Has anyone used the adapter? After seeing how fast my camera batteries are used on my 5D MK IV, I noticed the adapter which can attach to a external USB battery pack, or be powered from AC using a USB power supply. It is not a charger, and has a potential failure mode due to the internal battery which could die, in fact it will, given time.
Its just something that's a alternative to a grip, and buying several batteries at $65 each. I tether my camera frequently, so having continuous power beats changing batteries frequently. I'm not a big fan of tether tools, but it appears that they have a viable solution here.
