If you can make a dynamo, you can make a motor. Now, you aren’t about to create Tesla. But there’s plenty of things back in the day that could benefit from being motorized.
Could you also do ac/dc conversion to make the electricity useful elsewhere? I’m guessing charging and transporting primitive batteries won’t be able to fulfill any useful purpose at all.

Also making carbon Zink batteries should be possible, so a handheld fan would definitely be a possibility and would already be mind blowing
