The following PSU looks good, especially as it has a separate lead, but
I see it is specified as 5.35V at 2A but according to Wikipedia USB power should be up to 5.25V. Not sure why the difference.
Although you may not have used that one, can you recommend any other PSU for the PI 2B?
BTW, I found another one which purports to be from The Pi Hut but according to some comments customers have received ones which are rated at 1.8A instead of 2A.
