    Any ideas how many times (or to what %) this would charge a 15" M3 Macbook Air?

    Edit: Looks like it can do 1 full charge on a M1.

    • Prong on 13/05/2024 - 13:58

      15" M3 Macbook Air = 66.5Wh battery.

      After (normal) efficiency losses, the B62 outputs about 65Wh for laptop charging.

      The Macbook Air will also have efficiency losses while charging. I can't see a charging log anyone has done for it, so hard to know how many Wh it will take to charge.

      Typically you'd expect the 66.5Wh battery to take 70Wh to 75Wh to charge, depending how efficient the charging setup is. So the INIU B62 would restore somewhere between 85% to 90% capacity on the Macbook.

    I review power banks for TechRadar AU, so bought one of these in an earlier deal last month and tested it.

    I think it is amazing for $29.74 (I paid $29.99. I want my $0.25! back) but this limited deals are hard to catch. Even for $59.49 it's a good deal IMO.

    • Duckie2hh on 13/05/2024 - 15:24

      Any recommendations based on the types of power banks you have seen?

      • Prong on 13/05/2024 - 16:17

        It depends on what you need it for, as there are many options!

        These are the one I recommend out of what I have tested so far.

        https://www.techradar.com/au/news/top-portable-chargers

        I am still working on testing every power bank possible! Most of the ones in my list are also popular deals here on OzBargain.

        • Clear on 13/05/2024 - 16:24

          You should do a teardown in the reviews. To see if they're using quality battery cells and efficient IC controllers.

          • ocular on 13/05/2024 - 18:30
            +2

            @Clear: Have done a "rated capacity" test on two different INIU B63 25000mAh power banks, normally this is quoted by the manufacturer as 14000mAhr for this size power bank and is tested at a discharge output of 5V so efficiency is 70Wh/90Wh which is 77%
            I got consistently around 83% efficiency for both these units tested multiple times when new.

            Tested the OZB sought after ZMI QB826G with the same gear when new Feb 24 and consistently got 67% (didn't reach the manufacturer's stated 77%) for this discharge test.

            Tested Ugreen 25000mAh model 90597A when new and got consistently 69%

            So from my tests at least when new from an efficiency perspective INIU came out on top.

            • Clear on 13/05/2024 - 18:51

              @ocular: That's the information that should be in the review.

            • Prong on 13/05/2024 - 23:30

              @ocular: Out of interest, what's your testing setup?

              I have the 65W B63 but mine is great - over 90% of the rated capacity in most tests.

              That's likely due to the cells being slightly higher capacity than stated. I have a Baseus 65W 30,000mAh that gives over 100% of the rated capacity!

              Your ZMI capacity is lower than expected. I get about 85% of the rated capacity at 5V. But that's from the first USB-C port. Sometimes different ports use different, less efficient voltage conversion circuitry. The INIU B62 is a good example of this, as ports 2 and 3 use a 4.5A PPS enabled circuit that's noticeably less efficient than the port 1 at 5V 2A. But efficiency is quite reasonable when at full output!

              USB-A can also have more resistance and give a hit to usable capacity.

              • ocular on 14/05/2024 - 08:05

                @Prong: I use one of these and a short usb-a to usb-c lead https://www.ebay.com.au/itm/386883991526
                and discharge at 5V and restrict the load to 0.5A and wait until the power bank switches off. This takes > than 24hrs with these 90Wh power banks. Usually the rated capacity is done at much higher current, but then the resistance of connections comes into the equation. I presume the spec "rated capacity" is standardised at 5V is because for DC to DC conversion efficiency is worst when input output voltage is greatest. This shows in your testing where efficiency improves when output voltage increases. I agree it would be good to able to get access to direct output of the cells to accurately measure their capacity, but this would involve a teardown. I am a little disappointed in the ZMI output as these units are supposed to be up there with Anker. There was mention that some of the units being sold by the main supplier here in Aus were "refurbished", maybe I got one of these.

                • Prong on 14/05/2024 - 09:21

                  @ocular: Yeah nice - I will replicate your exact test and see what I get.

                  With limited time and many power banks, I only test a subset of all possible output voltages and wattages.

                  I have been doing some low wattage cut off tests (to determine the minimum wattage certain power banks without a low current mode need to stay on) but some capacity testing at those very low wattages (2.5W) would be interesting. I don't have much below 10W (5V, 2A).

                  I believe the ZMI power bank runs the 5 cells in series, so nominal voltage is 18.15V. (They give a nominal cell capacity of 3.63V). So yeah 5V will be the worst efficiency. And the voltage conversion circuits are typically less efficient at low load. I wonder in your case if there is a big drop in efficiency at very low load.

                  Interestingly the ZMI 14000mAh rated capacity is at 5V, 6A! This requires using three ports at the same time. I have recently gotten a third capacity logger (I have multiple loads already) so once I am finished checking it's accuracy, I will test the 5V, 6A capacity.

                  Also, the white ZMI USB-A to USB-C cable is quite high quality and designed for higher current. As is the USB-A port. It does PD spec over USB-A, so 20V, 5A.

                  Another helpful OzBargainer let me know the USB-A port also supports a custom PPS mode that will do 5 - 21V at 6A for a Xiaomi charge protocol. I have not tracked down the required trigger module to test that yet though.

                  • ocular on 14/05/2024 - 14:24

                    @Prong: Have Xiaomi phones and a 67W OEM charger/cable but never really got over 40W. Will try with the ZMI.
                    Was concerned about the power banks maybe cutting out prematurely with only a 2.5w, but can't detect an early cut out. I would be interested to see how your ZMI performs under a constant 2.5W load.
                    The Ugreen is supposed to have 21700 BAK cells which have a good reputation and is obviously made to look like a ZMI, it has an OEM rated capacity of 14000mAh too. I wonder if the 5V @6A is extrapolated from teardown bench tests, Is it possible for users to setup such a test with such a high current?

                    • Prong on 17/05/2024 - 08:18

                      @ocular: ZMI No.20 2.5W (5V 0.5A) test. 65.04 Wh (73.16%)

                      Anker 737 2.5W (5V 0.5A) test: 61.93Wh (71.68%)

                      Not an unexpected result, as the voltage conversion circuitry is most efficient at a specific load - often around 75% of full load. And low efficiency at very low load is normal - especially with a large change in input vs output voltage.

                      Over time I will do more tests and try and determine peak efficiency wattage.

                      And re: cut out. The power banks go to sleep unless something is using enough power to keep them awake. 2.5W is plenty to keep them awake so no cut out issues there. In my testing it's more like under 0.5W that they cut the output and sleep. This is so when a device is fully charged, the tiny bit of power it still draws when connected to the power bank doesn't keep the power bank awake, draining it. This sometimes causes issues for charging things like headphones, that may charge at under 1W. So some power banks (including the ZMI No.20 and Anker 737) have a low current mode that keeps the power bank on at very low power outputs.

                      Low current mode is also handy for hobbyist use where you might want to power a very low current device from a power bank, but not have it turn off.

                      Re: 5V 6A. I think I mentioned this in another comment, but the ZMI No.20 USB-A to C cable is rated for 6A, and can output 5V 6A with the right (Xiaomi) trigger. Which I don't have. But It can be pulled from two or three ports at once to test. Which is on my to do list!

                      • ocular on 18/05/2024 - 22:25

                        @Prong: Great comments thank you for sharing in such great detail., interesting results, almost identical to my 66wh for the ZMI @ 2.5w I now can confirm that my ZMI power bank is probably ok. It's certainly a new concept for me that DC DC conversion is less efficient at lower power, but I have no expertise in this area. I just assumed the opposite. My experience with modern cell technology comes from the world of off-grid and LiFePO4 chemistry. One concept that you can probably also apply to Li-ion is that there is an efficient relationship between discharge and recharge. So what you take you out you put back in to reach full charge. I am not sure about the charge circuitry for power banks but if you can supply 21V (5x4.2V) from completely flat to the full charge endpoint you maybe able to extrapolate this to battery capacity?
                        Also I would be keen to see what Wh you get for the INIU 25000mAh power bank. Thanks for your ongoing feedback.

          • Prong on 13/05/2024 - 22:36

            @Clear: Yeah absolutely, and it's something I'm experimenting with. But it's a big time commitment so for now the priority is expanding the number of power banks capacity tested.

            Ideally I'd love to remove the voltage conversion circuitry and test it by itself to more accurately assess efficiency. And capacity test the individual cells.

            I'm a bit power bank mad so in my own time I have been tinkering with a cycle testing setup using a spare INIU B6 I grabbed in one of the deals here. I'm very interested to log the capacity over a couple of hundred cycles.

        • souljah on 13/05/2024 - 18:53

          Got a couple of budget recommendations to check out for pairing with a meta quest 3? 10000mAh would be enough but bigger is fine. I would just be putting it in a running belt around my waist or across my back. Thin/small and doesn't get too hot would be ideal.

        • ocular on 13/05/2024 - 22:20

          @Prong
          In your figures re capacity for each power bank your listing doesn't use a consistent nominal voltage of 3.6V for Li-ion chemistry. Sometimes 3.7v is used. Is there a reason for that?

          • Prong on 13/05/2024 - 23:12

            @ocular: In short, it's because lithium ion batteries don't have a consistent nominal voltage..

            In this case the listed Wh and mAh are from the manufacturers specification.

            The nominal cell voltage depends on how the cell manufacturer rates the cell. And what actual charge and discharge voltage cut offs are used by the BMS.

            Typically the nominal voltage is the half capacity point at a 0.5C load. Different cell chemistry will have different voltage characteristics and thus nominal voltage.

            No doubt some manufacturers are overstating the nominal voltage, or not actually charging to the required voltage to get the rated capacity! A few power banks (that I don't recommend) even claim 3.85V nominal voltage. I doubt they use the required cell chemistry and charge voltages to achieve that.

            It's not an issue for the testing results and reviews, as I give actually real world tested Wh. If manufacturers inflate their Wh ratings using higher nominal voltages that aren't actually correct, then it actually makes the results for them worse, as the real world capacity is a smaller percentage of the inflated capacity, giving worse efficiency.

          • Prong on 15/05/2024 - 05:58

            @Duckie2hh: The INIU B6 is a great option.
