Q&A:
1. Where does Industrial-grade USB HUB is mainly used?
Answer: This products are mainly for high power mobile terminals (smartphones, tablets, mobile hard disk, digital camera, etc.) of bulk flash, copy the data, the burning procedure, and professional laboratory applications such as data transmission load design under the condition of continuous work.

2. What's the difference between the industrial-grade USB HUB and regular grade?
Answer: Industrial-grade must adopt imported special CPU chip, selection of components, the pursuit of high speed, stability and industrial features, so must depth design, we adopt double protection circuit design, flexible modular design, the vertical way socket and so on. We specially developed special software for bulk copy.

Industrial products of low power consumption, low calorific value, support 8 MiYouXiao data transmission output extension cord, ordinary HUB of only 1.5 meters.

O levels have no import high-performance CPU chip, choose common components, such as no more than industrial characteristic function.

Industrial product USES the high quality USB female copper terminals, wear resistance, no rust, ordinary HUB use iron terminal, more easy to rust.

Industrial-grade products each USB port, dual protection circuit design not because individual USB devices such as short circuit and cause a computer crash or damage to the equipment, ordinary HUB there is usually no circuit protection design, especially the factory semi-finished products testing, often because of individual product short circuit can't lead to problems such as computer disk or crash;

Industrial product modular design, solve the factory batch testing plug is very frequent and lead to the USB port of the wear and poor contact, only need to replace the USB adapter plate head can, do not need to change the new HUB, more cost savings for you; Ordinary HUB is usually high frequency use 1 ~ 2 months later, can lead to poor contact, because of USB port wear new HUB must be replaced and the high cost;

3. Use the product that can recharge the device or IPHONE?
Answer: (1) the product each port to provide 5 v, current 750 ma, in your time limitation of the charging request is not high, can charge, because of the device, the IPHONE must to charge when activate the USB protocol, so the charge must be connected to computer at the same time, and charging current is limited to 500 ma.

(2) when an, the device through the device to connect the computer, the computer is absolutely don't install AI Charger class improve charging current software because this software will raise the charging current to about 1.5 A, completely beyond the power of the equipment can provide, lest cause instability or burn your data transmission products or computer.

4. The product can be for Android phone or tablet (Android) system charge?
Answer: (1) can be on the market at present most of the Android mobile phone or tablet (Android) system, but the charging current is controlled in 500 ~ 600 ma, need not connect the computer;

(2) for the product main function is data transmission, and power restriction, this product does not belong to the professional charger, so the charging time will be needed for a little longer, can only achieve common charging effect.
