    Looks like better value than what Bunnings has for $100

        That one has 172Wh capacity with 200W AC output while this is 300Wh capacity with 300W AC output. I'd consider those two features alone to be worth the extra $99.

        Edit: 300W continuous, 600W max output and not 500W apparently.

          I wouldn't be so sure… the bunnings power station is half the price of this one so on a $/kWH the bunnings is better value.
          Also the bunnings one supports bi-directional 100W USB-C PD which mean it'll run fairly beefy laptops without an AC adapter. This one only has 36W USB-C.

          • Clear on 27/05/2024 - 22:39

            @tanksinatra: Would have made more sense before when I said it was 500W/1000W and not now. AC output is where it matters to me - for USB-C I'll just use my own chargers. Better, faster and reliable.

              @Clear: @Clear Sure but running DC->AC->DC is going to be a lot less efficient than DC->DC.

    • iDroid on 27/05/2024 - 19:54

      • seamonkey on 27/05/2024 - 21:56

        Genuine question..What's the value in this scenario? I'm clueless about the product but I assume if you have an unexpected power out, you'll likely lose what you were working on regardless. How does then plugging everything into this and getting 2 hours make the difference? Is the big picture that you'd hopefully be expecting the power to be up again in 2 hours? I kind of have always wanted one but I can't come up with a personal scenario yet whereby I'd benefit. Is there something I haven't considered?

      • athk on 27/05/2024 - 20:19

        Thank you, I don’t think I’ve ever heard the fans spin on this thing during work so I think it’ll be fine. Just thought I’d ask before pulling the trigger.

    • Prong on 27/05/2024 - 22:05
      +2

      After efficiency losses (in the power station, and the device being charged) you can expect around 200Wh to be added the the battery of the device being charged.

      So check how many Wh your particular MacBook battery is, then divide 200 by that number. EG, 70Wh battery will get around 2.85 charges.

  • Unrvl on 27/05/2024 - 20:06

    Save your money, these are total garbage. I went through a couple and Jaycar were nice enough to change them over when they stopped working, but the best thing they let me do was pay the difference to go to a Bluetti. I cannot even begin to explain the difference between the two, totally different class of build quality in the products.

    • athk on 27/05/2024 - 21:43

      Curious what issues you were having?

      • lansalot on 28/05/2024 - 09:06
        +11

        The inverter wouldn't work after a while. This happened a couple of times on different units.

        On top of that the fans are loud in these things and i suspect they are prone to overheating. I don't believe that they are actually pure sine wave either.

        Power conversion is extremely inefficient too, a 268wh Bluetti EB3A will last much longer because the inverter is much more efficient. Remember these have to convert voltage no matter how you use them, 240v, 12v, 5v (the 12v may actually be pass through from the 14.8v battery, but it still didn't last as long as the Bluetti when i used it in 12v setup either).

        Save the hassle if you are getting this just to run 12v and get your own battery plus a Victron Smartsolar 75/15, the quality and battery monitoring on the Victron are incomparable.

        If you must have a portable power station with 240v too then go the Bluetti. Jaycar price match brick and mortar stores and stock Bluetti.

        I've owned this powertech plus the 500wh unit they've discontinued, I no longer have either of them. I've also had and returned a couple of Ecoflow units (river, river 2 pro). I currently have a Bluetti EB3A, Bluetti EB70, and an Allpowers R600. The Allpowers is the quietest of them all, but nothing I've used comes close to the quality of the Bluetti. My 12v setup has a Victron Smartsolar 75/15 and the bluetooth app let's you monitor charge and power levels, though I've put a Renogy shunt on this to monitor my battery, which is a cheap 100AH Kings Lithium that's done the job. Spend the extra $$$ on quality brands, or spend $199 on this powertech unit to learn that lesson (if you return it within 30 days as per jaycar policy then the lesson is free, that's what i was lucky enough to do).

        • athk on 28/05/2024 - 09:40

          Thanks for the insight, the BLUETTI AC2A is only $399 on two sites and the BLUETTI EB3A is $418. I'll see if JayCar can match one of those and try it out.

          100% Right on the spend a bit more, especially with batteries and inverters.

        These basic units will not charge and output power at the same time. E.g. if you have solar connected to charge it, all outputs will be disabled.

        Bluetti ones have full passthrough. So you can charge and discharge at the same time.

    • bcYield on 27/05/2024 - 23:01

      Can tell from the look of them in comparison but the Bluetti deal has never been back since while currently is double the price of this one without bonus sola planel.

  • gtech on 27/05/2024 - 23:00

    Have a similar spec one. These are good for low power use devices sub 300w. Great for a short 4wd trip (day) and maybe a weekend adventure if you can recharge them (ie solar or car). Even with low power devices ie small fridge, led lights and phone you have to play "power station manager" to ensure that the you don't run out. But if you are looking at buying an real system (ie blueetti or ecoflow 1000wh++) this is a good stepping stone to give you an idea of how much stored and output power you really need.

    Which is better, lithium-ion or LiFePO4?
    0:20
    LiFePO4 vs Lithium Ion Batteries | An In-Depth Comparison …
    LiFePO4 batteries offer a longer lifespan than lithium ion batteries, with the ability to last up to 10 years in the right conditions. On the other hand, lithium ion batteries typically last around 2-3 years. This is due to the chemistry and materials used in their construction.

  • hrjf on 28/05/2024 - 06:29

    Would this do for a simple camping setup? For something like a couple led strips, a smallish fridge, phone charging type of stuff?

    • AmperSand on 28/05/2024 - 06:46

      Something like this would have like 3x the capacity if it’s just used for 12v stuff and nearly the same price. You would need a means of charging it though

      • bargainshooter on 28/05/2024 - 07:14

        More like 2x capacity given they can't be discharged past 50%. Benefit is you can use whilst charging.

        • AmperSand on 28/05/2024 - 08:04

          Given the cells in the 300wh power station are li-ion and only rated for 800cycles (as stated in the provided manual) 100% DoD will certainly reduce the lifespan of it. That rating is likely at 80% DoD. So taking that into consideration is why I said roughly 3x capacity.

          Also will be limited to 12v 10a discharge on the power station. So running fridge, lights etc (depending on how many) will be a stretch unless the lights are all USB powered or 240v is in use (which will make the runtime abysmal).

          I just don't really see this thing being fit for purpose for the question being asked. Maybe I am wrong, but if it were me I'd be taking the AGM if it was my sole purpose for usage.

              I have a 100a AGM and 120a lifepo4 so I know the weight differences. I was just using same store similar price.
              I wouldn't expect a no-name brand lifepo4 from ebay to last very long.
