    Just make sure it can do 20V output off a 12V input, many can only do it off a 24V input.

    • +3

      It doesn’t seem to specify… begs the question if it has a DC voltage boost

    • It would be 20V output off 12V input. Just like any 12V universal laptop charger

      • +2

        Why do you make that assumption? Most USB chargers like this can't boost the voltage.
        I'd err on the side of caution, but that's just me.

        • The package looks too small to contain a boost up as well… ¯_(ツ)_/¯

          • @mitchins: A boost up can fit on a 2x1cm pcb board…

            • +1

              @ATangk: A 100W one might be a little larger, but yes, they're pretty small and the size alone is not enough to discount it.
              But if I made a USB charger like this, I'd ensure that people knew it could do a 20V output using a 12V input.

              • @spludgey: It says 20V5A in the list of outputs. Is that not saying that it can do 20V output?

                • +1

                  @ATangk: Lots of them say that and then hope that people don't complain and if they do, they say that this is only for a 24V (trucks, etc) input.
                  I own a small lithium battery company that uses USB sockets in the side of the battery that can put out 20V on a 12V input, but it was a real pain finding one.

  • Does anyone know if it will do 25w Samsung Super Fast Charging?

    • +1

      Yes it does. Samsung requires PPS and this does it.

  • 118W? Geez, poor car batteries.

      If you're a healthcare worker make sure you get the free AAMI roadside assistance. it'll be a good combo!

      Poor cig lighter circuit… 10A would be the max for most lighter circuits and this would draw at least 10A/12V at max capacity

      • All my VW’s have been 20A

      • +1

        Wouldn't it be just under 9A at 118W? Should be fine at its max draw. Just have to be careful with other devices you've got plugged in to the same circuit.

        • 118 / 12 = 9.8A With losses, it could easily exceed 10A.

        • +3

          118W / 12V = 9.87A. That said, batteries will hover around 14V while the car is running and the alternator is engaged, which would only require 8.4A, assuming the device is 100% efficient.

      118W is bugger all. The average audio amplifier is 400-600W

      • +4

        They're not generally run off cigarette lighter sockets.
        Also, I'd take audio power ratings with more than a grain of salt. RMS does not mean what they seem to think it means.

        • Most cars these days are dedicated 12V power outlets, not cigarette lighters

          • +1

            @antik: I'll play your game, you don't generally run amps off automobile auxiliary power outlets (the official name).

  • I don't think road assistance will cover a new battery. They will help you to jumpstart and next thing your car breaks again.

      A true OzBargainer has already several GOOLOO and GREPRO jump starters! :-)

    The Output for the USB goes up to: 15V/3A and 20V/5A, does it work for the voltage/amps in between? Eg 18V/4A?

    • I'd like to say yes but without actually having one to test I'm really not sure.

    • +1

      No, the device will communicate with the charger and set one of those voltage levels. Current is variable though.

      • Gotcha, so 20V/4A is totally possible?

        • +2

          As long as it can actually do voltages over 12V with a 12V input (read the first post above), yes absolutely!

  • anyone know if it works with macbook airs? know they can be fussy

    • They have a MacBook in the marketing image so you would assume so.

  • -1

    Some1 buy it and report back if it does do 118w with proof via a vid. I call BS.

  • Anyone know of something like this powerful but with a FM transmitter?

    • When the device is charging that annoying whirring sound is unbearable… In my old cars with no bluetooth I always made sure to keep the charger and the fm transmitter as separate devices to reduce this…

  • Banggood is scambags, took a deposit for one of the deals, never communicated back to pay the rest and now saying sale is ended and deposit is not refundable. Avoid.

      Did you PayPal dispute?

      • just have done it

  • Not sure how reliable this answer is, but in the Q&A someone said it does 100w from 12v.

    Q:Can this output 20V 5A from a 12V car battery source
    A:Yes it can through the type-c output

    From comments here it was sounding unlikely, but can anyone who has received this confirm it for this model?

  • My aux port says 120w max 12v. How long does delivery take?

  • Arrived today, so it's 100w max on the USB-C and 18w on USB-A. Seems to charge my Lenovo X1 via the USB-C.
