I use this style of battery, NP, on a studio light where I don't have easy access to AC power. This battery is built well and works quite well. I can also use it as a battery bank in an emergency. I like the percentage readout to know how much is left. It charged relatively quickly on a high-wattage power supply. It's easy to use as it is pretty much plug-and-play. It has plenty of power for what I need. I'm likely to get a second one as a backup.

100% recommended.

This is a very well executed, PD-capable battery that works equally well as a camera power solution and as a general-purpose USB-C power bank. The build quality is excellent, and it feels like a serious, professional accessory rather than a budget compromise.

What stands out

PD fast charging support: The 45W USB-C PD capability makes it suitable for modern cameras, monitors, and LED lights, as well as phones and other devices.

Dual-purpose versatility: Functions both as an NP-F970 style battery and as a standalone USB-C power source, which is extremely useful in the field.

Solid construction: Feels robust and well made, with tight tolerances and a premium finish.

Practical capacity: The 10,500mAh capacity strikes a good balance between runtime and portability.

Broad compatibility: Works well with a wide range of cameras and accessories from multiple brands.

Final thoughts
This is a thoughtfully designed, high-quality battery that adds real flexibility to a camera or video kit. Whether powering a camera, monitor, light, or charging devices over USB-C, it performs reliably and efficiently. A strong addition to any modern photo or video setup.

This battery has extra long battery life, it lasts way longer than I expected, even with heavy use. It charges quickly and stays powered throughout my shoots and outdoor projects, which has been a huge relief. I love that it has multiple plug-in options, making it incredibly versatile for charging different devices. Despite its power, it’s compact and fits easily in the palm of my hand, which makes it very convenient to carry. The build feels solid and reliable, and the USB-C fast charging is a nice bonus. Overall, a fantastic power solution that I use all the time!

this is supper cool, shows how many watts are being pulled, its small and light and works as it should, I totally recommend this, its amazing, battery life lasts long, functions as it should, durable and works with anything

This is an overall excellent battery for extending use time in a variety of devices. It worked perfectly with my field monitor (albeit somewhat bulky coming off the back) and was able to recharge my nearly dead iPad battery to 100% and still hadn't run out of juice. The USB-C output(s) make it pretty convenient to have around for a lot of modern devices, and K&F have been fairly reliable when it comes to camera accessories, so I have no concerns about it holding up. The limitation, though, is that F970 is not as popular as v-mount and not nearly as versatile. I may use this periodically for powering my monitor and a fill light but most likely it will stay around home acting as a power bank.

Hands down the best NP-F970 battery I've had. Awesome battery life, charges fast and easy with USBC, and can charge other deivces with USBC as well! Came in clutch yesterday when I forgot all my camera batteries, but was able to charge the K&F camera battery with this NP-F970 battery! Seriously saved the day. LOVE IT! I'll be getting more! 10 Stars!

I picked this K&F Concept battery up to power my Feelworld 7in field monitor and it has been an absolute beast. Running out of power in the middle of a shoot is a major headache, but this 10500mAh unit solves that problem completely.

⚡ The capacity is honestly great. I used it on a field monitor for an entire weekend of shooting and didn't have to recharge it even once. It just kept going. For a long event or a busy weekend project, having that kind of peace of mind is worth every penny.

⚡ I really appreciate the 45W PD fast charging. It means i can top it off quickly if I do need to, and having that USB-C port makes it super convenient to charge without needing a bulky specialized plate. It feels like a modern solution compared to the older NP-F batteries i have lying around.

The Verdict
This is a fantastic power solution for anyone using NP-F gear. The massive capacity and modern USB-C charging make it an easy recommendation for long shoots.

★★★★★ (5 Stars): "A 5 star rating indicates the product meets my expectations for its purpose."

Really surprised at just how good this battery is...love the readout on the top of the battery telling me how much charge is left and is essential for my use on a camera.

Charge times relatively quick with a fast charger and overall seems to work flawlessly on my camera.

The battery is excellent, with an acceptable weight (considering its size). It has a long life. I use it on a Feelworld monitor paired with a Sony A7iii and I have had no problems. The seller was very kind (even a little too kind, considering the times we live in). I highly recommend it!!!

As always, this product from the camera accessory expert is absolutely top-notch.

My personal highlight is the display showing the output power.

This makes it easy to see how much energy the connected device is consuming.

Of course, this also means you can estimate the approximate remaining battery life.

The touchscreen is nice, but a physical button would have been perfectly fine for me.

This camera accessory is clearly aimed at ambitious users and is by no means an entry-level product, but rather a professional accessory.

This is also clearly reflected in the product's quality.

For me, this product is a complete success and even comes with a high-quality USB-C cable.
