Some friends bought some cheap Android tablet, it seems to be an ICS based Zenithink 10" ZTPAD (hard to determine a model number). Cortex A9 based. Being the "computer guy" I got asked to set the thing up, it seems to be decent enough.
However it was supplied with an extremely dodgy power adaptor, in fact I doubt it's even legal.
Anyway, the friends are trying to get a proper adaptor off the supplier (doubtful) but in the meantime they agreed to pay for one, these are the parts I bought from GlobalPC in Christchurch:
M8925 9V2A Powertran plugpack
M9187 DC jack
Cost just under $32
