        what a crappy charger with no reviews to blow up your $1.5k+ phone?

        • JXXY1337 on 11/10/2023 - 20:27

          This charger is made by Harman - a Samsung company. The US models from what I can see have many safety certifications, don’t know for the Au models. I ordered a 20w one, can report back how it works later.

          • rumblytangara on 12/10/2023 - 20:16

            @JXXY1337: See below for comments from Catcus on the teardown to the effect that these are not well designed or well constructed at all.

    • ihfree on 10/10/2023 - 09:38

      USB 3.1 Extended Power Range (EPR) goes up to 240w.

      The only devices that I am aware of that use EPR are MBPs with up to 140W but only with the magsafe cable.

      They seem to be a Harman sub-brand - https://www.harmanaudio.com/infinity-lab/

      There are even some teardowns available.

      • rumblytangara on 10/10/2023 - 10:49

        Wow, that was such a disappointing teardown video- the guy just went through a BOM and didn't give any feedback as to how well the thing was constructed or designed. And most of us probably don't have enough electronics design information to tell at a glance what the design quality is.

        All I managed to notice was that a lot of the soldering on the back of the PCB was atrocious. Look at 4:28- really fat, sloppy solder over the top of the PCB traces (is this required for higher current? seems weird) all the soldering on the left side (again, over PCB traces) and the bottom right is a sloppy mess. Hard to tell, but it also looks like the PCB hasn't been washed properly- there's an inconsistent sheen to across the green board that looks like a grimy film.

        It's a bit hard to imagine that this is a Harmon sub-branded product, I would have expected something much neater.

        I was going to check if any more inventory had reappeared, until I skimmed that video. Thanks for posting it.

    Cactus here

    I don't think these are GanFet.

    Ill preface by saying that I haven't gone far enough down the rabbit hole into testing these because I gave up with what I did find, and it's enough for me to conclude thoughts.

    Something is very suspicious. These exhibit extremely poor efficiency. My measurements came to around 71% at load and as low as 58% on a low load (15-20%).

    Thats a power loss of 29% to 42% just burnt away as heat. You're still paying for that by the way.

    GanFet chargers usually have efficiencies of 80-85% if they're bottom of the barrel/basic/cheap/entry level stuff. They have 90-95% if they're good chargers. On average nearly all the GaNFet chargers I've tested are >90%.

    What I find suspicious is that Infinity Lab are aware of this because by their own admission in their data sheet their efficiency scores are at

    Average Active efficiency : 82.9%
    Low load efficiency: 68.5%

    Even if these are taken at face value.. These are not Gan charger efficiency numbers, these are just average silicone transistor numbers.

    Im fairly comfortable and confident in saying these aren't GaN chargers, and if they are then it still doesn't matter because all the reasons you should be using GaN aren't applicable here.

    While these have the basic protection features in place, something is seriously wrong with their circuit topology, theyre cutting corners in their with crappy parts and their design isn't making sense to me.

    These work, they're better than heymix and a lot of other brands. But if they're lying to you about this and misusing the GaN label/tech… It begs the question what else I'd find if I kept digging.

    2/5 cacti because while it's functional, you're contributing to emissions, your electricity bill, and possibly the ewaste bin in a few years if they don't hold up.

    Remember, chargers are things that should be used for several years, they don't and aren't supposed to die given they are decent. They are a long term investment.

    If you are buying a 100w or higher charger, even based off how fast devices have increased charging speed over the years, it should be something that you use for the next 4-5 years minimum because the high performing chargers aren't going to get much more better/efficient

      Which 100w GaN charger would you recommend?

    • ExpressCoffee on 10/10/2023 - 10:16

      Thanks for the detailed post. So for the 65w, is there any issue here with using this to devices like an iPhone/older 2016 macbook? I'd assume it would still be fine?

      • SmoothCactus on 10/10/2023 - 12:45
        +1

        Looking through public databases that tear down the other units, they all are built similarly with the same pool of components inside.

        I havent tested the 65w unit, I could be wrong. It might be perfectly fine.

        But based off the 100w unit which should be their flagship, and that they're using similar stuff inside, I would be lying if I didnt mention that I have some concerns for the other units

    • aaron3 on 10/10/2023 - 10:46

      @SmoothCactus can I ask if OzB is the only place you post these insights, and if not, where else? Your analyses are more detailed and objective than any others I have come across for batteries and chargers. Is this your profession in any way? It would be a dream if you had a page somewhere that would make these reviews/insights more accessible, because it would definitely be one of my top resources to help choose between these products.

      • SmoothCactus on 10/10/2023 - 12:41
        +4

        I post these just for fellow OzB folk.

        I did/do it mostly as a hobby in my spare time, I have access to a lot of chargers and banks that pass through me, some of them my own and sometimes I test them out of curiosity, particularly after noticing how much deception and lies exist in the space.

        That was a while ago and now I've gone through a lot of different stuff and have data scattered everywhere and in an unorganized manner, but a lot of things come back to me for certain units when I see them up on OzB and then I go corroborate with what I had jotted down or if I don't have much ill check with publicly available testing and then those are the posts I'll most often comment regarding.

        I guess I just don't like seeing people unknowingly get stuff that isn't whats advertised in an industry where everything is made to seem like it's great and honest and as described.. Banks especially are not.

        Especially when it comes to stuff that should be lasting people much longer than they are.

        Ill probably get around to collating and compiling everything down and posting on a site sometime next year.

    • rumblytangara on 10/10/2023 - 10:55

      While these have the basic protection features in place, something is seriously wrong with their circuit topology, theyre cutting corners in their with crappy parts and their design isn't making sense to me.

      Can you comment on the PCB? Looking at 4:28 from a link posted by @ihfree.

      PCB has some of the worst soldering I have seen for a long time, and also looks just weirdly grimy (strange filmy reflections from the green board).

      Is it normal to lay additional solder over the top of traces? I'm a total amateur at this stuff, most I've done is DIY audio kits, but the 100W amp that I put together doesn't rely on traces with an additional layer of solder slapped on top, it's just got nice thick traces.

  • SmoothCactus on 10/10/2023 - 12:30
    +4

    Glad to see Charger Lab tore it down to the component level, it saves me a lot of trouble especially on units that don't deserve much time of day.

    They do indeed use a GanFet, in particular the GS-065-011-1-L transistor, which has a peak efficiency of 92.5% if configured correctly. Obviously the circuit design leaves much to be desired on that regard because they are cutting corners where they can with garbage components in some areas.

    It seems to be a bit of a legacy design style in this. I get a feeling that they made a nice pretty enclosure and then worked backwards to make the pcb and then ended up constrained by it.

    What you observed is a symptom of a bigger underlying picture that tells a story of doing whqtever they could to save money. It's not unusual to see reinforced traces for high current paths, it's common when cheaper PCBS are used that are not multilayered and unable to transfer high currents with the original traces alone, but in high density applications it's a bit of a tell that there is a lack of optimization in trace pathing. When you are fitting everything so close together, the best thing you can do is just avoid making long paths to begin.. Which is why you will usually see minimal cases of such in most good quality chargers in the charger lab database.

    Other signs they cheaped out and rushed, an insufficient amount of solastic being used (the white goop) to dampen vibrations from components.

    No metal of any sort to act as a sink or EMI shield, you'll see many chargers with metal frames to better dissipate heat.

    The PCB just looks dirt cheap quality, even if you don't know much it's a bit apparent they cut corners there too (which is bizzare because nowadays it doesn't really savr that much money even at scale)

    • rumblytangara on 10/10/2023 - 12:45

      Thanks for that write up. I was watching the video and thinking "I am no expert, but this thing looks like a piece of shit," which you have confirmed.

      Beefing up traces with additional solder just looks so dodgy and opens the door wide to QC problems. I've opened up my share of cheap electronics off Taobao, and I still haven't come across anything as nasty looking as that board.

      If this is, as mentioned above, a Harmon sub-brand, then I shudder to think what the even less-branded options with the stupid names like OOKOO or TYMYA or whatever are churning out.

      • SmoothCactus on 10/10/2023 - 13:13

        I'm not familiar with the Audio space and only vaguely checkout headlines.

        Has Harmon gone downhill? I've heard more and more things about them that aren't so positive the last few years which is surprising because I always felt like they were regarded as industry leaders.

        • rumblytangara on 10/10/2023 - 13:17

          Oh, I wasn't implying that Harmon was a great brand so much that they are at least a recognised brand, versus the random Taobao/Ali stores that many people buy chargers from.

          I don't think Harmon has been "uphill" for possibly decades, in audionut land there is always something more serious/expensive. I've consciously avoided going too far down the audio rabbithole as it's full of crazy magical thinking. In 2017 they were bought out by Samsung.

  • SmoothCactus on 10/10/2023 - 13:02

    The popular brands are fairly good. Except heymix of course.. They've somehow entrenched themselves into the Australian market by peddling the lowest tiet garbage e-waste that I personally feel like are designed to fail. But that's a rant for another day.

    Anker, Zyron, Baseus, WOTOBE, UGREEN, etc.

    Anker made some of the first GaN chargers and they've kept up in rnd. They're a bit pricey but they are tried and true.

    Some of the best stuff are Chinese and from Aliexpress from brands that have been around longer than most of the ones you do know but sound a bit dodgy (but I promise aren't). There's a lot of bleeding edge stuff that come out that nobody knows about because it's hard to distinguish what's decent and what's not.

    One that I can pull up right now and comes to mind is WOTOBE, I've been using these two units for several years now and I like them, there are probably slightly better performing units but these are great sweet spot because the first one is good for portability and the second one is decent overall and I don't plan on getting rid of them anytime either.

    Also as a disclaimer, they have made some garbage cheap products in the past. Their car chargers suck, and they used to make some cheaper lower power units that weren't up to standard a few years ago but for the most part their product line today are fairly decent but at the same time I haven't tested everything from them but these two units specifically I have so I will share these.

    https://www.aliexpress.com/item/1005005481556527.html

    If you need something with a figure 8 that's portable the first one is great, otherwise the 2nd one is also decent.

    If you want one of the best chargers money can buy.. This is the highest density, highest output and probably most future proof thing to exist right now.

    • rumblytangara on 10/10/2023 - 13:28

      WTF they have an 800W charger listed on the table of that last link. What are people doing with these things.

      • SmoothCactus on 10/10/2023 - 17:46

        Yeah

        That is indeed 800w. They require a DC source though so it's not a typical charger.. Either you have a big power supply of sorts with this or these are hooked to batteries and I imagine most users of such are industrial applications where they are going to have devices that work off the PD spec, which is more and more common nowadays.

        I think it may have been designed for aviation, I can see how that would work.

      • SmoothCactus on 10/10/2023 - 17:42
        +2

        Absolutely none of those reviews are tests of it, teardown or close analysis.

        They have the best reviewed because they are the most purchased units.

        If you look anywhere else for reviews and reports about them, you'll find plenty of horrible stories about them, and not one off or here and there. Hundreds of incidents that occur down the line, usually after people have left a review.

        They'll work, on a surface level which is why you'll see reviews… But nobodies opening them up or testing them, and certain reviews are either deleted or drowned out. They're dangerous and it's not an IF but a matter of WHEN they will die and cause some sort of damage.

        There are hundreds of reports of units bursting, blowing, catching fire, killing electronics with it, ports stop working, electricity zapping people, etc.

        Heymix universally use bottom of the barrel components and design inside, they are a safety hazard, are hugely inefficient and cause more strain for the grid due to poor if no power factor correction, and lack basic stuff inside.

        Yup, Zyron are good ive only tested their 100w and 140w variants and I was happy with them.

        It's worth noting they engage in rebadging/rebranding stuff. Some of their units and cables are clearly generic Chinese units that have their name lasered onto the enclosure which is disappointing.

        It's expensive to make your own product lines so I understand them only having a few, but it does make it difficult to reccomend a company and say "oh anything from them will be fine"

        I bought this from Amazon and received it yesterday. It works so far, and charged my phone rapidly with the included cable.

        The box was a bit crushed and the plastic tray inside was damaged too, and the pins on the EU plug are a little bit bent, which was disappointing. I will msg them about it.

        The cable was initially hard to insert into the socket, and the travel plugs were quite hard to remove. Hopefully they'll loosen up a bit over time (but not too much!)
