no need to buy severan new poweradaptors, Magsafe 1 and 2... thanks !
Ho hassle no BS... plug and play (but first plug and pay... :-)
so far perfectly working with my old power adapters (two 60W, both magsafe1+magsafe1/2chenger), without heat up.
As described in the specs, didn't work with 45W adapter. (This is surely fair.)
Perfect to accommodate power connection for thunderbolt display to be macbook pro.
