    It doesn't actually support (~19V) laptop charging unfortunately.
    Looks like a good price for a jump starter though.

          That sometimes happens if you attempt to use Paypal Buyer Protection as a replacement for common sense.

          The solution is to screen your sellers better, and only buy from those who you'd trust.

          @cameldownunder:

          Then it won't matter if they block you from Buyer Protection, eh? LOL

          Anyway, it's exactly the same concept as your Car Insurance company warning you that they don't want your business any longer, after your 10th accident claim for the year.

          Paypal offers the Buyer Protection as a bonus service, and they make the rules. If you are making risky purchases, they deem it as "abuse". From my limited experience, I'd say that this will only occur if Paypal cop the refund, since the seller has vanished (so Paypal cannot claw back the payment).

          Whilst that happens all the time, if you are continually making Protection Claims then that would normally indicate that you were deliberately buying from shonks.

          what is the purpose in this case? To damage PayPal?
          The beauty of PayPal is that you can take some risks when buying stuff, giving you opportunity to buy from less reliable sources.
          I guess I had PayPal "coughing" up the money once, when the parcel got lost on transition.
          The rest of my disputes are resolved by me when the parcel arrives. The dispute helps the merchant to investigate the matter.
          The account that has been "warned" is the older one. In the mean time I have a second, almost "Virgin" account with PayPal.
          "aypal offers the Buyer Protection as a bonus service"
          I think that's the MAIN feature.
          Anyway, with all the future payment possibilities, and being now separated from EBAY, they better keep their customer happy.

    I'm told a car need at least 600A and in most cases 900A plus to jump start.. 200A is useless?!

    • cyssero on 17/09/2015 - 16:07
      +2

      My understanding and experience (having purchased a 300A jump starter) is that if you leave it connected to the battery it simply trickle charges it, it will be a bit slower with a lower CCA (cold-cranking amps) rated jump starter but it will work if you leave it for enough time.

      I've had a 300 CCA jump starter connected to a battery that wouldn't start a 4cyl engine and after waiting 5-10 minutes it started. That was a lead-acid battery so no idea how it will work with something like this and whether this is truly 200A peak output either.

      • Store Repgearbest @ GearBest on 18/09/2015 - 15:36

        Dear cyssero,

        It will happened like this when you choose the wrong capacity jump starter.

        Every car have its standard CCA. If it didn't match , It always have 2 results:
        1 The car jumpter output is much lower than the car standards , it will completely can not charge your car.

        2 If the output is just a little lower than the car standards, you need to wait few minutes to get the car started.

        We suggest that you need to check the car details again , make sure that you know the right capacity for you own car jump starter. You can search on the web with your own car model or contact your car seller to know the details .

    • blahbleh on 17/09/2015 - 17:09

      "In most cases 900A plus"?

      The vast majority of batteries can't even provide 800A, and the cheap 200A petrol station jumper cable was enough to jump-start my car immediately.

      That said, 200A won't start all cars, and certainly not in all conditions. This thing sounds better for partially drained cars or for letting the car battery itself charge enough for a single start.

    • ESEMCE on 17/09/2015 - 17:28

      Yesterday I bought a new battery for our Aussie V6 and it had 560 CCA on the label so, based on the assumption that;
      a) Aussie V6's need at least (if not more than) an average sized battery to start
      b) the label on the battery is not understating it's capacity
      then, what you've "been told" is so incorrect, it's not even funny.

      But agreed that 200 CCA is unlikely to start much…
      Maybe @cyssero has it, you need this and your half-dead battery to turn the engine over.

      • shaybisc on 17/09/2015 - 17:53

        How much did that cost?

        My father bought a jumpstarter + air compression- only specs I can see on it are 900AMP peak power and 400AMP "Booster Power". I used it on his 3.5l V6 on Saturday and it did nothing, not a peep.

    in the vid linked on GB page you can see where the black clamp sits when they have pulled it off the battery
    http://files.ozbargain.com.au/upload/72087/33543/bullshit_1.…

    then you can see when they go to start it the jumper clamp is back where the battery terminal is but the terminal is off screen now (imagine that…) use the red line of the handle in the middle of the battery to see what i mean. it appears that the terminal is indeed on the battery again thus motor is starting from the cars battery and not the jump pack.

      • NosDan on 17/09/2015 - 16:18

        yea, but that is sorta besides the point of this.

        this gadget is meant to be able to jump start a car without a car battery at all. meaning it should have enough amps to crank the motor over on its own but ive never quite believed that claim.

        fwiw connecting any jump starter (be it jump cables or a jump box) you are better off connecting the neg (black) to something metal on the actual motor its self (a large bolt or something is ideal) rather than to the battery or bodywork because the starter is earthed to the actual motor directly. means less power loss through the cars wiring system

      If your battery is only partially drained (e.g. left lights on while shopping), this should work. It can also charge up your battery enough to start the engine - just leave it connected for 10-20 minutes.

    • aussieprepper on 18/09/2015 - 17:52

      that is not enough to start v8s you need more amps!

  • geebee on 17/09/2015 - 17:52

    A lot of guessing going on here, I have a 300amp 6ah! (old SLA type) jump starter and it has easily started a 1 litre and a 1.3 litre engine both were dead to the point of no clicking even when the key was turned, hook up wait 1 or 2 minutes leave jump starter connected, both started easily.

    Not indicating the offered item is any good but as long as a plate hasn't snapped off the connecting post internally a low powered jump starter works well as you get the quick fresh charge in the car battery plus whatever amperage the jump starter is combined.

    • aussie216618 on 17/09/2015 - 19:26

      This thing is 80A with 200A at peak, not continuously outputing 200A.

      • geebee on 17/09/2015 - 21:37
        +1

        Yes, so it can dump a quick charge at upto 80 amps(never happen), and when left on to assist cranking can add 200amps short term peak to assist the battery which now has a partial charge.

        The pack I used would not maintain 300 amps for more than a second and I severely doubt it could hold 200 amps as it is only a 6 amp SLA.

  • tonyjzx on 17/09/2015 - 18:03

    You're really buying capacity. Think of it as a powerbank with the ability to jumpstart cars… rarely.

    I've only dealt with very bad situations where not even car to car jumpstarting doesnt work so these things? nah

  • Kevan2 on 17/09/2015 - 18:19

    Question from a novice. In trying to jump start modern cars with one or mor computers can the computers be stuffed?

    This may have been a urban myth started by the battery companies .

    Wish I had this for my old car ( 29 yo lite ace) today and yesterday - flat battery , left interior light and radio on, charged outside car on charger, and the had to replace + terminal . If it worked it would have been $9 cheaper to buy and let alone power and time wasted.

    • Russ on 17/09/2015 - 21:47

      As well as storing energy, your car battery also has a smoothing function. The power coming from your car's generator is usually anything but smooth, it was built with the expectation that a battery would always be attached.

      So if you have a loose battery lead, and it becomes detached while you are driving, then yes there is a significant danger of your car's electronics being damaged - both by the "lumpy" power from the generator, and also from a situation called "load dump", but a description of load dump would be a bit too long for this comment.

      If your car's battery has failed open-circuit, you may be able to jump-start it from another car, but as soon as you disconnect the jumper cables you are in the same situation as the "loose battery lead" as described above.

      So it's not an urban myth, but it may be rather overstated. Most jump starts are because of a flat battery, not a damaged battery. That said, I've heard that once the car has started, it's good practice to keep the jumper leads attached for five minutes before disconnecting them. It may be that a completely flat battery isn't as good at smoothing the power, so keeping the jumper leads attached permits the donor car's battery to aid the smoothing for those five minutes.

      • Kevan2 on 21/09/2015 - 14:13

        Thanks. It seems it pays to check every now and then outside services. Oh also do not leave lights or radio on if an older car.

  • Russ on 17/09/2015 - 21:56

    I think the figures are BS. "Persistent current 80A"??? So they say it can supply 80A at 12V, just under a kilowatt of power, persistently?

    Let's assume this battery is 90% efficient at supplying power at that rate (it won't be that high, but let's pretend). So it's putting out a kilowatt, and generating about 100 watts of heat.

    If you still have a 100W incandescent light bulb, I recommend you go and plug it in now, and hold onto the glass part when turning on the power. Feel how hot the globe gets, and how fast it gets hot. That's what will be happening to this battery if the "Persistent current 80A" claim is true.

    In reality it will be even worse, small batteries don't achieve 90% power efficiency when discharging at that sort of current.

    • terrys on 18/09/2015 - 08:07

      That's what I was thinking - the sight of the two great clamps leading into the connector looked as funny as monster cable would connecting a tranny earphone, but holding onto a small metal-cased battery that is cranking over a car is something that belongs in a road-runner cartoon.
      I was looking for the "ACME" label.

    • eug on 18/09/2015 - 10:36

      80A does sound exaggerated. It looks a bit undersized to have a 1KW boost converter that can run "persistently", although if the batteries run flat after 10 seconds, it could be possible if they had a large heatsink.

      100W of heat over a short time period won't be a problem with a properly-rated heatsink. I'm sure I could hold on to a 100W incandescent light bulb for a few seconds after first switching it on.

    • s732 on 18/09/2015 - 16:54

      Had a bit of a look into this. Apparently these things use Li-po batteries which have C-ratings (Capacity) of 10C to 40C. The C rating describes the rate with which the total capacity of the battery can be discharged.

      For example a 1000 mAh battery with a C-rating of 10C can ideally discharge at 10*1000 = 10000 mAh or 10 A. (http://rcfoamfighters.com/blog/?p=84)

      For an 8000 mAh (8 Ah) battery a 80A draw corresponds to 10C and a 200A draw corresponds to a 25C rating. These both seem reasonable as 35C and greater LiPo packs seem to commonly available.
      http://www.all-battery.com/highcrateli-polymer.aspx

      Though at 200 A the total capacity of the battery would be drained in 2.4 minutes! (Though probably would get quite warm)

      • eug on 18/09/2015 - 17:56
        +1

        The batteries are definitely no problem as large quadcopters can pull 40-80A. It's the boost converter which steps the battery voltage up to 13.8V (12V won't charge a 12V battery) that'll generate most of the heat.

        It's possible for a small pack to put out 80A, but I think the problem here is the word "persistent". :)

        • Russ on 19/09/2015 - 21:57
          +1

          I would be surprised if there was a boost converter in this device, one at that power level would be larger than the device.

          Thinking about the requirements for this, I think it probably contains four 2000mAh Lipo cells, connected in series. There is a step-up converter to charge the cells from USB, and a step-down converter for the powerbank function (easy to make a converter produce 5V at up to 2A). For the jump starter function, the cables will connect directly to the four cells in series. Although the voltage is a little high (4x3.7=14.8V), it wouldn't bother a car battery, and there will probably be a volt of drop in the cables anyway.

  • tanksinatra on 18/09/2015 - 17:04

    Don't waste your time. This '200A' jump starter only has a 'persistent current' of 80 Amps.
    The standard sized car battery in my 1.5L four cylinder Japanese hatchback has a 480 CCA rating - that means a sustained 480 Amps of current for thirty seconds at -18 degrees Celsius.

    This device might work as a portable trickle charger but only if you have a really really small battery. It only has an 8AH capacity - most car batteries will sit between 40 and 100AH.

          OK, I'd suggest adding a 19V output so it can recharge laptops too.

          pretty sure it does, 4 led's on the front of it show level?

        • RohBoat on 19/09/2015 - 18:38

          Suggestion is to have qualcomm QC charging.

          And the 19v output for laptop is also a good idea.

      Built in an array of flashing red LEDs so that it can be used on alerting the incoming traffic if the the driver and passengers are stranded at the side of the road?

      Looks like a very useful device. Small investment vs having to pay for roadside assistance.

      Providing a 18-19v power output socket would also add useful feature. Maybe including a 12v lighter socket output adapter would be a low cost feature addition?

          @nosdan:
          bummer, apart from slow shipping and the lack of communication (as per this thread), haven't had a problem with the dozen orders I've placed since FEB-2014

        • eug on 07/10/2015 - 23:17

          @nosdan: Now we'll never know who the winner is! :)

          @sebby: Same here. Either I've had no problems with my orders, or they took so long that I forgot about them. ;)
