Hello. I can't say what that can be, but I would try with other power supplies. 

These binoculars have night vision in low light conditions and can be used at night but not in total darkness. 

yes, however for added stability you should add counter weight at the bottom. 

No. I bought it based on the claim that it would support the weight, but it doesn't. However, i have found that if I don't try to use the cantilevered function, but just use the height of the combined tripod and arm (straight up) and the ball joint holding the binoculars, I have more than enough height to see anything up to about 75 degrees comfortably. In the video, the eyepieces are at 6', and there is easily another foot of extension available.
