    Don’t really get why the last deal was so popular.

    Looks like a run of the mill battery.

    Glad people like it but.

          Lets be real. The cheapest way is rubbing sticks together (friction fire), then magnification, then matches and then a cigarette lighter lol. The battery doesn't even come close.

          I have both, but I prefer this one to INIU. It has a nice look, good quality, and solid build. It does fast charging for my S24 Ultra.

      • sam buster on 11/02/2025 - 08:42

        Why do you say that? Is this not a good product?

        • hsc21 on 11/02/2025 - 09:04

          I think someone posted that these are only 66% of rated capacity. So they're cutting corners somewhere.

          • sam buster on 11/02/2025 - 09:44

            @hsc21: Ah, thanks. I just saw on an Innui powerbank the seller claims all powerbanks are below the stated capacity…

            The actual capacity of power bank may vary from the rated one due to energy conversion (typically 85-92%) and circuit losses (typically remaining 65-74%). This is common for all power banks. *(Powerbank Rated Capacity × 90% × 74%)/Device Battery Capacity≈Number of Charges.

            So 66% might be lower than typical (got to confess I didn't find the above quoted info quite clear) but you would probably get enough to fully rechage your phone once, before the powerbank starts to diminish. Would seem to be ample for a quick top up, or for earbuds and watches.

            • parad0x on 11/02/2025 - 09:52

              @sam buster: DC-DC conversion is NOWHERE near as inefficient as this person is claiming… If it's not 95%+ it doesn't exist because it would be cheaper not to make it. I don't own a common model DC-DC converter that's not 95+ (I've about 6 models on hand).

              • superroach on 11/02/2025 - 09:56

                @parad0x: It's still true due to the step up voltage nature. These are 3.7v, stepping up to at least 5v.

                • parad0x on 11/02/2025 - 09:59

                  @superroach: Of course. So these are shoddy advertising? Cuz you can't take the installed capacity in mAh and apply it to 5v… That's why we should only use Wh to measure capacity

                  • Sqz66 on 11/02/2025 - 11:15

                    @parad0x: Most would agree this is dumb/deceptive marketing, but this has been the standard way these batteries have been advertised for as long as they've been around.

                    • parad0x on 11/02/2025 - 12:44

                      @Sqz66: Really? Even for a Cygnet or whatever from JB? That's a bit odd, but only when I look at it from the inside out, but outside in its no different to a wireless speaker with xxxxxmAh battery… Just a bit of a difference that the average consumer wouldn't distinguish between between and ramifications of LiIon/LiPo and LiFePo4.

                      Well, that was a strange realisation, I'll never look at power packs them same now lol

            • sam buster on 11/02/2025 - 10:07

              @sam buster: Correction:
              INIU not Innui!

              The quote is from the seller, INIU AU, on their Amazon webpage.

            • hsc21 on 11/02/2025 - 13:46

              @sam buster: 80 - 90% is normally what you'd expect. 66% is on the low side, but it was only a sample of one so ymmv.

              • sam buster on 11/02/2025 - 15:30

                @hsc21: Thanks. I appreciate the replies and info.

    • witheredcouch on 11/02/2025 - 09:15

      I got my partner one and she liked it because it is cheap, compact, and the flippable lightning cable attached to it means that we can have one powerbank with one cable that charges both out phones (the multi-headed cables always fail).

  • sam buster on 11/02/2025 - 08:49

    Has anyone tried these? It's a while since I bought a powerpack that could supposedly charge both Apple and Android devices, and had shared input/output ports (An Anker Slim model ~10 years ago).
    That was a disaster as it somehow started discharging my devices rather than recharging them!
    Following that my parents bought me a couple of cheap ones (from Aldi or Kmart. probably), but they would take several hours to charge devices, and then take all night themselves to be recharged. Not to mention their weight and bulkiness.

    • Dealr on 11/02/2025 - 09:12

      I have tried a good amount of power banks over the years. INIU has been terrific. Fast charge, great capacity, lightweight for most models.

      Edit: this 20000mah and the 10000mah models have been the best I've used. Highly highly recommended. https://amzn.asia/d/2SQvlaN

      Vrurc have been decent, previous models have taken longer to charge up, but feels like they hold capacity longer.

      Kmart and cheap consumer friendly models have always been horrendous in my experience.

      • sam buster on 11/02/2025 - 10:17

        Thanks, appreciate the reply and recommendation.
        After missing last night's Charmast deal, I had a look at INIU. I was tempted by the Slimmest model. Though I think it might be older tech now.

        I agree about cheap electronics, and generally avoid Kmart for such, hence I mentioned it was a gift, haha. It was actually Intempo brand for Target, but little better.
