20% off with coupon box.

I was looking for a power bank and this one was recommended by someone in a comment on the forums (https://www.ozbargain.com.au/comment/12272103/redir). I have no experience with it myself.

Going for $27.99 at the moment (for the black) but also has a 20% off coupon bringing it down to $22.39.
The camels say this is the lowest historic price.

Blue and white also available, but they are both $29.99 with only a 10% off coupon so come in at $26.99.
You can only use the coupon on a single item, but it looks like you can use the coupon on all 3 (i.e. I think you could buy all of the black, blue, and white and use the coupon on each of them).

First deal, so let me know if I've got anything wrong.

      21 is a lucky number mate

    • HardQuiz on 24/02/2023 - 16:25

      To maintain them, do you discharge/recharge them at least once every few months?

      • johnmelb on 24/02/2023 - 16:35

        I thought it was best to store around 50% (not completely charged or discharged).

        • HardQuiz on 24/02/2023 - 16:38

          I’ll be honest, I don’t know what’s the best practice.

          I thought you had to do at least one cycle of discharge/recharge every 3 months.

        • Borg on 24/02/2023 - 17:26

          From memory, LiPo's out of the box are charged to 70%. Likewise when storing for a long period, try get them to around that. Just never store them away discharged long term otherwise they can drop below min and hard to recovery to full capacity.

      • hotphil on 24/02/2023 - 17:09

        Probably daisy-chains them and just charges the first one

        • xoom on 24/02/2023 - 17:10

          I plug one powerbank into another and i get infinite recharge. 🤣

    • xoom on 24/02/2023 - 16:25

      If you are asking. Then you do need it.

    • techno2000 on 24/02/2023 - 18:27

      I have a dozen and stopped buying them years ago.Will only buy once they die or become to old to be considered safe to charge/discharge.

    Does this have always on mode, or is there a similar one? Want to keep a USB lamp charged without pressing the button each time

  • eqbrains on 24/02/2023 - 16:54

    Rookie question. How do you get the 20% off? Is there a code?

    • captainslow on 24/02/2023 - 17:24

      Too late now, but for next time, there's a checkbox under the price to apply the coupon, as well as a link to the terms.

  • zanzibar on 24/02/2023 - 16:54

    Doesn't have a 20% coupon box for me. Also noticed the sneaky b@st@rds have jacked the RRP on this item compared to the white and blue one to make it look like a significant discount.

  • Brick50 on 24/02/2023 - 16:55

    Think they just removed it, not showing on app and can't tick coupon on website

  • povertytrap on 24/02/2023 - 16:57

    Price gone up and only 10% off now.

  • captainslow on 24/02/2023 - 17:02

    Yeah sorry everyone, that didn't last long. You can still get the blue and white at $26.99 with the 10% off coupon, but the black has gone up to $36.99 and no coupon.

    • kronk on 24/02/2023 - 17:11

      Think they've updated it as the blue and white both appear as $36.99 before coupon now

      • captainslow on 24/02/2023 - 17:20

        Thanks, so they have. Party's pretty much over now. That makes them $33.29 even after the coupon.

  • mmd on 25/02/2023 - 04:44

    Thanks OP,
    Looks like black one has 30% discount option now. Bought for $25.89

  • timmyd on 27/02/2023 - 11:42

    Is available again for $23.09 after a 30% coupon
