  • Own this… Totally worth it for the price.

  • Any chance of the BW-S6? :)

  • If anyone is wondering, "Power3S" doesn't mean anything. Even their BW-S2 has this, and it's just a 5V power supply, no "smarts" at all.

  • most powerboards have usb sockets, no? good cable & powerboard socket is good enough?

    • Many powerboards have USB sockets. Very few of them are QC3.0 capable - they're generally very low power (5-10W) and therefore very slow.

    • most powerboards wouldnt have the quick charge component which allows charging at higher watts.
      it would default to charging slowly, which is ok if you dont mind waiting a long time.

      powerboards have usb sockets, no?

      Powerboards with USB sockets consume power 24/7/365 if you leave them connected to mains. Even though it is typically a tiny amount of power, e.g one Watt, it adds up. One Watt of power equals about $2.30 per year of electricity, and thats at QLD rates, the cheapest in the country (26.6c/kWh). After four years, the running costs of such a powerboard exceed the cost of this charger.

      Not to mention the risk of having a device with built-as-cheap-as-possible electronics always plugged in. The business next to where I work burned out a couple of years ago, the fire brigade found the fire started behind a desk, and said a power board was the most likely culprit.

      USB power boards brought into this country rarely claim any Australian safety certification. That's not to suggest this charger does, but at least you can use this charger in a way that is safer - only use it while you are awake, and turn off the power point or unplug the charger when you're not using it.

  • is this an AU plug or just some US plug with an AU adapter?

    • It's an AU plug, if you order the AU version.

      • ahhh fark i didnt see that at all and ordered whatever the default is

        • lol so i contacted their live chat and asked for au plug and they said order is still processing so wait 24 hours then contact us and we can change it.

          Except that within a few hours of that, i got an email saying "SHIPPED". So if it's already shipped then i guess the earlier person was wrong? Or alternatively they say it's shipped way before it is. Either way is not good tbh.

  • Would this be fast charging Samsung S series and Xiaomi power banks?

    My Samsung fast charger takes 2 days to fully charge a Xiaomi power bank.

  • would this work with Nintendo Switch?

  • Compared to my QC3.0 HTC Charger, this charger provides quick charge to apple devices. Nice charging brick!

  • Is this the right one to use with an iPhone for a quick charge or quicker charge?

  • Nice - at that price got a UK one for a trip to Singapore over xmas / future travel.

    Good work OP

  • I've always randomly read mixed opinions on this, but are 3rd party quickchargers(like this one) the same as using an official manufacturer one (eg.Samsung)?
    It won't ruin my battery or anything?

    I've steered away from buying these in the past for my Note9 and S10. But it would be nice not forking out $30 for an official one just for work.

      Technically, these aren't chargers, they are just power supplies, providing a fixed voltage to your phone. The part that does the actual charging is inside your phone, and that is the part that protects your battery from overcharge, decides how fast to charge, and so on.

      As long as these power supplies give out the voltage that the phone requests, and that voltage is within spec, they are as good as manufacturer-supplied chargers. I wouldn't buy an unknown-brand one though, it might incorrectly interpret your phone's quick-charge capabilities, and incorrectly supply 12V to a phone that can only handle 5V.

      • Interesting.
        Is that the same for wireless charging as well?

        • I only have knowledge about the QI standard for wireless charging, which is most wireless-charging phones but not iPhones.

          QI charging has a chip on the transmitting end (charging pad) and a chip on the receiving end (inside the phone), and they continuously communicate to keep the power at the correct level. This is because of the inexact positioning of the phone on the charging pad, and the unknown thickness of any protective case around the phone, these factors can reduce the transmitted power and that's why the power adjustment is needed.

          If a charging pad says it's QI compatible, and your phone uses QI charging, then they are compatible. However there are a few levels within the QI standard, that specify how much power can be transferred wirelessly. If you put a 10-Watt-capable phone one a 5-Watt charging pad, it will be compatible (it will charge), but at a slower rate than if you had put the same phone on a 10-Watt charging pad.

          Inside the phone, the QI chip supplies power to the phone's charger chip, but the phone's charger chip can also get its power from any charging cable that is plugged in, so you can charge either way. Some chip manufacturers may put both the battery charger and the QI receiver bits into the same chip, to save space and to reduce the overall cost.

          • @Russ: Just FYI, iPhones use Qi charging standard too.

            • @klaw81:

              iPhones use Qi charging standard too.

              Sort of. My understanding is that Apple devices won't charge at 10W on an "ordinary" QI-compatible 10W charging pad, a proprietary Apple protocol is required for 10W charging. Some charger companies have paid the "Apple tax" to be able to use the proprietary protocol, so their charging bases actually have two protocols - QI and Apple's proprietary protocol.

              That's why Apple have a compatibility list on their website. Apple is only partially QI compatible with "ordinary" QI chargers.

              • @Russ: Any examples of 10W wireless charging with Apple? From what I can see they only have the spec-compliant 7.5W charging.

                • @Clear:

                  they only have the spec-compliant 7.5W charging.

                  It isn't the QI Spec, or Apple devices would charge at 7.5W with ALL QI-1.2 compatible chargers. Even apple point out that only some QI chargers are compatible, and there are plenty that can do 7.5W and higher, but the only ones that charge at higher than 5W with Apple devices are those that Apple licensed to do so.

                  I can't recall where I read about it, but many people complained that the iPhone 7 didn't have wireless charging, at a time when it had already become standard on other brands of high-end phones. It might have been in published leaks that I saw the spec, certainly they were aiming at 10W wireless charging for the Iphone 8, as the QI-1.2 standard had listed 15W charging since 2015.

                  I recall they had difficulties with wireless charging on the iPhone 8, and it was initially released with only 5W charging. A later firmware upgrade enabled 7.5W charging, but NOT on QI-compatible chargers. Apple had announced their "AirPower" charging mat would soon be available, and the only way to get "fast" charging was with the AirPower. It was leaked that the charging mat would cost about US$200, and I'm pretty sure it was leaked that 10W was the capability.

                  Apple never got their charging mat to work, and officially cancelled its development. Since then, it looks like they have licensed out their charging protocol, hence the short list of "approved" chargers.

                  It's another case of "MFI", just like lightning charging cables. It doesn't matter how good a third-party lightning cable is, Apple devices will refuse to work with it unless the license fee is paid to Apple.

              • @Russ: I can't find a single reference to Apple devices being able to charge at 10W, or using a proprietary protocol. A little reading suggests Apple's "standard" wireless charging is 5W, and their "fast" charging rate is 7.5W maximum - all within the scope of the official Qi specification.

                Apple was planning to launch an AirPower wireless charger in 2017, capable of charging multiple devices at up to 7.5W each. This may have made use of a proprietary Qi-based protocol to correctly identify the item to be charged, but that project has been officially cancelled after they were unable to make it work correctly.

                As a point of comparison, Samsung's Fast Wireless Charging 2.0 protocol (enabled on Galaxy S10 and Note 10 devices) appears to work at up to 10W, while Xiaomi's Mi Charge Turbo is capable of 30W with compatible phones.

                • @klaw81: The only QI chargers that will charge Apple devices at 7.5W are the MFI-certified ones. An "ordinary" QI charger with 10W capability will only work at 5W with Apple devices.

                  It's even in Wikipedia: "Other phone companies that use proprietary standards for fast wireless charging include Apple, Huawei and Google." Samsung is also mentioned.


    • I don't know for sure

      But as far as third party chargers/cables go, Blitzwolf are absolutely great.

      I've never had anything of theirs fail on me

  • Do I need a special QC cable for this to quick charge? I've got some spare baseus ones that adr8 posts deals for. Thanks.
