No, it's not actually about mad scientry. Sorry. Though as a product design student, I'm always open for ideas for mad gadgets. That's a serious sentence, I'm taking the 'experimental creative product design' class that's basically just asking for a mad gadget for an end product.
What I want to ask in this thread is something a bit more conservative. I want to buy a vacuum cleaner for car. You know, the one where you put one end of the cable into the car's lighter hole.
The twist is, I don't have a car. I want to use it in my room to clean things around my bed and pc. No, I don't want to use that tiny usb vacuum cleaner. Nor a real vacuum cleaner (it seems like an overkill). Or I'm just bored and want something to do and those two things seems a bit too easy for my taste.
So, I figured that what I need to do is, buy an AC/DC adaptor, and connect the cable from the adapter to the vacuum cleaner using mad scientry and a whole load of duct tape. I already got the vacuum cleaner that I want, it uses 65 watt of power and, because it use Car Accu, I suppose it uses 12 volt of DC voltage. But what I stumbled upon is this.
Electric Current (you know, that thing measured in Ampere or coulomb/second).
It's been a while since my highschool physics class, and I kinda almost totally forgot about electronic (I'm more a conventional analog rube-goldbergesque gadgetry guy).
Does electric current matter in this case? I know the definition of electric current, but what does it matter in practical sense (I know what voltage and power do in practical sense, but not electric current)?
There are a few adapter in that electronic store, all differ in the matter of... something like max electric current? Anyway it's like, 500 mili ampere, 650 ma, 1000ma, and 1200 ma, though I don't know what difference they have except their prices. Does it matter which one that I use?
Thanks for your help.
you guys will be spared when I got the world under my control later
