works like a charm:

btw: Yes you can also Solar Charge your phone with this 🙂

I would buy this adapter instead:

  • and connect the 12V cigarette lighter socket “DIRECTLY” to the battery… so you can power a laptop (which draws a lot of power straight after you plugin your laptop’s power-supply (just for a few seconds)  startup-current/”Einschaltstrom”, the charger can not handle such power surges)

  • of course it is important for your laptop power supply adapter should be 12V ready
