On the charger itself, it is a very good substitute. It looks good, probably designed around a block FSP Group changed slightly (so good). And unlike the original block, it also has the advantage of having a grounding connector.
However, this model is slightly larger and has no LED charge indicator of the original charger, which it intended rather to sedentary use.
In short, this model fulfills its role very well and the advantage of being much cheaper (and easier to find!) The original model.
Finally, I also applaud the fact that delivery is ensured by Amazon, because I could recevooir my charger within 24 hours with the delivery in the evening and I have lost very little time in my work.
