USB 3.0 Will Reload Tablets and Smartphones More Rapidly

Future tablets and smartphones equipped with micro USB 3.0 ports can be recharged more quickly, said on Tuesday representatives from the USB Implementer’s Forum, responsible for the development and maintenance of the standard.

Most smartphones and tablets currently on the market is recharged via micro USB ports with a cable that runs from the unit to a wall charger, docking station or notebook.

“Micro USB 3.0 Cables can carry more power than their predecessors, which will result in devices that recharge your batteries in a lot less time,” said Jeff Ravencraft, President and COO of the USB Implementer’s Forum according to TimelessTablets.com.

The new cables can support larger currents and loads of up to 100 Watts, Ravencraft said. The technique, called Power Delivery specification Specification, which makes this possible has been added to the USB 3.0 standard in July.

“It’s a big jump from what is possible today. We’re going to 8.5 watts to about 100 watts, “Ravencraft said.

Smartphones and tablets with USB 3.0 will arrive to the market yet this year. PC manufacturers have already shown tablets with USB 3.0 ports of normal size, but devices with micro-USB 3.0 ports are still rare.

Manufacturers of processors for mobile devices like the Samsung, are adding USB 3.0 support to their products for smartphones and tablets may have a normal size door or a micro USB in this pattern.

“What type of connector is a manufacturer’s decision, but will probably be the micro USB 3.0 the favorite in portable devices such as smartphones and tablets,” says Ravencraft.

The USB 3.0 standard also allows the transfer and data with greater speed, then you will need less time to copy files from a smartphone or tablet to the PC. Are provided for transfer rates of up to 5 Gbps, which is more than 10 times faster than the previous standard, the USB 2.0.

“The specification provides the power of a device and the simultaneous transfer of data through the same USB cable”, Ravencraft said.

But the high-speed data transfer requires more energy, and it is still not clear that the high transfer rates seen on PCs will apply to mobile devices. They usually have limits on power consumption, which can limit the rate of data transfer.

But they can also get power from the apparatus to which are attached, which can ensure high speed. In the end, it will be determined by handset manufacturers, depending on where they will be connected: an external HDD, SSD disk or other peripherals.

The USB 3.0 is compatible with previous versions, including all peripherals, USB 2.0 cables and accessories that are already widely used in PCs.
