It is not the first time we talk about whether a longer cable It can affect the performance of an iPhone or Mac, taking more or less to complete a load, however, 2 or 3 meters cables have always been commented, never something as exaggerated as today.
However, on certain occasions, especially in houses with a pool, or garden, where we do not have a plug close, there is the possibility of using very long cables to have energy anywhere, however, is it viable? Does it have contraindications? Let's see it.
What is the length limit of a load cable
Although there is no real and fixed limit for a charger, we can see what problems we would have if the cable is longer, being able to finally analyze whether it would be viable to have one of 20 meters, or not.
- Energy loss: The longer the cable, the greater the electrical resistance, which can reduce the efficiency of the load. If the cable is very long (for example, more than 3 meters), you could experience a slower load. Hence it is weird to see them.
- Apple specifications: Apple does not specify a length limit for load cables, but Apple's official cables are usually 1 meter and 2 meters. However, longer cables, such as 3 meters or more, they are also available in the market, generally manufactured by third parties, so it takes us to this question.
- Cable quality: Low quality length cables may suffer more signal and energy losses, which would affect load speed. Be sure to use certified cables (for example, Apple MFI cables) to guarantee good performance. However, from 3 meters, it is more complicated to find them.
What to do if we want to use 20 meters cable?
In this case, there is an alternative that we all know, and that would be the most practice. Use an extender. There are this type of cables, using very commonly in the works and constructions, which can quietly exceed 20 meters, and that are prepared not to suffer loss of speed, so it would be like having a plug closer to the desired place.
By using such an extender, we could connect our charger of 1, 2 or 3 meters, in a more comfortable way and without dangers, because getting a real light or USB-C cable of these dimensions, could bring many voltage and electrical resistance problems, as we commented, getting a Slow and dangerous performance for our batteries.
In summary, No, you can't use a 20 -meter cable, but there are alternatives such as plug -in elongators that they would work correctly and fulfill the same mission, although, for security and to guarantee that performance, they are more fat and heavy.
And you, what is the longest cable you have bought? Have you had any more than 3 meters? Leave us a comment with your opinion and experience in this regard, since we may not be many who need this type of “inventions”, but any help is welcome to the few who do seek it.
