Dell Laptop Charger Went up in Smoke!

Higher wattage allows the processor to run its hidden cores. A dual-core processor suddenly becomes quad-core. It's great!
1. 65W vs 90W means more power output.
2. It worked better because unlike the OEM that smoked (and the 3rd partry one i got with the laptop) This one worked the second it was plugged in whereas the OEM had to have the end in the laptop wiggled to work.
19.5V @90W means more power than the battery 11.1V 1500Mah. My laptop sets prevormance mode when plugged in and low power mode on battery means the laptop drastically slows down the processor power to the point the system lags at mouse movement and 480p video
Sorry, but the computer will draw what it's going to draw and having a PSU that's capable of supplying more doesn't mean that it's going to.
I use Apple charges sort of interchangeably. For Powerbooks/iBooks you have 45W and 60W chargers. For Macbooks/Macbook Pros you have 65W and 85W chargers(at least with Magsafe 1). There are also 5W iPhone chargers and 10W iPad chargers. A 13" Macbook or Macbook Pro doesn't charge any faster or run any better(even in performance mode) with an 85W charger. A Titanium Powerbook or 12" iBook G3 doesn't work any better on a 60W charger. iPhones don't charge faster when plugged into an iPad charger(although I charge mine with one most of the time so I don't have to keep up with two chargers).
I try to not use lower rated PSUs than specified, but they will generally work at the cost of extended charging time. I've been known to plug a 15" MBP into a 65W charger, but try not to make a habit of it.
You can go lower wattage on the MacBooks and be fine. They advise against the opposite, at least, that's what the Genius Bar said to be. I use my MBA MagSafe2 on my 15inch sometimes, but never the 85W on the Air.
I've always thought it was the other way around.
After all, the TB display has an integrated 85W Magsafe 1 and was designed for use with everything from the 11" MBA up through the 17" MBP(RIP).
Yeah, I'm not sure. Just going by what the Genius told me.
The MBA charger basically trickle charges my 15inch Pro. Sort of like putting a battery tender on a car for storage?
I've never had an Air so I've never had a 45W charger. I have several Macbooks, though, along with a 13" Pro, and a couple of 15"(my current main machine is a mid-2012 "Classic" matte hi-res). I use the 65W chargers with some frequency with the 15" computers(I often don't carry a charger with me, but instead just leave them where I use them most often) and do notice that the 65W ones charge a little bit slower but not by a huge amount. My 2012 is set for "best performance" when plugged in-which means it only uses the discrete GPU-although I rarely do that much that even stresses the GPU.
I also leave PPC chargers scattered around, as I do use Powerbooks/iBooks still with some frequency. I've actually found them to be a bit more sensitive at least in some cases-i.e. the battery on my 17" Powerbook G4(A1139-late '05 with a high-res screen) will actually discharge when I'm using it with a 45W charger(although the 45W will charge it with the computer asleep). I also have trouble with 14" iBook G3s and 45W chargers. I would just keep 65W chargers around, except that some 65Ws have an outside plug "barrel" too large to fit under the hinge and plug into the charging port on a TiBook.
