Super Cooler! Peltier Heat Sink & Fan 

Super Cooler! Giant assembly consists of a 

Peltier effect cooling module mounted inside 

a giant heat sink assembly. It was made for 

a recreational cooler and features a large 

aluminum heat sink which gets very cold. 

Next to the large heat sink is a heat insulator 

which is attached to the smaller heat sink 

which releases the heat as the large heat sink cools. 

We include a 12VDC fan which you place near the “hot” side to increase the cooling 

from the large heat sink. Overall approximate size is about 5”L x 5”W x 3.9” Thick. 

Has red and black flexible leads for power. Operates on 12V to 13.8VDC @ 6Amps. 

This is the most powerful cooling module we have ever offered!

them “AS IS” only. Some may even have tarnish or slight 

corrosion on the battery contacts so remember you are 

buying these “AS IS” (no returns) and they may not work 

even if you put new batteries in. We sold this same set

Assortment of various size Polycrystalline 

silicon solar cells. 

You get 4 cells each capable of 

delivering high current to power 

motors, etc. from the sun. Each 

cell no mater how large puts out .5V open circuit voltage, 

however the size determines the amount of short circuit 

current. In this assortment it will vary from 150ma for the 

smallest up to 950ma for the largest. The smallest cell 

is 2 1/4” x 7/16” and the largest is 4 1/2” x 1 1/2”. May 

have slight edge chips. Complete with soldering instructions. 

These would cost over $14 if you purchased them 

individually.
