It is true concerning computer cables cable quality has little influence on the connection speed, but to convey the two amps sometimes needed to recharge our devices, the physical characteristics of the cables are quite questioning.
There's also the quality of the connectors equipping the cable, free connection that does not fidgeting is a definite plus for many to get the load current.
Following comments from many users that pointed Anker quality cables, I have taken the plunge and ordered this set of 3 cables.
At first, the price is certainly higher than other cables on the market, so I was hesitant but already have other devices to home Anker which are of undeniable quality I have taken the plunge.
On receiving the cables are neatly packed in a simple cardboard box with a shirt describing the contents of the box, short not much to tell, I put all the selective sorting and I tested the first cable.
Visually one is reassured by their grip, no chemical smell from escaping, all is well assembled, aesthetics is successful, the cable is at least 2 times thicker than the one supplied with my original Nexus 5, it is so definitely better insulated and hopefully has a conductive core of a larger section (to check this frauderai cut both cables that I did not feel like doing at the moment), this thickness is, however, absolutely not a problem because the cable is very flexible, it does not show traces of bends and remains straight, it is also a good indicator of the quality of the copper cable (the most upscale and purest are more flexible than low-end).
I plug the charger (IQ anker 40 watt) this side nothing special, but next phone right away we feel that the connection is much firmer really click well in insertion and yours well the phone cable (we can even hang up the phone cable without fear, to not even with that of new original!) and it will disconnect properly with a good impression too.
For telephone charging speed, I can not provide reliable data, it frauderai a wattmeter to measure the electrical output during charging with the cables with respect to others, the difference for a phone application to 800mA load must not important but my camera nex requesting 1500mA I subjectively noticed that the aircraft was loading faster.
In short, excellent quality which makes it definitely very durable, many people around me have already ordered.
The 3 cables work fine for a few weeks already, by car and at home, no degradation.
