Air Compressor

Yep, I use it for both my roadie and my MTB. I can get 120psi no
worries🙂
Mine's got a cigie lighter connector on it. They would draw a bucket
load of current, so if you wanted to run it off mains you would need a
dirty great big voltage converter. That's why they run off car batts,
it makes them cheap to make.

dirty great big voltage converter that can supply the current. That's
why they run off car batts (they have no hassles suppling massive wods
of current), it makes them cheap to make.

Do you know the model/brand of the one you have? Was it the $19.99 one?

Thanks for the info.

is it one of the ones on this page?
do they have how many amps they draw printed on them?
depends what you are like messing with "stuff"
the only thing i can think of that most people might have laying around, is
an old pc power supply
even the old 130W one i use for charging batteries puts out 9A on the 12V
line, that might be enough (might not be to). but 130W is a pretty small
supply
if you have one and are interested i might be able to help if you need it

Cigie lighter would imply less than 10 amps (the fuse ratings on at
least some ciggie lighter sockets)

A spare computer power supply is good for 8 amps, possibly with the 5V
line slightly loaded by a 3W resistor.

Myself, I'd just use my 80A surplus power supply from some kind of
router -- good for turning pencils into red-hot heating elements 🙂

Do they have pressure gauges?

I mioght just have to invesigate...

I have had it for a couple of years now, and it is still chugging away.
Best 20 bucks I've spent🙂

From the pic in the flyer it looks the same as mine.

Yep, mine has a pressure gauge, though I can't say how accurate it is
as I don't have anything to cross reference it with.

You may be better off using a track pump. They are expensive but you do not
have any power issues.

I'm on my 4th 12V compressor. This time I forked out $80 or so
for a decent one after the 3 failures ($20 models) over about 8
years. I use mine quite a lot though - 5 bikes and 4 cars in
the family. I do the cars at home (with the tyres cold), and
that puts the load on the compressor (not from the pressure,
but the running time).

Usually, any in-built pressure gauges are wildly inaccurate -
best used as a rough guide only.

I've got 12V solar power in my back yard, and made up a long
extension lead. As others have mentioned, they can draw 10 to
20 amps or more. The faster the inflation time, the greater
the current draw.

I've been using a cheap 12vdc plasticky unit for years. It has been tossed

around, and I've replaced the nozzle twice with an alternate. No probs
getting to 75psi, however if from zero, then it stalls probably because of
overheating. then you can resume. I can run it off a basic cheap 4amp
240volt battery charger.

Ahh.. you've brought back some fun memories of chemistry classes..

Holding the power supply's circuit breakers open (or is it closed?)
while pencils turn into a very smokey mess or capacitors explode,
sending that little plastic bit flying around the class.
Those were the days! Ya know.. I don't even think anyone lost an eye! 😄

Only the $69 compressor has the current listed (23 amps).

Someone suggested I go to Jay Car and buy a 240V power supply which has room
for the alligator clips? If it's not too expensive then thats an ok option.

Alternatively someone said I could get a 'portable 12v power supply' from
Super Cheap Auto to power the compressor.

I will probably go for the $39 compressor as it looks like it is constructed
better.

I figured I could use a small air compressor on the car, bike, etc. The
power issues is not the end of the world, just a minor inconvenience.

I think I will go with the $39 compressor which they say is on sale from $60
or so.

It looks like it is constructed of some sort of metal rather than plastic.

I need at least 100 PSI for my MTB tyres.

Why get a compressor?

Silca track pump for ~$70. Doesn't require power (save the planet),
doesn't require all the [censored] to get the power (yay, light and
compact-ish), will almost certainly last longer than any compressor
(some people have said 20-30 years?!?).

What's wrong with the occasional servo fill?

Nothing *really*.

But there are a few issues:

- Half the time the servo pump is out of order.
- It's best to check tyre pressure when the tyre is cold.
- Convenience of regularly checking tyre pressure (esp. for cars).
- At the end of the day, the air compressor is cheaper (might not last as
long though as you said).
