That is normal when you want cheap china thing.

But I not agree " it's whether is real or original or not". There is no wrong if you get cheap oem cable but high resist. Because it is cheap. But not fake.

People said you pay peanut, you get monkey.

I know about wire resistance. So I don't simply get cheap thing.

Even the oem ipad cable I get is a Belkin. So I don't see any different charging time with the original cable.

when u use the original ipad charger and test with amp meter then you will see the difference.
i suspect ipad charger charges at 5.3V, slightly higher than normal

I bought a few USB Volt/Amp meter and I can say not all cables are the same.
The charging current also different depending on the model of the phone and charger.
Btw, qualcom quickcharge does work at higher voltage. Too bad my usb meter can only measure up to 9V.

I bought these 2 USB meters from Amazon :

Very useful to determine whether the tested cable is up to the task or not.

I bought a 3 meter micro USB cable from All IT for RM 27, can't even charge higher than 0.8A.
I bought a cheap extremely thick 3 meter China USB cable extender from MR. DIY for RM 9, and amazingly this thing still can charge at 1.3A after adding the regular 1 meter micro USB cable at the extender end.

You can't charge at higher voltage. If your phone require 5V, you going to burn down your phone if you input 9V.

Ampere is the different.

many factors involved here
1. charger amperage
2. cable transfer amperage level
3. cable fast charging capability
4. phone charging capacity
like my mi3, max input is 2A, when i use my own fast charging cable with fat lines only can get around 1.8Amps. (my charger size is 5A)

1. if your phone detect is normal USB cable, then is 0.5A
2. if your phone max can charge at 1A, then if you use 2A charger and 2A cable, you will end up with 1A only.
3. fast charging is just a difference with the pinout where they shorted one of the data pin, your phone will detect this difference and allow more juice than 0.5A to flow in.
4. some of fast charging cable copper core is very thin, so can support around 1A only. good cables is thick on the core, with shorted pins to enable fast charging, and braided to prevent snapping when bent

Phone that support Qualcom quickcharge can charge at much higher voltage.
However you need a charger and phone that can support the standard.

I just read in detail.

It is not charging at 9v. It depend on the phone acceptable voltage.

The charger will handshake with the phone and settle at what voltage to accept. The phone processor (snapdragon have 5/9/12V ?). If your phone accept only 5v, than it charge at 5v with higher amp. Maximum of 18w.

Guys sorry for necro this thread.

Where can I buy original usb 2.0 fast charging cable? (Remax or apa brand also okay)
