1. Over the years, you may have collected all kinds of chargers for mobile phones, tablets, notebooks and other devices in your home. We have all heard that using the wrong charger will lead to the explosion of mobile phones. So how can we judge which charger is safe for each device?All this should be attributed to voltage. Although using mobile USB charger can protect our mobile phones, it is not always so convenient in life.

2. Is voltage or amperage really that important?
In fact, when charging our mobile phone or notebook, voltage is really very important. If you don't use the original charger for your mobile phone or notebook at present, then you should ensure that the charger you currently use is compatible with the voltage and current of your mobile phone or notebook, If the voltage on the charger exceeds the voltage required for charging your device, you should pay attention at this time. The charger you use is likely to burn your device.

3. Finally, you should know that amperage is as important as voltage, and even amperage is more important than voltage. Amperage is the current supplied to the device to regulate the power flowing from the power supply to the device. If you want to charge your mobile phone or notebook correctly, Then the amperage on the charger or power supply should match or exceed the power required by your current device.
