  Will it work with iPhone 8 for fast charging?

  It says:
  “Compatible with iPhone 8 iPhone 8 Plus and iPhone X wireless charging at up to 5W”

  5w will just be normal charge speed won’t it?

      Yeh thanks for that - read this article which explained it all pretty well. Seems like it’s charge slow or submit to apple at the moment

    Iphone 8 quick charging is done over USB PD and requires a 30w USB C charger and lightning to USB C cable.
    See here for more detail: https://ios.gadgethacks.com/news/why-iphone-x-needs-25-usb-t…

    When talking about Apple products fast charging refers to 2.4a and quick charging usb C. Quick charging for android gernerally refers to Qualcomm quick charge standards.

      I have a couple of blitz wolf lightning cables from previous deals - they support 2.4amps. Any reccomendation for an 12w wall unit to bump up the charge speed a bit compared to what’s in the ip8 box?

        This is the one you want:
        https://www.aliexpress.com/item/Anker-USB-Type-C-with-Power-…
        https://www.amazon.com/Anker-Delivery-Charger-PowerPort-Sams…

        Reputable brand, reasonable price only doesn't have AU plug type that I can find so far. There will be a lot more USB PD products out in future thanks to the iphone however this would probably be your best option at this stage.

        Or were you looking for a non quick charge option as pretty much any 2.4 charger will supply that?

        Here's a blitzwolf one: https://www.banggood.com/BlitzWolf-BW-S9-18W-USB-Charger-EU-…

      I like how they don't provide you the quick charger or the cable. If you buy the apple brand it will set you back a lot. If you buy third party, they can disable the accessory at any time. That's what they did to my perfectly working charger when I upgraded to iOS 10.3. It said "this accessory may not be supported" and refused to charge.

      Quick charging for android gernerally refers to Qualcomm quick charge standards.

      It depends. Some, like Google products use USB-PD. Benson does not endorse any Qualcomm standard that uses USB C and recommends not buying those products.

        I think when apple products do that including third party it's not that apple has disabled them it is just that it has developed a fault somewhere that means it fails to recognise the protocol or some other issue.

        That's why I said "Quick charging for android gernerally refers to Qualcomm quick charge standards" because it is the most common, of course there are others out there such as dash or turbo charging. There are lots of Qualcomm quick charge mobiles on the market right now Samsung and LG among them. The point was to clear up what the terms mean in reference to Apple products mostly.

        @UponOccasion:

        I'm using the official charger, but 3rd party cable. The cable is new (used it for a few weeks only) and worked fine until it magically developed faults the moment my iPhone got updated to 10.3.2 which I don't recall ever authorizing. I even used an ad blocking VPN to block the site that checks for updates, and it still updated without me knowing it.

        This is a commonly reported problem on apple forums that began with 10.3.2.

    I don't think ip8 supports wireless fast charge

    •

      ip8 do not support Qi FC (which use 9V)
      however, ip8 can charge at 7.5W rate

      For standard Qi wireless charging (including this one)
      ip8 will still charge at 5W
      which is slightly slower than the 7.5W rate

  I purchased this from AliExpress last month, and received it recently. Doesn't charge as fast as cable and my Samsung S7 heats up quite a bit.

  • 

    Eggsperential on 26/09/2017 - 01:52

    Yeah my s8 heats up a fair bit, to the poinf where i'm starting to worry about longevity of the battery. It is a fair bit slower than a cable to charge but this is to be expected i guess.

      I've been Qi charging my Nexus 5 every day from day 1 and it's been fine, battery still works great.

        Eggsperential on 17/10/2017 - 00:19

        Are you using the blitzwolf charger? My friend has a samsung qi and her s8 doesnt heat up so guessing its the blitzwolf. Ive got 2 s8s and 2 blitzwolf and they both have the same problem.

        @Dc2itr:

        No I am just using a non branded one I got of ebay, but it's been great.

        I actually have it at my computer desk and I put my phone on it whenever I am at the desk so the phone is always being kept topped up. I don't use it like a regular charger where most people drain their battery during the day then plug in at night to charge up.
        I also have a wireless charging phone holder for the car.

        Wireless charging will generate more heat than regular charging. It can either charge slower and generate the same heat, or charge quickly and generate more heat. My charging pad is slow, but I don't mind because I'm not charging a depleted battery.

        I'm not worried about the heat/battery life though. I have a 2.5 year old Nexus 5 with original battery still good. My old Nexus 4 is 4.5 years old was Qi charged daily and is still running on the original battery.

    Use the Samsung Adaptive Fast charger unit to plug the USB cable into.

    My s8+ and Note8 actually change to show fast wireless charging when you use the plug and not a standard USB port.

    Qi is never going to be as quick as a cable.

      ome research into Apple's current lightning charger revealed that the small 5W charger is just about 78% efficient. Qi (the tech Apple uses) hovers at around 59.4% efficiency, based on their own studies. This difference may seem fairly small, but in fact is a huge sustainability failure. What an 18% difference in efficiency means is that just 60% of the power spent actually makes it to the battery, leaving 40% dumped as lost waste heat. Compared to the wall charger, which only wastes 22%. Modern computer power supplies can achieve 80-90% efficiencies, which is even better.
      When you consider that there are roughly 1 billion active Apple phone users worldwide, constantly in need of a charge, the situation starts to become more clear.
      The Math Part
      Let's assume everyone has brand new iPhone 7's, since they are familiar to me. I need to charge my phone every other day, which seems to be above average performance compared to my friends. The battery in the iPhone 7 is 1960mAh, or 1.96Ah producing 7.04 watt-hours of output. Including the losses from a wall charger, charging a phone from 0% will take 9.03 watt-hours from the grid to charge it, while the wireless charging system make it take 11.8 watt-hours. This results in a difference of 2.77 watt-hours total, or 1.36 wH as I charge my phone halfway each day.
      Now we convert that to kWh, resulting in .00136 kWh per phone, per day. And multiply that by one billion people, resulting in… 1,360,000 kWh that we are now dumping into the atmosphere as waste heat every day, just so we can avoid plugging in our phones. And that is 1.36 MW of power that needs to be generated, every day, for us to have this neat feature on our phones. That's roughly $64,500,000 USD worth of power, every year, being used up because we chose to charge our phones using an inferior method of charging.
      I've heard a few arguments about improving wireless charging, that the efficiencies can be pushed to 70% or above. The problem is, that will require far better precision (and cost) than is practical, and meanwhile we could have made better wired chargers that are above 85-90% efficiency. So the gap stays about the same when we push both technologies to their limits, and thus the cost overhead.
      Wireless charging is not a very sustainable practice, unless you somehow compensate for the poor efficiency by making material savings, better longevity, etc.
      TL;DR: Wireless charging is bad for the environment. There are so many phones that a small change in efficiency makes a significant impact to world energy grid usage.
