      If price is similar I'd go with charmast for form factor. These go down to $10 ish from time to time if you're in no rush

      The INIU B6 in this deal is a much much better quality power bank. It's the best affordable 10,000 mAh available.

      The Charmast ‎W1150L has a fake capacity listing and is 7,500 mAh not 10,000 mAh. The cell quality is also not very good, and it does not handle 20W fast charging well. IMO it's not worth buying at all.

          I test power banks for TechRadar Australia.

          This is my personal account, but OzBargain rules mean I can't link to my reviews or buyers guide in the comments of deals I did not post.

          But my profile has a link. Or google "best power banks in Australia" or similar, and my TechRadar buyers guide should be at or near the top.

              @witsa: Yep, because while I have tested a lot of Charmast power banks, none of them have been any good.

              I'm currently working on an updated format for the buyers guide that will include a list of all power banks and the ones not to buy.

              Charmast is best avoided. The same goes for other Amazon brands like Veektomx and Imuto. There's one VRURC power bank I really like but many of the other models aren't as good.

        The Charmast ‎W1150L has a fake capacity listing and is 7,500 mAh not 10,000 mAh. The cell quality is also not very good, and it does not handle 20W fast charging well. IMO it's not worth buying at all.

        Genuine question here: What sort of technical testing do you do that shows cell quality? I'm guessing you don't have the time to cycle individual samples through a couple hundred full discharge/charge cycles, so what other ways are there to determine cell quality? Being a total noob at this, I would guess at something like doing a load of discharge/charge cycles then trying to measure internal resistance.

        What gets me on things like those Charmast deals is that the packs are visibly smaller than other 10,000mAh powerbanks, but people somehow take at face value that the number is accurate. With cheapo products, there is no magic sauce or alchemy that can violate the laws of chemistry and vastly increase energy density… radically smaller form factor clearly strongly suggest that something else is being lost along the way.

        • Prong on 17/09/2024 - 14:27
          +2

          So my use of “low quality” here is being used to describe a bunch of factors that are not necessarily technically quality issues. And yeah, while I have experimented with cyclic testing, I don’t bother for power banks that don’t even meet their rated spec.

          In this case, running capacity tests at a specific voltage, but varying amperage, gives an idea of how the Charmast cells handle load. I don’t bother pulling the cells out, so there is a margin of error due to varying efficiency of the voltage conversion circuit at different loads. (generally this is minimal at 5V)

          The rated cell capacity is at a specific (unknown) discharge rating, and a higher discharge rate will result in less usable capacity, while a lower discharge rate results in a higher usable capacity. A power bank with cells that are suitable for the rated output won’t have the tested capacity vary very much from high discharge rate compared to low discharge rate. And of course will output a capacity that matches the rated capacity after typical efficiency losses.

          Power banks like the Charmast mini (and any of these extra small models) tend to give very big variations in tested capacity at high vs low load. With this level of testing I can’t say if it’s just that they are using good quality cells that are not rated for the discharge rate, or the cells themselves are poor quality and not rated for the discharge rate.

          There are cells available that are both high quality, and have the required energy density to meet the rated spec in the size available. For example they may be built to handle higher charge voltages (and lower discharge voltages), giving higher usable capacity for a given size cell. Many mobile phones use such cells because the extra cost is worth it – but it’s no surprise that cheap power banks are not using fancy cells.

          By comparing the (logged) output capacity, vs the Wh it takes to charge the power bank, I can get a rough idea of the actual cell capacity. Most of these mini power banks are around 7,500 mAh, though some might be slightly higher, but just not rated for 20W. I also compare to some of the bare cells available from china, and the dimensions fit for various cheap 7,500 mAh cells that are often rated at just 0.2C – so shouldn’t be outputting more than about 5 watts. There may be some cells that are technically rated for 10,000 mAh at very very low discharge rates. Either way, they are not suitable for use in the power bank, and will have highly reduced cycle life.

          There are a few other factors I take into consideration. Failure rate is one – cheap cells often self drain very quickly, and/or develop internal shorts. I also leave all my crappy power banks fully charged, and for some I do an occasional capacity test to see how much the cell capacity is degrading over time. Some have dropped 20+% in a year. Some will drop in capacity just over the 10 or so cycles when testing a range of voltages and amperages!

          For “good quality” power banks like the INIU B6, I carry one with me and will often use it to top up anything that needs charging, just to build up the cycle life in somewhat normal use. And then capacity test it every now and then. I do also buy the B6 whenever it is extra cheap and give it as a gift to friends and family. Then every so oftenIi swap theirs with a new or different one, and do a capacity test. I have not had any failures, or signs of more than minimal capacity loss from wear. I did experiment with automatically cycling a B6, but the wear was slow (and as normal), so I didn't bother continuing, as it was more effort than it was worth due typing up one load tester. (As far as I am aware, INIU is a brand direct from the factory that makes loads of power banks for Anker, Ugreen etc, so no surprise their quality is good)

          • rumblytangara on 17/09/2024 - 15:11

            @Prong: Thanks for that. I appreciate your efforts in totally geeking out over this subject, especially with the longer term testing of the units given to other people.

              @rumblytangara: I always love an excuse to talk about this stuff!

              And yeah refining the testing methodology is one of my favourite bits. It's a big trade off between how long things take, versus how useful the info is. As much as I want to do tear downs and cell / circuit level testing, it's a bit too time consuming. I'd do it in my own time just out of interest, but I have a backlog of more pressing projects for now :P

              I did have a thought about a fun way to do daily cycling. I have an old solar panel sitting around (already laying on my flat garage roof, with a wire running in from a previous experiment), and a little voltage step down unit. I should have a 5V relay somewhere (or grab one online for a few bucks). I can charge the power bank during the day, and have the relay set so when the sun goes down and the charge stops, it connects a load. The solar panel is an old 100W one, so even on a cloudy day it will still produce enough power to charge the power bank.

              The load will need to be 3W+ to make sure a 10,000 mAh power bank discharges overnight. I am pretty sure I have a 5W 12V LED spare, and a power bank like the B6 does 12V from the USB-A ports (using a trigger, which I have).

              Sure, I will have made a solar light with extra steps… But it will cycle a power bank daily, which is a reasonable approximation of heavy use. And I have a spare B6 from this deal. And it seems more fun to use the sun to power it (and trigger the cycling) rather than just doing the same thing but with a timer plugged into 240V.

              • rumblytangara on 19/09/2024 - 10:10

                @Prong: I think that for rigorous testing, you'd have to strip the LiPo packs out so as to bypass all the electronic variables (the electronics in the power bank as well as the device being charged, because the latter determines discharge rate which could fluctuate over time).

                You'd then end up with discrete packs that could be hooked up to a hobby charger that looped charge/discharge cycles.

                The idea of having this powered for free is a neat one. Especially if it could be done in parallel with other packs. A comparison across a spectrum of brands would be really useful, but the setup would be fairly complex.

                My own observations have been totally random. Have had good cells deliver power after five years sitting in a drawer, and carefully managed cheap cells die within two years.

                And I suspect that the manufacturers would change their sources every once in a while without notice.

                  @rumblytangara: Yeah testing the bare cells would be ideal. I have done it on various other cells using a load tester (so it can be set to draw a constant power level), and it's simple enough. Doing a B6 teardown is on my to-do list, but I wanted to actually film it properly and it keeps ending up in the do later pile.

                  But yeah cell quality can be very variable. And some are fine for years, whereas others develop internal shorts and die quickly. Iniu at least (I believe) is from the factory producing the cells, so they have total control over cell quality. No wonder they are happy to give a 3 year warranty!

                  I have experimented with doing direct efficiency testing of the circuitry from a dead power bank. It's a pain though, as the circuit includes the battery BMS, and the one i tried didn't work correctly without being connected to actual cells.

                  Longer term wear testing with the power bank intact is probably ideal though, as it most closely replicates what an end user will experience. Doing multiple charge cycles a day to try and gauge wear in a shorter period may not be very accurate, if it keeps the power bank at an elevated temp, and gives the cell chemistry less time to equalize. Interestingly for most accurate testing, it would be good to replicate the typical charge cycle of the most common deice charged. EG for a phone, the charge wattage trails off.

                  One of my load testers is programmable, so I have experimented with doing charge cycling, and logging every discharge cycle. But that's overkill really, and it would be fine to just test the capacity every X number of cycles.

                  Cycling multiple power banks would be very easy. Just have all their chargers on a powerboard with a timer. And a relay and load for each – small load testers are a few dollars from China. Either adjustable wattage with a heatsink and fan, or if doing ~10W or less, then then are fanless resistor based ones.

        That's the box dimensions. INIU is great at making power banks, but not so great at good Amazon product pages.

        It measures in at 13.6 x 7 x 1.5cm. The 210 grams is accurate.
