    Thanks OP. Bought two. Hoping to just swap them out so I never have to wait. Cheers!

  • Sonca on 03/04/2019 - 22:32

    Good deal. Wondering why you guys need that much of capacity. The portable batteries are supposed to help you through the day only, why need up two 20k? I always have 2 packs of 10k swapping from day to day, but during one day, I never used up all the 10k.

  • coxymla on 03/04/2019 - 22:35

    Has anyone tried a device like this on a plane with a laptop?

    In theory you could plug the power bank into the seat USB, and plug the laptop into the power bank…

    • lostn on 03/04/2019 - 23:06

      The power output of the seat is usually poor and won't keep up.

      It doesn't even charge most of my devices when plugged in directly.

    • 4wd on 06/04/2019 - 01:18

      Not sure about other airlines, (I would think it's similar though), but Royal Brunei do not allow use of a power bank when the aircraft is in flight, either charging a device or being charged itself.

  • perplex on 03/04/2019 - 23:03

    anyone tested the actual battery size? from the phone it says it charges and how many times only adds up to bout 15000-16000, not 20,000

    • AssociatedClear @ Romoss AU Direct on 03/04/2019 - 23:18
      +2

      For all powerbanks their batteries are measured at 3.7V while the USB standard is at 5V for phones/tablets. So you need to do a conversion to get the capacity.

      3.7V x 20000mAh / 5V = 14800mAh

      • OpayuOnam on 04/04/2019 - 13:42

        Don't forget the conversion efficiency as well, for example Cygnett one is about 55% as I've tested.
        Xiaomi does really well, about 80% for high speed and 90% for low speed.

        • AssociatedClear @ Romoss AU Direct on 04/04/2019 - 15:25

          Yeah excluded the efficiency for simplicity. 85% on this power bank I'm fairly certain.

          • OpayuOnam on 04/04/2019 - 22:25

            @Clear: I'd say 85% is very high I doubt if it's the case for the Romoss given Xiaomi is 80% and their pretty much the best 👍🏼

  • cerealsmok3r on 03/04/2019 - 23:20

    How does this compare to the anker battery? I recall that one being just on the edge of being taken onboard of planes.

    • AssociatedClear @ Romoss AU Direct on 03/04/2019 - 23:24
      +1

      Without permission you can take up to 100Wh onboard with 27000mAh equalling 99.9Wh. This power bank is rated at 74Wh and you'd have no issue taking it onboard.

  • JHoliday on 03/04/2019 - 23:21

    How does it support Apple 2.4(A)?

    The specs say 2.1A?

      Blue port.

      • JHoliday on 03/04/2019 - 23:30

        Thanks, is the only difference between this model and the 10000mAh model the longer battery life? I was actually after a 10000mAh but since this is a good deal I might jump on it.

        Do you have much stock left?

        • AssociatedClear @ Romoss AU Direct on 03/04/2019 - 23:33

          Depends on which 10000mAh model as not all have fast charging tech like this. Sold 350+ with ~270 remaining.

    OP, noob question but what do they mean by "charging cable not included"? is that the cable we charge the power bank with? if it's, then how will we charge it then?

    • AssociatedClear @ Romoss AU Direct on 03/04/2019 - 23:57

      Yes no cable is included. You have the option of using a Micro USB, USB-C or Lightning cable that you may already have for recharging.

      • barozgain on 03/04/2019 - 23:59

    Can you bring powerbanks on the plane? Flying to HK in the coming weeks

    • barozgain on 04/04/2019 - 00:58
      +2

      yes Power banks should not be carried in your hold (checked) luggage, but it is fine to carry a maximum of two power banks in your hand (carry-on) luggage. Each must be individually packed and no greater than 100Wh, which is around 27,000mAh.
      Some airlines will allow you to take power banks up to 160Wh in your hand luggage, though anything over 100Wh must be approved by the airline. 160Wh is around 43,000mAh.

  • AdamFury on 04/04/2019 - 00:57

              I have two Sense 4s and they're still going strong, but I'd like to upgrade for USB-C PD for my Switch and iPad Pro.

              A quick question - this powerbank can be charged using USB-C PD and charging another device with USB-C PD from the same port. The iPad Pro can also apparently charge another device from its USB-C port. With this two-way capability, how do these devices work out which way to send power?

              • Zazer on 04/04/2019 - 10:13

                @lint: Also curious!

              • ozhunter68 on 04/04/2019 - 11:47

                @lint: See this comment for another usb C-PD powerbank below, there could be a similar function on the Romoss, a command to let device know it is about to receive charge/voltage via another usb c-PD charger.

                Good charger, but doesn’t output 60W for that long before stepping down as it drains. My other notes:

                Kogan 26800mAh 60W USB-PD battery
                - Only supports QC (>5V output) when one usb port is in use at a time
                - Supports total output of 18W via USB-A ports.
                - Supports USB-PD protocol charging via USB type-C port, up to 30W (20V, 1.5A)
                - Supports pass-through charging with boost e.g. 5V (12W) input, QC3.0 output of 9V (18W)
                - Does not support QC protocol input via USB type-C port (only 5V charging up to 12W, unless using USB-PD protocol)
                - Hold down the button to change charging direction - if connected to a supported device (e.g laptop).
                - Lights do not flash during charging if close to full.
                - If a device is using QC on one port, and it is unplugged, and then plugged into the other USB type-A socket, QC will be disabled on both ports. QC will not be enabled again until all ports are unplugged for a full 60 seconds. Until this happens, both ports are limited to 5V 2A (10W).

          Hi rep, mine arrived yesterday, charged to 80%. Have an issue with it though, how can I charge the power bank using the USB-C port?

          I'm not sure if I'm reading it wrong, but description says "Type-C Input: 5V/2A, 9V/2A", so I should be able to charge it using the same USB-C port, right?

          My laptop charges when I plug it in with a USB-C cable, but I can't figure out how to reverse the charging direction.

          And, when I plug the power bank into the mains, it does not charge or recognise a connection at all.

          I tried to change the direction by pressing the power button, then by holding it down, but pressing it seems to just change to show the charging speed, whilst holding seems to turn it off and on.

          Any solution? The manual did not have any instructions in it, just a few diagrams :/

    Got mine today, it was 0% charged. It has charged quickly to 70% and but has now slowed right down which may be normal. Main concern for me is the adaptor I am using to charge is very hot. It is samsung fast charge with genuine cable.

    • AssociatedClear @ Romoss AU Direct on 06/04/2019 - 18:33

      It's not unusual for a Samsung fast charger to run hot since it's using QC2.0 after all. Higher voltages means more heat.

        Ok cheers for that, it has charged from 0 to 70% in approx 2-3 hrs, now it's slowly worked it's way up to 90% in the last 2 hrs.

        Higher voltages means more heat.

        Higher V by itself doesn't produce more heat. Increase the power to get more heat.

          Higher voltage and less amps produces more heat than higher amps and less voltage in fast chargers.

          E.g. QC vs VOOC
