Had some poweroutage in our place and wanted to keep my laptop up and running Cygnett 20000Mah power bank could not do the job , so decieded to go to JB Hi-fi and found this one on special, the guy who was selling was really surprised looking at the price $71 as it was down from $179.95 . Helped me run through the day. No complaints so far except it a bit heavy .
Enjoy
Happy ozbargaining

      Airlines measure battery capacity using watt hours. To get Wh rating: multiply the voltage (V) by the milli-amp hours (Ah), then divide this by 1000 to find your Wh.

      • MattBrisSyd on 18/12/2024 - 14:50

        How do you find out the voltage of power banks? All I usually see is max wattage and varying voltage:watt ratios per port

        • NuclearWessels on 18/12/2024 - 15:10
          +3

          You use the base voltage of the underlying cell- which pretty much for all of them being lithium is 3.7V

          3.7V * 45,000mAH = 166Wh.

          Such a weird choice for this power bank as if they just made it a bit smaller (43000 instead of 45000) then it would be ok for air travel with approval. Approval these days is just a declaration at check-in so quite manageable.

          • Inthemix on 18/12/2024 - 15:38

            @NuclearWessels: i believe you need to get approval prior to flying, well thats what i did last time as it may be confiscated at the security line

            • NuclearWessels on 18/12/2024 - 15:44

              @Inthemix: It depends on the airline - so you need to do some reading beforehand. Virigin for example is just declare at check-in. Each may have different rules

    If I break this open and divide the batteries into two, can I take this on a plane?

      I think you would be just under the limit yes

    • mrshorty on 18/12/2024 - 15:29

      why go through the hassle and risk being denied rather than just buying a smaller power bank

      • WowBargain on 18/12/2024 - 15:49

        What about if I split it into 4? Cheaper than buying and bringing 4 small ones on a plane

    • ConsumerAffairs on 18/12/2024 - 15:08

      At 30 cents kWh you'd need to charge it 1278 times to reclaim your cost

        Need to factor in charging efficiency losses

        • ConsumerAffairs on 18/12/2024 - 15:10

          Minus those, you could knock 10-15% off that figure

    Not good for international travel but this would be good for camping/local trips.

    • pronoun on 18/12/2024 - 15:14

      That's what I'm thinking. If we consider this for camping, what other "camping" type batteries would this compete with?

    • qube on 18/12/2024 - 15:15

      How good are these types of battery at holding charge eg fully charging it but not using it until 4-6 months later?

      • noshopping on 18/12/2024 - 15:17

        I have a few other brands and much smaller capacity I charged 6+ months ago and they're still on 95%

    • besttechadvisor on 18/12/2024 - 15:36

      or even domestic travel on planes.

      If you camp often, you'd get a lot more bang for your buck buying a 12V lithium battery from Kings.

  • noshopping on 18/12/2024 - 15:28

    is this right??
    One Ozito 4ah battery $69 - https://www.bunnings.com.au/ozito-pxc-18v-4-0ah-lithium-ion-…

    AI: A 4 Ah battery is equivalent to 4000 mAh.
    So this would be like bringing 11x ozito 4.0Ah batteries with you on a camping trip?

    • killingtime on 18/12/2024 - 15:30
      +3

      This is 3.7 volts that's 18

    • King Tightarse on 18/12/2024 - 15:32
      +3

      No you need to factor the voltage. Ozito batteries are 18v
      Wh is the way to compare

    • besttechadvisor on 18/12/2024 - 15:43
      +1

      V x Ah = Wh

      3.7 V x 45 Ah = 166 Wh in the Cygnett

      18 V x 4 Ah = 72 Wh in the Ozito

      As you mentioned, when using mAh, one simply needs to divide by 1,000.

      V x mAh / 1000 = Wh

      So this would be like bringing 11x ozito 4.0Ah batteries with you on a camping trip?

      166 / 72 = 2.3

      No, it would be like bringing 2.3 Ozito 4 Ah batteries, if we're purely discussing energy storage. You wouldn't be able to output 18V from the Cygnett to power your drill, though.

      • huubang on 18/12/2024 - 16:22

        How do I explain the charging time (for the powerbank itself)? So this has 166Wh and the powerbank is charging at 65W max. That means I should expect to fully charge it from 0 to 100% in 2.6 hours. But actual testing showed that I can only get 40% (from 60% to 100%) in 2 hours. What am I missing here?

        • besttechadvisor on 18/12/2024 - 16:33

          Charging isn't linear so I don't have a one-size-fits-all formula for you, unfortunately. It depends on heat, your battery's BMS, etc.

          If you're concerned that your charger isn't outputting the true wattage, you can get something like this:

          https://amzn.asia/d/hzTOAxU

          It's a worthwhile investment if you buy a lot of electronics online.

        • NuclearWessels on 18/12/2024 - 16:38

          2.6 hours is assuming perfect efficiency, which doesn't happen. Charging a battery also becomes more difficult as the percentage increases - the analogy is finding a park in a shopping centre - when it's empty it's very easy.. as it fills up it gets progressively harder.

    Thanks OP, I’ve been looking for something with decent capacity and this fits the bill nicely. Ordered.
