    Can I use factory 12V power socket for a tire inflator (compressor)?

    I just bought a dewalt tire inflator.  It doesn't come with a battery or AC cord, but does have a cigarette plug.  Can I use the onboard 12V power socket without risk of blowing a fuse?  Does the engine have to be running?

    -- edit:
    I think the answer is no.  The manual says the socket is rated at 5 amps, and from googling it looks like a little inflator/compressor would potentially draw more than this.

    Your bike doesn't have fuses - overload protection is provided by the Canbus system which will simply disconnect the power from that circuit. Most mini compressors will draw too much current and power to the socket will indeed be shut down . Best advice is as above - fit a fused flylead direct to the battery to power the compressor. I also us the same flylead for connecting an Optimate conditioner to.

    A separate connection to the battery is definitely the way to go. Iíve heard of people test plugging into the onboard socket and watching the compression chug away happily and assuming all will be well when itís needed to inflate a tyre. However, when under load, pushing anything over about 10psi, the bike canbus will disconnect.

    The other way is to hardwire a fused connector into the battery with a fuse able to handle the mini pump.  That's what I do because I also use a Battery Minder charger.
