The broken promise of one power supply

I recently got a Dell XPS 13 to replace my slightly aging Lenovo thinkpad X230, which has been giving me a lot of head aches recently. Its a very attractive machine, being super thin and mainly metal instead of plastic. I thought about it long and hard before ordering it because of the lack of ports and extendable battery. In actual fact its got a similar battery to those seen in phones and tablets, aka non-removable. I guess Mac users will say “so what?” but no laptop I’ve ever had, has had nonremovable batteries.

The thing which nudged me about the Dell XPS 13 was a USB C port. USB C I’ve had ups and downs with since my Nexus 5X, but a year later I like the technology and want everything with USB C. I had imagined charging my laptop & phone with my new portable battery pack with Solar Power. But plugging my Nexus 5X into the laptop with my nice new USB C to USB C cable, selecting reverse charge; expecting something to happen but nothing. I thought it might supply a tiny current at least. I wrote it off as not enough current and waited till I got home.

At home I tried my solar battery charger with USB C, once again thinking this would supply enough charge to power the laptop even for a short while. Once again I was disappointed to find it not charging.

What gives! My dream collapsing, I hot the web and found a reddit thread and the PC World piece which made it crystal clear.

Seems the dream isn’t dead but its not looking good for portable batteries packs. Maybe it might work with some of the wall chargers however, will have to try my Nexus 5X wall charger later.
