NP-F550 Sony NP-F570 NP-F530 NP-F330 NP-F930 NP-F950 Batteries for CCD-RV100/RV200,SC5,Camera Battery Charger Set Sony TR1/TR11/1100E/12/18/18E/1E/2/200,V3000,HI8/DCM-M1, DCR-SC(3891x2pics,5.5hoursx2)

I really like the fact that this uses a Micro USB and not any other kind of weird port as it allows me to just stuff a lot of Micro USB cables in my bag with a universal standard. The reason why I chose this unit was that it allowed me to charge any other kind of NPF batteries without any problems, also I wanted a smaller battery so that when I am traveling it will help me reduce the weight on my backpack. I shoot with a lot of video lights and these were great when I paired it with the Yongnuo YN600 as that required 2 of the NPF batteries. These batteries deliver 24Wh @ 7.2V/3350mAh which is very optimal for my video shoots, I used this on a music video and they lasts me for the whole 2 hours of shooting, I believe these can last 3 hours on the Yongnuo YN600 at 50% power which is more than enough. Overall I am satisfied with the build quality and they serve me very well

The Oxker USB powered charger is a great compliment for my wall outlet only Neewer NP-F charger I was using. While the Neewer charges faster due to AC power, I needed something that would work on the go. The Oxker charger works fine so far with my Ravpower battery bank. On the battery side, it is hard to tell without extended usage but at 7.2v and 3350mAh (24.12Wh) they should run longer than my current DTSE NP-F batteries that are 7.4v and 2900mAh (21.5Wh). I shot some footage with these batteries in my Aputure Amaran AL-H198 lights and they seem to work fine. I will update this review as I wear in these batteries.

Nicely made product. Works fine.

Will not hold a charge ??? 30 minutes that alk. I charged them for 8 hrs
