage for My Phone?

Using a charger with higher voltage can be tempting as it promises quicker charging times. However, it's imperative to use a charger that matches the specifications recommended by your device’s manufacturer. Modern smartphones are equipped with smart circuits that recognize and regulate the incoming voltage, but exceeding the device’s maximum voltage capacity can lead to overheating, battery damage, or worse.
