1.5 meters above the line is a magnetic ring. Single magnetic ring. 0.3 meters and 0.5 meters is no magnetic ring. This must be explained
Magnetic ring is the role of anti-electromagnetic interference to reduce the transmission loss.
As the line longer, power supply data transmission and other losses began to increase, especially after more than 3 meters, the signal and power supply has been attenuated.
If it is connected to the kind of voltage and current requirements of relatively high equipment, such as some mechanical mobile hard drives, printers, etc., it is recommended that buyers of external power supply equipment.
This extension line more than 1.5 meters after charging is relatively slow, not suitable for wireless card, nor suitable for mobile hard disk, because most of the mobile hard disk on the current requirements are high.
1. High purity nickel plug, reduce data loss, error signal;
2.USB female all-inclusive design, anti-oxidation, anti-interference, multi-layer shielding;
3. Plug used 24 hours salt spray test (nickel), improve product anti-salt spray corrosion resistance, increase product life;
4. Wire core conductor with high quality oxygen-free copper, increase the product signal transmission surface, extend product life;
5. Use high-quality data lines (unique signal line twist way): braided encryption, triple shield, faster transmission;
6. The use of wear-resistant non-toxic environmentally friendly rubber compound, delicate and transparent blue, more clearly see the inner quality;
7. Support multi-operating system, compatibility: Windows8 / 7/10 / Vista / XP / 2008/2003/2000/98 / Mac / Linux
