  had enough of Baseus products now…

  i had a wireless car charger that failed and ended up getting refunded and this one also ended up getting refunded…

  i dont know if anyone else is experiencing it but just having an apple usb-c cable connected to it, the powerbank will drain power even though no phones are connected on the other end…

      Lightning cables are active - leaving them plugged in will drain powerbanks.

      See here.

      Make sure you do not leave a USB C to lightning cable in the portable battery (with USB C PD port) when the power bank is not used. The USB C to lightning cable will drain power automatically even though there is no device connected.

      Not sure if the same applies to Apple usb c-usb c cables as well.

        Some powerbanks will turn off the output when there is no or a low current draw which prevents this problem

    I also bought this recently because of super fast charging..

    It's great when it works.. When it works..

    When charging the battery pack at around 60% charge, it struggles to charge any more up to 100%. The screen shows 20v charging buy 0.00A.

    And I often have issues trying to charge my phone with it.. It would charge for 30seconds then disconnect..

Then I charged it and after 10 minutes it said 100%! This doesn't seem right at all. None of my other batteries drain from sitting there doing nothing.

    Yeah QC seems to be severely lacking of late. And frustratingly Baseus choose to just sell the power banks anyway and deal with pissing people off rather than eating the cost to check and repackage them.

    Hopefully it is just a covid related supply chain issue and quality on new gear will be better. At least Baseus seems ok at replacing or refunding.

    That said, if you get a working one (I seem to have) the Blade is a pretty good power bank for $69. There is nothing else comparable. Especially not that can do pass through charging at up to 65W.

  20000mAh at what voltage? I'm no electrical engineer, but my understanding is this figure is useless without knowing the voltage.
  It has a range of voltages, so I assume that is at the lowest, 5v. Or maybe even 3.7v from the underlying cells.

        Your question doesn't make sense, batteries are calculated in mAh, voltages don't matter in that case.
        Example, you have a 100L tank of water, if you have a larger hose then you would use up the 100L faster, just like how using 20V 5A, you would use up that battery faster than charging on 5V 5A.

        Your underlying question depends on what you want to charge, instead you should find out the capicity of your device I.E iPhone 15 Pro Max has 4323 mAh, then this charger would be able to roughly charge that device less than 4.6 times.

          @jerjergege: My underlying question was trying to figure out why this small battery with 20000mah has more capacity than my ebike battery of 14000mah and whether I could also use this to power a 24V 3A device for 10 hours. The missing link is the voltage used to calculate the mWh.

          I assume your iphone example only works because the voltages are the same. They certainly aren't with my ebike battery, thus the equation wouldn't work.

            @xmail: The easiest way to compare capacity is Wh. Which is voltage x Ah.

            The Wh rating is provided in the spec on the eBay page. 74Wh.

            Your e-bike battery is likely hundreds of Wh, depending on the voltage.

            Also in the listed spec, the power bank gives you the batteries internal voltage and capacity. 14.8V at 5,000 mAh.

            It also gives you the equivalent mAh capacity at 3.7V, which is the standard used for listing power bank capacities in mAh. In this case 20,000 mAh.

            For good measure, it also gives you the rated capacity under load when providing 5V, 3A. 12,000 mAh.

            Just in case you didn't want to do the math yourself, it then gives an energy conversion rating. ≥ 75%

              @Prong: Yep I understand, I just didn't see the voltage or the Wh in the post. Of course I realise my battery runs at 52V thus many more Wh.. it was used to illustrate why the mAh was useless to me and the ridiculousness of this being used to charge it. The title and ozb post just claims mAh, which I guess is supposed to be imply 3.7V for these types of devices, and people are accustomed to only seeing these.

              @jerjergege explanation is nonsense unless you assume everything runs at 3.7V, which I wasn't given I was asking for the voltage used for the mAh measurement.

    They are asking about the voltage the cells are rated at.

    If the cells are 3.7v for 20000 then if there is a voltage draw of say 5v there actually less than 20000 in capacity.

            @FOGO: I thought my analogy was good, water capacity = battery capacity, and the larger the hose the larger the flow, just like how the larger the wattage charging a device requires, the faster the battery drains.

            I just skiped what the voltages or current is, it doesn't matter in the analogy because if the hose size were to increase, so does the watts.

    I just tested it and the 100W Blade model from this deal charges fine from 5V. At 5V, 0.8A, it is telling me it will take about 5 hours to go from 76% to 100%!

    I suspect the issue you are having with the 20W power bank is voltage drop when charging at 5V will make charging very slow, and may not give a very accurate % until full. I have the 30,000 mAh version and can replicate similar.

    The 100W Blade power bank does not have this issue, as internally it runs at 14.8V, so has to step the voltage up when charging from 5V. And it has a much more sophisticated system to measure battery capacity.

    I speculated a bit on this down the bottom of a recent Baseus deal where someone was having a similar issue.
    https://www.ozbargain.com.au/node/773828

    Your power bank may be charging, just very very slowly. Or internally the voltage drop may be enough that the battery is not getting enough voltage to charge beyond a certain point. You could try leaving it charging overnight and see if it ends up fully charging. The voltage percentage display likely uses a fairly simplistic system, so may not be very accurate when charging.

    Ideally the charge circuit should include the ability to step up the input voltage so the ideal charge voltage is always achieved. But likely it only includes circuitry to step the voltage down when charging at higher voltages using a PD charger. That's perfectly normal for a power bank at the lower price points.

• 

  Zackeroo on 26/05/2023 - 11:13

  I have this same powerbank. It does charge at 100w, although the biggest issue I have with it is that the battery percentage isn't always accurate. Sometimes it doesn't charge past 90%, and sometimes the battery dies at 10%

  For those who have this power bank, is it too large for everyday use? I used to have a 20,000 mAh powerbank in a thicker form factor that was quite unwieldy for most uses, ended up just going back to my 10,000 mAh capacity one.

  • 

    Prong on 26/05/2023 - 13:40

    +2

    For the capacity, it has a higher volume than many other power banks. It does not feel small in the hand and is not one that you can put in a pocket.

    That said, the form factor means it is very easy to slot into a laptop bag, or other storage areas of bags that don't really handle a thicker power bank. I much prefer it when putting it in a bag compared to thicker power banks, but it really depends how you intend to carry it.

    There are very few good options for a high output but slim power bank. Especially not at this price!

    There is a more compact (same thickness) version coming, but who knows the ETA or price in Australia.

    A key factor that led me to buying the Blade power bank was pass through charging, at up to 65W. Super handy when using with a laptop, and very few high wattage power banks offer pass through charging.

    As it happens I also have the 65W, 30,000 mAh model. I got it to use with a custom PD trigger cable to run a camping fridge. It appears to work well, and the capacity checks out.

    Appears to be ~$73 on eBay atm. That's cheaper when I bought it on special a few months back.

        The good news is that in this case, pass through charging causes zero issues for the battery.

        Power is renegotiated each time devices are plugged in. Power from the charger is sent directly to the output, just like in other devices (such as hubs) that do pass through. Whatever power is leftover is used to charge the battery. The battery will charge slower since it is last in line for power, which will actual improve battery longevity vs fast charging.

        The battery cannot output power in passthrough mode - it can only be charged. If the devices connected to the outputs of the power bank attempt to draw more power than the charger connected to the input can supply, then the power bank will disconnect them all.

        Baseus limit the output power to a maximum of 65W in pass through mode. So with a 100W charger, there is more than enough power to pass through, and to charge the battery.

        You might read articles that say things like pass through charging damages the battery through extra wear, or heat. Neither are possible here. The battery temperature is monitored during charging, and charge rate limited if the temperature is too high. That is how it works if charging during pass through, or just normally. Extra wear does not happen, since the battery can only charge.

        Certainly in the past more basic power banks might have had issues with pass through charging if the circuitry was not built to do it correctly. But in any decent power bank it is not an issue at all. The reason why more manufacturers don't include it is because it costs more due to slightly more complex circuitry.

  I had one of these and loved it but unfortunately left it overseas at a relatives house.
  I like the form factor for keeping it in my backpack.

  I'm tempted to get another but I don't really use it unless I am travelling. Might just wait for the new version to be available here.

  The 65W version doesn't activate the PD mode with any of my ThinkPad laptops. (While my older Xiomi works fine)
  Works fine with the with the mobile phones though (Fast charge)

  Recently got this one for my Lenovo Yoga Laptop, also for Galaxy Ultra & a tablet. So far its working fine with all devices, but needs to keep working for sometime longer before I give it full praise. My reasons for choosing this one included:-
  a. Will charge my laptop when ac power not available
  b. Design, flatter depth to fit inside bags (width not an issue)
  c. Simultaneous charge/discharge
  d. Display of how much charge is left (no matter how accurate some indication is great)
  e. 20,000 mAh can take on all planes without issue (unlike 30,000)
  f. Number of ports available is a bonus for my phone & tablet

      Possibly, but could not find brands like Anker displaying power remaining (important info when on the go) which would charge my laptop and be within 20,000 mAh to be allowed on flights.
      It is deserving of it's design award, so far i'm impressed, so if it continues would consider upgrading to the new 22% smaller Blade HD model when it becomes available at a reasonable price - see @futaris comments earlier.

        i just read prongs comment and realised it does pass through charging which is a big deal i didnt realise

        all thats missing is a wireless charging pad integrated

    Yeah wish I knew this a few months ago All I saw was how great baseus is. I'm away at the moment and tried to charge my phone, the power bank went from 100 to dead and my phone only went up 10%

    I then charged the power bank and it went from dead to 74% in a couple of minutes. So this is either faulty or fake. I bought it from the same eBay store in this deal, but it's a 65w 20000 mAh one

  Yikes. Quick ebay search and already found an owner selling theirs because of faulty PCBs.

  Bought this on previous good experience with Baseus, so far working good, I think it should be fine
