    Any experience with these? Reviews look good.

    • yippy on 13/04/2021 - 20:07

      Bought a SW20+ and I must have been unlucky because it didn't even last 24hrs. Just died when I was charging my phone, screen went blank and all the ports stopped working. Returned it and got a refund from Amazon.

    • spinferno on 13/04/2021 - 21:23

      I bought the romoss 20,000 mAh model and my devices never quick charged from them

        You have to have a cable capable of quick charging. Also you must plug in to the 2nd USB PORT. One of the ports does NOT fast charge.

        Read his/her description. It's quite clear.

      I have the 30,000Mah since Aug last year.

      Works great and light for this size.

      • [Deactivated] on 13/04/2021 - 21:47

        Largest Battery in town for the cheapest $$$$. Personally I would go with Xiaomi Powerbanks if it's 20000mah.

        • pogichinoy on 14/04/2021 - 07:36

          And with that, the 45W Xiaomis that can charge laptops. I have one to charge a laptop when out camping.

        • TheChief on 14/04/2021 - 09:05

          My Xiaomi 20000mah Powerbank got swollen and cracked the case after less.6 months of usage.

        • mkowarkski on 14/04/2021 - 09:48

      I got a 5000 mah, which is the longest ever still living portable charger I have. It’s more than 6 yo. Used occasionally and still holds decent charge.

      I have used mine for -1-2 years now. Works well, fast charging works too.

      I find that the 20000 is enough for a plane trip ( shorter / longer) with two people. I mainly use it on the go when travelling for business.

    • Brightland on 14/04/2021 - 08:47

      I've got the SW20+, no complaints - it works and it's cheap. I don't need to drag it around with me so weight isn't an issue. I just use it to charge devices in the baby's room so I'm not running cables where the little bugger can get to them… the joys of a 1920's house and only one powerpoint in most rooms. Husband ended up buying one as well for when he travels for work.

    • superveggies on 14/04/2021 - 16:48

      I've had the 30,000mAh for about a year. It's pretty good. Well built, with plenty of ports, plastic but well assembled (no cheap feel). 10/10 would buy again if I needed one more.
      I always use it when I go out on holidays - can't depend anymore on finding power outlets at the right place to charge the phone.

  • DEvok on 13/04/2021 - 19:57

      SW20+, LT20PS+ and Ares do.

      Typically you want something 45W or higher. Unfortunately the 50W Romoss model won't be instock again for 2-3 months.

    • [Deactivated] on 13/04/2021 - 21:48

      Xiaomi 65W is the way to go for that…

    One of the ports on this doesn't fast charge. Makr sure the indicator is blue (indicating fast charge) and that your phone says it is fast charging!

    • superveggies on 14/04/2021 - 16:51

      The different ports have different symbols on top of them and charge at different rates.
      I have the 30,000 one and when I got it and noticed it, I actually cut a little table included in the quick user guide and glued it to the side of mine - so it's easy to tell what charge gives each slot

      • [Deactivated] on 14/04/2021 - 17:04

        Yeah kinda annoying. All the ports in the Xiaomi have fast charging.

  • archieduh on 13/04/2021 - 21:57

    Have 2 of theirs for 2 years which I can say are still working well.
    1 is a big one with fast charging.
    2nd is smaller more portable with inbuilt cable for usb and lightning adapter too. Hope they launch one similar to that one with inbuilt usb c. Sadly that design seems to no longer be available and not coming soon.

  • MasterScythe on 13/04/2021 - 23:43

    Anyone wondering what is worth buying? Honestly, unless you're a backpack carrier, a 10'000mah is the largest you want to go; the rest are just "too heavy" to go unnoticed in a satchel or a pocket.

    Personally, i own a rosmoss sw20+

    And this:
    10'000mah model

    https://www.amazon.com.au/dp/B017CUMANU/

    I almost never touch my rosmoss.

    Another consideration, is that LiIon are much more stable and abusable batteries than LiPo, in regards to safety.

    Ive had a couple of rosmoss "smoke out" at the 5 year mark (luckily, no fire, but the smoke is putrid).

    Personally, unless you NEED the bigger size, the battery choice alone is enough to sell me on something using 18650 batteries.

    Ymmv, just my experience and opinion :)

    • [Deactivated] on 14/04/2021 - 00:03

      That's concerning. Might stick to Xiaomi then. Have a Xiaomi Power Bank 2 a the 5 year mark and still works. It does make a hissing sound whilst charging though.

      • MasterScythe on 14/04/2021 - 01:35
        +2

        Thats capacitor or coil whine; not ideal, but not always a problem.

        As for smoking out, or fire risk; Its not a rosmoss problem; its any LiPo pack thats at risk.

        LiIon where possible if you're concerned :)

      • This Guy on 14/04/2021 - 06:21

        Xiaomi's can swell when short circuited (yay poorly designed major brand USB designs), which is very concerning when you realise what is happening and notice that it is in a metal case. Not sure what stops the reaction after the swell as I like my hands.

        • [Deactivated] on 14/04/2021 - 12:46
          +1

          Yup they do indeed swell/bloat. That happened to a Xiaomi Powerbank 10000mah 1st gen which I actually got a year or 2 after the Xiaomi Powerbank 2.

    • Lunchguy on 14/04/2021 - 07:29

      Bought the Rosmoss SW20+. Hope it does a decent job with my Galaxy Note 10

    • superveggies on 14/04/2021 - 17:06

      This is not something you want to carry on you all the time. It's more something you take camping (driving, not walking) and leave in your tent for a few days. Or charge once every 4-5 days and use it beside your bedside table if there are no power outlets nearby

  • Tehcookiemonsta on 13/04/2021 - 23:45

    Any of these support super fast charging for s21 Ultra?

    • ozhunter68 on 14/04/2021 - 14:37

      No. From memory their new 45W version did but unavailable for 2-3 months according to Clears comment on this post.

  • roofyapple on 14/04/2021 - 08:00

    I’m not sure which version to get. What capacity do I need to power my iPhone X, if 20000 mAh is good enough, what benefit do I get if I get the 30000 mAh instead? Would it charge faster or does it mean I can charge more times before recharging the power bank?

    Does 20000 mAh also need airline approval?

    • xoom on 14/04/2021 - 08:05

      what benefit do I get if I get the 30000 mAh instead? Would it charge faster or does it mean I can charge more times before recharging the power bank?

      30,000 will change that bit more. Not anymore faster than 20,000.

      Does 20000 mAh also need airline approval?

      20,000 no. 30,000 yes. It's why I rather travel with two 20,000 than a single 30,000. Don't have to bother getting approval from airlines.

      • DEvok on 14/04/2021 - 08:28

        Like the airline gonna care, the see oh power bank and will let it slip

          Or they could confiscate it because you didn't get approval. Your choice if you want to chance it.

    i bought a 10K one on the weekend (a few dollars more than this deal unfortunatly), came today. I have no experience with power banks prior to this and be happy to get a couple full charges from it (for when bushwalking). Look forward to putting it through its paces!

  • roofyapple on 14/04/2021 - 21:16

  • expatOz on 15/04/2021 - 06:05

    Whats the diff between sw20+ and sense 6+?

  • cornbeef on 15/04/2021 - 14:06

    Note the 18W fast charge 10,000mah LiPo Romoss Sense 4ps+ is also reduced by 20% when added to cart, from $29 to $23.20.

    • roofyapple on 15/04/2021 - 19:54

      How much quicker is the fast charge. Is looks a bit thick. Is it worth the extra couple of dollars?

      • cornbeef on 15/04/2021 - 20:20
        +1

        The world of power banks is a bit like how deep is the rabbit hole. These companies hardly make it simple nor are they consistent with information and models seem repetitive.
        All I know is it's a smaller format, pocket size, and half the size and weight that of the larger 20000mah units. This fast charge 10000mah unit provides the 18W of the larger units. The Sense 4 10000mah Clear listed in his post is less wattage and no LCD display, so it probably depends on the value you place on those features.
        There is a comparison chart between the units in this amazon link roofyapple. And you're right it does look chunky for a Lipo unit, closer to the size of a Lion unit with 18650 batteries as MasterScythe details.

      • RSmith on 17/04/2021 - 18:26

        The instructions that came with it said to do it.

        • AssociatedClear @ Romoss AU Direct on 17/04/2021 - 19:04

          I see. Feel free to just use it until flat then recharge.

          • MasterScythe on 19/04/2021 - 16:08

            @Clear: Yeah, you'll find literally every chinese made device has copy-paste nimh/nicd battery advice.

            Even a few entry level "big brand" devices do.

            Its actually something that should be looked into; but by who? Well thats the problem.
