air pump

[Goldfinger]

We are going round in circles, everyone knows that by connecting directly to the battery just about any pump can be used.

What a lot of us would like is a pump that can be used reliably just by plugging into the power socket the bike came with.

Surely that is possible?

Motopressor pump I bought at NEC last year - (see them on Nippy Normans) brilliant ! light, compact, strong, no stupid plastic case to break. Used it twice for puncture repairs on tour (safety seal)
not as cheap as some but i reckon great quality.

The power socket the bikes comes with is in a really handy place for rear wheel punctures - which account for 9 out of 10 flats, if not more.

 

[Goldfinger]

Not much we can do about the location of the power socket. I can't see it being a problem provided the leads on the pump are long enough to reach both tyres or the tyres on a bike parked alongside yours, if your helping someone else out.

AIR PUMP COMPARISON

Hi Ian;

I put together the comparison chart below:


MICRO POR INFLATOR MINI PRO INFLATOR GT
Max Pressure 100PSI/6.84BAR 50PSI/3.5kg/cm²
Flow Rate 0.68cfm @ 0PSI/BAR 0.50cfm @0psi/14lpm@0psi
Weight 7oz/198g 18.2oz/516g
Air Outlet Zero Loss Inflation Connector Zero Loss Inflation Connector
Additional Fittings Sports Inflator Tips
Inflation Rate 3 minutes, 100/90-19 front tire, 0-36psi 7 minutes, 195/60/R15
5 minutes, 150/70-17 rear tire, 0-36psi
Run Duration 30 minutes/20 minutes cool down time 30 minutes/20 minutes cool down time
Max Current 4.5AMP @ 40psi 6amp
Voltage 12.0VDC - 14.8VDC 12VDC
Power 55W @ 40psi 72W
Motor Geared, fan cooled Geared, fan cooled
Noise 69 db 69 db
Dimensions 3.9”X3.62”X1.57”/99X93X40mm 4.75"x6"x2"/120x150x50mm
Power Cord Up to 9.8’/3.0m Up to 9.8’/3.0m
Air Hose Length 1.6’/500mm 3.25'/1.0m
Certifications CE, RoHS, ISO 9001 Factory CE, RoHS, TUV Factory

The MICRO POR INFLATOR is a newer product, about half the size, a third of the weight that can attain double the pressure. All this using less power (current) that allows it to be connected to BMW's motorcycle cigarrete lighter outlet allowing you to inflate your tires without triping the boke's protection circuit.

They both do the same, however the newer MICRO POR INFLATOR will do it quite more efficiently under all aspects,

Hi Andre,
Is there a link to purchase them in the U.K.?

The man's in Brazil.........why can't you do a search for UK stockists?

Cos all I can find is places like Amazon doing it for 65 quid! Thought as he works for the company he might know an importer who sells them at a more realistic price. Sorry for asking!

No trouble but sorry I can't help you out...

5 minutes, 150/70-17 rear tire, 0-36psi
Run Duration 30 minutes/20 minutes cool down time 30 minutes/20 minutes cool down time
Max Current 4.5AMP @ 40psi 6amp
Voltage 12.0VDC - 14.8VDC 12VDC
Power 55W @ 40psi 72W

So if the canbus governed 12v bike socket can only work at a max of 5amps, it looks as though it will have tripped out before the tyre reaches 40psi when the pump will be asking for 6amps?

Or am I wrong?

Has anyone tried one of these pumps up to say 45psi?

 

[GORILA]

If you run your engine whilst operating the air pump, the Canbus shouldn't trip your devise. I use my pump this way with my Hexhead and have no problems with inflating/ mounting tyres. Running the engine also gives the pump a little more power too !

When I copied and pasted the table above it lost its format and all texts become a bit confused... Sorry about that.

Anyway, the figure of 4,5 amp refers to the Micro Pro Inflator while the 6 amp figure refers to the Mini Pro Inflator model.

Ah that sounds much better! Thanks for clearing it up.

 

[ATG]

The bike's computer, not the CANbus, will shut the cigarrete lighter output anytime its output exceeds 5 amps irrespective if the engine is running or not, True that when the engine is running, the system runs up to some 14.3 volts and while on battery power alone, as when the engine is off and, therefore, the alternator is not generating power, the system voltage with a fully charged battery runs at some 12,2 volts.

As every time there is a voltage drop there is, up to a point, a current increase as equipment consumes power and power is the result of voltage X current, thus, up to a point, when voltage drops current tends to go up.
