That vest is the incorrect voltage to plug directly into a 12v system. If you want to plug into the bikes electrical supply, you need to get a 12v rated vest, or any other heated gear. You can charge the battery from the bike with the appropriate adapter, but that's it. I use an Iurek zd920 vest by supplied battery pack. Lasts almost 9hrs on a full charge on low. That's plenty of heat under a lined windproof shell(leather). I run my heated gloves via a temp troller hard wired to the battery with an in line fuse. No fear of overwhelming the electrical system like that. But you CAN get a dual zone controller (2 heated gear items at once) provided you do your research of amp/watts draw vs available amp/watts. output.In theory it should work. Your plug adapter has a max output of 36 watts, the battery pack maxes out at 22.5. The wildcard is not knowing what the vest input requirements are. If it requires 9v, you're adapter may be a little shy - it provides a max of 2 amps, the battery pack provides 2.22 amps. Is there a tag anywhere on the vest that lists technical details?
