Why are phone charger cords so short?

It is because direct proportionality of electrical resistance and length of conductor(cord here). When resistance increases current (charging current) decreases. Thus, increase in length of the wire will result in decrease in the charging current, making the charger inefficient. That’s why short ones are selected.

Does the length of a charger cord matter?

The longer a cable is the more power is converted to heat, so a long cable may limit the charge rate due to excess losses in the cable. However, if you use a quality cable the length of the cable should not become a problem for lengths up to around 6 feet or so.

Why are USB cables so short?

Although standard USB cables typically provide fast, secure data transfer between different devices, they are usually fairly short. This is because standard USB connections begin to lose their effectiveness the longer the distance between each device.

Are long charging cables bad?

Another important factor that affects the smartphone charging speed of a smartphone —which people often overlook— is the length of the cable being used to charge the smartphone. So… yes; the length of your USB cable could either increase or decrease the charging speed (and time) of your smartphone.

Do longer charging cords take longer to charge?

Yes, the longer the cable, the slower the charge if maximum current is being transferred on a given cable size.

Does longer cables charge slower?

The relationship between gauge and the total current is basic electrical physics, a wire is limited in the amount of current it can transfer therefore a larger wire can carry more current. This effect is even worse if you buy really long USB charger cables, you get a longer cable at the price of charging speed.

How do I increase USB cable length?

A simple way of extending USB is by using extension cables. USB extension cables are useful for extending devices over shorter distances and typically max out at around 3m in length. An alternative to standard ‘passive’ USB extension cables is a USB Active Extension cable.

How can I make my USB cord longer?

To use a USB extension cable, disconnect one end of your standard USB cable and connect the male end into the female end of the extension cable. Then connect the male end of the extension cable to the device that is furthest away.

Are long Chargers bad for your phone?

Unless there’s some technical flaw with your battery or charger electronics, however, using a fast charger won’t do your phone’s battery any long-term damage.
