      Yes please

    • comphelp on 15/07/2019 - 20:47

      Me too.

      Also, wasn't a 26,800mAh coming too?

        There are plans but nothing yet.

      I'll put it to Romoss and see. Possibly as the next deal.

      • [Deactivated] on 15/07/2019 - 21:37

        Will that deal run concurrent to this? I don't want to miss this if the bigger one doesn't go on special.

          Yes it will. Takes about 4 hours for Amazon to approve coupons so I'll have it early tomorrow morning.

          • [Deactivated] on 15/07/2019 - 22:01

            @Clear: Fantastic, thanks!

    This brand sucks. Mine lasted about six months and the capacity dropped to less than a phone charge. Same Xiaomi one is still working fine. I am sure they use dodgy batteries inside.

    • AssociatedClear @ Romoss AU Direct on 15/07/2019 - 20:45

      Which power bank was it? I know last time you mentioned it was a 10000mAh variant and not the one in the post.

      • flash659 on 15/07/2019 - 20:57

        I own both a Xiaomi and Romoss (bought both at the same time) and neither has ever missed a beat.

    • bananabendera on 15/07/2019 - 20:56

      Nah I bought a 20000mAh Romoss power bank about 2.5 years ago. I have left it for many a time on 100% or 0% for weeks at a time, and there has been a crack on the LCD plastic screen for about a year now. It still has about half capacity left. I would absolutely recommend Romoss.

    • confidantduk on 15/07/2019 - 21:47

      Dude, my 10kmah I boguht 4 years ago still has roughly 3/4 capacity and still chugs like a beast, think you got a lemon. They've got at least a year or two of warranty too.

  • Zazer on 15/07/2019 - 20:54

    What I like to see! Another deal on these. Got one last time for $27.99, excellent power bank! Will buy again if I need another :)

  • kml22 on 15/07/2019 - 20:56

    This battery pack is the best, hands down.

  • Tutien87 on 15/07/2019 - 21:01

    Got one last time. For the price its totally worth it

  • impoze on 15/07/2019 - 21:03

    Great power bank, have this as well as the Xiaomi one, the display is really handy

  • randomgbvfdcer on 15/07/2019 - 21:04

    So it can't fast charge a s9+?

    • AssociatedClear @ Romoss AU Direct on 15/07/2019 - 21:10

      Afraid not sorry. The implementation of QC was changed in the S9 and not compatible with the chip used in this power bank.

      • kev go westie on 15/07/2019 - 21:40

        cant fast charge a S10 as well? whats the difference between fast and regular charge? also whats the difference between the two 20000mah other than size?

        • AssociatedClear @ Romoss AU Direct on 15/07/2019 - 21:46

          Basically anything above the S9 so the S10 is included.

          Fast charge is at the following volts/amps: 5V/3A, 9V/2A, 12V/1.5A while regular charging is up to 5V/2.1A. The other 20000mAh only does regular charging.

          • Bargain Fighter on 15/07/2019 - 22:16

            @Clear: Does this also mean no fast charge for Note9?

            My Romoss Sense X can fast charge Note9.

            • AssociatedClear @ Romoss AU Direct on 15/07/2019 - 22:18

              @Bargain Fighter: According to Romoss. I have not tested myself personally.

          • kev go westie on 15/07/2019 - 22:17

            @Clear: so the regular size 20000mah has fast charging for some phones whereas the mini has just regular charging. is this correct?

  • tivo on 15/07/2019 - 21:28

    Will this fast charge an iPhone 10/10r/10s using an MFI certified USB C to lightning cable?

    • AssociatedClear @ Romoss AU Direct on 15/07/2019 - 21:28

      Yes as it supports 18W USB-PD.

  • suchan on 15/07/2019 - 21:49

    Looks great, will I be able to charge my Macbook Pro with it like the Xiaomi Pro 3? If so, which model should I go for?

    • AssociatedClear @ Romoss AU Direct on 15/07/2019 - 21:50

      It can charge a Macbook Pro but is limited to 18W making it less ideal than the Xiaomi that does 45W. The SW20 in this deal is the fastest of the power banks.

  • AssociatedClear @ Romoss AU Direct on 15/07/2019 - 21:53

    Will have the 30000mAh variant added tomorrow.

  • rodriguesssss on 15/07/2019 - 21:58

    could someone explain the difference between the 4 models,
    obviously twice the capacity for the first 2 , but whats the diff between the first 2 and the second 2

    • AssociatedClear @ Romoss AU Direct on 15/07/2019 - 22:02
      +1

      The first model (SW20) has the fast charging in it, while the remainder have regular charging up to 5V/2.1A with different types of ports and capacities.

  • rodriguesssss on 15/07/2019 - 21:59

    will quick charging work on a oneplus 6t?

    • AssociatedClear @ Romoss AU Direct on 15/07/2019 - 22:01
      +2

      Afraid not sorry. The OnePlus 6T requires a power bank with Dash Charge (5V/4A) and there aren't many power banks out there that do.

  • petry on 15/07/2019 - 22:00

    cheaper at banggood etc in the past…

    • AssociatedClear @ Romoss AU Direct on 15/07/2019 - 22:04

      Banggood have not stocked the SW20 let alone Romoss for a very long time. Besides this is local stock!

      • petry on 15/07/2019 - 22:09

        define long - 3 years as above - 4 years as above etc etc or a piece of string…

  • Maloo on 15/07/2019 - 22:41

    So the ROMOSS 18V 30000mAh does have the fast charge for iphone or not? The above comments are conflicting to the item description.

    • AssociatedClear @ Romoss AU Direct on 15/07/2019 - 22:42
      +1

      The 30000mAh supports it via USB-PD. Like all fast charging for iPhone you will need a USB-C to Lightning cable.

      Type-C Output: 5V/3A, 9V/2A, 12V/1.5A

      • Owgasm on 18/07/2019 - 23:32

        The SW20 didn’t have fast charge for iPhone?

        • AssociatedClear @ Romoss AU Direct on 18/07/2019 - 23:32

          SW20 Pro in this post does. The USB-C port is USB-PD.

          • Owgasm on 18/07/2019 - 23:36

            @Clear: Ah sweet. Now to find a usb-c to lightning cable

  • XeKToReX on 15/07/2019 - 22:45

    Hmm, too bad none do 45W USB-PD.. might have to get the Lenovo one and have work shout it..

  • brad900 on 15/07/2019 - 22:50

    I have no idea of the difference between these models, can someone please advise which is the best value

    • AssociatedClear @ Romoss AU Direct on 15/07/2019 - 23:02

      Covered that here. Basically the SW20 Pro in the main link and the 30000mAh coming later are both the fast charging power banks.

      The remainder are regular charging power banks and why I didn't specifically talk about them in the post.

  • mh0408 on 15/07/2019 - 23:23

    Does anyone else's bank take forever to recharge? I have the 18W Power Bank (20,000) and as of right now, it's been charging for over 24 hours on a 10W wall charger and it's only at 43% (from 0%). Doesn't seem right…

    • AssociatedClear @ Romoss AU Direct on 15/07/2019 - 23:25

      That doesn't seem right at all. Do you have another charger you can test it with?

    • lostn on 16/07/2019 - 09:18

      The charger matters.

      I got a 65W PD Dell dock and it doesn't even charge the thing at all. It doesn't accept the range of V/A the 65W PD is outputting. I switch to a 18W charger and it does charge.

      But not as slow as yours. But then you are using 10W.

  • djprima on 16/07/2019 - 00:12

    Got one, thanks OP! Was eyeing the xiaomi one but looks like this is good enough

  • muchape on 16/07/2019 - 02:14

    Nice i got the 30k one cheers

  • [Deactivated] on 16/07/2019 - 07:20

    Does the SW20 fast charge mate 20?

    What's the airplane restriction on powerbank, I heard anything above 21000.

    • AssociatedClear @ Romoss AU Direct on 16/07/2019 - 07:33

      Unfortunately it won't fast charge the Mate 20 as that requires Huawei SCP.

      Without permission from the airline the limit is 100Wh and anything above up to 150Wh requires permission.

      The formula of working out the Wh is (mAh)/1000 x (V) = (Wh)

      So 21000/1000 X 3.7 = 77.7Wh

    • Caped Baldy on 16/07/2019 - 09:21

      From memory around 26000mah is the limit

  • lostn on 16/07/2019 - 09:15

    Does the C port on the Romoss LT20mini also double as an output or input only? If it's output, what's the maximum watts?

    • AssociatedClear @ Romoss AU Direct on 16/07/2019 - 09:19

      Input only, 5V/2.1A. I recommend the SW20 Pro or Sense 8+.

  • Gordon84 on 16/07/2019 - 11:48

    Any 30000 mAh banks left?

    • AssociatedClear @ Romoss AU Direct on 16/07/2019 - 13:24

      All sold out sorry.

  • Xianese on 16/07/2019 - 12:16

    What would be the best choice if I'm simply looking for something to use as a travel phone charger, while out and about?
    (And potentially a Switch charge or two….)

  • Owgasm on 18/07/2019 - 23:29

    I just received my SW20, it’s huge and clunky.
    Hope the plastic holds up.

    No charging cable supplied interestingly enough.

    Straight out of the box my display has fine scratches throughout the screen. Pretty poor form.
    -Anyone else had this problem?

    • naisuda on 19/07/2019 - 20:23

      This might be a dumb question, but did you take the screen protector off?

      • Owgasm on 20/07/2019 - 00:07

        Did yours come with one? Mine didn’t.. I think that’s the issue

        • naisuda on 20/07/2019 - 07:20

          Ah, yes mine did come with a small circle piece of plastic covering the screen.

  • jakeyo on 20/07/2019 - 19:29

    Just bought the SW20, seems like good value!
    I needed a battery pack with a larger capacity - my 4400 cygnett isn’t enough

  • jrad0 on 25/07/2019 - 14:24

    Hey OP I just missed this, any chance of it going on sale again? Cheers

    • AssociatedClear @ Romoss AU Direct on 25/07/2019 - 20:09

      Definitely. Just waiting on getting more stock in.
