Can I use a 5V 2A charger with a 9V 2A device?

5 Answers. 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.

Can I use 5V 2A for 5V 1A?

While we know that 5V 2A chargers can charge a smartphone faster than a 5V 1A charger. By simple maths, 5V 2A means 10W – that means double the speed of a 5V 1A charger, right? Unfortunately, that’s not the case.

What amp is fast charging?

2 amps

Is 500mA the same as 0.5 A?

Five-hundred milliamperes (mA) is equal to 0.5 amperes (A), which are also commonly called amps. In the metric system, an ampere is the unit for measuring and representing electric current. One mA is equal to one thousandth of an amp, which can be represented in numbers as 1 mA = 0.001 A.

What is the difference between adapter and charger?

The actual difference between Charger and Adapter is, Charger is an electrical or electronic device which is specially designed to charge a chargeable device such as a battery or a super-capacitor whereas the Adapter is an electrical or electronic device which is specially designed to provide a power supply to an …

How do I know what power adapter to use?

The general rule is to match the V and equal or beat the mAh, so if you are choosing an AC adapter to make sure you check the following, The adapter output V matches the rated input V of the device. The adapter output is greater or equal to the devices rated mAh or A.

Can I use different charger for my phone?

Always charge your phone with its own charger Unlike laptops, smartphones use a universal charging interface the microUSB port. However, if the charger you use does not match the original, it will affect battery performance, capacity to store charge and overall life (if done repeatedly).

Can I use a 5V 2A charger with a 9v 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.

What is 5V 2A or 9V 2A?

The “5V/2A or 9V/2A” output label indicates that the charger supports both 9V/2A fast charging and 5V/2A standard charging. You can also use the charger to charge other phones that support 5V/2A charging standards. Use the standard charger that comes with your Huawei phone for charging.

Can I use 2A charger instead of 1A?

So if you plug a 1A device into a 2A charger, it will still only draw 1A. The rest of the current capacity will be unused. The opposite is also true. If you plug a 2A device into a 1A charger, you will only get 1A.

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.

Is 5V 2A dangerous?

No, 5V will not hurt you. Neither will 12V or even 24V – notice that you can touch both terminals of a 12V car battery without feeling a thing. The 2A (2 amps) part expresses how much current the power supply is able to provide if demanded.

What is the difference between 5V 2A and 5V 1A?

While we know that 5V 2A chargers can charge a smartphone faster than a 5V 1A charger. By simple maths, 5V 2A means 10W – that means double the speed of a 5V 1A charger, right?

Can I use a 5.2 V 2A charger in place of 5V 1A charger?

Can I use a 5V 1A charger to replace a +5.2V 1A charger? Almost definitely yes. Nearly all battery cells operate at below 5 volts, which means your device’s charger circuit is going to chop the 5V or 5.2V down to battery charge voltage (4.2V in modern devices). Your device won’t even notice the difference.

Can you use a 12v 2A charger on a 12v 1.5 a device?

So long as the voltage is the same, and the Amp rating is the same or higher it will work. So your power adapter can supply 12v at up to 1.5 amps.
