    Links to 20,000 mAh power bank.

      It links to a listing with that title, but it has options where you can choose different capacities.

      • UncleRico on 10/05/2023 - 22:22

        Indeed, but it still shows 20000mAh in cart even after choosing the 30000 mAh option.

        As noted, it does have a note under the listing saying 30k, so here’s hoping that’s what gets sent out. The 20k model looks older and larger, so fingers crossed.

        Thanks OP - great price, if honoured.

        • deva5610 on 10/05/2023 - 22:25

          But again in the cart underneath the where it says "Baseus Portable 20000mAh Power Bank PD 20W Fast Charger Backup Battery" it also says "30000mAh" and the same thing again at the checkout screen.

          It's for the 30,000mah version.

            @deva5610: Er yes, that’s what I said. Still less than clear and contradicts the item name, so not entirely without risk, but let’s hope it is indeed the larger capacity unit.

            • deva5610 on 10/05/2023 - 23:29

              @UncleRico: I don't actually think you did.

              You said 'Indeed, but it still shows 20000mAh in cart' but didn't mention the 30,000mah note that shows in the cart as well. You only mentioned that for the listing.

              Was pointing that out as well for the benefit of others who might have also missed the note in the cart.

      The 30,000 is likely cheaper because of this reason, its more of a hassle to take on airplane trips than the smaller 20,000 model. More hassle = less desirable despite its technical merits.

    • Prong on 10/05/2023 - 23:34

      • Prong on 11/05/2023 - 20:10

        Baseus rate the conversion efficiency as ≥75%. And give a real world capacity of 18,000 mAh at 5V 3A. Which is 90 Wh.

        90 Wh means real world 81% of the 30,000 mAh (111 Wh) makes it out of the power bank after efficiency losses.

        I tested it from 100% to zero and got ~ 85% of the 111 Wh. So 95 Wh, 25,500 mAh useable.

        So better than rated. And pretty normal for this sort of price range. Higher end power banks will have more efficient voltage conversion (90%+), but for $30 this power bank is a good deal.

      maybe 645 gms - if similar to this - https://www.f2parts.com/product/baseus-power-bank-bipow-digi…

      yeah sounds heavy which I guess is why they deliberately did not show the weight in most webpages - it took me some googling to find the above link

      I'm happy with my 10000mAh Anker PowerCore A1263 which is 180gms and fits easily in my pocket even when attached to my iPhone. I got it for about $30 sale price a few years ago from a Bic Camera in Japan and have been happy with carrying around.

      I'm guessing you won't want to carry a 645gm mofo in your pocket - unless you're fitted out for backpacking or such.

    • ShoeyAU on 11/05/2023 - 07:20

      With 20W, it definitely won't whilst the laptop is in use. With the laptop off, it might trickle charge - but YMMV.

      • shbshb on 11/05/2023 - 07:33

        OK thanks, will give this one a miss.

      • Chazzozz on 11/05/2023 - 07:44

        It will also largely depend on what kind of laptop it is. My wife can easily power & charge her M1 MacBook Air from a 20W battery, even while in use. My Lenovo X1 Yoga will suck it dry pretty quickly, irrespective of whether it’s running or powered off. Ergo - great backup for low-drain devices but only useful as emergency power for larger ones.

        • ShoeyAU on 11/05/2023 - 08:14

          Good point, theres a lot of variable factors. I did recall buying a 45W powerbank because it was delivering sufficient wattage to actually power a laptop. But in reality, when I did so, the % charge on the powerbank would drop so fast it is not a practical substitute except for emergency.

      • Hangryuman on 11/05/2023 - 11:28

        can you charge your laptop from an electric bicycle battery ? ;-)

    • Prong on 11/05/2023 - 07:57
      +2

      It does 12V, 1.5A. (or 9V 2.22A, or 5V 3A) from the USB-C port.

      Some laptops will charge on 12V via USB-C. So it depends on your laptop, and you will have to look up it's spec.
      If it does, 18W (or 20W at 9V) will be enough to charge it while off, Or very slowly charge it / keep it from losing charge if in use for non intensive tasks such as web browsing.

      Generally to be sure, you need a power bank that does 20V output, and 45W+.

          I don't have any experience with Veektomx, but it's probably decent enough. I think there are better deals atm if you have eBay Plus or sign up a free trial.

          The Baseus deals stand out currently IMO on the cheaper end. There's plenty of fantastic power banks at the higher end, but they are more than double the cost and not really worth it in most cases.

          I just bought the 100W, 20,000 mAh Baseus Blade power bank for $70.54 with eBay Plus.
          It's thin but wide form factor, so great for putting in laptop bags. But some people prefer a more square layout.
          The reason I got it was for passthrough charging - it's one of the few power banks where you can plug a USB-C charger into the power bank, and then plug the power bank into a laptop.
          https://www.ebay.com.au/itm/313961826214

          Or a more standard shape, 65W, 20,000 mAh Baseus power bank for $63.07 . Slightly smaller (in terms of volume) than the Blade model, but 65W vs 100W and no pass through charging (which is not a feature you may need).
          https://www.ebay.com.au/itm/314469276529

          Or if max charging capacity is needed, then the Baseus 65W, 30,000 mAh power bank is $71.37. It's basically the same dimensions as the 20,000 mAh, but 1 cm thicker. I have one of these and think it is pretty good. Keep in mind if you fly with it, you need to seek permission from the airline before travelling with it.
          www.ebay.com.au/itm/313648965957

          This recent deal for a 50W (45W from USB-C if laptop charging) Xiaomi 20,000 mAh power bank is reasonable too if you want a bit cheaper - $58.09.

            @Prong: Such a comprehensive reply! So generous. The lappie is a HP Probook 435 x360 G8, 13.3" FHD Touch, Ryzen 5 5600U, 16G, 256GB - it came with windows 10 and I upgraded to Win 11 so I have a bigger problem with battery drain somewhere that has got me stumped, so the battery is a bandaid.

            • Prong on 11/05/2023 - 20:30

              @dtoovey: Happy to help - I was comparing them anyway for usage with some other projects.

              Looks like the HP laptop only supports 20V, and lists max operating power as 45W. So any of those power banks would work, but you can't get away with a lower voltage one (like gooloo power bank)

              A 65W one would be best if you need to use it while charging.

              Windows can be a pain for doing weird thing with power modes. If you have not already, I would recommend a clean install of Windows 11 after an upgrade. You can factory reset from within Windows, but ideal is creating a bootable USB drive and doing a clean install. It's pretty quick and easy with the Windows tool, and Windows 11 will (should) auto activate again once done.

              I find a clean install sorts a lot of problems.

        • CodeXD on 11/05/2023 - 09:44

          It is worth looking at the laptop's tech specs to see what the type-c port is capable of. Not all C ports can do charging, some are just for display or data transfer.

          • Prong on 11/05/2023 - 10:05

            @CodeXD: Excellent point. dtoovey, post the laptop model if you want it double checked.

            FYI, the gooloo chargers appear to only do 12V output at best on USB-C, so won't charge most laptops.

    Bought one, first power bank I have owned. Was at 40% when turned on, about 10 hours of charging it had got to 83% and basically not going any first. Using 9v and 5v chargers and still seems slow or not progressing. Changed micro USB cable no difference. Maybe a lemon? How’s long should they take to charge to 100%? Charge quicker via a PC?

      • Prong on 19/05/2023 - 11:53

        Charging via USB-C or micro USB?

        I get the full 18W charge rate on USB-C with a charger that does 9V. But I did not try the micro USB cable.

        Even at 18W, inefficiencies will mean dead flat to full will take 8 - 10 hours.

        I suspect dazzza is seeing an issue where the voltage droops too low to do the final bit of the charge, which needs ~4.2V at the battery. I am curious, so will try and replicate it.

        • UncleRico on 19/05/2023 - 16:06
          +1

          I only tried the included micro-USB, but did not have any issue with it charging all the way to 100%, beyond the 12 hours it took from the delivered unit which was bone dry and 100% charge.

          Will try with a USB-C cable and see if it charges more efficiently.

          • Prong on 19/05/2023 - 18:55
            +1

            @UncleRico: Yep ok, I get the same.

            Though for me, I can't get 9V, 2A charging via micro USB.

            It will do about 10W charging with 5V input of 2A. Which matches to the 12 hour charge time you experienced.

            The power bank appears to judge capacity via voltage, not counting ingoing / outcoming charge (perfectly normal for a power bank). So holding in the 80% range would be normal until it accepts enough charge and the voltage rises. So the final jump to 100% could appear to happen very rapidly.

            So possibly dazzza's power bank just needed to charge longer. If was only getting 5V, 1A, then 24+ hours.

        • dazzza on 20/05/2023 - 00:17

          Tried both c and micro, better success with C

            @dazzza: Yeah nice. USB-C (on both ends) plus a 20W or higher charger that does 9V or 12V will allow you to reach the max input of the power bank.

            But it will always be fairly slow, at 18W, because of the high capacity. About the quickest you might see is 7 hours.

      There is a good chance your chargers combined with the micro USB cables are creating the issue.

      I know it does not come with a USB-C cable, but can you try charging from USB-C?

      To me, stopping at 83% points to the battery not getting enough voltage.

      The battery needs 4.2 volts or so to reach full charge. Micro USB is not always great at higher charge voltages or rates, and the charger may be defaulting to 5V, at 0.5A or 1A. And then when the power bank tries to charge off that, the various losses in the system may result in under 4v getting to the battery, and at low wattage. Which won't charge the battery past about 80%. The final 20% of charge needs higher voltage.

      Ideally, charge it with USB-C from a charger that can do 12V, and 20W+.
      Or at the very least, a USB-C cable from your current charger.

      Keep in mind that even at the full charge rate, it will take almost 10 hours to go from dead flat, to full. Leave it on overnight.

      If it still does not charge past 83%, then it may be faulty.

      It's an interesting issue, so out of curiosity I will try and replicate it with the one I have.

        Eventually got past 83% after trying differet chargers, cables and power points. Which one worked…. i dont know!

      After a bit of testing with my one, I think what you are seeing might be normal. Just leave it charging for longer and it should hit 100%.

      Mine does not seem to switch to 9V 2A when charging via micro USB. It might not actually accept that, or it might need a specific charging standard.

      Your best bet for faster charging is via USB-C. Even a USB-A to USB-C cable should do 9V fine, and give you full charging speed.

      It's kind of crappy for Baseus not to include a USB-A to USB-C cable with the power bank.

        Yeah, took a while but got to 100%. Seemed to have more success with usb-c cable but still slowish.
