      You can get approval to bring it in your hand carry.

      But why would you want that extra hassle. When flying around is a giant hassle already.

      Pro tip. Just bring 2x 20000mAh powerbanks. No hassle of having to get airline approval.

      With the added convenience of you swap around as you deplete one the other gets charged.

        Not always. It depends on the airline.

        Also, you are required to declare it as taking dangerous goods on board.

        • Point i was making is that its a hassle having to get approval. Flying anywhere is already one big hassle. Why add one more to it?

        • Just FYI these are above plane limits

          No airline under CASA regulation will disapprove a 101-160Wh battery that is in good condition, has the specifications printed on the battery, and is packed correctly. All of this applies to batteries <100Wh as well.

          The only difference between 101-160Wh batteries and <100Wh batteries is that 101-160Wh batteries may require declaration, either at check-in or beforehand.

          Overseas jurisdictions and airlines enforce lower limits, including no batteries at all, but these are largely coming into line with CASA/Australia's regulations thanks to the International Civil Aviation Organisation's April 2023 updated guidelines:

          a) each battery must be of a type which meets the requirements
          of each test in the UN Manual of Tests and Criteria, Part III,
          subsection 38.3;
          b) each battery must not exceed the following:
          — for lithium metal batteries, a lithium content of 2 grams; or
          — for lithium ion batteries, a Watt-hour rating of 100 Wh;
          c) each battery may exceed 100 Wh but not exceed 160 Wh rating for lithium ion with the approval of the operator;
          d) each battery may exceed 2 grams but not exceed 8 grams
          lithium content for lithium metal for portable medical electronic
          devices with the approval of the operator;

          ¯_(ツ)_/¯

          Pro tip. Just bring 2x 20000mAh powerbanks. No hassle of having to get airline approval.

          Agreed, especially for 30,000mAh when you could just get 27,000mAh and not need approval. 3,000mAh isn't worth the hassle.

          That being said, if you need 2x40,000mAh (like I do on large business trips), or you already own a >100Wh battery pack and don't want to purchase another, then the hassle is less than having to pass through CASA security already is. If you have checked baggage, then you pretty much just tell them when you drop off that checked baggage and the airline staff might ask to look at it - never happened to me and I fly about monthly.

          As Qantas has automated baggage drop off at some airports (e.g. T3 Sydney), you can just send them an email declaration and it's valid for 12 months. It's honestly just a formality. The only time a battery of mine has actually been inspected (and then also disapproved) was a 10,000mAh kmart battery with a crack in the case from being dropped. It was disapproved at the security check when my carry-on was being inspected, not by airline staff.

          Also, you are required to declare [a 100Wh battery] as taking dangerous goods on board.

          You were right in the first line when you said "It depends on the airline". We've been over this several times…

          The law is that you must have approval from the operator (airline) for lithium batteries 101-160Wh. Some airlines, like Air New Zealand and Air Asia, have blanket approval without the requirement to declare. Some airlines, such as Virgin, will approve these batteries at check-in. Jetstar and Qantas will provide a 12 month approval when you email them at [email protected].

          It is the discretion of CASA and operators whether to "reject all kinds of batteries which are neither in good condition nor well packed" regardless of size. All batteries are "dangerous goods", including in your phone, but not all dangerous goods are forbidden or require declaration. Hand sanitiser is a dangerous good… so are some torches.

      • Any suggestions for a 20000mah powerbank?

      • agree - for a small 15W output there really isn't much point to having a huge capacity. With two smaller powerbanks you also get more charging ports, redundancy if one breaks, etc.

    Rather wait for Romoss Powerbanks to go on sale, 30,000mah powerbank with 18/22.5w PD fast charge for around $35~

  • Chungus powerbank.

  • If I didnt have 2 Cygnett power banks already I'd buy this straight away. Very happy with all my Cygnett products.

    15W - that's disgusting and piss weak.

    • Have to agree. Thats pitiful. At least 35W or 45W even.
