Some people asked this question in the forms on the site, if it is possible to use any charger to power the smartphone’s battery, it is in this article that I will bring the answer to the question.
The straight answer I give is, yes, you can use any charger. standard FOR SMARTPHONE, on any SMARTPHONE, as long as, obviously, the charger fits your cell phone. Read default loader all that are not TURBO ou FAST CHARGER. But wait, let’s talk about the technical part yet, about car chargers and USB cables connected directly to the computer.
Can I charge my smartphone with another charger?
Can I use another charger on my cell phone?
There was a time when cell phone chargers were practically all different, including within the brand itself, to prevent the device from spoiling, it was necessary to make sure that the charger and the phone had the same voltage (voltage) and current (amperage).
To solve this problem, the companies got together in 2007 and created a USB charging standard. As a result of this union, as of that date, all devices came with a USB charger that could be used between devices. So feel free to use any standard cell phone charger no your mobile phone.
Before going a little deeper into the subject, I want to bring an analogy to understand what voltage is and what current is. Voltage is measured in volts.the more volts, the more energy can flow. Current is measured in amps.is the flow of energy that enters the cell.
An analogy we can make is, imagine a road, doubling the number of lanes, it is possible to double the vehicle traffic, without increasing their speed. That is, if I increase the voltage, more energy will flow, but it will maintain the same energy flow.
USB vehicle charger, can I use it without fear?
I mentioned above that you can fearlessly use cell phone chargers on any cell phone. However, a vehicle charger, which we buy for BRL 10.00 to BRL 15.00 from street vendors, is not always measured by the inspection bodies, and they are the main causes of problems. People buy and use them without fear of being happy, they simply plug them in their cars and stick them in their cell phones. Let’s see here that it’s not always good to do this.
What precautions should we take when buying a vehicle charger?
Before buying, it is necessary for you to check the voltage (voltage), this is the main factor. The devices today work with a voltage of 5.0v. You cannot provide more than 5 volts, this can make the cell phone burn or even explode. The current, measured in amperes, you don’t have to worry too much, since the device itself has a voltage controller. The normal current that the cell phone needs is 2 A. So, if the charger sends 4 A of current, the cell phone will control to input only the 2 A it needs. If you send 1 A, the cell phone will “pull” this 1 A, but it will take longer to charge.
Below we have a traditional vehicle charger, see that it has two outputs, one of 1 A and the other of 2 A. The top one will take longer to charge than the bottom one.
Why does it take longer to charge with less current?
Imagine a faucet, if I have a faucet closed, the water flow is zero, but I still have pressure inside the pipes. The stream is provided when we open the tap, for washing hands I need a small stream, I open the tap a little. To fill a pool I would probably open the faucet all the way to consume all the pressure and fill it faster. Now if the water pressure is low, I will also fill the pool, but it will take longer. This analogy you can use to charge your cell phone. If you use a current of 1 A, the cell phone will take longer to charge than that of 2 A. If the current is greater than 2 A, the device will not use all of it, due to the 2 A limit.
So check if the car charger has 5Vif you have it, you can buy it.
It is common to use the device in the car as a GPS, which consumes a lot of energy. It is necessary that you connect the cell phone to the 2 A output, so it will handle the use and charge the device at the same time.
Charge on the computer’s USB, does it charge faster?
Now that you know how voltage and current work, let’s get started. USB 2.0 provides only 0.5 A, and 3.0 provides 0.9 A. That is, USB 3.0, the ones with the blue pin, charge faster than 2.0. However, USB still charges slower than a wall charger, which supplies 2 A of current. Read: Is it true that charging the cell phone on the PC’s USB takes longer?

TURBO chargers, can I use it on my cell phone?
The TURBO or FAST CHARGER chargers have control of several outputs. Today we already have 200W chargers, which in addition to being able to send all that charge to a compatible smartphone, it is also capable of sending less energy in different capacities, thus being useful for other devices and smartphones.
Concluding
Yes, you can safely use any standard charger. TURBO or FAST CHARGER must have a standard output for correct use.
Some tips:
Always use good cables and chargers, from reliable manufacturers, do not buy from street vendors. If using another charger, make sure it has the same output volts, same voltage. If the current (amps) of the charger is low, turn off the device to optimize the charging rate. If you need to use the device intensively while charging (in the car, with GPS and bluetooth turned on), it is mandatory to comply with at least the number of amps of the original charger, otherwise it will just let the device discharge more slowly.
