The problem with NVG and all the battery operated stuff is that once it runs out its useless unless you have a means to replace them through looting replacable batteries or recharging lithiums with an offgrid power system and the electrical knowledge to make sure you dont cook them in case of a jerry rigged system. It might be really useful for a good couple hours of operation but after that it becomes dead weight you spend calories or fuel hauling around with the faint hope of maybe being able to recharge it again sometime in the future
Realistically, everything is finite use if you can’t maintain it. The more relevant approach is what kind of utility do you get during that thing’s lifetime, and does it outweigh the other options. NVGs, while not my choice, do provide a lot of utility, and last a fairly long time. They also don’t run the risk of full-on breaking, just running dry, meaning that they can be kept around if you think you may find batteries.
