High pitched noise...?
Can anyone else here a high pitched noise after installing these? Checked all connections are fine but can here a very annoying high pitched noise coming from the plug. Heard it can be due to a converter in a usb plug...any ideas?

Yes, I have the same issue with a few of these that I have fitted. I am having to change them for the client for an alternative brand

Does socket provide fast charging?
Asked by: Batchjb1246786
Its noticeable that there is no reference to quickcharge or similar so unlikely to be as fast as a purpose built charger but not bad for normal phones.

Are the USB outlets fused?
I had one of these twin sockets fitted professionally last year. Today the two USB sockets are dead, but the 2 mains sockets remain OK.
Is there a fuse or reset inside the unit, protecting the USB outlets? How can I fix them?

MK are extremely helpful. If USBs stop working, disconnect socket for 10 mins to allow capacitor to re-set. Didn't know that! Worked a treat.

Standby power draw - cost
In the answer to a Q above, MK say the draw is 150mA on standby.
(150/1000)*240 = 36W.
(36/1000)*24*365 = 315kWh p.a.
I pay 15p per kWh at the mo = £47 a year just on standby
Is this right?

Do think that’s correct. MK state current consumption 150mW ( that power consumption I suspect) that’s .150/230 = .00065 amps
Power consumption per year is .150x8700= 1.3kWh p.a. About 20p.
MK also state the current consumption is so small it’s difficult to measure.

USB standby current draw
When no USB devices are connected to this socket, does it have a zero standby current draw, or is the USB charging circuitary always powered?
Asked by: Snowdonia
Mk state that the current consumption is 150mw. Is it 150mW power consumption or 150 mA current consumption? I suspect that its 150mW . If that’s correct that’s 1.3kwh p.a. (About 30p). If it’s 150mA that’s 34 watts. That’s a huge amount for an off load device per year.(about £40 p.a.) can’t be right.
