    Which part of aus is this shipped from and what is he shipping time?

    Nvm.

    Might y this one cause my xiomni stopped working cause the port had been pushed in and there's no way to fix it.

  • MasterScythe on 28/12/2014 - 15:25

    10amps? 10amps at 5v? Thats a bloody ton of capacity

    • Maverick-au on 28/12/2014 - 16:01

      10400mAh at 3.7V and factor in the conversion rate (given in the specs) and you get the real mAh this unit can deliver.

      • eug on 28/12/2014 - 20:21
        +1

        The 85% figure is a bit misleading. It's easy to assume that you simply multiply 10.4Ah by 85% to get the real capacity.

        The capacity of the cells is 10.4Ah at 3.7V, which is 38.48Wh. But we need 5V, so the voltage is stepped up with a boost converter. That's where the efficiency figure comes in.

        At 100% efficiency, 38.48Wh is 7.696Ah at 5V.
        At 85% efficiency, it's 6.54Ah.

        So the true capacity at 5V is 6.54Ah, which is 62% of the stated 10.4Ah figure.

        Your phone also has some inefficiencies when charging. From memory my tablet is about 95% efficient when charging with it switched off. It'll be lower if it's running of course. So that makes the effective true capacity with that specific device 6.21Ah.

          eug, I'm 99% sure you are correct, so 6.15Ah
          ;)

          @battler: up

        • [Deactivated] on 29/12/2014 - 14:05

          Xiaomi's are rated at 90%, so ((10400-10%) * 3.7) / 5

          Edit: my assumption is these would be similar ratings.
          Your calculations look about right though, they're usually more around the 90% mark though

        • eug on 29/12/2014 - 15:17
          +1

          @dyl: The efficiency depends on the discharge current. I measured the Xiaomi 10400's efficiency and got 83.5% at 2A, 87.4% at 1.5A, and 91.4% at 1A. This one should be similar.

        • [Deactivated] on 29/12/2014 - 17:44

          @eug: Cheers for the numbers. What equipment is needed to test something like that if I may ask? I've used cheap equipment off eBay to test things like maximum output current, though it really doesn't show much other than that.. And that's on a good day when it even works.

        • eug on 29/12/2014 - 20:02

          @dyl: I used a CBA III battery analyser for that. You can also use a logging multimeter and programmable load.

    What's the difference between sailing4 (scorptec stock) and sense4?

    • blurrybird on 28/12/2014 - 17:12

      I want to know the same as this, but I think the Sailing 4 is a premium version with better efficiency and probably more safety features.

  • plague69 on 28/12/2014 - 16:28

    -This one better than XiaoMi 10400, can charge more
    -Input only 1A, slow charging, if empty, needs overnight

    • eug on 28/12/2014 - 20:09

      It should take about 12 hours at 1 amp. That's quite a while!

  • blurrybird on 28/12/2014 - 17:12

    Grabbed one because I had some spare paypal credit, pretty good for $9.14 :)

  • nedski on 28/12/2014 - 17:18

    bought one
    cheers OP

    main diff in Specs as follow
    Sense 4
    - Size(cm): L9 x W3 x H2.1
    - Weight(gm): 74
    - Input Current: DC 5V / 2.1A Max
    - Output Current: DC 5V / 1A, DC 5V / 2.1A

    Sailing 4
    - Size(cm): L13.8 x W6.1 x H2.1
    - Weight(gm): 256
    - Input Current: DC 5V / 1A Max
    - Output Current: DC 5V / 1A, DC 5V / 2.1A

    Also bought a Xiaomi 10400, will be interesting to compare the two

    • blurrybird on 28/12/2014 - 18:08

      That's a massive difference in size and weight.. are you sure that's comparing the same capacities?

      • edskii on 28/12/2014 - 18:53

        not sure buddy
        size looks ok but weight could be a typo
        got from their website

        • Maverick-au on 29/12/2014 - 19:07

          size looks ok but weight could be a typo

          One is nearly four times the size and so is the weight! One will be around 2500mAh and the other around 10000mAh capacity. Hardly a fair comparison.

    • Maverick-au on 29/12/2014 - 19:03

      main diff in Specs as follow

      Those specs are for totally different capacities! The Sailing 4 appears to be one with a quarter the capacity.

      The sailing models have better batteries (LG or Samsung), better electronics and a torch built in.

      Buy from a reputable online retailer.

      Think I would rather spend a bit more and get one from a retailer like HN etc

      So you would rather spend three to five times as much as you need to?

  • scynaz on 28/12/2014 - 19:25

    Have both Xiaomi and this.

    Pros for Xiaomi:

    • Looks better
    • much smaller in size
    • charges faster

    Cons:
    - one output

    Pros for Romoss:

    • two outputs, 2A and 1A

    Cons:
    - big and heavy

    Both are similar in terms of how many devices they can charge in normal use. No idea how they compare in terms of longevity.

      another pro for Romoss would be LED torch

  • DEvok on 29/12/2014 - 03:11

    Generally these Chinese banks are not that well, had my xiamon for only less than a month from a couple of charges, then the usb mini port for the charge was pushed all the way in making it unusable.

    • iridiumstem on 29/12/2014 - 03:15

      Are you sure that it's not a fake one?

      There are so many fake Xiaomi batteries out there, I even asked my girlfriend to get me one from China and she got a fake one for me which broke down without me even using it.

      I am not saying that yours can't be the real one because it broke down, but rather, fake ones break down so easily… Uggh

    • RedHab on 29/12/2014 - 10:03

      You probably had a fake. My Xiaomi is good quality.

  • daver on 29/12/2014 - 13:51

    http://www.romoss.com/proview.php?ID=17&pID=1 <- I think is the right model. No branded batteries explicitly mentioned and looks a shape similar to huawei y550.

    have $.42 yet to show up in cashrewards.

  • blurrybird on 05/01/2015 - 20:22

    So I received mine today, started charging it in a fast charging port and my Tikbro 4 Port USB Charging Station I received from here https://www.ozbargain.com.au/node/168366 decided to blow up.

    Beware. Overall the Romoss is legit, and very very high quality. I'd prefer one of these over my Anker but I haven't used any Ankers with the PowerIQ technology.

  • budgetgaming on 06/01/2015 - 13:12

    received mine today. seems good quality. currently charging. a lot heavier than i had anticipated :o

  • nedski on 08/01/2015 - 15:24

    Received mine a few days ago. Seems top quality and recharged my HTC One quite quickly. Looking forward to taking it overseas to keep my devices powered while travelling.
