I’ve been using this big NP-F style battery for about six weeks now, mostly to power an LED light panel and occasionally a field monitor. The best part about it is the little screen on top. Usually with these types of batteries, you just have to guess how much juice is left, but this one actually tells you the percentage when you tap it. It feels a lot more high-tech than the other ones that just have those tiny green dots.
I actually ended up using it as a backup charger for my tablet during a power outage last week. It has a USB-C port that puts out a lot of power, so it charged my iPad way faster than I expected for a camera battery. When it finally died, I used my laptop charger to fill it back up, and it was done in less than four hours. That is way better than the old style chargers where you have to slide the battery into a wall cradle and wait forever.
The only real issue I had is that it’s quite a bit taller and heavier than the standard Sony batteries. It didn't fit in the battery compartment of my older camcorder because the door wouldnt close over it. Make sure you have enough clearance if your battery slot has a lid! Also, the touchscreen button is super sensitive, so the screen kept turning on in my bag when it bumped against my lenses. Other than that, it’s been a really reliable way to keep my lights running during long shoots.

The K&F CONCEPT NP-F970 10,500 mAh battery has proven to be a true game-changer for my video setup, finally solving the battery life issue during longer shoots. Despite its enormous capacity, the design remains compact and well-made, with a build quality that conveys solidity and professional reliability right out of the box.
The real plus of this model is the built-in USB-C port with 45W PD fast charging. I'm really enjoying it because I'm no longer tied to bulky external chargers: I can quickly charge it with the same power supply as my laptop or smartphone, and if necessary, use it as a powerful power bank to power other devices.
Here are the reasons why I consider it an excellent purchase:
Infinite Battery Life: The 10,500 mAh battery guarantees incredible battery life for field monitors, LED lights, or video cameras that use the NP-F standard, allowing me to work for hours without interruption.
Charging Speed: Thanks to Power Delivery (PD) support, charging times are dramatically reduced compared to standard batteries, a key feature for those with a busy schedule.
Total Versatility: The USB-C port makes it a highly useful hybrid accessory, eliminating the need to carry a thousand different cables in your backpack.
Value for Money: It's truly excellent, considering that the K&F CONCEPT offers performance and safety (overvoltage and short circuit protection) comparable to original batteries, but with additional smart features.
In conclusion, it's an essential accessory for any filmmaker or photographer looking for power, modernity, and practicality in a rugged package. It immediately became my main battery due to its reliability in the field.

The NP-F battery has become THE go-to battery in the video world since the late 80s, powering everything from cameras to accessories!
This 10500 mAh battery, rechargeable via USB-C, can also be used as a USB-A or USB-C power bank!
Unlike many other generic batteries, this one has a screen that lets you see its status and charge percentage at any time, which is incredibly convenient. There's nothing worse than realizing your battery's actual charge level after pressing the "record" button...
Not only does it have a substantial capacity, but its attractive design makes the original look outdated!
It remains to be seen how it performs over time, but for now, I'm quite happy with it and recommend it!

I've been using the K&F CONCEPT 10500mAh Battery in an adaptor plate that provides both D-Tap and USB outputs (clamped to the leg of my tripod) to power both my field monitor and Sony A6700 dummy battery quite happily. There is plenty of capacity available to power both for several hours!
The ribbed case of the battery not only looks distinct from other batteries, but also provides a better grip over its smooth cased competitors (very nice when wearing gloves). The glossy panel at the rear covers the OLED screen and has a capacitive touch switch where the K&F logo is to activate the screen. The glossy panel is very much a fingerprint magnet, but does wipe clean easily.
If mounted as a NP-F battery on my monitor, there are 2 USB C and 1 USB A outputs available, there is a 'rubber' cover over 1 each A & C sockets and the C type socket used to charge the battery also doubles as another output.
Total output is rated at 22.5W, and charging, using a PD adaptor at 45W. I'm not certain how rigidly the 22.5W output is applied, as I suspect that my camera and monitor may slightly exceed that draw when the monitor backlight is at maximum power.
I recently noticed that 'holding' the power button (logo) for a couple of seconds will switch the display to Watts, and show the total draw from the battery - nice!
If the battery is fully charged and not immediately used, it will self discharge at around 3% each week (assuming it is linear)
The inclusion of a plastic cover for the front of the battery, giving some protection to the terminals is, in my opinion, a practise that should be adopted by other brands, It just makes sense!
Happy to give it 5 stars, it's been doing soveriegn service for me in local woodland hoping to capture video of the local wildlife.
