This works!
This adapter really works. I no longer have to worry about those weak FW-50 batteries. Now, with all those power bricks available, you have all the power you need in your camera for extended periods.

Great solution for quickly dying batteries
I love this thing!!!! So for still, I primarily use batteries but for video, the batteries die really quickly. I can just. about shoot all day with this plugged into a portable battery pack.

Works Well
Works well using a Sony A6000 powered by a Celestron Powertank Pro external batter using 5V/2A USB output. A note on other comments: like some people, I noticed a quick drop in estimated power remaining when beginning; started at 99% and dropped about a percent per minute. But once it reached ~77% it just stayed there for hours - took thousands of photos, once every 15 seconds, for over 12 hours, monitor on, and it never dropped below 76% the entire time. I believe this is because of the way the Sony estimates power, using voltage; this is a tricky approach, Sony batteries typically begin a charge with ~7.5 volts and fall off to maybe 3 volts during use. The 5V USB output makes the camera think it's got a battery that's partially depleted, but there is still plenty of power to run the camera. The rapid drop was alarming at first, but it isn't something to worry about. I believe this is normal with USB-supplied power due to the "low" voltage the camera sees. ... show more

Unlimited power on ZV-e10
Perfectly powers my ZV-e10. Can use a USB battery pack and record for over 3 hours (with the camera on high temp). Tried this through the USB C port with the original battery and it fried the memory card. Not with this battery.

Breathed new life into my A7ii
None of my NP-FW50 batteries were lasting more than a half hour, especially in chilly weather. Just used this adapter yesterday with a 10,000 mAH Anker battery pack and the camera was still running strong after 7 hours. Pretty excited to finally have a way to set this camera up as a wildlife trap camera! ... show more
