Can you interchange phone chargers?
As a result, nearly any phone and tablet now comes with a USB charger that can be used interchangeably between devices without any issues. That means that you can feel free to use any of your USB chargers included with your phone or tablet with any other phone or tablet made after 2007 without worry.
Can I charge my phone with higher voltage?
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 you use a 5 volt charger to charge a 3.7 volt cell?
Yes, you can use but monitor the battery voltage time to time if it reached the max like 4.2 v. If it reached there then disconnect it. yes i think you can use 5v charger to charge ur mobile and mobile phones have a regulator which gives a constant volatge that is sufficient for charging a cell phone.
What kind of Charger do you need for a cell phone?
For the cell phone to charge, charger output must be above 4V and can deliver a maximum current of 500mA. This charger circuit will step up the voltage from 1.5V to 5V DC to reach the cell phone charging requirement. The circuit uses only an AA or AAA 1.5v battery (1V to 2.4V).
What should be the voltage of a new Charger?
The voltage provided by your charger must match that expected by the device being charged. When replacing a charger, this is easy to determine: it’ll be listed on the old charger. In your case, the old charger supplied 19 volts, so your replacement must also be 19 volts. It’s very important to get the right voltage.
What should the current rating of a cell phone charger be?
Current rating depends upon the Current requirement of Load circuit (circuit which will use the generate DC). The voltage rating should be more than the required voltage. Means if we need 5V DC, transformer should at least have a rating of 7V, because voltage regulator IC 7805 at least need 2V more i.e. 7V to provide a 5V voltage. 2. Rectification
