Excellent Product. Works well with my A6300
Received product in 17 days. Product on a glance look the same as described but as soon as the camera shutter button is pressed, the camera stops responding unless I put back in the original batteries. The unit definitely is defected or not giving out enough power. I have tried with different Power USB Adapters/ Power Bricks (2A, 3A) as well as different Power Banks but still it isn't working.
BTW, my camera is Sony a6000 with Kit Lens. Doesn't work.
