London’s payphones turned into smartphone chargers

That's cool and all but you'd need to leave it in there for an hour to get a half decent charge. Rather just tear down those relics I think; nobody really needs them anymore and they just take up street space.
A good ten minute charge should last a few hours if you don't overuse the device might even be enough for a quick call
Add free WiFi while you're at it- the line is already there...

I wonder how long those USB ports will survive?
