After taking off cap, place the air device firmly on your tire plug and snap dog the metal bar to hold it firmly in place then push the on button. when your bike tire is inflated to your satisfaction turn off device put cap back on immediately.
Question:	Does it have straw to reach hard to get places
Answer:	The box says up to 150psi if that helps at all...

User questions & answers

Question:	Can it used to clean dust from between the keyboard of my laptop without damaging it
Answer:	I use it for my tower fan. Seems to be no problem. As k me again next year at end of summer.
Question:	does it include the little straw looking thing that you can put on the tip
Answer:	The item that I received is indeed the Falcon Compressed Gas as noted in the item photo. I have used Falcon Compressed Gas several times in the past and I have found it to be an excellent air cleaner for computer and other purposes.
Question:	it contains a "bitter ant" huh? didn't know ants could be bitter
Answer:	Yes, each can comes with a thin, red straw to attach to the nozzle, which is very handy, of course (standard for these kind of things).
Question:	Will this affect acryllic or oil paint
Answer:	Yes! If you fill all the balloons and then let them out of your 2nd story or higher window, they will float ever so gently down to the ground. This air is super light but just a tad heavier than helium, that is why they will not float UP. The best use for this canned air is actually to use it in the bathroom after brushing your teeth. Open your mouth and blow it all over the inside of your cheeks and teeth. Your mouth will be dust free in no time! Don't worry though, you won't begin to float.

User questions & answers

Question:	Can I use this to clean out pilot assembly on propane heater
Answer:	It's because it's not actually compressed air it's actually just HFC-134a in a liquid form but under pressure it changes it to a gas when you turn it sideways/tilt it or upside down the liquid refrigerant HFC-134a comes out and is dispensed!

User questions & answers

Question:	Does this include prime shipping? the search result says this has prime shipping, but the product page doesn’t mention it
Answer:	A National chain store sells a 10oz can for $2.38 with a $35.00 purchase. The Prime price probably takes into account weight and shipping costs. Personally, it doesn't seem that Amazon or some individual sellers can compete with chain store pricing when it comes to sprays, liquid, paste, or food. Perhaps, someday, the playing field will be more level.
Question:	is there difluorethane in this product
Answer:	Yes, it can work without damaging the keyboard.

User questions & answers

Question:	Can it be used to get bugs out of devices
Answer:	The XPOWER A-2 bottom filter can be washed with mild detergent and air-dried for continued used.
Question:	Does the canned air smell like corn or anything else odd? I recently bought a different brand and hated the smell
Answer:	This will work, but I would hold your figures or statues to make sure they won't fly off the shelf. This thing packs quite a punch as far as the air it pumps out. It does have a low and high setting and depending on the attachment you use, will vary the air flow that comes out. But you should probably never directly blast something without it being secured in some way just to avoid any kind of accidental damage.
Question:	Do these come with the straw
Answer:	That is absolutely not true (I'm an electrical engineer and an IEEE Senior Member, and I have been building my own PCs for 25+ years). Leave your PC plugged in so that your case is grounded while it's open. When blowing, don't try to spin the fans ridiculously fast; their bearings aren't meant to take the speed, nor can they take the lateral force if you blow sideways from up close. You are blowing out dust, not sandblasting, so direct a stream from about 18 inches away. I like to "pulse" the air stream, same as I did with canned air. But instead of pressing a trigger on and off, I move the blower back and forth. If you are concerned about dust that is sticking to fan blades, use a damp cotton swab (there are special long-sticked ones made just for electronics) to gently "brush" the buildup off; this is tedious work, but it's safe and effective. Of course, you probably can't get into your power supply fan with this method.
Question:	Do these cans each come with a thin straw, used to blow into tiny spaces
Answer:	This product can only be sent ground, we are unable to ship overnight.

User questions & answers

Question:	When dusting, should air be coming out of the vertical slits on the side? Airflow is stronger from there than from the nozzle itself
Answer:	Assembled in USA using both domestic and imported components
Question:	Mine is working properly, however, I plugged it in overnight and in the morning the yellow light was still on. Why does the light not go off
Answer:	If you mean in a box that doesn't have the "canned air" brand name on it...no, it comes in a box that in no way indicates what is inside. I ordered 8 cans and they were divided in two separate boxes. Due to the weight and the movement of the liquid gas in the cans, they were quite unlike most boxes you receive. I felt the shipping boxes needed heavier duty boxing because they were a bit squishy by the time received.
Question:	How loud is it
Answer:	It all depends to how and on what you use it for I live on 5 acres and its windy most of the time nothing to block wind and dust so I use it on my PC and 2 TV,s I use it on the inside through holes units have to blow out dust about once a week and a can lasts me for just about 2 weeks.
Question:	What is the CFM of airflow
Answer:	To attach the straw adapter with the detail brush onto the A-2, you would use the tapered flow nozzle and then proceed to push the straw adapter into the tapered flow nozzle as firmly as possible. Proceed to turn the A-2 on low while pushing the nozzle and then turn on the high setting. This should ensure the straw adapter with the detail brush stays on even at the highest power mode. You can find a guide to all the nozzle names in the offical A-2 manual. http://www.xpower.com/wp-content/online-library/owners-manuals/A-2-Owners-Manual.pdf
