About USB Chargers:

multi usb charger - USB chargers are presently the most common devices that are used in charging Smartphones and tablets. The devices are of three main specifications: USB 1.0, 2.0, and three.0. Of the three, USB 2.0 is the most common.

In the USB network, there is always the host and also the device. For example, if you work with computer to charge your phone, you PC becomes the host and you also phone becomes the device.

If you are using a charger, the charger becomes the host along with your tablet or phone becomes the unit. In all times, power flows from your host to the device.

Should you look closely, you will see that a USB socket has four pins. The USB cable even offers four wires. The inside pins carry data (D+ and D-) even though the outside pins provide power.

Charging process:

multi port usb charger - It is great to note that different USB ports charge the devices attached with them differently. For example, you will find that one port charges your phone fast while another port charges the identical phone very slowly.

There's two factors that determine the speed at which your device charges over USB: the most amperage of the USB socket or charger and how your device occupies power from the charger.

All chargers have maximum amperage which is usually between 500 milliamps and 1.5 amps. In most cases a PC has 500mA while the max amperage of a 12v charger varies from one device to a different. Although, this is the case, the amperage of wall chargers is usually between 0.5A and a pair of.1A.

How your device negotiates with the charger greatly determines how your device charges. When you plug your device to the wall charger or charging socket, the USB controller inside your device communicates with the USB controller connected to the charger.

If there is no controller, the unit reads the voltage flowing across the USB pins and from the data the device establishes the amount of amperage that it should draw.

Can a USB device explode during charging?

multi port usb charger - The answer is No. You can plug any USB device into any USB cable and into any USB port with no problems and your device won't explode. This means that you can connect a Smartphone which was included with a 900mA charger in to a 2100mA and the device won't blow up.

According to experts, connecting your device with a higher power source doesn't result to blowing up of the device, but rather speeds up the rate at which the battery charges.
