Introduction: Personal Portable Spot Cooler

Picture of Personal Portable Spot Cooler

Here a smaller version of from my last version of air conditioner.
do check it out its really cool and TRENDY
haha its really portable all you need to do is charge and go.
because the ice stored in it will last and stay frozen with only a fraction of melting for hours! then just pop it out. and turn it on.Its really great and super portable anywhere everywhere.
So far this is the coolest! haha..
DONT underestimate this thing.. it produces up to 108CFMs under only 7.2v that will blow you down for 2 straight hours. that is 50mins for cool and rest for fan LOL. haha hope you guys will like this. thanks for the figure! you know who you are.

Step 1: Getting Parts and CUTTING!

Picture of Getting Parts and CUTTING!

Heres what you need,
styrofoam board,a firm container, any battery source(rechargeables..go green!)
a pc case fan some cardboard and some time.
First, insulate the container by having walls of the styrofoam at all sides. all you need is Cut here and there and finally place a thin layer of plastic to contain water and make it leak proof.

Step 2: Steps to Waterproof the Cooler

Picture of Steps to Waterproof the Cooler

Place double sided tapes below and sides and use thin plastic or thick ones for your choice. and press down evenly.

then snugly fit the cooler into the container

Step 3: Making the Side Insulations

Picture of Making the Side Insulations

Here i will give yo utips on making the sides insulated and even below, i will not recommend you guys to use permanent markers to trace out the sapes. but instead use some thin opaque tape for markings as they are more straight and more well guided when cutting.
for shaping the sides, use a sand paper(abrasive) to make smooth edges.OMG CFCs!!!! im feeling sorry for that.

Step 4: Making the Lid for the Cooler

Picture of Making the Lid for the Cooler

This part is a little tricky ya all, to me.. you will need to have a nicely fitting top part so taht it will store the ice for long, it really help to keep my ice last 30-50mins longer and really effective, thus i wanted to include this too

after making the lid, attach a string or ribbon to make a holder to pull out the cover.

Step 5: Making Holder for the Battery.

Picture of Making Holder for the Battery.

For this, i think its hard to get your batteries, i wouldnt want to use 12v car battery as they are huge and a hassle to handle due to its weight too. For me i use my rc 7.2v battery, for you guys you may want to use 6 1.5 volts rechargeble laying around your house. USE RECHARGEBLES! not disposibles, they SUCK!.. haha
for me i just use the leftove cardboard for to hold the battery.ive also wrapped the ugly wires with some covering.

Step 6: Mounting the Fan and Making the Vent Spot Vent

Picture of Mounting the Fan and Making the Vent Spot Vent

Using your skills , you shud able to make a vent as shown in the intro pict with the carboard.
then now mont the fan, make sure that the fan is BLOWING IN
In this part, i also have th wiring neat by using tape to cover the ugly black red wires, and also made a holder or a battery compartment for the batter stickpack to fit in to power up the fan.. wee!! 60cfms ! for a 12v powered by 7.2 volts, its not that bad.
the shape for the vent for it is pictured in the next step

Step 7: Your Own Personal Cooler !

Picture of Your Own Personal Cooler !

You should end with something alke like this.

Step 8: Wee! Done

Picture of Wee! Done

Now, pop some ice in, and turn it on.
and i think this is the most portable, compact smallest spot air conditioner HAH!. hopefully, now its still on my study table, replaced my old mini airconditioner with this which it better. i find the air out is really almost the same as in my 2nd version of a/c and really, this is ultra portable.! haha. next i think its gonna be at my class table as its hot .



ssamat1 (author)2014-02-25

im a quest...what is the purpose of doing step 4?

Middle19 (author)ssamat12017-11-10

possibly to preserve the ice when not in use.

JulienG19 (author)2017-06-23

I'm curious, why do we have to insulate? I mean, if it "leaks" cold, it will also chill the room?

Middle19 (author)JulienG192017-11-10

well from what i can tell to its to protect the battery.

NickS21 (author)2015-07-21

I made a rendition of all the different coolers here, I did use solar and a 5 gallon bucket but use dry ice, man it lasts a long time.

Mostafa Omar 79 (author)2015-06-17

Nice project. I am going to try it.

clintdonaldson73 (author)2014-09-30

So I made something similar after a buddy bought this thing called an IcyBreeze. It works the same way using ice and water. Anyway I wanted to make something for a third of the price, well as it turns out his IcyBreeze won. My DIY just didn't work as well. It was a "cool" (no pun intended) project, thanks for the instructable.

skhanna7 (author)2013-03-05

i like your idea. thanks for sharing this.

sharadholani (author)2012-05-16

How to attach the fan to it? how to give it support?

Dipankar (author)2008-07-10

Very cool man, Why didn't I think of this before, but the name is misleading it is an air cooler and not an air conditioner.

anything which changes the state of the air whether that be temperature or humidity is conditining that air so i am sorry to say but it is an air CONDITIONER

farhanians (author)Dipankar2008-07-11

Ouh yah shure will rename it. hah btw im afraid that ppl will mistake for an air cooler. AIR COOLER . i think this is like more of a spot cooler.. spot air cooler heh but if you still find it as an air cooler, im okay

Dipankar (author)farhanians2008-07-11

Yeh.....Personal spot cooler is more like it.

farhanians (author)Dipankar2008-07-11

yeah thanks! gonna rename it .. PERSONAL SPOT COOLER hahas thanks

jovenhatsjr (author)farhanians2009-04-28

Can you kindly show how is it wired, i mean the power from batteries , am really poor in electricity but i really love the innovation. I've tried to make one but the batteries is becoming increasingly hot as i switch on .

68autobug (author)jovenhatsjr2009-11-28

it sounds like you are shorting a battery or batteries which will overheat the batteries...
make sure you have all the positive+ terminals red wires hooked together

and all the negative- black wires hooked together

just connect up to the fan...  if the fan blows the wrong way
just reverse the wires to the fan....

You can place a switch in either wire...  just cut a wire and connect to a switch... so the power goes thru the switch....

I have a 1968 VW beetle without air con...
this looks like a sure way to keep it cool during the summer months...

Yay for HAMS!!!


tinstructable (author)2010-12-02

Electronics only draw the power in amperages they need. A car battery would not hurt the fan at all. You could hook a fan like this up to 400 car batteries wired in parallel and nothing fancy would happen other than that fan would be going for a long time. If you wired up 400 car batteries in series, you would definitely obliterate the fan. So yes.

Yeah right!!! i had xbox360 2 in 1 fan and i hooked it up with 2 x 18 v batteries and suddenly the fans exploded and the smoke came out!

Wired in series, or parallel? You probably over-volted it. 12v is the normal rating for fans like that, so 1 18v battery probably destroyed it. I am right, go look it up.

terrilein (author)2011-05-02

I'm totally oblivious to the electronics aspect. Can someone please explain to/show me how the fan is attached to the batteries???

ashashank (author)2011-03-12

couldnt 1 simply use a cellphone charger to power the fan?

ashashank (author)2011-03-12

couldnt 1 simply use a cellphone charger to power the fan?

wingl (author)2010-07-12

This seems like a great project. A possibility is to wire it to power off a USB port. Any possibility to explain how this could be done?

Electroinnovation (author)wingl2010-10-19

yea thats easy just get an old usb cable and cut it open. I would test the wires to see which is the positive and negetive because i forget. the 3 volts from a usb cable would be enough to power it but it would not be very powerful.

Electroinnovation (author)2010-10-19

haha well i should try hooking up a car battery to my air conditioner...i used an old rc car motor LOL

jvan0907 (author)2010-08-17

Could it be wired to 5v eg usb 500 mah?

ducktape100 (author)2010-07-15

what kind of box are you youing

nutsandbolts_64 (author)2010-07-14

doubles as a swamp cooler lol

icedude007 (author)2010-07-12

Nice instructable (: I'm going to try this and power it with a usb port. Knowing your in singapore was helpful as it also gets very humid here in Hong Kong. Thanks man (:

marcusm73 (author)2010-07-12

how about adding salt to the ice water to drop the temp even more.

the dudemaster (author)2010-07-09

you know if you changed the innards up a bit it might work better. . . i would try this but i just don't have the time before i go on vacation. . . just take a food can (after using the food and washing the can out would probably be preferable) and drill some holes in it below the preferred ice level and put it directly below the fan and seal any gaps . . . .this would probably work better with just ice instead of ice water. . . i don't know if it would work but if anyone could find the time to try it it wouldn't hurt. . .

pc fans move alot of air at low pressure (opposite of an air compressor) the fan would not be able to push enough air under the water

endolith (author)2010-07-11

Put copper pipes in the ice water for the air to flow through, like a radiator

junits15 (author)2008-10-14

try putting some dry ice in it it will be alot cooler and last alot longer it is realy cheap if u know where to look!

nolte919 (author)junits152008-10-28

soooooo... where do you look for cheap dry ice? Inquiring minds want to know.

junits15 (author)nolte9192008-10-28

well that really depends on where u live and your local laws ect. ANYWAY you have to try and find a local distributer near you because dry ice costs ALOT more when shipped, because you have to pay for the dry ice that subliminates while being shipped. (the ice that turns into a gas during shipping has to be paied extra for)and sometime gas dirstributers will sell it, because dry ice's only ingredient is co2. and usually the cost of dry ice is somewere between $1-2 per pound.

hughscott5 (author)junits152009-06-25

You should check local super markets, I used to work at one and they usually have it on hand in case of a power outage, to keep the frozen food from going bad. The one near me sells it for $1 per pound. If you do use dry ice, make sure you are in a well ventilated room. As junits15 said it's just co2, too much of it can cause oxygen to displace, which can lead to sickness or even suffocation. You should be OK with a window open and a fan blowing. Great Instructable by the way!!

nolte919 (author)hughscott52009-06-25

HA! I only asked that question 8 months ago. But thanks for the answer nonetheless. I'm actually down with the supermarket dry ice. It was just the way junite15 said "it is realy cheap if u know where to look" that made me wonder if he knew of a source of dry ice I'd never think of. The supermarket is in fact where I get my dry ice. Thanks.

robotmastern (author)nolte9192009-07-28

dont use dry ice in it if your using it in a car as you could suffocate

it wouldn't be THAT much CO2

junits15 (author)hughscott52009-06-25

Really? Thats good to know, what brand store it the one that you are talking about. So I would just ask someone behind the counter?

i seed it at grocereys storeses sometimeses........

checho5123 (author)2010-05-25

 Hey man one question, which method works better, using the radiator like u did in the big one or just using the cold air that the watter gives off?? i know the small one probably cools less because of the size but which method works better overall??

This is great.. I think i'm gonna use the freezable ice packs in the cooler instead of ice and water. When they thaw out, i'll just throw them back in the freezer and switch 'em with new ones.

Bridel568 (author)2008-07-13

dude drop the 1.5v just use 2 or 3 9v`s they make rechargeable 1s but I don't know were to get them. but wow! the fan really has a kick. I got the tip of my finger in it(it really hurt) but thankfully it wasn't my whole finger. yes it maybe a 12v fan but I connected 2 new 9v`s and a used 9v and man does this cool you off it might make ur acp work better

farhanians (author)Bridel5682008-07-14

hahas. yah 9volts will do. but mines 7.2volts. hehes still having the kick!
lol but 2x9v= DISASTER 18volts hahs

68autobug (author)farhanians2009-11-28

Use 9 Volt batteries in Parallel so its still 9 volts..
the more You use the longer they will last...
and rechargeable ones would be excellent...

just have all the Positive+ terminals hooked together
and all the Negative- terminals together
all equals 9 VOLTS...

Lee   VK2LEE

ReCreate (author)farhanians2009-07-31

i once over powered it with about 60 Volts worth of 9V batteries before XD

iluvpandas4 (author)2009-06-10

hm this looks like a really great idea and since i don't have air conditioning in my car i think i'm going to modify the power source to plug into the cigarette outlet. i was also wondering, how big is the container you used? i know the size probably won't matter too much since i did see another instructable using a styrofoam hamburger container, but i was just curious.
