Ideal for charging laptops on the go

According to the site:
"The DC to AC car charging converter features compact and portable sockets with 110V output voltage. The 100W AC voltage (maximum output power of 120W lasting 5 minutes) charges any mobile devices such as laptops and tablet computers for extended battery performance and enhanced convenience during travel and business trips."

  I don't know the exact values, but can a car socket really output that much current safely? I mean, phones are one thing, but the description explicitly says "laptops"

    In this case, laptops with a 110v US charger

    unless you have a gaming laptop they dont really need that much power.

  Forgive the ignorance but are there any drawbacks to using this, i.e will using such a high watt charger be detrimental to a car? Also if the port can't output the wattage will the device self regulate or will you balls something up?

    The fuse will blow if the draw is too high. I believe a cigarette lighter draws 15amps so 180w would most likely be the max before the fuse will blow.

  110V output? So needs a laptop powe supply that’ll do 110V… I’m sure many do, but definitely not Aus Standard friendly

    It will require a US plug. Many laptop chargers are able to handle various voltages, but many are very close to the max draw for this device.

    I used to setup work utes with an inverter, for recharging tool batteries. Could be used for laptops (AU socket), but they were certainly larger than this!

      It has a universal socket, so you don't need a US plug.
      I think you'd be hard pressed to find a laptop charger which isn't dual voltage 110/230VAC.

    Pretty much all laptops will come with adaptors that auto switch between 110 and 220/240V, and no the plug on the end has nothing to do with it.

    Regular laptops will be sub-100W, higher-powered PC laptops can be 130W or more so would exceed the capabilities of this. A 16-inch MacBook Pro is 96W, all the other models are less.

    Does seem very small, though having an AC outlet in the car is very useful. I use the integrated one in my Ford Everest frequently.

  Looks like;

  output 230v AC @ max 100W surge 120W

  …The description in the specs is really poor.

  Using one of these will waste a lot of energy and kill your battery really quick. There are huge losses when inverting from low voltage DC to high voltage AC then back again.

  There are better ways to charge a laptop from a car battery. You can buy consumer grade DC-DC inverters that will give you 19v or whatever you need, from Jaycar, Altronics, eBay, Amazon etc.

  Or you can buy an adjustable inverter for like $12 and make leads if you know what you're doing. I bought a bunch a couple of years ago. I use one to power/charge my JBL speaker that requires 19v. I uesd another to supply 36v to a tool battery charger. They have a led segment display that tells you exact voltage. Unlike inverters they have very low idle current and conversation losses.

  Similar to what I bought…

  Heaps of options.
