WELCOME10

PortaPow is basically the god-cable of increasing your charging speeds for Non-Quickcharge 2.0/3.0 devices. If your device is on this list, don't bother. Otherwise, this cable is for you! (https://www.qualcomm.com/documents/quick-charge-device-list)

The cables normally cost $11+ on ebay (http://www.ebay.com.au/sch/i.html?_odkw=portapow&_osacat=0&_…) each, and i've been looking at these cables for months.

Why you need this cable: http://goughlui.com/2014/10/01/usb-cable-resistance-why-your…

To get the 10% off, just wait around the store and it'll have a popup asking to email it to you.

$7 flat postage

It also has a few adapters that change regular cables to charge only cables by blocking the data lines. For android, there are actually THREE ways to wire your micro-usb cable, and wiring it the wrong way internally impacts charging speed. These adapters figure out which way to "rewire" your cable internally:

  Am I missing something? No lightning cables there that I can see.

    There's a lightning data-only adapter.

    Sorry, i wanted to post the fact that there are charging adapters (apple + microusb) and cables (microusb only) but there wasn't a way to succinctly write it. Hence why i didn't write "cables" in the title.

  doesnt the device itself also limit the charging speed

  also are u saying these cables and adapters will provideno benefit to QC devices?

    Will provide no benefit to QC2.0 and QC3.0 i believe.

    The device limits the charging speed, but if you have a QC1.0 device and a shitty cable, the qc1.0 device won't pull the full 2 amps.

    The easiest way to check is do download the ampere app. Then check if your charging rate is at least 1000-1500mAh. If it is something like <400-500mAh, you probably need a better cable.

      ah right

      that rewiring adapter is pretty interesting

      a bit technical for me, but how does shorting the data lines increase charging speed? is it just using the data lines as charging lines?

        Sorry for late response,
        but basically there are three standards for USB Charging

        1) Short data lines identifies the cable as a charging cable
        2) Data lines have a 28ohm resistor identifies the cable as a charging cable
        3) Data lines intact

        If a phone detects a cable as "data" it will only charge at 500ma.

        If it detects as charging cable it will try to charge as fast as possible.

        @aong152: is there a difference functionally between one and two?

        isnt the usb standard to support 5v 1A and higher Amps or "as fast as possible" isnt officially supported?
        I suppose with QC, any risks of overvoltage/high current is managed by the hardware supporting it right

        aong152 on 07/12/2016 - 16:08

        @furythree:
        Probably no difference between 1 and 2.

        The "official usb-if" standard is as you said, 5v 1A and higher amps not supported.

        Samsung/China/Apple made their own standards on top.

        Samsung -> Data lines intact, sends a data signal to charger to negotiate charge speed
        China -> Short data lines = max charge speed
        Apple -> Data lines intact

  Needed a good excuse for some more cables. Have a collection of rubbish ones (thin, cracked, lightweight)
  Plus some other goodies that excite me slightly too much!
  Cheers OP!
