DONT USE ALTERNATIVES
i had 2-3 things in which my adaptor got spoilt and instead of buying original i thot what the hell ill jus buy a dupliate which is 1/4th the price
but then all my things got spoilt cuz of that
i had an external HDD which had a seperate power source. i used a local-make adaptor and it fried the HDD
i had a printer...same thing
and i had a laptop and i got a diff make battery which was supposed 2 b fully supportable with my laptop but after a month or so smoke started comin from d edges of d laptop and i spent a shitload in getting that repaird
so buy original cuz im sure ull regret it later
