Power Adapter Question

post #1 of 8
Thread Starter 
I couldn't figure out where else to post this.

Since I finished the year at school, I recently moved home. At home, there is one family computer and that is it. I have my desktop and my laptop that I want to get internet access to. This requires me to bust out my old wireless router and set it up (as well as buy a cheap wireless card for one of the desktops so both don't have to be close). However, I seem to have misplaced the DC adapter for the router.

It says that it needs 9V 1A. The closest I have is a 12V 1.5A from my old external HD. Obviously, I'm reluctant to use it for fear of frying my router. I called local stores and they sell adapters, but they're relatively pricey ($30+). I tried browsing stores online (WalMart, Target, etc) to try and find a cheap thing to buy that would come with the right adapter, but I'm not having much luck.

Would it be better to just shell out the money for a new router since this one is fairly old anyway? In this scenario, I'd try the 12V adapter, since I'd be buying a new one anyway.

Please help! I hate using the family computer

Stupid 2.5Ghz Celeron D. I miss my Quad.

I would not use a 12 volt ps for 9v rated power requirements. Are you sure that you do not have any old portable phones laying around the house? Most of these phones are powered by a 9v power supply. It is too bad you do not live down the street from me because I have several 9volt power supplys that I have accumalted over the years. (I never throw a good power supply away)

You could always go over to your local Ratshack and see if they have a universal supply that is not cost prohibitive.

Already checked Radio Shack. Even have one of the iGo things, but they don't have the right tip.

I have lots of old phones with 9V chargers, but the plugs don't match up. The router has the basic yellow circle pin plug deal, while the phones have all sorts of configurations. I think my old Nokia may have had what I need, but I let my step sister use it and she lost it.

there are universal dc adapters that allow you to set the polarity of the tip/ring, let you set the plug male/female, and let you set the voltage - snoop around. I know Radio shack used to sell them, you should be able to find them even if Radio Shack doesnt stock them anymore

If you get a universal as clockworkorange suggested, you should check it with a multimeter. I have one that overvolts by 3v no matter the selection. D:

EDIT: Fixed post, as I said OP suggested the universal. D:

In the process of cleaning my room while unpacking my life and getting settled, I found a 9V 1.1A adapter. I'm using that now, seems to work fine

Thanks for the suggestions though!

did you check the polarity first? I mean I guess if its working and it hasnt fried then its the correct polarity, and <= voltage.

in case anyone wants to know how to read the polarity on dc adapters, theres usually a diagram for tip and ring like:

+ ------( ------ -

in that example it means the RING is positive, the tip is negative
the voltage is usually printed on the adapter housing
the diagram is usually on the adapters and on devices that accept the connector. These two things should match before connecting or youre not using the correct adapter and can damage your equipment

Hmm, never knew that. Thanks! Should save me some electronics in the future.
