accessories » Battery connections for tyre pump?

I routinely carry one of these tyre inflators in my top case: https://www.amazon.co.uk/dp/B07RSC13TZ
My previous bike, an R1200RS, had an aftermarket 'cigarette lighter' socket fitted in the fairing, so I could simply plug the pump in there to use, however it's dawned on me that my new R1250RS has no such socket, so currently the pump is about as much use to me as a chocolate teapot. I need to change the connections.

The battery on my current bike is fitted with the standard fused 'pigtail' cable for an Optimate trickle charger. I was wondering, could I simply replace the cigarette lighter plug with the same plug as on the Optimate? Would that plug/cable be OK current-wise? It would be a much easier solution that fitting croc clips (particularly bearing in mind that you'd then need to unscrew a cover to access the battery terminals, to use the pump).

That pig tail will power anything you care to plug into it. Heated jackets, pumps etc. Electricity doesn’t much care which way it flows among a piece of wire. Provided you don’t overload it, you should be fine.

If it helps. I have fitted cigarette lighter socket and just left it laying under the passenger seat. Works for me.

Yep. I use the pigtail for everything…so long as the draw won’t be more than 10A. However, the capacity of a motorcycle battery is fairly low. I’d run the motor while using the pump to prevent draining the battery too much.

I use a Fuzeblock to give me a mix of Ignition fed and direct fed pigtails for charger, pump and heated vest.

With spare capacity.

My “devices” came with different plug connectors, hence the need for multiple outlets.

I’ve inflated flat punctures, but did give the pump a rest along the way to 40 psi. My pump says 8 minutes is the limit. It’s not really, but it does get hot. Never run the bike while doing this.

I find it best to simply have a single Big connection to the battery. Gets a bit crowded in there if you try to add more.

I’ve never used the OEM socket, though I do carry a plug and USB adapter should I ever need to use my phone, but it’s a nuisance that the Canbus trips the socket after a short time.
(I carry a small USB “brick” when touring)

I use a 15A fuse in my SAE battery lead to handle any start-up current surge. According to the manufacturer of my pump, Rock Creek Designs, the typical current draw will be 8 to 11A, but the fuse should be selected to handle the start-up surge.

What can I say, I'm following the advice of an Australian company. They could have told me to install Roo bars. But, then I would have been banished to the R1200GS forum..............
