mobile test station, need opinions!

[revoracing247]

hey guys, for a while i've been wanting to set up a mobile test station (kind of like the one mead has) so that i can test my boxes and what not with out having to go put it in my car and start it up and all that hassle, and also for in my room or something.

anyways there's a guy near me selling an ac/dc inverter and it puts out 13V dc and i was thinking about getting that and then a 1farad capacitor so that it'd handle the current draw. i've seen a guy on youtube use this set up im pretty sure to test his boxes in his room and what not.

just wondering what you guys think about doing this.

btw im kind of on an extremely low budget (college ) so i can't buy like a $100 batt just for this.

any opinions would be a big help! even if its a

you're going to need to know how much current the power supply does at 13v. once you know this, that will determine how large of an amp you'll be able to test/run.

Stay away from Caps. I think Steve has a couple of XS D3100s and a XS Intelli-Charger with a Kenwood Deck but that can get kinda spendy.

Another option is too look around for a computer power supply. I have one laying around here that was in a computer someone was throwing away. The label claims 20amps @ 12v. Of course, some of those power supplies you can un-earth the grounds in them. By using 3 power supplies, and using their 5v side ran in series you can get 15v power suplly that will have probably 30-40 amps. There are some vids on youtube on how to do it. I know thats a bit complicated but at least it would be something to do.

honestly probably not much and that's why i was saying use a cap for the current draw.

well that was my second option was to use batteries instead of caps but i don't know how to hook up the dc power supplies to charge the battery correctly and what not, or how to hook it up right so that it acts basically as a current buffer for the power supplies. and i've had weird experiences with charging a batt while trying to use it as a mobile stereo power supplies. and i don't have a charger to dedicate for this

that's actually how this guy on youtube had his before he changed it and he had a cap to help with the current draw of the amp. and well i have a guy near me selling a 13v dc power supplies and i just thought that'd be a little nicer then 3 comp power supplies and plus it'd be at 13V not 15V which some amps i guess have a hard time with at 15.
