    I suspect you don't use the BMW plug in the factory receptacle that is connected to the CANBUS, or do you? From what I have seen all of these devices exceed the 5A trigger, disabling the port and generating a fault code.

    I have been looking for a compatible inflator but I will likely settle for one with clips for the battery.

    What, you need a BMW plug or battery to inflate tires?

    I just rewired the end of my pump with the same fitting used for the trickle charger. I just plug it in and it works off the battery. no need for clips

    I run the pump off the factory 12V plug on my RT and have never had a CANBUS "blown fuse" issue

    I've have had this one from Harbor Freight going on 5 years now without a problem. Works every time and and it fits in the radio box storage area on my RT. And did I mention it's only $10 bucks!

    When I first bought my bike I used the inflator I keep in my car. It would work for several seconds then the CANBUS would interfere and disable both factory outlets, throwing a code in the computer. After cycling the key the computer would reset but the inflator would again, trip the outlets. Subsequent research showed the 5A limitation for the factory outlet, I have been looking for a compatible inflator since.

    Being that your bike is a 2007, do you know the maximum amp draw allowed for your outlets? Do you know the amp draw of the inflator you are using?

    Thanks in advance.

    Interesting, certainly looks tempting from the size/cost standpoint. Do you have the specs on amp draw for that unit?

    5A is the GS limit. The RT is reported to have a 10A limit. I don't have a copy of the RT manual on hand to verify.

    FWIW my cyclepump draws around 5A -- it will run from the accessory socket unloaded. When actually attached to a tire it starts pulling more than 5A. Glad I did my initial test by actually trying to put air in a tire.

    Now I feel a little silly, you are right about the RT and 10A limit. I just checked the owner?s manual and sure enough, 10A for "all" sockets. I am just not sure if that is in anyway divided between the two for 5A each.

    Now all I need to figure out is how the draw changes from unloaded to loaded i.e. pump running when not filling vs. running while filling.

    Any ideas on how this can be determined?

    I believe the sockets are in parallel, giving you a total of 10 amps in any configuration you like. If you are pulling 10A from one you've got nothing left over for the others.

    A good multimeter will let you measure current up to about 10 amps. The issue is that you have to break the circuit to put the ammeter in series with the load. In this case it's probably not worth the effort. Turn on bike. Plug in pump. Pump up tire. Did the bike turn off the outlet? If not you are under 10 A. Is the exact amount really important? I don't think it's too much of a hardship to turn off other electrical farkles during the 3-5 minutes it takes to pump up a tire.

    I use them all the time. Much more convenient for putting a couple lbs of air in your tires than a big compressor. Just hook it to a powerlet adapter, plug it in and you're set. Often gas station air compressors don't work or don't fit our wheels....so this allows us to inflate anywhere. I've used it on the side of an interstate as well, to get to the next ramp where the tire was flat again.

    I'd say the regular price is OK, but if you can, wait for a sale.

    Great idea Nancy. Thanks for sharing.
