AliExpress is having a huge sale day this coming 29th March.

10000mAh AU $22.60

16000mAh AU $33.22

20000mAh AU $42.53

These power banks are shipped to Australia from a large, trusted company.
AliExpress also has buyer protection similar to PayPal which I have personally used to get refunds.

Additional discounts are available using free vouchers within the store, though not considerably good.
Spend $46.55 and get $2.66 off
Spend $106.39 and get $3.99 off

Hope this helps someone out. Remember the prices are available on the 29th using the AliExpress App. It's worth the wait in my opinion!

    Seller doesn't seem to ship to Australia?

      Interesting.. I've purchased from them before so hopefully this gets changed!
      I've contacted them, will update once I hear back.

    Any USB C Power Banks?

    • voter1 on 24/03/2016 - 00:21

      the 20000mah one supports usb c charging (macbook)

  • Phreakuency on 23/03/2016 - 23:02

    I've never owned or even looked into these before but was just thinking about them today for my overseas trip.

    Is it true that the 20000mAh model can charge a phone up to 7 times?

      Is it true that the 20000mAh model can charge a phone up to 7 times?

      Allowing for a 15% conversion loss… You have 17,000 mAh of 5V power.

      The phone's conversion from 5V back down to 4.2V (charge) for the 3.7V lithium battery is also going to incur losses as well. Let's say 10% for that…

      So, 17,000 - 10 % = 15,300 mAh worth of charge. If your phone has a battery about 2000 mAh, then you'll get 7 charges.

      An iphone 6 has a 1810 mAh battery, so you might get 8 charges for that. These numbers are rubbery because there are variables involved.

      My son has an iPad Air 2 which has a 7300mAh battery in it. My 10000 mAh Xiaomi almost charged it once last weekend, and got bloody hot doing so. My power bank is getting old, and has done quite a lot of work, so it no longer stores 10000 mAh now days.

      I have the equipment here - I really should test it one day, and give a definitive answer.

      • voter1 on 24/03/2016 - 00:15

        one error is that the 20000mah isnt 5v power - its 3.7v power - they show the real 5v power in the fine print. (its 12700mah 5v)
        http://techcars.net/wp-content/uploads/2015/11/mo-pin-sac-du…
        xiaomi claims however 93% conversion rate
        so going by those numbers you get 6.5 charges from an iphone 6.

        they also write in the fine print that the above power numbers is from charging @ 1A
        if you charge at 2A - you should actually get less as well.
        I dont think you can select 1A charging on these xiaomi chargers so I dunno why they print this.

          they show the real 5v power in the fine print. (its 12700mah 5v)

          I had assumed 15% conversion loss from 3.7V to 5V, and thus 17,000 mAh at 5V

          xiaomi claims however 93% conversion rate

          I made a mistake because forgot to allow for the voltage change. However I also didn't allow it in the phone either, so it kind-of nulls out.

          Anyway 20,000mAh at 3.7V (Lithium) = 74,000 mWh

          These banks usually output a bit extra voltage to negate cable voltage drop…
          Convert to 5.2V output (74,000 / 5.2) = 13,461 mWh

          Claimed 93% efficiency, so (13,461 * 93%) = 12,519 mAh "at 5V"
          Which is close enough to what Xiaomi's fine print says (12,700).

          The phone is what dictates the charge current, not the power bank. Any (current model) iPhone will only charge at <1A, so the quoted figures are relevant. Many Android phones will charge at less than 1A (cheap/old ones pull under 500mA).

          Many modern Android phones have variable charging current. My Samsung Note 3 will pull maximum of 1.8A providing the voltage stays above 4.9 or so. Basically, as soon as it dips below 5V, the phones steps back the charging current it draws.

          On the small 200mm flat cables that I usually use, my Xiaomi 10,000 mAh cannot push enough volts at 1.8A so the phone always steps down to 1.2A when I charge it that way. I can only get 1.8A from the Xiaomi by using a Tronsmart or similar cable with bigger conductors (22AWG?) so the voltage at the phone's MicroUSB connector stays higher than 5V.

    i've got one that charges my iphone 6S 4 times. i used it all over india, it was so handy to have with me. Quality is very good

    Have a 10400 one and it hasn't skipped a beat. Good build quality.

    I think they champfer the edges now of the metal case so they don't scratch your goods as much.

    • llama on 23/03/2016 - 23:45

      Buy the silicone sleeve, much better

      • klownz on 24/03/2016 - 09:39

        Just grabbed one off ebay….

        Only $1 - should be ok I guess.

        • llama on 24/03/2016 - 10:27

          Yeah, it will be OK. I have a couple of genuine and a couple of fakes from BuyInCoins.

          The way that the sleeve fits is that there is a very narrow return lip that "folds over" onto the top and bottom surfaces ever so slightly. If the sleeve stretches over time this lip doesn't really grab properly, and it becomes annoying when you are handling the power bank.

          The fit and long-term tightness of the genuine sleeve are probably better, but for $1 who cares - if your cheapo one starts getting floppy you can always buy a better replacement.

          This sleeve issue doesn't matter much to me because I keep my powerbanks in semi-hard clamshell cases that came with some Wii control accessories or a generic "ipod accessory kit". These cases open by zipper and fold into 2 equal parts. There are 2 elastics that hold the powerbank in the bottom half, and a mesh section in the top half where I store various cables.

        • klownz on 24/03/2016 - 20:56

          @llama:

          Ah nice - that sounds like a 2.5" case that I have for portable HDD.

          I purchased from BuyInCoins too… hah! Hopefully all is good - like you said easily replaceable.

    i've started loading my shipping cart with stuff for the 29th.

    last night the site was showing the reduced prices for the 29th sale. but not now.

    I've got a nice watch lined up that is usually $35ish and down to $8.5ish

    • llama on 24/03/2016 - 10:06

      That is the correct procedure for a dedicated Ozbargainer.

      Beware of Time Zone differences… your well-laid plans will be destroyed if you miss the deadline!

  • munno on 24/03/2016 - 18:25

    it seems there are two kinds of 20000 mah batteries, one says original and another quick charge, not much difference in cost but not sure which one is better, anyone?
