I thought usb-c was the new standard These should b 24p to clear stock
Has anyone used these cables? The last time I tried a 6 foot cable to charge my phone the most I could get was 500mAh. Not the end of the world when the phone charged at twice that, but now the phones need 4 times that, it would be a massive waste of time and a bit of money!

These are supposed to be very good (read online reviews), but I personally wouldn't go for any charging cable longer than 1m (length does make a difference) - here are all the Blitzwolf items available at BG (as you may find other bits you need: banggood.com/buy…tml

Generally the reason why you get slow lower ampage charge is because you have a small gauge of wire.

Two factors: wire gauge and length. If the wire has half the cross-sectional area, it will lose twice as much power. If the wire has twice the length, it will lose twice as much power. So the longer the lead, the thicker the wire you need, which explains the comments above about wire length, but there is no theoretical reason why a long cable will not work, it just needs to be thicker. Unfortunately, the cost is in the copper, so they skimp on that and instead try to bamboozle you with pointless features such as "braided" whereas what you really want to know is the resistance of the cable, and, surprise surprise, they never seem to tell you that.
(Oh actually three factors: the cable may not even be copper, but the awful CCA.)

Depends on the insulation of the cable as well could make a bit of difference in the delivery of power. Also volt drop with the length of cable could be come a factor so let's be honest it could be a number of issues.

No, the insulation will make no measurable difference - the only possible influence it could have is in its thermal resistance, causing a rise in temperature of the cores which will increase their resistance, but as I say, this is a minuscule effect which can be ignored.
I have already mentioned the length of the cable!

Do you actually think the power will drop by half in the cable length is doubled?

The resistance of the cable will double if the cable length is doubled. For a given current, the voltage drop along the cable will be doubled. Power (which translates into how fast the battery will charge) is voltage multiplied by current. That is simple physics.
However, the device connected will have an intelligent charging mechanism which will make decisions about charging current based on the voltage it sees at its connection, so it is not possible to say exactly how it will be affected. What can be said is that when the battery is nearing full charge, it cannot be charged with full current, so the effects of the cable will be reduced.

Are you sure in real life though.

Sure about what? If you're challenging the physics, there is plenty out there you can read up on to convince yourself. And there are plenty of reports of sub-standard cables, especially long ones, not allowing fast charging.

It was a joke that we have both covered fair play you went into more detail but let's be honest most cheap cables charge poorly due to smaller gauge cable.
This actually mentions the wire gauge - bravo. There is something worth saying hidden in all the marketing BS, Of course, these cables make be fakes, with less copper inside - very easy to do.

These are half the price and are excellent quality!
No idea what the quality is, because they fail to state the most important specification: the conductor size and type. I very much doubt it's any good and the "fast charging" will be a myth.
Remember: plastic is cheap, copper is expensive. It's what's inside the cable that matters.

I am using them at the mo one for charging a nokia lumia 435, one for keeping my gopro working in my car as a dashcam without its battery , one for connecting a high power External 1tb usb 3.0 hard drive on my laptop and one for charging Huawei G300 and not had a single problem with any of the 3 cables i bought and have used em on many other items without a problem. They are also 2 metres well above the usual 1 metres which i worried may cause issues but it hasnt suprisingly - not all stuff from Hong Kong and China is poor quality!
As an electronics engineer i have also done some power tests using my variety of usb power meters like bigclivedotcom and these really are worth the money - the cable surround is very tough and well made!
Its actually the gauge that counts and if you are actually wanting to use it to push 2amps or more for fast charge or just using it to connect devices and arent anal about how fast things charge and the specs! Do you really think for a few quid they are going to be 28/24 gauge? Besides its usb-c cables that are dangerous more than the older types!
Most people wouldnt have a clue what fast charging is and most people on here just want a usb lead to connect their phone or hard drive to their laptop - why get yer nickers in a twist!
