240W Power Adapter for Dell Alienware M15 R2 R3 R4 R6 R7 Alienware 15 17 M17 M11X M14X M17X M18X X15 Area-51m PA-9E, Dell G15 G7 G5 G3 Gaming Laptop Charger with LED Indicator 7.4mm Tip

I use this power supply to power my PEMF controller. It is strong and works great!

Good quality, works perfectly

First up, this should work for almost any Dell laptop in the past 10 years. All the ones it lists should work, and I can personally vouch for the G15 gaming laptop, but it should also work for any Latitude with a barrel power plug. The laptop will auto-regulate the input, and will use as much as you give it that it can handle, so even if your laptop came with a 65w or a 90w power brick, this will work, and it might charge your battery faster.It looks exactly like the official Dell one. The brick itself is the same size, same weight, same specs, same detachable wall cable, and the plug that goes into the laptop has the same blue LED that lights up when it's plugged into the wall. The only thing different is the label on the brick (see picture). If that bothers you, I guess you should spend twice as much for the official Dell one.For us, this one works perfectly, and is great because we don't have to keep moving the power cable upstairs or downstairs with the laptop. It makes everything much easier.

The size and weight of this power supply can be described as being like your Granddad’s Oldsmobile: “Big and heavy.” It works well, but is not with the best weight for lugging around in a backpack. It works extremely well, by supplying up to 240W, surpassing the minimum specification of a 180 watt capacity. I’m spoiled by having a laptop power supply that is much smaller, maybe one-fifth of the size of this one, on a newer laptop. To be fair, this power supply is the same size and weight as the OEM (original equipment manufacturer’s that came with our Alienware 15 laptop some years ago. And, one would be very hard-pressed to find a small power supply with adequate output and a compatible plug. Thus, until you’re ready to shell out $500+ for a newer model laptop, this power supply is your best bet if you have an aging Alienware 15 laptop like ours.

I'm updating my recently positive review of this charger to reflect how it is after not even 3 months of use. Tonight, while playing a game, the charger stopped working. When I reached down to check and see if anything got disconnected, the brick was extremely hot to the touch. The label on the back was starting to bubble up. I'm glad I checked it when I did, who knows what could have happened if I hadn't.
