I have a 48 volt 17.4 AH battery with a barrel connector charging port. Can I use this port as power output for temporary operation of small 48 volt tire compressor?

If this is not OK, then how should I set this up? My battery is a Dolphin pack with a female jack that connects when you lock the pack into the bike. My goal is to be able to add air to my fat bike tires while out on a ride, say coming off sandy beach going onto pavement.....

Thanks in advance for any advice.
 
Yes. I have tried it and it works. The charge port can't handle a lot of current, but the pump takes less than 2A. There is no protection for low battery or over current using that port, but it shouldn't be a problem for the amount of time it takes to pump a tire.
 
Thanks!

So I will just make sure and put a fuse inline with the jack I plug in so as to have over current protection.
