  • I bought this in the last deal and can vouch for quality.

  • This thing is huge and plasticy but works a treat

  • bought one last time and got rid of my old Mi power bank . This one is better with the display showing amp , volt etc which is very handy. The only difference with Mi power bank is that once you connect any device, you need to press the side button to charge. Otherwise it wont charge.

  • The pro 3 of Xiao no has 45w….seems m7ch bigger than this one? I don't even know what it means these numbers.

      That is also double the price so it depends on your needs. The Xiaomi 45W is more suitable if you're looking to charge say a Macbook while the Romoss is more than suitable for a USB-PD/QC 3.0 phone.

      • Cheers foe that. I'm using a Note 9. How about the imcompatibility? Still not fast charge 9 plus and Note 9?
        Last comment from last post give a really good and clear review.

  • https://www.ozbargain.com.au/node/457774

    Any experts can explain the differences between this one and the Xiaomi one?

    • +1 vote

      That Xiaomi has no USB-C ports which means it's no good for USB-C devices (most new phones, switch etc.) and won't have USB Power Delivery fast charging.

      • thanks mate (I got this one last time and can vouch for quality) but was looking to get a second one as a gift

      • The Xiaomi is also ~130g lighter than this one.

        The Xiaomi will charge 'new phones' - USB-A to USB-C cables work fine for QC3.0 for up to 18W (same as this charger). The only thing it won't do is PD - and at 18W it's really just Nintendo Switch (It won't charge a laptop).

        • +1 vote

          Yeah I didn't actually say anything about QC 3.0 and the heavier weight is due to the fact that the Romoss has more ports and the addition of USB-PD.

          At 18W it will charge laptops as was reported in the previous deal albeit slowly ;)

      • How about this compared to the ZMI Aura 20,000mAH?

        I'm looking for a 20,000mAH as light as possible.


      • Type-C Output: 5V/3A, 9V/2A, 12V/1.5A (18W USB-PD)
        Blue USB Output: 5V/3A, 9V/2A, 12V/1.5A (QC3.0

        Same Volt and current.


          Yes that's right. One is USB-C with USB-PD and the other is USB-A with QC3.0 (and others mentioned) so it's catering for both since they're not backwards compatible with each other.

    • The Xiaomi is not eligible for Amazon prime free delivery either.

  • One order with code per Amazon account

  • So these are good for charging the Nintendo Switch?

  • Is this device good to fast charge the s10 +

  • Just purchased one! Many thanks:)

    btw, which wall charger would you recommend to match this unit?

  • Anyone know if there are any smaller/lighter/lower_mAh ones (e.g. in the 4000 to 8000 mAh range) but which still do USB-C PD + USB-A (at least 5V/2.1A or more)?

  • Clear, any deal on desktop (5+ port) charger?

  • Did I have a Xiaomi 3 Pro? Yes
    Do I need another 20K power bank? No
    Did I buy another 20K power bank? Yes

    Thanks OP!

      Power banks are like eneloops. You can never have too many! My count is at least 20 now.

    • You will love this one to test out your charging performance/status readout, bit of geeky fun, but also useful too.

  • Any deal for the 10000mAh one?

  • I can't get free postage even spending over $49

    In stock.

    " Sorry, this item can't be delivered to your selected address. Learn more. You may either change the delivery address or delete the item from your order. "

    and even when I order 2 (which is more than $49 after discount) it still wants to charge me $4.99 delivery.

    I can get it delivered to say a Pharmacy 4 Less pickup point.

    It even states on the item description page:
    "Sold by Romoss AU Direct and Fulfilled by Amazon."


      I believe the issue is because it may be 1 per account. Try with a completely different product to see if that will change. I have Amazon Prime so I can't actually test that myself.

      • Why does it state "In stock.
        and then won't deliver to my address?

        The discount works on 2.


          Sorry I'm trying to troubleshoot the issue with you so we can work out what the actual problem is. Sometimes Amazon incorrectly says certain addresses are unavailable and their live chat need to fix it.

          Does it say it will deliver with just 1 in your cart? Will it deliver if you were to have 1 and then something else bringing the total over $49?

    • I can confirm if you buy 2, free delivery can be applied without Prime.
      You have to change the shipping method to "Free shipping". It defaulted to "Express shipping"

  • Is this any good for iPhones? I got Xs Max.

    • +1 vote

      Yeah it'll benefit from the USB-PD with a USB-C to Lightning Cable.

  • Does this do pass through charging? Can I use it as a UPS for my raspberry pi?

  • I'll give it a go….

  • Hi guys, what about pixel 3, could this fast change that?

  • Thanks Clear. Grabbed another!

  • Got one. $2 cashback bonus from Shopback sweetened the deal even further.

  • Ahh so good, thanks for putting this back on, for the features this price is unbeatable.

  • thanks op bought one! +1

  • and stackable with your favourite cashback provider.

    You sure about this? The coupon code does not appear on SB or CR.

  • Hi Associate,

    So it appears this will be OK to charge USB-C laptops in most cases? I really like all of the inputs, including the lightning port.
    What is the advantage of the 30,000mha model over this besides the additional charging? Will you drop the price on the 30,000mha model today?


      It's okay for most laptops depending on their spec, but ideally you'd want something with 30W or above. 30000mAh is just the increased storage capacity and there will be no discount today for that one. Need more stock to arrive first.

  • Does it rapidcharge pixel 2? The USB out is only type A, unsure so asking…

  • Are powerbanks the new Eneloops? I have six powerbanks in the house and read the specs on this one for a while before stopping myself and saying "WHAT ARE YOU DOING?". LOL

  • Anyone know where to get cheap usb c cables?

  • Be careful of this brand.
    There's several catching fire incident happened in China.
    The recent incident happened 13 April, a Romoss OM10 caught fire in an university student's bag.
    A tester disassembled Romoss power banks. There's no overheat protection in it like other brands.
    I'm not sure about this model. But I would never buy a Romoss.

  • How does this compare to the Xiaomi Power Bank 3 pro?

  • Just sent you an email in amazonau but I guess I can ask here, I thought all Romoss product come with a warranty/activation code to test if product is legit or not, but I dont see any code anywhere.


      I'm not a direct Romoss employee as such so I can't see anything sent through Amazon, but they have acknowledged your email and will reply.

  • Any USB-PD wall plugs that you recommend? Does this company make any?

  • I received it today.

    It came with 71% charge out of the box. I plugged in my 65W PD charger and left it charging for an hour. It still says 71%. What gives?

    Is the 65W PD charger considered too powerful and the power bank decided not to receive any charge from it?

  • received mine today, 75% charged out of the box.

    Charging via USB-C PD and getting 9V, 2A.

    having the screen is quite handy to see what the stats are

  • OP I ordered one but today I saw this:


    Any chance of a deal on the 30,000 mAh ?

  • Charging the power bank via official iPhone cable and charger, I get only between 0.5 and 0.9A FYI.
