I was soooo excited to find this. All the generic ones I could find only had the larger plug. The brand name one was twice as much money. I just couldn’t swallow that for a truck that’s a few years old and who knows how long it will last. This works perfectly for our small plug, but if you have the large one it also comes with the adapter for that. It has the indicator light and basically in every way is like the original. Except this works and my original doesn’t. The boys were sooooo excited to have their fire truck back on the road. I highly recommend this.
