It depends what you want to test. A 5 watt bulb - Yes. A starter motor- No.
There is one for sale on flea bay that I am looking at. Max output is 1 amp.
Is that sufficient?

OK, why not just use the car socket then?
Sure sloggy but you are hardly going to test relays, 5w LED's, instrument cluster parts, back light, switches and generally things that would normally go through a resisted circuit or a relay with that are you? \not sure how you would put those gigantic crocodile clips onto say, one of these:
Pinno. If your only doing the odd lamp or switch then old battery with a battery charger would do, otherwise look for something from bremi, isotech or thurlby thandor basically they're lab power supplies normally 0 to 30 v various current capacities from 3amp to 30 amp. Typically I threw an old bremi one away not long ago as I'd never use it again and it was a bit tatty for ebay or so I thought. Remember wiper, seat, sunroof and door drive motors all use above 4 amps or so especially if still attached to whatever there supposed to drive. Seem to remember 7amp being max av current allowed by most OEM car makers approx 12 yrs ago. Hope this info helps.
I can see you have tested a starter motor.If you do not use a vice the first time you certainly do the second.
