No code needed.

    Anyone tried these from the last Amazon deal - are they any good ?

    • +10 votes

      I got 2 white ones, I charged my Xiaomi 2C 20000 mAh, the chargers both got extremely hot, one of them charged the powerbak half way and decided to stop and refused to continue charging when I tried again few times. the second was happy to continue finishing what his mate had done, but again this got so hot. I have sent them back to the seller for refund.

      I returned and they refunded me for the items only, not for postage, so I should have thrown the chargers in the bin to save time :) good lesson for me to not shop the weird brand name again.

    Yeah bought these in the last deal and they are amazing and fast charging like they claim.

    It was $12.74 multiple times last week, and the week before.
    It might be better to wait until they drop the price again.

    What cables do you use to get the fast charge?

    •  

      Any decent/branded micro USB/USB-C cable would suffice. Only really cheap and thin micro USB cables usually have problems.

      •  

        Can you recommend any from Amazon or good deals recently that can support QC3 Micro USB and/or USB C

        •  

          If yon don't mind just QC2, you could consider Samsung fast charging kit (with either Micro USB or USB C cable) - $20.30:

          https://www.jbhifi.com.au/samsung/samsung-fast-charging-trav...

          The catches are: 1. The USB-A plug is on the side (so you need to use it on the right most power socket). 2. It does not have the Apple 5V/2.4A coding so it won't charge iPad quick enough. Basically, not for Apple devices.

          •  

            @netsurfer: I think its very hard to tell buying cables off eBay so I guess retailer and proper Samsung product for sure will work

            • +1 vote

              @neonlight: Even reviews for third party cables are unsafe. Blitzwolf cables were good, but some people mentioned the quality has dropped in the latest batches (unconfirmed). j5Create and Anker cables are also batch dependent with some batches got rave reviews from proper testing, but other batches failed badly.

              Honestly, I should probably get a Samsung pack and run it through my USB meter and check before recommending them. I haven't checked the included cable, but did find the charger lacks Apple coding (likewise, Apple chargers are not coded to work well with Android). Cheap chargers are more likely to have more codes (i.e. will work with Apple and Android - though voltage and current noise would be higher).

              •  

                @netsurfer: That makes things even more complicated. I would have thought most Micro USB cables should be 2.4A compatible for now after so long, but I guess there are still many generic micro USB cables out there… With USB-C when it was released I thought QC3 was already introduced so they should be ok? I believe Samsung kit was for QC2 only unless there's a new revision for QC3. However $20 for a cable is fairly expensive. Not sure what to do atm.For a geniune working QC3/QC2 cable is more expensive than this deal itself!

                  @neonlight: Not all microUSB cables are 2.4A capable (most cheap ones aren't). It comes down to cost and 2.4A is probably only needed for tablets. 2.1A is acceptable for phones. Even some original microUSB cables for phones are only 2.1A capable (or worse for cheap Android phones). For branded cables, you will find most makers would charge a premium for 2.4A cables (so you might want to settle for 2.1A).

                  QC2/QC3 on USB-C is not USB-IF endorsed standard. Both Google and Apple picked USB-C/PD. QC4 is USB-PD compatible. It's not worthwhile investing in QC2/QC3 chargers unless you intend to still buy midrange phones in the next few years.

                  Can't you stick with original cable(s)? It doesn't have to be a cable from a phone that supports QC2/3. For example: if you have old Google Nexus phones, the micro USB cables provided would be good quality ones and work fine for QC2/3. If you really must go for cheap cables, perhaps just make sure the cable states it is 2.1A/2.4A and try your luck.

                    @netsurfer: Yeah I get ya. The thing is sometimes you want extra QC cable on the get go, eg. in the Car or with a spare charger. But you don't want to buy official kit

    •  

      If micro USB, if you must use non-original, try to get 2.4A ones. If USB-C, try to get quality ones or original ones (e.g. Apple, Samsung or Google).

      Micro USB - unless you have a meter, you don't actually know how fast it is charging. My brother bought a cable from Diaso and he thought it was fast charging. However, when he used one of my cables, he noticed a big speed difference and when we measured the current through a meter, there was a 35%+ difference. The cable I let him try has a built in meter and can support >2.4A.

      USB-C - even USB-IF certified cables are unsafe. Amazon Basics (being USB-IF certified) consistently charges at lower voltage and current compared to Google or Apple originals. Furthermore, the one I have has occasional tendency not to engage USB-PD fast charge (stuck on 5V). It was only because I have a USB-C meter so I can tell. That Amazon cable is now collecting dust.

      I stick with original cables if possible (more consistent, better quality). It's just not worth the fuss to carry a USB meter to check whether the cable is working properly or not.

    Would it work with Huawei Mate10 pro/P20 Pro?

    • +2 votes

      It would work but for fast charging you need a Huawei SuperCharger.

    • +2 votes

      Based on the specs, it does not support Huawei's fast charging standard. Unclear which charging mode it will fallback to.

      Recently did a test with original chargers and original cables (through a USB-A/USB-C meter). Original chargers are good, but they only offer support for their own devices. For example, Apple 12W charger will charge iPad at full 12W, but for some Android tablet, it won't even allow more then 1A (5W). Similarly, a Samsung fast charger, despite indicating 2A @ 5V, won't feed full 2A to iPad (as it is not coded to do Apple 2A/2.4A standard). Voltage stability and noise level are generally much better with originals (and they use better quality parts inside).

      Then, you have different grades of cables (e.g. micro USB: <1A, 1A, 2.1A, 2.4A).

    Ordered these when deal dropped last. One of the two was DOA but the one that does work works well.

  •  

    Would like 5 usb socket in one unit.

  •  

    Same price without Prime.

  •  

    Would these work with a Google Pixel 2

  •  

    Does this come with any cable?

    I bought these on the last deal. I don't recommend them. They claim up to 3 amps at 5v yet at only 1.5 amps the voltage has already fallen to the minimum allowed of 4.75v, so I doubt it could maintain 4.75v at 2 amps let alone 3 amps. The charging current at these lower voltages drops considerably so your charging time will increase significantly compared to a charger that can maintain 5v or even a little higher. I guess that's what you get for around $6-7 each.

    I'm no expert, just my 2c worth.

    Got one of these with a second-hand phone and as others have said, the voltage sags a fair bit (4.73V as per my cheapie USB "multimeter") and get ridiculously hot. Started charging intermittently after about an hour - straight into the bin. Not worth having a potentially dangerous charger to save a few $. Reviews also have a bit of a "paid" vibe to them.

    This is a dangerous product, i ordered two from the previous deal. Get extremely hot when charging, one stopped working now after charging a power bank half way. This product should not be allowed. I asked for a refund already.

    •  

      Unfortunately have to agree. One was dead - didn't work. The other got hot within minutes. Not worth the risk of connecting expensive devices to these cheap plugs. Also asked to return them and they refunded me.

    WARNING
    An update - I just received 2 of these today, and as soon as I plugged one into the socket, there was a bang, and sparks/flame shot out of the USB slot, feeling the pressure of it on my palm as I was holding the adapter.
    (no burn luckily)
