      apparently this: https://www.ozbargain.com.au/node/708690
      but the reviews for the brand seem consistently fine on Amazon - so its a case of a battered reputation by Ozbargain community
      Before all this - I bought a few of their chargers like this https://amzn.asia/d/9yhYLaF and they're still going fine. So I guess maybe their quality control failed a few times. But overall the reviews on Amazon seem decent. Happy to be corrected.

      • SmoothCactus on 22/04/2024 - 18:12

        Or there is a reason why Amazon reviews are that way that is due to the nature of the systems in place?

        People universally never go back to rewrite review issues on Amazon should they arise, and Amazons return/refund policy makes it so that its easy to get an issue sorted and get a refund, in such a case unless you are vindictive why would you go back to rewrite a review if you even remember writing one?

        Additionally, most reviews from general consumers and amazon users are done shortly after receiving products. and that is usually fine, but it means that some degree of skewing occurs in products that have particular failure modes that require usage and time.

        Theres also lesser factors like how there are a greater number of reviews from people that may not recognize issues with banks because the vast majority of the population cant even recognize the symptoms and signs of battery degradations until its too late, as batteries can show 100% charge but that doesn't mean they're holding 100% of the charge you had on day one (See discharge and degradation explanations, eg phones with damaged batteries that charge to 100% but they drain that very very quickly). Other factors like companies encouraging reviews or outright providing compensation for them, review botting, etc.

        OzB is a discussion forum where people talk in greater depth and often go into why something is the way it is, discussions are not final in the same way a review is, this simply isnt information that can circulate and exist through the review system on Amazon, even review youtubers will frequently go back and make edits, changes or re-review things.

        I can go on about systemic differences, but HeyMix has a track record of systemic and long term failures for a good reason, its not without evidence, data, internal analysis and reports to back it up, nearly every HeyMix product ive opened up including this one has had problematic garbage inside that is safe, only until it isnt, or batteries and circuitry inside that looks like a good deal, until it isnt. But its easier to just move on and buy a new one when it happens rather than go back to let everyone know.

        People posting these deals don't know better because OzB doesnt allow great continuity of discussions and things are buried, so people hear things in the wind but dont know why or to what degree, there are going to be people asking the same questions on this post as there will be the next, even someone explaining why will never be able to pass along the trove of data that exists in a single comment, but frankly if you did see everything posted in the past 12 months, you might be regretful in posting this as I know many people I have spoken to here have been, because many including myself have had thousand dollar devices destroyed, had units explode and had fires nearly start.

        Im not saying this is going to be or will be everyones experience, but even 1 in 1000 is too great a risk for the devices you will plug them into - especially just to save less than $0-$25 over what should be several years.

        • roller on 22/04/2024 - 21:06

          The simpler explanation is the power bank burned their house down and the have nothing left to access Amazon with to leave a review ;)

      • Aureus on 22/04/2024 - 18:34

    The Heymix 100W is not great. I bought and tested one in a previous deal. At 100W, you get about 73% of the rated capacity, which is well below average result. Likely the cells are poor quality and probably won't last too long. More testing info - https://www.ozbargain.com.au/comment/14520365/redir

    The Anker power bank linked in this deal is a very old model and it's ridiculous Anker keeps selling them here. Only 5V output, and microUSB charging! Avoid it.

    The INIU power bank linked (B41) is 5V only, so no fast charging. The INIU B6 is the same price and a much better deal as it is a great power bank.

    https://www.amazon.com.au/INIU-Portable-Charger-10500mAh-Cha…

    The Veektomx VT103 linked (the last power bank in the deal) is not a great power bank, but not as bad as it used to be. It is a bit smaller than most, but also gives less than its rated capacity. The INIU B6 is a few dollars more (and slightly larger) but a much better power bank.

    More VT103 testing info. https://www.ozbargain.com.au/comment/15187432/redir

    • foreverphoenix on 22/04/2024 - 17:10

      Awesome post - I guess you get what you pay for; generally the pricier chargers give you more juice
      But the cheap batteries have been okay for daily use for me given their price for now. I need to invest in a good one for camping however

        The main concern for me with most of the cheap power banks would be longevity. The poor quality cells being pushed beyond what they are rated for will tend to wear very fast, and fail early.

        On the cheap end of the scale, INIU seems great. For the models I have tested, they actually use cells that can handle the discharge wattage and give the rated capacity. INIU have a 3 year warranty and comments here seem to suggest support is good in the event of a problem.

    Trolls should grow up.
    A couple of heymix faults and EVERY product they have gets the same inane comments, it's got too old to be "funny".

    I've got heymix. No fire, no heat and they work as expected.

    If any brand has a fault or two should we reject every product they make forever?

    If that's true then OzB should ban Samsung, F&P, duracell, LG and I could go on. A supposed premium brand I own has had multiple faults and recalls. A recent one was for electrical fire. Festool Kapex mitre saw. It's close to $2K. But people still buy them in droves. I've given up the brand.

    • Prong on 22/04/2024 - 17:47

      Heymix puts their brand on products made by a large range of OEMs. Which is not inherently a problem, and many brands do this.

      But Heymix has shown they don't put a lot of effort into checking the products are suitable quality. Some of the products are perfectly good. Others are terrible.

      The Heymix power bank in question is one of the poorer quality products, and does not meet the capacity specifications. The cells used are likely not well suited to 100W discharge, and will wear fast / fail early.

      This lack of quality control is a good reason to avoid the Heymix brand overall.

    • netsurfer on 22/04/2024 - 18:25

      The main issue is some of their products have serious safety issues. From what customer posted (showing the inside of the products), they are very concerning. A big issue is that with all these USB-C and Quick Charge accessories, the chipset comes with some of the safety features. However, the main difference between branded ones is they will implement safety features on the circuits and not cheap on and hope the chipset will cut off (or worse blow up some components when there is an issue).

      Sure, Samsung and even Apple have started using more cost effective components on their lower end chargers, but they still follow safety standards. Even Anker, in quite a few teardowns I see, you can tell it does cheap out on certain design (and I'd rather see proper safety circuit design, instead of extra insulation tapes inside).

    • SmoothCactus on 22/04/2024 - 18:30

      If you think its a fault or two, you simply dont know better.

      Lets say it was a 1 in 1000 chance, which I believe is likely a fair number given the volume of chargers in circulation and what testing/tracking ive done over the past 9 months, would you take that risk with the cost of the devices you're plugging chargers into every single time?

      How many people have to post detailed breakdowns of circuit topology, poor quality components, QC issues, exploded units, not following national and international standards, etc etc.

      These things dont fail on a basis of how much you use them so much as they do spontaneously and abruptly, you may be fine today but to use that as a basis to say its fine universally is silly with how much info exists out there. Its no different to saying its fine to drive a poorly designed and faulty car because you and plenty of other people havent or have yet to run into any issues.

      So basically no data and lots of hysteria. and speculation of a few faults.

      Hey I don't care what you buy, but I'm rather tired of stereotyping and cheap shots.

      • Prong on 23/04/2024 - 00:08

        I tested the power bank. It provides 73% of the rated capacity, and can't sustain the rated output.

        It's not a good power bank.

      • bbbounce on 23/04/2024 - 02:28

        Half the sellers are international companies selling from pre-customs warehouses located on Australian soil. You can buy something and have it delivered the next day, but under our stupid customs laws, it's technically sold from overseas, and each buyer is legally the importer and responsible for making sure the product is safe and complies with local laws.

        The Gov has shown no interest in creating regulations that mean marketplaces like Amazon, eBay, Aliexpress stop this practice. And now they get their 10% GST, why would they?

      Isn't it easier to write 20 Ah instead of 20000 mAh?

      That’ll only add to the already confusing and incorrect use of mAh for denoting battery capacity. Its about time manufacturers started using Whr which is the proper unit for measuring battery capacity, instead of the half ass mAh that means nothing without a voltage; especially with these higher capacity high output battery packs that are capable of charging notebooks which don’t use a mAh rating with their batteries at all. I guess these people only want a higher number for marketing..

    • netsurfer on 22/04/2024 - 18:34

      mAh allows you to work out roughly how many times you can charge a mobile device (since the battery of a mobile device is also quoted in mAh).

      Also, this device can't send out 20A constant for 1 hour. If it does that, it will certainly be a huge safety risk.

      • opt on 22/04/2024 - 22:11

        mAh allows you to work out roughly how many times you can charge a mobile device

        Only for mobile phones and other small devices (like watches) that use batteries with a voltage of around 3.8v. For larger more powerful mobile devices like tablets and laptops that use higher voltage batteries the mAh value cannot be directly translated. For example, my Lenovo Duet tablet has a 7.72v 5470mAh battery and my notebook a 11.4v 4913mAh battery. To calculate how many times those devices can be charged I need to consider Whr rating (mAh x v /1000), which is why mAh by itself doesn’t make any sense without a voltage, which BTW this manufacturer has not even listed.

  • Prong on 23/04/2024 - 15:56

    Anyone who bought this, can you request an invoice from the seller?

    When I bought one to test 6 months ago, the seller was a Hong Kong company.

    I am curious if that is still the same now.
