USB Power socket

Hi we are renovating house, to include rewire

Thinking of putting one or two USB Power socket in

Havent seen them on sale in Ireland, are they expensive and are they a good idea;

An excellent idea, must consider this when I do my own self-build.

Don't forget about network cable and network ports while you're at it, wireless is all well and good but you can't beat good old copper for infrastructure, particularly for the likes of streaming.

Thanks Folks , re the network, will be putting in Cat 6


Had a look at one of the sockets, two USB ports, one for Apple , one for other devices , whats the difference between the apple and non apple :

"2 x USB ports; the left USB port is for Apple products such as the iPhone and iPad, the right USB port is for other mobiles and devices"

Hmm seems they output different currents..

from a quick search

Most standard USB charges for 0.5A. But not all USB are standardized - there are some that go for up to 1.8A and even the MacBook Pro is said to raise up to 1.1A when relevant. iPhone's charger do little more than 1.1A and it's pretty decent. That's why iPhone charging on regular USB usually take double the time to fully charge. iPad's charger are roughly 10W and 5V which translates to 2A.

There's nothing wrong that can happen with the charger because USB devices are made to work with the same standard voltage (about 5V). The USB hosts are only outputting the maximum energy it can provide up to what the client can receive. A 10W energy source will only give up to 10W and just 1W if the plugged device can only take 1W.

We have an ipad 2 , and three androids, looks like the ipad 2 is 2 amp
and the androids .5 amp

The current they put out is only the max current the socket supply transformer can supply. A 1.8A socket one will still work fine with a device that only needs 0.1 amps etc.

The device will take the current it needs according to its demand.

What wont properly is plugging a 1.8A demand device into a 0.5A socket.

Ok Thanks for clarifing, looks like I need USB 1.8 a, which should service either the apple or androids

Great idea. Just wondering how much energy these units use on standby

Is it like having your phone charger pluged in 24/7

Still almost nothing they have a transformer that will incur minimal losses when no lad is applied

No transformer, its a switched mode power supply.

Given how small some of the USB chargers are e.g. for the iPhone is there really any point anymore in installing USB sockets?

The ones I've seen seemed quite flimsily constructed and not really an ideal solution.

It's a shame that we have such a cumbersome mains plug design. The continental iPhone adaptors are absolutely tiny nowadays. You can comfortably carry one in your pocket.

We adopted shuttering of sockets very early on and used the earth pin to activate them, necessitating an earth pin on every plug, regardless of whether the appliance is earthed or not (in many cases a plastic pin). Other systems just use the two pins to open the shutters.

On the continent and in the US and elsewhere they just have a 2-pin plug for 'class 2' (double insulated) appliances and an earthing contact where an appliance needs an earth and the earthed sockets accept both. It means you can have smaller plugs which is becoming a big deal now that we carry so many portable electronics around with us.

The BS1363 plug we use here seems to assume everything's a 3kW electric kettle when in reality most appliances are very low power and the continental style plugs allow them to have quite neat plugs and reserve the big huge plugs for things like heaters, kettles, washing machines etc.
Always struck me as a bit nuts that we've the same size plug on a tumble dryer drawing up to 3000W and a camera charger drawing less than 2W

Well, it still is a type of transformer. It transforms.

Yes, I suppose lots of things are technically transformers
