    Its a very expensive power bank @[email protected]

      It’s a very powerful power bank.

      • Nice looking too :)

    Damn, for that price I would have liked to see a higher capacity. 60,000 and I would loose my mind

    • A higher capacity would mean it can’t be taken onboard flights.

      • Ah Of course

      • Sorry if it’s a silly q, what’s the max capacity for flying?

        • +2

          Not a silly question.

          The max capacity is 100Wh. You will usually find the 'Wh' listed on the specs.

          If it's not listed and you know the mAh value and the voltage, you can calculate it yourself.

          Wh = (mAh / 1000) * volts

          In this case,

          27000/1000 * 3.7 = 99.9Wh

    How's this Aukey 30000 mAh different than the one you posted. Its much cheap and more mAh as well.

    • +2

      The Aukey only supplies 30W of power compared to 138W on the one posted. It will be slow charging devices that charge at a faster rate or may not even be able to charge them at all.

      It also takes 16 hours to recharge the Aukey compared to just 1 hour for the Zendure SuperTank.

      There are other reasons as well but the two mentioned above are quite significant.

      • Amazing what 30 seconds research can tell you.

    Nice! Requested to cancel my Cygnett order for this beast

    • Don't forget this one doesn't appear to have QC, whereas the Cygnett does.

      And you only need the 138W if charging multiple PD devices at once. Most devices charge fine at 60W.

      • The Cygnett only accepts 30W input. It will take around 3 hours to recharge compared to only 1 hour for this one which supports 100W input.

  • I’ve had my Cygnett for several years and the 60W output hasn’t let me down on my 15 or 16 inch MacBook Pros, if I was travelling like I did last year I’d have to give this a go.

    Also that recharge speed is seriously impressive. Way faster than the 30W on the Cygnett

    So I own this. Got it via Kickstarter.

    It's not bad for what it is though I have my doubts about its capacity. My laptop lasts around as long on this as it does on its internal battery. I had expected it to last longer as the laptop's battery holds far less charge (4k or 8k mAh - cannot remember). But then I may be misunderstanding something.

    It also plays havoc with the USB subsystem. It causes it to drop in and out and, eventually, fail. I noticed this as my BT mouse and touchpad used to start/stop before finally not working (they are connected via USB internally). This behaviour does not occur when using their normal, wall-plug, 100W charger. That's fine.

    This may be going on sale because they have a new model out (https://www.kickstarter.com/projects/zendure/supertank-pro-t...). This new one has upgradeable firmware which the one referenced in this deal does not.

    • (4k or 8k mAh - cannot remember). But then I may be misunderstanding something.

      You probably are, mAh capacity is not directly comparable when it comes to laptop batteries vs power bank. If your laptop comes with a 100w charger, I highly doubt this even has the capacity to fully charge your laptop even once (once you take into account conversion loss).

    My friend backed this via Kickstarter and it's junk. Two stopped working within a couple of months.

    ZMI recently announced a new 25000 mAh powerbank capable of 100w output via a single USB-C port which will supposedly retail for $60 USD in China from November. I'd wait for that.
