Melissa Forrester When it comes to a USB, people often think of a device connecting and transmitting data at high speed.
More than we expected, now you can use Universal Serial Bus as a power supply to charge electronic devices through USB voltage. But, what is USB voltage?
This article will give the complete and understandable answer for you to follow.

What is USB Voltage?
USB voltage ports usually provide 5V power with a current of 0.5A. This figure can be up to 0.9A in some exceptional cases.
It connects hardware between devices such as scanners, keyboards, mice, hard drives, remotes, cameras, and phones.
The voltage is the connector that plays the role of providing the energy level for the overall operating structure of the device.
The need to charge via Universal Serial Bus is becoming common, and you can easily find power sockets with built-in ports at electronics stores.
How Do USB Chargers Work?
Using a charger to power your phone or computer seems to have become an obvious need in the tech world.
Besides the availability, fast and powerful charging time is a significant advantage that makes users interested in this option.
You can specify the capacity of an instance via “Power Delivery Specs.”
We divide it into main types: USB 1.0, 2.0, 3.0, 3.1 / 3.2, and 4. Accordingly, older versions like 1.0 or 2.0 often do not have optimal charging performance like USB 4. , which is the latest improved version.
The connection network always includes two sides: the host and the device.
In many cases, the PC acts as the server, and electronic items such as computers, phones, or cameras are the devices.
The power will flow from the host to the connected device. However, the data source will move in two parallel directions.
Type-C is a physical upgrade that solves any dilemma. Previously, to charge any device, you needed to make sure the power source was compatible with each one. But this was remedied through the power delivery feature.
Accordingly, you only need to meet the coincidence of the connector cable to be able to charge the battery.
Are USB Threads All The Identical Voltage?
The answer is no. Not all cables have the same voltage.
Sometimes, the total charge time between two identical computers is not the same on the same socket.
All ports are 5 Volt DC. The host device will play the role of converting 122/220 AC voltage into 5 Volt DC for the highest compatibility.
The point of concern here is that the currently available ports are different. Therefore, the charging speed will be different in different devices.
In addition, not all devices can provide sufficient current to perform fast charging. For example, I have a cheap charger in my hand. It can fully charge the phone, but the process won’t be done quickly if I combine multiple functions.

Can I Blow Up The USB?
If you connect the device with a cable with higher amperage, the explosion will not occur. Moreover, it also helps to speed up the charging process.
Host battery life will also be related to the Universal Serial Bus flammability.
In the 2007s, the charging specification standardized the explosion-safe electrical charging technique. And it is also applicable to the present time.
Don’t worry about the problem of exploding. If your device is a new version, connect the socket with a higher amperage for the highest safety.
FAQs
Here are a few related questions to help you see the problem more clearly. Don’t miss this one, as it will probably come in handy in many cases.
Is USB a 12V or 5V?
In terms of popularity, The 5V power supply is the device default. However, the latest generation computers and upgraded versions often need more.
For example, Apple’s computer lines require up to 12V power consumption.
After all, a 5V charging source is often available in many common cases, but if you want, you can still buy a 12V adapter as a backup.

Is USB low voltage?
Yes. Power sources are usually divided into two main parts: voltage and current. The power supply voltage is at a constant voltage.
As mentioned above, each Universal Serial Bus typically provides 5V power, which is relatively low by the standards of many current devices.
How do I get 12 volts from the USB?
Boost converter will help you to upgrade from 5V up to 12V. The sockets have a maximum flow of 500mA. Yet, some particular specifications will help users upgrade to such a higher current, but you need to request an interface chip.
Does USB regulate voltage?
Yes, it does. The charger can regulate the voltage.
The parameter on the Universal Serial Bus is to exist at 5 V across the VCC line. But for some old version lines, throttling is pretty bad.
Can you get more than 5V from USB?
The maximum number the charging adapter can receive is up to 20V, and it can even go up to 48V according to the PC specification.
What does PD 18W mean?
PD power can be up to 18W. The higher this number is displayed, the faster the charging speed will occur. Compared to 5W, when the charging device has a capacity of 18W, the charging power is 2.5 times faster.
Conclusion
Many manufacturing brands focus on the fast charging feature to attract attention from consumers. The faster the charging time, the more current the USB voltage connector must transmit.
For this process, you need a power adapter and a device that needs to provide a charging source. Via this article, you have a good understanding of USB voltage.
