With the popularity of smartphones, tablets, and even traffic recorders, GPS navigators, etc., USB charging cables have become common consumables and USB gifts. However, when our original data cable is damaged or lost, we have to buy new one, but the charging speed of the newly purchased cord becomes so slow.
The fundamental reason is the difference in USB charger lead design specifications. Even if some manufacturers tell you that they can provide original data cord, sometimes they are still not compatible. Wire is the bridge between the power supply and the equipment. Based on the "transmission loss" effect, you may have to pay attention to some details.
High quality USB charger cable will be produced according to UL and CSA specifications. You can also find the corresponding information on the wire.
Each of the USB cord signal lines is made up of many small soft copper wires, tinned soft copper wires, etc. For example, 20AWG is inserted into 20 wires, and 10AWG is only 10 wires. Relatively speaking, each of the 10AWG wires has a relatively large diameter and a cross-sectional area naturally larger than 20 AWG. The wire diameter of these small wires is proportional to the amount of current that can be carried, that is, the thicker the higher the bearing capacity.
For the general application of USB wire, the AWG value can withstand the amount of passing current is necessarily higher, the key is the cross-sectional area.
Choice suggestion: worthy of carefully selected USB charger lead.
1. The smartphone is recommended to select at least 26AWG specifications, and the tablet is based on 24AWG. However, it should be noted that the power source terminal such as USB charger and mobile power supply has a larger output current specification than the device design input current, so it is meaningful to purchase a high-standard USB cable.
2. If the appearance of the wire of the same specification is different, then in theory it is better to be thicker. Regardless of the fact that the counterfeit goods are not used with the corresponding specification wires, the same specifications are different in thickness, and the products with thinner wires may be simplified by the isolation layer. Even if this does not affect the power transmission effect, the bending durability may be slightly affected.
3, choose the appropriate length, if the daily application has a variety of different length requirements, then choose a different length of USB cable number line, easy to use
SINODEC can provide 18AWG, 20AWG, 22AWG, 24AWG, 26AWG, etc different USB charging and data sync cable according to customer's requirements. Of course, we can also provide high quality USB charger cable according to customers' color, length and material.
