Frequently Asked USB Questions

How does USB charging work?

When it comes to USB charging there is always one host and one device, power comes from the host (ie: PC) to the device (ie: mobile phone) and data carries freely between them both. A USB cable contains 4 wires and a USB socket contains 4 pins. The pins on the the outside provide a 5v power supply while the inside pins carry data.

Is USB charging slow?

This all depends on the USB charging sockets amperage. iPads typically require around 2.1amps to charge but a smartphone would only need around 1.0amp. Our new TUF-R® A+C USB charger offers different supply voltages depending on the device being charged. When a device is plugged into either the Type A or Type C socket a digital ‘handshake’ takes place allowing the TUF to charge the device at the optimum level.

Are all USB ports the same?

No, there is one standard and many different connectors. Below is a breakdown of the different types of USB connector.

What is the difference between a phone USB charger and a tablet USB charger?

Tablet chargers generally have a higher rating than phone chargers, check the rating of the chargers, this is to ensure that the output is correct for your device. Just because they have the same physical connection doesn’t mean that the output will be the same. Incorrect charge could mean damage to your device and the potential risk of overheating and fire.
