Special car charger part for laptop

[focaner]

I want to get a car charger for my old Lenovo T61 laptop, but genuine ones are impossible to buy and the third-party versions apparently blow your car's fuses sometimes.

I already have a standard 90W 20V charger for the laptop, which consists of two cords: A wall plug ending in one of those two-pronged rubber cables that the original Xbox and PS2 used for power cords, and an adapter which that two-pronged cable plugs into. (See image.)

I figure if I can replace the wall output cable on the left of the picture with a car power outlet cable which ends in those same two prongs, I can just use my existing adapter. But I have no clue what this type of two-pronged plug is called, so I haven't had any luck searching. Any ideas?

(By the way, I have also used a 65W 20V charger with no problems.)

Have you considered something like this?

I'm not endorsing this specific product, it's just an example of the concept I'm referring to.

Ah good point, that'll probably be easier to find. Can I assume that as long as the product in question supports at least 90W (my laptop's supposed max output), it won't blow my car's fuses? So, is, say, this adapter: http/www.amazon.com/gp/product/B001539B7O/
sufficient to use safely? Apparently the max power usage for my laptop is supposed to be 90W, 4.5 Amps -- aka 20 volts.

Yeah that looks good to me
