Hey 

Anyone use a USB battery power bank/charger for the Samsung freestyle projector 

If so which one do you use please looking to get one just not sure on the best one.

I tried asking a Samsung person on Web chat he did not know lol.

Thanks 👍

I tried an 18V Ridgid tool battery with a USB cap, and it didn't work. Not sure why. Also tried a small power bank...same. If you are successful, please let me know.
