I have a recently moved to the US, but my cellphone charger has a British plug. Therefore I have use an adapter, which makes the whole thing very cumbersome to carry around. As I always have some USB outlet like my laptop around anyways, I got the idea to make a USB version for charging the phone.

Check what voltage the power adapter generates. For my Samsung model it is 5V DC, which is just what we want.

Is 5.3v always to be expected form a usb out or is there any way to < or > the voltage output. Or is this a daft question?

According to the specification of USB, you get 5 V±5% with 100 mA per device from a port. However, your cellphone might require a different voltage, so best check the power supply first. It should state the voltage on a label.
