  How does that compare to, say, this one from DSE (Kogan) for $23:

  I don't really know much about these or what makes one better than the other? I guess 45W will charge faster than 30W, but then DSE also has a 100W version for $77:

  Also, can I get the same (ish) thing, but with built in battery so I can also use it to charge on the go? If so, is that a good idea, or better to buy two separate things that each does what it does better?

    you have to check your device first, if it only supports 30W charging, even if you use a 100W charger, it still works in 30W. 100W is usually for a laptop, and it's much larger, it's actually not a technical question, just see how heavy you want to carry with you.

      The power pack that came with the laptop outputs 6A at 19.5V so call it 120W.

      I figured that as long as the charger can output the right voltage, it would just charge more slowly with a 30W charger than with a 120W charger (25% as fast I guess)?

      Weight is not really an issue from my perspective.

        Right. So if weight is not a problem, just get the highest spec.

          @cyphei: Thanks for your help so far…. :-)

          This appear to combine functions (140W and 27,000 mAh), and is $109 currently:

          https://www.dicksmith.co.nz/dn/buy/kogan-27000mah-140w-pd-po…

          If I was charging the laptop, which draws about 6A, then I am guessing that the 27,000 mAH (= 27 Ah) would presumably last around four hours (27 / 6 ~ 4.5) and it would be able to fully power the laptop since 140W > (6A x 19.5V).

          Am I getting that right?

          Is there any way to tell if it is 'okay' (compared to other brands)? To some degree, the price is good enough that I'm not too concerned, but figured I'd ask!

            @Alan6984: Batteries lose a LOT of their stored energy capacity to heat waste when charging your device. So you would get nowhere near 4 hours of charge time. And as the battery loses capacity over its lifespan, that time would only drop.

            For example, if your laptop had an internal 27 Ah battery and it was nearly dead when you plugged in the 27 Ah charger, you would not get a full charge of the battery (or anywhere near that).

              @guysaturday: Okay - makes sense.

              Windows reports that the battery has a maximum capacity of 54,891 mWh (not sure how accurate that will be but I'll go with it), so I never expected to get anything close to a full charge - this would be more of an emergency stop-gap until I could get to a proper power socket.

              Is there a rule of thumb about what percentage of the charger's 'rated' mAh gets turned into charge in the destination device?
