My Dell power adapter for my x51v had one of it side "buttons" that releases the metal latch to secure on either side of the dell broke off earlier this week. Seeing that the
generic power adapter available from Semsons was cheaper (Aximsite discount as well) than the one from Dell, I bought it.
To my pleasant surprise, the width of the adapter is about 1.2 inches while the Dell is about 1.45 inches. A couple of neat things as a result:
1) This power adapter fits perfectly within the opening provided in the
Magnesium Case and doesn't touch the case. The width of Dell adapter would always hit the case and make the fit somewhat less secure.
2) The power adapter passes through the feet of the
Cheap Axim Car Holder enough such that the x51v now sits on the feet of the car holder with the power adapter being able to come up from underneath and secure onto the x51v. This includes the x51v being in the Mag Case with the Mag Case resting onto the Car Holder. Before, I would have the Dell power adapter resting on top of the feet of the car holder, now it passes underneath and through.
I've had no problems with the Semsons power adapter actually charging the x51v. Semsons was quick with the delivery (and I now have a second one on the way).
