I confirmed operation with two panels! Two batteries. You can use it with one battery attached to each panel! It lights up in two colors: white and cloudy yellow! The adapter is not fully charged. The adapter may not be the standard one. I was charging it as is, since it can be charged and used! Everything in the pictures is included. Since I am an amateur, there may be scratches, etc. Thank you for your understanding! I will not accept any claims! Thank you! Please check the images carefully!!
