they should all be 5 volt it's the ampage they deliver that dictates the charging speed. 2.1A for fast charge I believe
#2
2.1A OUTLET FASTER CHARGE / THAN 1A

THEY NORMALLY HAVE ONE OUTLET OF EACH

No point, those wall sockets sap energy.

more then if you had wall plug fast charge?

intresting or you mean when nothing plugged into it is using energy?

I've no idea what he means either.

Surely the purpose of a wall socket is to release energy?

You are looking at 2A minimum.

They are normally 2.1A which is shared between skts. There's a newer 3.1A also shared. http://www.screwfix.com/p/lap-13a-2g-sp-switched-socket-3-1a-2g-usb-charger-white/4087p

There was a deal on here a while back with one that had 2.1A but if you used only 1 skt it would give the full 2.1A. But I can't find the deal. :)

What a load of rubbish. oO

Found it. It's 4.2A shared between the 2 skts. http://www.hotukdeals.com/deals/another-usb-socket-14-08-screwfix-2507333:)

The latest standard is USB Power Delivery. It does provide several voltages, 5v/9v/15v/20v, but the official guidelines for quoting capacity just use the total power output and require all lower voltages to be supported. So a 30W socket, for example, supports [email protected], [email protected] (27W) and [email protected] (15W). Anything higher would support 15V up to 3A and 20V above that 45W but no more power at 9v and 5v.

Most devices supporting it use a USB Type C connector and I believe they will require the same on their power source for the full capacity.

I haven't seen any wall socket USB Power supplies supporting it yet, although there are a reasonable selection of plug-in ones now, at least at lower power levels.

Not getting cheap on me now are you ? ;) Joking aside it's not too bad if you want all that stuff and to forget about it but at that cost I would expect av1200 atleast :)
Someone must be buying them though. Maybe the apple crowd as it's cheap to them.
