Over years, the length of the charging cables is getting reduced seemingly. And now, 1-meter is considered an ideal length of charging cables. Well, why is this happening? Has it anything to do with the charging quality? Apparently, the length of the cable can make a real difference.
Let’s counter your questions one by one.
One thing that we all know for sure is that quality charging is important for the battery of your mobile devices and so the charging cables. Let’s take cables, for instance.
Does the Length of Charging Cables affect the Charging Speed?
Yes, it does.
Because it affects:
- Current Carrying Capacity: It is determined by the size of the conductor and the thermal heating of the cable. Besides, insulation materials, cable spacing and application also contribute to heat dissipation.
- Voltage Regulation: Voltage drop occurs because wires have resistance, and it is connected to Ampacity, a cable’s electric current-carrying capacity. VD is particularly a problem with long cables as when the length of the cable increases, so does its resistance. And reactance increases in proportion. When current runs through DC resistance, it causes a voltage drop.
- Short Circuit Rating: It’s the capability of a cable to withstand maximum current in a short circuit condition. The cable should withstand short circuits without thermal damage until it gets fixed.
Apparently, all these conditions speak in favor of a short-length cable. The speed of the charging will be determined by amperage supply.
Why Buy 1 M Long Charging Cable?
If you are a fan of fast charging or often run low on time, you need to ensure that the cable and adapter you use support fast charging. But before that, let’s dispel the popular myth that faster-charging damages your phone battery. Nothing such happens if you are using a quality cable. Rather the charging capability depends upon various other factors that are discussed in our latest blog.
Short Charging Cables Charge Faster than Long Cables
Well, we have a mechanism working behind it. The length of a cable and the speed at which it supplies power to your smartphone depends upon the resistivity.
Resistivity = Length / Cross Sectional Area
Resistance Decides the Quality of Charging – The Longer the Wire, Greater The Resistance.
The more the power goes through the charger, the faster the charging it delivers. When the electricity passes through the charging cables, electric conductors in it offer some resistance. The level of resistance is decided on the basis of:
- The length of the wire/conductor.
- The gauge/thickness/cross-sectional area of the wire.
Decrease the Dangers of Radiations Exposure
We all know that our cell phones emit radiation while charging. But some of us are so eager to use it that we use it even knowing that it’s harmful. Various cellphone incidents are noted till date due to usage while charging. To counter this, the length of charging cables is getting reduced. Besides, holding the device farther away from your ear can reduce exposure to radiation drastically. Whilst a lengthy cord might allow you to use your device while charging, but it will eventually slow down the charging progress to delay it further.
Shorter USB Cables Are Less Likely To Tangle
Whether you are clumsy or organized, tangled cables are always a mess. Tangled up are always at the risk of getting ripped or broken. Also, the tangle-detangle process takes time. While shorter cords are less flexible and provide no scope for tangling, large cables tend to get twisted regularly. Since the cable is short, your phone is less likely to be used while on charge to avoid the unwanted tug of war. Short cables are chic and easy to carry. Pick your short charging cable as per your device (Lightning, USB Type-C and Micro USB) and enjoy effortless charging.
Conclusion
Humans are really impatient and want their mobile devices to get charged at the earliest. Earlier average chargers used to take 3-3.5 hours to fill a device to 100%. But now, thanks to Quick Charge/Fast Charge technologies, we can get it full in just 45 minutes to 1 hour. If you want a moderate to fast charging cable, go for medium thickness, a short length and functionality-focused cables.
