By Joe Gresh<\/h6>\n

Everyone has their kink. It may be guns, it may be watches, it may be old two-stroke motorcycles. I have a sweet spot for tire inflators. I must have 10 of the things, some are big and run off 240volt AC, some are so tiny they would fit inside a pack of cigarettes (if you smoked large cigarettes). Each inflator serves a specific need for me called “feeding my ego.”<\/p>\n

13 minutes from flat to driving. That’s fast for these type of pumps.<\/figcaption><\/figure>\n

My latest inflator, the GSPSCN, is a real beast. Sporting dual heads (I wonder if one might be a dummy head?) this little unit moves some air. Connected to a car battery, the GSPSCN can inflate a giant tractor tire from zero to 20 psi in 13 minutes 6 seconds. And that’s not the impressive part.\u00a0 The impressive part is the pump stays cool over that long stretch. All, and I mean all, of my other 12-volt inflators get hot as hell filling up a standard car tire.<\/p>\n

a nice, tidy little unit that moves lots of air.<\/figcaption><\/figure>\n

Until the GSPSCN I figured that heating up was the nature of small compressors. I haven’t dismantled the pump because I don’t want to break anything but I suspect there are diaphragms instead of pistons used in the two, shallow-finned cylinders.<\/p>\n

I’ve filled this tire dozens of times and the pump has not even gotten warm. The hose is a different matter.<\/figcaption><\/figure>\n

I’ve used the GSPSCN a bunch because the tractor has a not-so-slow leak in the left rear tire. Overnight it leaks down to zero, only the stiffness of the sidewall keeps the tractor sitting somewhat level.<\/p>\n

A more useless gauge I’ve never seen. I’ll index it one day when I run out of things to do.<\/figcaption><\/figure>\n

Of course this wouldn’t be an ExNotes review if we didn’t find something to complain about. The biggest issue is the pressure gauge. The thing is way, way off: like 9-10 psi. It’s useless as delivered. That means you have to have a regular tire gauge to know the tire pressure. It’s a small thing but annoying. Now I need two tools to fill a tire. One day I’ll sit down and mark the dial with a few numbers: 20-30-40-50 psi. Why didn’t the manufacturer do that for me?<\/p>\n

The power cord could be 5-6 feet longer. I can reach from the battery to all the tires on a Jeep but Jeeps are short. If you have a car, it would be OK. If you drive one of those big-ass, compensation trucks you’ll come up short yet again. The pump came with a coiled hose extension, but I would rather have a longer cord. Again, the extension is another thing to carry.<\/p>\n

The air chuck is a screw type, like all these small compressors I would prefer a 90-degree quick connect style. On a motorcycle with two big disc brakes, it’s hard to get your hand in there to screw on the chuck.<\/p>\n

Despite the above listed flaws. the GSP has become the pump I grab first for cars, trucks and tractors. The thing runs so cool I suspect it will last a while, unlike the hot ones that fail filling one tractor tire.<\/p>\n

I give the GSP a 4-star rating. If the gauge worked, I’d bump it to 5-stars. Go to Amazon and search the brand name if you’d like one.<\/p>\n
