AC Adaptor (for Acer A510 Android tablet), Good Manufacturing, does not heat up and runs continuously connected to the power outlet. The micro USB port that connects to the tablet is bent, that's a good point. We can s' to use so even lying on your back without the risk of damaging the outlet. (This was not the case of the micro USB socket of origin) The charging time is the same as the original one. Product a bit expensive but at least it comes quickly. No regrets.
