The chargers will give a damn in the adapters, which deform easily. False contacts appear very quickly and Chargers no longer hold or barely. Let's not talk sparks the connections and a burning smell that appeared once when I have connected a netbook charger ...
March 1 adapter is good, but when you not buy expensive, we only have what you deserve, that is to say here: the stew!
I strongly advise you to buy a slightly more expensive adapter, but also more robust and reliable. They have deeply disappointed me.
