USB power supplies (chargers) are available with different current ratings. From 1 amp per socket to 2.5 amp. Most of these are 5 volts (the standard for USB devices).

Thus a 2 amp USB socket, at 5 volts will deliver 10 watts of power (2A x 5V = 10W)

The I pad uses a 10 watt charger as standard. While mobile phones tend to use c 5 watt.

However if a mobile phone was charged using a 10 watt supply it would charge more quickly and not be detrimental to the battery.

Similarly an I Pad would be best charging in a 2A, 5V USB but could also charge in a 1A, 5V USB but would take longer to charge.

With regard to USB charging of laptops or computers this is different story.

Laptops need around 3A, 20V to give 60W – this is not available through USB but could become available over time with next generation USB type C developments.

As with standard desks, most sit stand desks incorporate a cable containment system under the desk.

The problem with sit stand desks is they will move up and down so that any cable containment/ cable spine used for getting cables from desk to floor needs to be extendable. There are extendable systems that allow this available.

Alternatively the cable basket may be kept at the same height when the desk moves up to a standing position. In this case the cables are normally housed in a cable chain system supplied by companies such as Metool or Kabelschlepp. These allow longer cable lengths to be used (to allow a stand position) without the cables becoming snagged or tangled.

That depends on the type of desk you are using. Many desks incorporate cable trays or cable baskets designed to house power modules, cables and data cables.

Power and data cables should be separated from each other in the cable containment (tray or basket).

Many desks do not include a method of containing the cables when they are taken from the horizontal cable basket to the floor. This is best done using a cable riser or spine which will contain the cables as they descend from under the desk to a floor box.

There are British standard guidelines for installation of electrical systems into office furniture, this is BS 6396: 2008.

The basic rules that apply when installing power into a desk are as follows:

  • Sockets used to power desk equipment should be individually fused sockets (not available on retail standard extension lead type sockets)
  • Each 13 A plug supplying power to the desk can supply either:
    6 sockets, each one fused at 3.15A, or
    4 sockets, each one fused at 5A – for use with lower current desk equipment such as laptops, mobile phones etc
  • The power to the desk must be connected to a mains supply using a 13A plug
  • Max. rating of the electrical system must be 240V 50 Hz 13A.

These desk power socket modules also use the Wieland 3 pole connector system, which allow flexibility on power cable and link cable lengths.
