Although the data cable transmission rate and the thickness of the original itself is not much contact, but to some extent also be influential. On the transmission efficiency, mainly by the line of materials and design process, and now on the market to provide a lot of choice of products, with different materials will also affect the transmission efficiency of the different. While the thickness and length of the line played a secondary effect, the size of the diameter of the current will have an impact, wire and resistance will have an impact, so the actual choice of products when the need for a comprehensive consideration of the coordination will be better.

If long-term is not fully charged to start using the battery, then the battery power will be significantly decreased, even if the future is also full of dissatisfaction with the full. Therefore, the maintenance of nickel-metal hydride battery is an important way: electricity must be used to start charging, full of electricity before they are allowed to put into use. Now commonly used lithium battery memory effect can be small to negligible.

Lithium batteries long-term (more than three months) do not use, will produce electrode material passivation, battery performance decline, you can use three full charge, fully discharged to remove purification, play the highest performance of the battery.

1, the new battery: without any treatment, such as activation, can be directly put into normal use.
2, idle battery (within three months): without any treatment (such as activation, etc.) can be directly put into normal use.
3, idle a long time of the battery (more than three months): do activation processing, making the battery activity to achieve the highest, can not do so with normal use of natural recovery to the highest activity.

     Physically, the Type-C port and connector are about the same size as those of the Micro-B USB mentioned above. A Type-C port measures just 8.4 by 2.6mm. This means it's small enough to work for even the smallest peripheral devices. With Type-C, both ends of a USB cable are the same, allowing for reversible plug orientation. You also don't need to worry about plugging it in upside down as it will function both ways.

Since 2015, USB-C has been widely adapted and used in many phones and tablets. Many new storagedevices also use USB-C ports instead of a USB-B port. Almost all devices that support USB 3.1 use the USB-C port. USB 3.1 has a top speed of 10Gbps and can deliver a power output of up to 20 volts (100 watts) and 5 amps. When you consider most 15-inch laptops require just around 60 watts of power, this means in the future they will be charged the way phones are now, via their little USB port. Apple's newMacBook has just one USB-C port as the sole peripheral and power port.

Type-C USB also allows for bi-directional power, so apart from charging the peripheral device, when applicable, a peripheral device could also charge a host device. All this means you can do away with an array of proprietary power adapters and USB cables, and move to a single robust and tiny solution that works for all devices. Type-C USB will significantly cut down the a amount of wires currently needed to make devices work.
