FAQ:

Q: Are all USB 5V?

A: All Micro-USB chargers were rated for 5V , so you never really had to worry about accidentally plugging your phone into a charger with too high of a voltage. But now, things are much more complicated. With larger device batteries, new charging technology like Qualcomm’s Quick Charge, and formats like USB-C that allow for better charging throughput, chargers are more complex than ever.

Q: What is an USB power supply?

A: Universal Serial Bus ( USB) is an industry standard that establishes specifications for cables and connectors and protocols for connection, communication and power supply ( interfacing) between computers, peripherals and other computers.

Q: What is the USB voltage output?

A: When a USB device plugs into the USB port, the USB port outputs approximately 5 volts. This means that 5 volts travels from the computer’s USB port through the USB and into the electronic device which consumes it. This is DC voltage .

Q: What is an universal power supply adapter?

A: Universal power adapters are devices that make it possible to connect a power supply to various devices in just about any setting. There are adapters for handheld devices, laptops, and even for various types of household appliances.
