In practice I have found that the short, stiff lead of the Powermonkey strains the connection with the mini-USB port on the phone.
But, it is possible to buy 1ft and 3ft USB to
(Right Angle) Mini-USB leads from Amazon. These are much thinner cable.
Change the Monkey Nut on the end of the PowerMonkey to a female USB (supplied with the Monkey) plug in one of the longer right-angle leads and there is no longer any strain on that mini-USB port.
