## What is a 5V 2A power adapter?

DC 5V/2A, means that the input voltage, to recharge the battery is 5 volts of direct current. … It has two outputs, one 2.1A USB (for tablets and Raspberry Pi and high-current devices, the other 1A USB for phones and smaller devices.

Can I use 5V 2A adapter?

The adapter works perfectly if the rated value is stated on it. If you use 5V 2A for the use of 5V 1A, it will work. There will be a dip in the output voltage if you operate a load of 2.5 A rated value.

Can I use a 5V 2.4 a charger with a 5V 2A device?

Yes, it is absolutely safe to charge a device with a charger that has more current capacity than needed. Since the voltage is held constant (5V), the only factor that determines current draw is the load (another term for resistance) the device places on the charger.

### Are phone chargers 5V 2A?

There are basically three kinds of charger plugs, the Android phone plug is a Micro USB interface and a Type-C interface, and the Apple mobile phone is a Lightning interface. For most smartphones, the charger’s output specification is 5V/1A, or 5V/2A.

What is 5V 2A Watts?

#### Are Iphone chargers 5V 2A?

Apple’s chargers only go up to 5V, which is within the USB standard. So yeah, it’s all good and safe. The current/voltage comments regarding the iPad charger is incorrect. It supplies 5V @ 2A.

What does 5V 2A mean?

DC 5V/2A, means that the input voltage, to recharge the battery is 5 volts of direct current. 2A is the amount of amperage that is suggested to recharge the battery. This dose not mean that a transformer of lesser amperage won’t charge it it would just take longe.

Can I use a 5V 2A charger with a 5V 4A device?

Originally Answered: The charger given for me is 5V/2A , Can I use a 5V/4A charger for my device? No, you cannot use that because it is actually exceeding the current rating.
