K&F Concept 10500mAh NP-F970 Battery for Sony NP-F970 F960 F950 F930 F550 F570 F750, with USB-C Fast Charging, Replacement Battery for Camcorders, Monitors, LED Video Lights
From the brand
USB-C rechargeable NP-F type batteries aren’t a new concept at all but I think these push it a notch further. This battery has an USB-C port that does 20W input or output, and a USB-A port that does about 10W output. Both USB ports can be used at the same time, and as output (such as when used as a power bank) the USB-C port will drop to about 15W. All this is possible also while the battery is plugged in to a NP-F interface!
So although the price is a little steep; there are definitely cheaper options out there, this K&F one is a really solid choice and doesn’t seem to self-discharge at too much of a rapid rate. 20W PD is also really convenient and ensures that the battery can be charged at a decent speed, even if it won’t be the highest speed out there for similar products.
Overall, more expensive than other less well-recognized brands but an excellent choice for powering your lights and accessories, as well as use as a power bank.
This K&F Concept NP-F970 battery has a capacity of 10.5Ah and just plugs into any compatible device. On the top are a series of lights and a button such that you can tell the current charge status of the battery when pressing the button.
Normally, these units are charged by putting them into a charger which derives its power from a USB A plug which, by its nature, is a little more limited than USB C’s power capacity. Whilst you can charge it with a normal charger that you slot them battery into, this one also has the capability of charging it with a USB C socket that is mounted on the end of the unit. This then has the ability to recharge substantially faster than the other method.
Additionally, this also has a USB A socket mounted in the opposite end to the USB C socket and you can use this to charge up something else so you can also use this as a power bank if you need to.
These batteries are very useful to have around as they can be used for running LED lighting units upto around the 60 watt mark (usually paired) as an alternative to using a D-Tap block.
This product was sent to me to review, as part of Amazon Vine. Below is my own real-world experience of using it.
I don’t have a Sony camcorder, however, this particular battery is extremely adaptable to other equipment (field monitors, video lights, etc.), so that was actually the purpose of my request for the device.
The build quality is excellent – it has a robust feel, with weight you would expect compared to either the original article, or a similar third-party item. It also has a sleek finish, with neatly-sealed connection ports – the rubber ‘doors’ fit securely and provide protection from dust/moisture.
I have tested it in a number of different scenarios – firstly, using a dummy battery and adapting plate, which were then connected to my Panasonic G80. The camera had a consistent power supply throughout, and functioned normally. I then used the included USB-C cable to charge my iPhone 15 Pro Max with the battery, which also worked well. I am certain there are probably many more cameras and accessories that could be compatible with it – it’s extremely versatile.
So far, I have found the overall battery life to be exceptional, whilst it’s straightforward to recharge, and this could even be done by using a power bank – great for portability. On the top of the battery, there is a helpful button that allows you to check its remaining capacity, whether in use or not, too.
In summary, a good value item that is a useful addition to any photographer’s/videographer’s kit. Highly recommended.
This works great and is really good quality. It’s a portable charger that can be used on other things, not just the Sony brand. The battery lasts a long time and charges items quickly
Nice battery, works perfectly and lasts a long time. I have many NP batteries and other batteries of these dimensions, are only 7800 mAh, so if this is in fact 30% larger capacity, its a super value. I have no way of scientifically testing, but I am very happy with this battery as it ran my BMPCC6K for a few hours on a hot summer day.
I am a fan of K&F Concept products, every one I have bought has been very high quality
