I would first like to congratulate the seller sends to the speed of the charger.
The charger comes as a classic Charger, it is pretty good and pretty solid air, however, there clearly has pluses and minuses to each product.
Start with less.
First we perceive that the weight of the charger is heavier than the original and it clutters a little more your bag, so for those looking for a lightweight computer that is somewhat contradictory. Also the charger is basic does not have the LED used to indicate whether the notebook is charging or if it finishes loading, which was very convenient.
Aside from that the charger is very well, and does its job, plus it looks more "safe" since it is entitled to a grounded outlet that is not found in the charger to origin (so be careful with those that would have taken too small).
