Compatibility

Retailer reviews
Summarized retailer review data when available.
This is NOT compatible with the trains, which is quite unfortunate as those burn through batteries fast. It would have been nice if the product detail explained what this worked with.
While the product description says "plug this into the LEGO Hub, that Hub is specifically the one that comes with the e-Performance technic cars, product 42167 and 42171. For those particular sets, these are great to have on hand if you play with them a lot. I wish LEGO would make something similar for the 88009 Hub so I could charge my trains instead of burning through dozens of AAA batteries every Holiday Season when all my trains are running.
