USB chargers are presently the most common devices which can be used in charging Smartphones and tablets. The items are of three main specifications: USB 1., 2., and three.. From the three, USB 2. is regarded as the common. – USB Plug
In the USB network, there is certainly always the host and the device. For example, if you are using computer to charge your phone, you PC becomes the host and you phone becomes the device.
The charger becomes the host and your tablet or phone becomes the device if you are using a wall charger. In every times, power flows through the host for the device.
You will see that a USB socket has four pins if you look closely. The USB cable even offers four wires. The interior pins carry data (D and D-) whilst the outside pins provide power.
Charging process
It’s good to note that different USB ports charge the devices connected to them differently. For example, you will find that one port charges your phone fast while another port charges exactly the same phone very slowly.
There are two factors that determine the rate where your device charges over USB: the highest amperage of the USB socket or wall charger and just how your device takes up power from the charger.
All chargers have maximum amperage which can be usually between 500 1 and milliamps.5 amps. Generally a PC has 500mA while the max amperage of any wall charger varies from one device to a different. Although, this is the case, the amperage of wall chargers is generally between .5A and 2.1A.
The way your device negotiates using the charger greatly determines how your device charges. Whenever you plug your device for the wall charger or charging socket, the USB controller inside your device communicates with the USB controller attached to the charger.
The device reads the voltage flowing across the USB pins and from the data the device decides on the amount of amperage that it should draw if there is no controller.
Can a USB device blow up during charging?
The reply is No. You are able to plug any USB device into any USB cable and into any USB port with no problems along with your device won’t blow up. Because of this it is possible to connect a Smartphone which came with a 900mA charger right into a 2100mA and the device won’t blow up.
According to experts, connecting your device to a higher power source doesn’t result to blowing up of the device, but instead speeds up the rate at which the battery charges. – USB Plug
