        I think the limit is around 30000mAh usually - this shouldn’t be too big to take with you. It’s to stop people taking stupidly humongous batteries that could power the whole plane

          30000mAh is over the limit. Cut off is around 27000mAh so this squeezes in the limit without needing prior permission from the airlines

        This is just under 100Wh so it's fine to be taken on a plane. If it's over 100Wh and under 160Wh (e.g. 30000mAh) then you need prior approval from Qantas/Jetstar and declare it at check in with Virgin.

        • 900dollaridoos on 22/02/2022 - 14:34

          Wh = V * Ah
          OP's link says that its a 9v battery.
          So wouldn't this be over the qantas limit since:
          9v * 26.8Ah = 241.2Wh?

          • AssociatedClear @ Romoss AU Direct on 22/02/2022 - 14:40
            +3

            @900dollaridoos: You're misreading somewhere because the cells in power banks are not 9V. They're 3.7V so it's 99.16Wh.

            The power bank is capable of doing 9V/2A charging as part of the USB Power Delivery and Qualcomm Quick Charge protocols.

              @Clear: Thanks for the info. Must be an amazon error as they have it listed as 9v in their description.

                @900dollaridoos: Yeah I see where it is. I think they intend on implying that's the voltage it can output as.

                A general rule of thumb is that power banks for phones will have their cells rated at 3.6V or 3.7V.

            @900dollaridoos: To add: all lithium cells are 3.6 or 3.7v (depending on the chemistry). There is simply no other voltage. (Anything else comes from bundling cells together, and/or adding voltage regulating circuits).

      I'd say Romoss, anker, xiaomi all up there as good brands (and nowhere near as expensive as the rubbish at jbhifi/harvey)

      • ozhunter68 on 22/02/2022 - 11:34

        Yep, cell quality and safety features are good for all three brands.

        Other features wanted such as USB C PD 18W + and much more up to 100W for laptops etc,

        as well as multipple port availibility and high Total W output ( using more than one port, or all together ),

        or display type/options will depend on which model you need/chose and your budget of course.

        This particular model has a great mix of ports and display features ( can see Amp and Watt draw as

        well as voltage which is handy and fun to use ), and one of Ozbargains favourites over the last few years

        since release. I have bought/used over 20 powerbanks and this is up there as one of the best for features,

        quality and value. But keep in mind it is high capacity so fearly large and heavy.

      No it doesnt. Measured amps go to 0 when I try to passthrough

    • aldroid on 22/02/2022 - 18:17

      I have the SW20PS+ which is basically the same unit but 20000mAh and it does passthrough so it's suprisingly that this model doesn't.
      EDITED: be aware that only some of the ports are auto-sensing bi-directional so it will depend on which ports you charge to/from.

      • ozhunter68 on 23/02/2022 - 11:24

    2022 Gen 1 Mobile phones and laptops support 45w to 120 watts. Eg; S22 ultra, x5 pro

    • krisspy on 22/02/2022 - 10:53

      Samsung learnt their lesson with batteries. The s22U seems to only blip on 45w just for the sake of marketing. Most reviewers who compared 25w to 45w only showed a difference of about 6% after 20mins of charging.

      Even my s21U only charges at full 25w when in optimal conditions. Ie. Screen brightness down or screen off, as soon as it gets warm, it throttles to 8w. Gaming, gps or watching a video throttles charge rate.

    I find these huge powerbanks just a bit too big and heavy. Prefer the 10000mah ones unless taking a seriously long plane flight or camping in the middle of nowhere for a week.

      +2

      Agree. These are great to have even in case of power outage, and like you say camping or bus/plane/train trips.

      But the most used size weight powerbanks are the thinner/smaller/lighter ones you can easily put your

      phone on and still hold with one hand, or in your pocket without your pants falling down lol.

      I find between 5000mAh to 10000mAh the sweet spot, but also have one of these and bigger for longer trips too.

      • [Deactivated] on 22/02/2022 - 11:48

        Depends on dashcam. I once left mine plugged in, 24 hours later and got cir 50% remaining viofo a119 on a romoss 30000mAh… I have also once left it there for 48 hours with 30% battery remaining.

        Usual practice is plug in when the car is park outside (eg shopping centre) and back to the cars power socket before driving off.

        • aldroid on 22/02/2022 - 12:19
          +3

          Why don't you plug it into a power bank that supports passthrough charging that's permanently connected to the cars power socket? Effectively acting as a UPS. Then you wouldn't have to switch plugs all the time.

          • [Deactivated] on 22/02/2022 - 12:29

            @aldroid: Too much effort to find one.

            I got a blitzwolf and a romoss at home. Cbb figuring out whether they are 'passthrough'.

            Also, constantly charging a pwrbank is not ideal for longevity, i suspect.

              +2

              @[Deactivated]: Hahaha whatever dude. Replying to my comment was more effort than it takes to find out whether a powerbank has passthrough charging or not. The slight reduction in battery life is a small price to pay for the convenience of not having to switch cables constantly. FYI, I've had a Xiaomi 2 port powerbank permanently connected to my cigarette lighter socket for about 4 years. It's very convenient for when I'm charging my phone in the car as it means when I stop to get petrol I know that the charge cycle will not get interrupted plus the voltage spike when you start the engine can be damaging to phone batteries. I rather sacrifice a $20 power bank than a $500 phone.

                @aldroid: ///This/// I fully agree with your outlook. Power banks are relatively low cost tools and work horses to make our life easier. Whether it last 3 yrs. or only 2 yrs. with heavier more reckless use (such as leaving it in car over summer where it may be needed) is small price to pay for the much added convenience and peace of mind. I buy 1 to 2 new power banks a year (after initially purchasing many lol) and enjoy new tech and features and just hammer the older models.

    • Caped Baldy on 22/02/2022 - 13:58

      I had considered this but I'd be too worried about leaving a big battery in a car during hot days. I think it's a matter of when not if for the battery to fail.

    I got approximately two years out of it. Flaky now. The USB C port refuses to charge any devices. The other ports still work. My hunch is the heat got to it. It would get warm when charging the 18w and then when I also loaded another device to charge it would get warmer. Constant use like this I think broke it. Last time I used it… it had Switch and two iPads connected to it. This was on a trip and I was the only smart one to bring a powerbank. USB C never worked after this trip.

    • Toffcuz on 22/02/2022 - 11:07

      • UFO on 22/02/2022 - 11:33

        Wot? Then why in the world would the power bank have multiple outlets of the same type??

        Copy pasta
        “3 USB outputs enable to charge a mobile phone, a tablet or a Nintendo Switch simultaneously at maximum speed up to 3 amps”

        If the brick died because of multiple devices, that’s not user error that’s poor quality power management on the brick.

        Good quality powerbricks will handle that power draw properly and not it to overheat and get damaged.

          "UFO" Although you are technically correct, and I agree that you should be able to use

          all ports at once to it's max possible output on a hot day without one or more of the ports failing or

          permanently causing damage. Unfortunately in the real world this does not seem to be the case with

          all types of usb chargers, 240V wall chargers, car usb chargers as well as powerbanks, mainly when it

          has usb C PD as well/or high Amp output usb A and both, especially when using 2 or more outputs

          together. I'm sure some brands and models are more prone to this failure than others, but many

          seem to have this problem eventually.

          • UFO on 23/02/2022 - 13:35

            @ozhunter68: everything you said was correct, except for the all added to the start of the 4th line.

            not all chargers are created equal, and some will definitely perform as a user would except. Just not at these price points. Like nearly everything, you get what you pay for.

            • ozhunter68 on 23/02/2022 - 13:48

              @UFO: I did not mean all as in "all brands, makes and models", but "all types of chargers." If you spend more to get better brand as well as a model that can easily handle your needs with some buffer kept in reserve, the chances of failure would lessen. You still hear of failures, but time will tell how long these will last with regular use as they have only been out for few years for the more powerful models and GaN chargers.

    • ozhunter68 on 23/02/2022 - 11:38

      All I can recommend is work out what your minimum charging needs are, your budget, then look for that within the decent brands. Personally I find the Kogan Branded power banks decent for the price when on sale or free delivery. They have a decent 10000mAh wireless 10w out power bank also with 18w USB C of and qc3 in/out for $35 sometimes, then delivered free is bargain.

  • OzBestDeal on 22/02/2022 - 11:44

    Fully recharging the 26,800mAh power bank only costs 11 hours with 18W wall charger.

    Charging with standard 5v 2amp will take close to 20 hours

          The 30000mAh you linked is an 18W power bank and the difference between the 26800mAh and what Tzeeman linked is the 30000mAh has no display

          The other 2 linked have no 18W fast charging. Romoss call them 'fast charging' because prior to USB-PD and QC, 2.1A charging was called fast charging under the USB standards.

      When you say "small laptops" your going to have to get more info on how many watts and volts your system wants and/or needs. I have various Chromebooks and a Lenovo Thinkpad 11.6" that charge via USB c pd, and although I find most Chromebooks can charge with the least amount of watts, some can be fussy with voltage needed. I had a Cygnet Pro 60W 20000mAh power bank that would charge 3 out of 4 Chromebooks and my small Thinkpad, but not a Lenovo S330 14" Chromebook, yet a small 6000mAh USB c 15w max $8/$10 Aldi power bank would. It's more to do with Voltage/charging tech compatibility that makes it charge or not, then higher wattage just makes it faster.

              @xoom: We are on same page. All depends on your budget and needs. The more watts output the better lol.

    Do you know if we can recharge a macbook pro off this battery? (late intel version)

    • ozhunter68 on 23/02/2022 - 08:38

      Will only really slowly trickle charge when your not using it if your lucky.

      Get a 45W minimum powerbank and higher if your budget allows.

        Any suggestions on a particular powerbank? I am after a laptop charger as well, but don't even know where to start

        • xoom on 24/02/2022 - 10:14

          You can start here.

          Xiaomi ZMI QB823

    I have one, brilliant, and about to buy this one

    I just got this powerbank, is the display meant to flash while it's charging?

    • chubbyboy on 24/02/2022 - 20:40

      Mine flashes on charge too. Also just tried charging my iphone with it, the power bank dropped 25% and my iphone charged 5 % ?? wtf ?? product seems dodgy

      • chid on 25/02/2022 - 10:26

        yep mine dropped from 72% to 0% after plugging it into my phone after like 5 minutes, and now it has 'charged' 0->43% in 24 minutes at 18W (measured at plug at ~18-20W)

        anyway I'll give it a few cycles, hopefully it fixes itself (as part of the battery activation)

        • chubbyboy on 28/02/2022 - 08:04

          I drained it out of the box and then fully re charged it, took 24 hours but it seems to be working more accurately now, got a full iphone charge off maybe 15%

  • Ron280 on 28/02/2022 - 16:27

    The instructions state to only use the factory supplied charging cable and power adaptor. I only received the power bank. On the box, it states that only the power bank and manual is inside. Confusing.
