Can i hook two power supplys together

Ok this is wat i got a 12v 1.5a fan but i only got a 12v 1A power supply from xmas blow up anyways the fan blows but not full speed so could i hook up a phone charger in parallel 12v .5a to achieve my 12v 1.5a needed

no if what your asking is what im thinking, if you take a 12v 1a charger and plug it into a 15a outlet its reduces the current to 1a, if you take a 1a charger that is producing 1a and have to connect to a .5a charger then it just reduces 1a to .5.

correct me if im wrong

I thaight current is addivtive in parallel

for what it's worth, putting batteries in parallel increases it's capacity, putting them in series increases it's amperage. not sure it helps but they ya go

sounds like you need a 1.5 amp power supply
