      just a smidge over half a key bruz

    • Yea I carry mine and I'm backpack gets noticeably heavier.

  • I rather this than the 1.9kg one

  • good deal but i have enough power bank already

  • Picked up one from ebay couple weeks ago for 30.39 - they keep fluctuating the price so if you can wait and combine with 10%off ebay GC + CB might be worth it
    Otherwise - not a bad large powerbank!

  • I have two of these. Awesome powerbanks.

    • I have 4 joined in 2 pairs, yes they are very good. I checked capacity recently and they're still excellent after almost 2 years of use.

      • I have had one for a 2 years, but don't currently have the means to capacity test it. Out of interest how much use do yours see and what is their capacity sitting at after 2 years?

        • Mine are all showing around 90% of advertised Wh capacity @5v/2a. I use all of them most days to charge my iphone, ipad, airpods etc

    Note that you may have security at airport require you to register this as dangerous goods before every flight as it exceeds the limit

      Qantas/Jetstar will give you a form valid for 12 months of travel. With Virgin just declare it at check in ;)

  • Haven't these been tested to have a lower capacity than advertised?

    • Nope not at all. There was one guy who did a "teardown" and neglected to show that there were two 10,000mAh cells stacked together. Then there were others who discovered that battery capacities are different depending on what the voltage is. E.g. all power banks are rated at 3.7V, while phone capacities are 5V.

      • Gotcha. I've got 3 and the 1 I actually use has been great. Thanks for clarifying

    • If they have, link it up. Mine were all fine.
