200+ Watt Laptop Power Supplies

[teslanv]

I would like to find a high wattage (200W or so) Laptop Power Supply to run my iCharger 106B. Input Voltage cannot be more than 18V.
Anyone know of a laptop or maybe a printer power supply like that?

I had a Dell Precision M6400 ages ago that had a 210W Power Supply. It was a Dell PA-7E type power supply, but it's rated at 19.5V, so I am thinking it won't work with the iCharger 106B+

I just found this little gem. (Dell DA-2 216 Watt USFF Desktop Power Supply)

It's the perfect mate to iCharger 106B+

And you can connect multiples in series for 24V, 36V, etc. They are ground-isolated.

You could put a power diode or two on the lead to drop the voltage to 18V.

Better be a fat diode to dissipate ~10W.

It's all in the spec sheet. There are loads of diodes that can tolerate more than that much power. Heat evacuation is the problem, and that's solvable.
