Can a 12v windshield wiper pump be run from a wall wart? I am putting
together a mist system for a terrarium, so it will run about 1 minute
2-3 times a day or so. If it will run from a wall wart any suggestions
would be great.

Wall warts ONLY handle currents up to about 1 Amp - MAX.

Um, not to give the op hope, but ...
See cat# dctx 1215 from http://www.allelectronics.com/
for a 1.5 amp 12 volt wall wart and cat # 16760 from
http://www.mpja.com/ for a 2 amp 12 volt wall wart.



Yes, these are OLD surplus designs -- new mfg. are generally now avoiding
(that is why they are on the surplus web sites/resellers).
They usually do not stay in the duplex outlet without screw attachment to
cover plate.
Readily available 1 and 2 foot line cord jumpers --- help with this problem.
These older designs stretched the definition of WallWart -- due to
transformer's weight !

New ones are more "brick like" with short AC cord OR use standardized IEC
jack.

The new stuff is nice. It seems like most everything new
is going to switchers. I suspect one of the factors is
the weight you mentioned. Take a look at the wall wart
switchers like Mouser part #'s
418-TR25120-04 2.1Amps
418-TR30R120 2.5Amps
831-PW128RA1203B01 2.5Amps
552-PSA-15R-120-R 1.25Amps
552-PSA-21R-120-R 1.67Amps

Allelectronics sells a switcher wall wart at 2.6 amps,
cat # PS-1226

For non-switcher new wall warts 1 amp see Mouser part #'s
553-WDU12-1200 1.2Amps
553-WDU12-1900 1.9Amps

A lot of choices 1 amp, but not necessarily suitable
for the OP. I suspect not. I posted a different
possibility for the OP.
