Question: Is this a PA-3E or PA-10 (older model). The picture is that of a PA-3E (slim adaptor)? There is a diff.
Document: I purchased this adapter for a Dell Studio 1535, which originally came with the PA-10 model charger (90 watts too). It appears to be new with all the standard Dell markings. This charger has a longer power cord than the PA-10 and the power cable from the adapter to the computer, fits very snug. It does get hot while the laptop is in use, but no more than the original adapter. So far it is working well with no problems.
Less than six months after purchasing, I plugged this in, heard a pop and saw sparks and the wire to the power supply had completely blown off. Dell PA-3E Extra Slim AC Power Cord 90W
This is the second one of these 'made in China' PA-3E adaptors I've had now. The first one lasted for about a year before a wire apparently stripped and it began spraying sparks every time it was plugged in. I've had this one a month now and the outer layer of insulation has already pulled out of the 'sheath' at the end of the adaptor plug and I can see the wires inside. It's not like I'm running it over with a car, it's just everyday household use.
This charger/adaptor had an amazing effect on my Dell XPS M1530! Before, the battery would not charge on the original or other replacement adaptors (this is a common problem for this model often attributed to the motherboard, which costs 300-400 to replace).Now it charges! I can actually unplug it to use it for a few hours, and not worry that the cable will be jarred leading to shutdown! It was like Christmas came early.
This is the third slim, travel type power cord I have had. All have been Dell products and all have worked well. It is about 50% slimmer than the conventional unit. The new model has  a more flexible cord material that should last longer that the previous model as the stiffer material caused cracking in the outer sheath of the cord and eventually the failure of the unit. I like the improvements.
it does just what it needs to, and cost about 1/10 what best buy charges. i haven't had any problems with it yet.
The charger works with both our Dell Studio 15 (Model 1537) and Inspiron E1505. It's nice to have the blue light to indicate it is on.
Nice compact size and works perfectly with my sons older Dell Studio 1557. Much more compact than the original charger.
This Dell AC adaptor is really thin, making it easy to pack into a laptop case. I purchased it to power my Dell Studio 17, and it is doing a fine job.
Identical to the Dell factory included power adaptor. My first one lasted for many years. This one should last too. Glad I spent the extra money.
Answer: This is the PA-3E. I have one of each due to a bad one will interfere with sound to my DJ equipment. I use the 10 as a backup. Hope that was helpful.
