Brilliant bit of kit
Needed this so I could keep working g the car on a drive up to Scotland. Worked brilliantly with my laptop. Its not powerful enough to charge it much but at the very least kept the battery level at 90% all the way through the trip. Even handled a 30 min video call without any power lose. The built in USB we used to charge my wife's phone while she was using Google maps, which actually charge the phone to full from 50% in an hour. Honestly worked much better than I thought it would do. Only slightly annoyance was the plugs a little stiff to ug into at first dies improve though with usage.

Works as advertised
As a laptop charger stops laptop from losing charge, so worth plugging when using in Car, plug sockets stiff to use give the impression not fully in. USB ports work fine.

Good but makes a noise.
Device is handy when using USB but to use the plugs you have to turn on a switch which then caused a constant noise which sounds like static coming from the device. A little worrying.
