The spiral cables used in phone chargers help reduce clutter and prevent tangling, making them more convenient to carry and store.
Coiled cables provide real flexibility of use. Thanks to their elasticity, they can stretch easily during use and then spontaneously return to their original length. This prevents excessively long cables from trailing around unnecessarily. This feature is super convenient in tight spaces, such as in a car or on a cluttered desk, as the cable always remains short enough not to be a nuisance. It is also easier to handle when you need to plug in your phone in a hurry, since you don't have to unravel three meters of cable before finding the right end.
When a charging cable is stretched or bent too often, its internal wires can quickly break. The spiral shape automatically distributes tension along the entire length of the cable, preventing pressure from concentrating in the same area with each handling. Thanks to this design, we avoid excessive twisting or compression points. The cable therefore lasts longer, as it experiences less wear with each use. In short, less twisted, less abruptly bent, your cable remains strong and reliable for much longer.
Spiral cables are easier to store than straight cables because their naturally coiled shape limits annoying knots. Instead of a tangled cable in your bag, the spiral shape allows you to stretch it as needed and quickly revert it to its original compact size when not in use. Less time wasted untangling them and fewer headaches make it convenient for everyday use. It's like a spring; it self-reverts to its shape, saving you time and preventing damage from pulling it in all directions.
The spiral shape allows for much better absorption of repeated stretching or twisting, thus preventing the internal fibers from breaking prematurely. It prevents the cable from being constantly bent in the same spot, which is often the number one reason for failures in traditional cables. As a result, your cable remains functional longer, even with heavy use, as it better withstands mechanical stress.
A spiral cable uses a simple yet highly effective design. It consists of a conductive internal material, often made of copper, surrounded by an elastic insulating sheath generally made of soft plastic or rubber. During its manufacturing, the cable is wound around a rod and then heated. This heating allows the plastic to retain the spiral shape permanently once cooled. This process, known as thermoforming, ensures flexibility and prolonged elasticity for the cable. Basically, it's like curling your hair with hot rollers: after cooling, the curls easily hold their shape for a long time. A little technical detail: this spiral format naturally allows the cable to stretch if needed and automatically return to its original compact shape. It is this elasticity combined with the ability to automatically revert to the original position (known as shape memory) that makes spiral cables practically interesting.
Did you know that spiral cables are inspired by the cords of old landline phones? This classic design has endured due to its flexibility and ability to prevent tangling.
A cable that is stretched too tightly or bent continuously can lose up to 40% of its original lifespan. The spiral design limits these mechanical stresses, thus preserving your charger for a longer time.
The interior of a regular telephone cable contains several conducting wires surrounded by a thin insulating sheath. The twisted versions have reinforced insulation that better withstands the stresses from repeated stretching.
Some spiral cables can stretch up to 4 times their original length before easily returning to their base size, significantly reducing the risk of internal damage.
No, the spiral shape does not directly influence the quality or speed of charging. However, it better protects the cable against damage from repeated strain, potentially reducing the risk of charging disruptions due to a damaged cable.
Yes. A coiled cable can indeed be used for data transfer, as long as it is designed for that purpose. Just make sure that the specifications clearly state 'data transfer' and not just 'charging'.
Use a soft cloth slightly dampened with isopropyl alcohol or a very mild soapy water. Avoid any excessive moisture and ensure it is completely dry before reconnecting it to your device.
With normal use, the spiral cable will tend to stretch slightly but will generally return to its original shape. However, excessive prolonged pulling could permanently deform the spiral and alter its practical properties.
In general, yes, because the spiral only pertains to the design of the cable. However, it is important to check the compatibility of the connectors (USB-C, Lightning, Micro-USB, etc.) before purchasing.
