Amazingly in the last month I've had two punters come up asking about power to charge their phones, but not actually having a charger on them.
So let me get this straight, you're asking about charging your phone, yes, but you don't have a charger, yes.....right.

Haha. To be fair, a lot of places do now have charging stations with a range of cables. Westfield has them, and you get 30 minutes for free (I think) and can of course go back and use another box if you need to. Perhaps some trains could have these instead, although lost property better prepare some more storage space.
And that's another thing. We hear people saying they want power sockets over carrying a portable battery charger, but many phones don't support fast charging yet. For some trips, you won't fully charge your phone before having to unplug and alight. You may come away having gained a few per cent at most.
With my battery pack, I do have fast charging (0-100% in 90 minutes) but I'm charging while I walk along the platform, up the stairs and along the road. Grabbing a few minutes here and there on a train isn't really convenient for me, and I also try and avoid carrying mains chargers as they're often bulky.
