    i under estimated how heavy this was when i bought it

    only carried a couple of times in the back pack when i went on holidays recently

    • Namidairo on 09/10/2023 - 09:57

      Yeah the jump from 10000mAh to 20000mAh is where it crosses the line in terms of portability for me, let alone 30000.

      Having to fill out the form for it every time you travel overseas probably does not help.

      • Archi on 09/10/2023 - 10:38

        didn't need to..

        my back pack had a 30,000 and 2x 10,000

        they didn't say anything… JAL

    • bamzero on 09/10/2023 - 12:27

      Check out their 60000mAh at 1.3kg :)

      I have the Baseus 30000mAh which is pretty chunky to carry around but seems to go forever.
      It's the 65W in/out that I like on it though so can use with my laptop and recharge it quickly. That 11 hour recharge at 18w on the Romoss bit slow, mind you the Baseus cost me $65 not $40.

    FYI, most airlines have a 100w limit without requiring airline approval, including Qantas. For batteries from 100wh to 160wh, this requires a special approval process that I haven't ever needed to do, but even if the Qantas process is smooth, I'd bet other airlines would be trickier. I'd say avoid this if you plan on travelling, especially internationally.

      Yep, just take two 20000mAh ones instead.

    • aaronsd on 09/10/2023 - 09:55

      Been on Qantas, Air New Zealand, Fiji Airlines and South China Airlines in recent times, all international flights. Both wife and I have battery packs that fall into the 100Wh-160Wh range. I even got through Beijing without being able to speak any Mandarin. Only in China did the carry on security check person check the batteries closely, he saw the label that stated it's below 160Wh and let us both through. This is with me having other battery packs too: 3-pack of GoPro high capacity, laptop battery, phones etc - no issue at all.

      I've never done that airline approval, feels a bit archaic in all honestly with how many batteries people carry on them these days.

      But you're right though, strictly speaking, the airline can confiscate, so buy at own risk for travelling on flights. All I can say is that if I got through Beijing as a foreigner without speaking the language, most people will do fine in most places of the world.

      Also it might be more nuanced since I don't see this approval text in the Air New Zealand rules (https://www.airnewzealand.com.au/travelling-with-lithium-bat…), but the other 3 carriers I mention seem to state it in some form now that I've checked. Probably why airport security doesn't seem to pull you up on it.

        Fair enough if you want to take the risk, I'd rather avoid it. Looking at some comments on TripAdvisor and Reddit over the past few minutes, I see that a few passengers noted that European countries seemed to be more diligent with checking the powerbank capacities rather than countries in Asia.

        Still though, as jv said, why wouldn't you just take two 20k powerbanks, or a 20k+10k?

        I just came back from a 3 week trip in Asia, carrying around a 10k powerbank. Used it once for about 30 mins. I could have taken a 5k powerbank and had capacity to spare. I think you really need to assess if you need to take a 30k powerbank. It's much heavier, bulkier and carries an inherent risk of something going pear shaped at an airport.

        It's not a hangover from COVID, the policy is in place from CASA. https://www.casa.gov.au/operations-safety-and-travel/travel-…

        Lithium ion batteries 100–160WH
        These are more powerful batteries. You can find them in equipment such as power tools and mobility aids. They’re usually between 100 and 160Wh.
        If you want to carry these kind of lithium batteries with you, you must get approval from your airline before flying.

          I feel like more batteries, more risk of shorting one and causing a problem tbh. I would argue something at 20Ah that is poorly packed is still very dangerous. Have seen plenty of people shoving them in their bags without caring at all about potential short circuit.

          I am cautious when I pack my batteries for travel - the GoPro batteries I keep in the little 3-Pack container to protect them. The power banks I put each one in its own zip lock bag because I've seen too many scary videos of lithium batteries blowing up in bags.

          For me I use the power bank when I go on hikes and longer day trips when I travel - it's very convenient to be able to charge my GoPro batteries on the go in my backpack using the one large power bank - that's mainly the reason for it for me personally so I get it that it's not for everyone. The GoPro seems to be very efficient at converting that electrical potential energy to heat energy haha… And I just don't have to be mindful that I can only get about 3hrs of charge into that power bank at the end of the day before I go to bed - so it'll be good to go for a couple of days at a time if I get down to about only 30% capacity in the battery pack after one solid day of usage.

          Interesting finding about European countries, I'll be more careful and carry just one 100-160Wh pack between us to test the waters if we ever end up travelling that far from home.

          Noted on the CASA reqs though, that's undeniable for Australia. Glad to see Air New Zealand blanket allow it up to 160Wh which imo should be the norm anyway.

          Maybe the CASA rules should state that power banks must be stored in their own zip lock bag when taken on board an airport instead to actually make a significant improvement on safety lol

        Recently flew Air NZ and Qantas with a 114Wh pack. As far as I read Air NZ doesn't require approval but I got the required approval for Qantas (which is valid for 12 months). It was a mission at check-in though, the staff obviously not familiar with the process. Took her ages to work out how to log it in the system, had to call in the supervisor to help. Got there in the end but tempted to not bother next time and just take it through.

      Qantas is the easiest as you're covered for 12 months and includes Jetstar. Others like Virgin require you to declare everytime.

    • realist123 on 24/10/2023 - 09:35

      I flew Adelaide to Alice return last week. Adelaide waived me through, Alice I had to get it inspected.

  • jv on 09/10/2023 - 09:49

    has 100-160Wh guidance,

    111Wh

  • harvestloon on 09/10/2023 - 09:52

    I don't use this one for overseas travel to avoid even checking each flight guideline on watt hours, and take a smaller 10k or 20k mah that will be sufficient and weigh a lot less.
    However, around the house, camping or in the car this bank is a reliable beast. Got mine in 2020 for $35 a piece and it has a seen a huge amount of use.

    • dav3 on 09/10/2023 - 10:21

      Yep have one of these in the collection for emergencies and camping, the only issue I've had is that (from memory) it powers down if the power draw isn't at a certain level, ie. if my LED lights are set too low they turn off after 5 minutes, if you turn them up they stay on.

      • haz on 09/10/2023 - 10:27

        I think that's a common issue with most powerbanks, it power off when the current draw is too low. I'm not sure which one in the market has an 'always on' function, which will be useful for low or no current draws. I have tried to use a powerbank for a tent led light which has a separate on/off switch. Once the led lights are turned off for more than a few minutes, the tent switch light cannot turn on as the power bank is completely in an off state.

        • dav3 on 09/10/2023 - 10:55

          I understand the functionality, but I've found some to have a lower threshold than others. I think generally the bigger the battery the higher the minimum draw. I have a couple rated around 10000mAh and they're generally fine, the 20000-50000mAh ones are less tolerant of low power draws.

  • Rilo 117 on 09/10/2023 - 09:56

    Careful when checking out that you don't get delivery by Romoss - they use Aramex.

          I deliver to a business address.

  • BrewerHaHa on 09/10/2023 - 10:50

    I've had one of these for a while. As others mentioned, it is quite large, it is quite heavy but I still like to use it. If I'm carrying a large backpack with something like my laptop or whatever I like to take it. If I'm using a smaller backpack or a tote, I will normally carry a 10k-20k powerbank instead. I've found it's really great when going on road trips but it does take a while to charge if fully depleted.

    I did go overseas with this powerbank, it was never checked, no one asked me about it, no one bothered reading the label, i managed to through a number of airports no problem so I don't think anyone cares that much. But you never know?

    • dav3 on 09/10/2023 - 11:06

      They might have toned it down a little these days (or their focus just switched since covid), last time I went overseas was around the exploding Galaxy Note period and even my small 10000mAh one got looked over a few times despite being well below the limit at the time.

  • MajorGaz on 09/10/2023 - 10:56

    Any suggestions on a 20k bank? Going to Fiji at the end of the month

  • hatxihoi on 09/10/2023 - 11:07

    anyone has an idea about the restriction on Qatar Airways ? Keen on buying

    • hatxihoi on 09/10/2023 - 11:09

      Just found myself: max 20k

    Bought one of these awhile ago. After a year and half noticed it wouldn't sit flat on the desk, turns out the battery was bulging and started to crack the case.

    Just keep an eye out… 30,000 mAh is a lot of battery to go pop.

    • bamzero on 09/10/2023 - 12:05

      Especially onboard a plane :0

  • LackingRuth on 09/10/2023 - 12:16

    Last purchased 7 Oct, 2020 for $35.20. Still going strong. Primarily used as a power source for my dash cam when parked as I'm too lazy to hard-wire. Have taken this on multiple overseas trips flying Qantas, Jetstar, Vietjet, Singapore Airlines and JAL. It has only been checked in Singapore with the bloke doing some quick maths then handing it back to me, however it is 111Wh so something to take note of. Also, it doubles as a weapon in a pinch.

  • SneedNFeed on 18/10/2023 - 16:26

    Not at this price anymore as of yesterday. It's ~$45

  • nuttapillar on 20/10/2023 - 10:16

    I got one of these probably 4 years ago, and it only seems to charge via the micro USB for some reason. And it's super slow. I left it charging all night, and it's not even half charged. Idk if it's degraded due to lack of use.
