Vemico NP-F970 Battery Charger Kit 2x8500mAh Replacement NP-F550 Batteries with LCD USB-C Charger for NP F970/F960/F530/F550/F570/F730/F750/F770/F930/F950 (8500mAh)

I tested it with several different cameras. The battery took 9 hours to charge with the stock charger which is recommended for all new batteries before use no matter what brand they are. Upon removing it from the charger I placed the battery in one of my cameras. So the verdict for all the cameras I tested it on fully charged after each use:At 4096 × 2160 full frame, 256∶135 I got 4 hours and 3 minutes of use with the battery.At 3996 × 2160 flat crop, 1.85∶1 I got 5 hours 53 minutes of useAnd finally at 4096 × 1716 CinemaScope crop I got 4 hours and 29 minutes of use out of it.These times are very acceptable and almost, almost on par with the official batteries.The orange coloring is very nice and easy to see, it also made it easy to find when I lost the battery in my large camera bag.I'd say the batteries are very acceptable.

I’m really surprised at how nice this whole package is! The batteries work well.Charger died after a year of use.

I like that I know who's these are on set.I like that they stand out.I DO wish they were the full 8800mAH you see from the competition. 4 stars because... If the competition can do it...Charger seems to work great and not get hot. Batteries do their job (funny how NPF batteries have been around since I was a child) and I really enjoy the pop color when compared to my all-black video gear.

Las uso para una lámpara de 200 leds la cual utilizo a lo largo de una hora para videos y aun me sobra batería utilizando sólo una, el cargador es super práctico ya que puedes cargarla ambas ya sea en el carro o la casa ya que puedes conectarlo al cargador de tu movil

Same as others have said. I bought the larger batteries with double charger a year ago. The charger arrived with only side working and then it stop charging completely. Please fix these chargers.

I love that these batteries came in a convenient carry case to keep everything organized. I got these to help power my external video monitor and my black magic pocket camera, they do a great job powering them especially for their small form factor. They run my monitor all day! I also really like that the dual charger is USB-C and can power it from a wall plug, my car, or a battery bank!

The media could not be loaded.  I have many LED lights that require these Sony NP-F style batteries as it is pretty much a standard. I also have many of these NP-F batteries as well to run my lights... I try to have at least one set (or battery) per light I own (though I don't use them all at once obviously). These Vemico batteries are pretty good quality and I love the fact that they are ORANGE in color (others are black) so you can find them easily in a black camera bag. The charger works great and comes with a USB-C charging cable. Actual USB wall charger itself is not included so you should get one if you don't already have any laying around. To get the best charge you should use AC power (wall jack) to charge the batteries for best/fastest results... Using a USB battery pack type charger will work in a bind but will not work like being plugged into a wall... This goes for properly charging any battery for the most part... I will be purchasing more of these Vemico batteries in the future...

Have used with a wireless display and a ring light that uses the same batteries. Seems to work good
