Cable with the thread broke just a few days, charging an hour to 10%, but it also shows how not to come out on the... .. This is when we use the data line often encounter problems. More serious, such as charge their mobile phone bad, rechargeable led to spontaneous combustion, such as accidents are inevitable. How to select a high level and safe data line in appearance, honor or tell you when the choose and buy cable cable factory must pay attention to the five main things.

Note a: charging speed

An hour charge 50% electricity? Or 5 hours to reach 10% charge? See a charging line performance is strong, should see its load current and voltage and the pressure drop, in other words, want to see in an electric current passes through the charging line, capacity is how many, how many wreck, wreck is related to the impedance of the line core. Some fake charging line on the market, the current is not stable, easy to consume mobile phone battery life. Furniture-in cable output voltage and charging current charging line are higher than other brands, and a lower pressure drop, prove electricity flow more wreck less at the same time, stronger performance.

Pay attention to things 2: transmission speed

Some argue that the length of the cable will affect the transmission rate. In fact, within the scope of a certain length, the qualified cable length does not have a large influence for transmission speed, most of the shanzhai charging line only two cores on the market, copper wire or cable using four core, can support data transfer and charging. In addition, the diameter of the line is also will be more or less affect the mobile charging and data transmission speed, if the wire is not good, wire diameter and short, so even the normal length of the cable, its transmission performance is not very good, can appear even cable fever, cause potential safety hazard.
