K&F CONCEPT NP-F970 touch screen display direct charging battery, 10500mAh large capacity

A power block on a Sony NP-F mount with 10.500 mAh and an OLED touch screen that shows the charge in per cent at a tap.

• 10.500 mAh (7.4 V, 77.77 Wh) — monitor 5.8 h, camera 6.7 h, LED panel 4.5 h
• OLED touch screen with the charge level in per cent
• USB-C both ways, PD3.0, QC3.0, QC2.0, FCP, AFC and PPS protocols
• The NP-F mount fits cameras, lights, monitors and motorised sliders
• Protection against overheating, over-voltage, over-discharge, over-current, over-charge and short circuit

10.500 mAh at 7.4 V works out at 77.77 Wh. How long that lasts depends on the load: a 14 W monitor runs 5.8 hours, a camera in 120p video mode (10 W) 6.7 hours and a 15 W LED panel 4.5 hours.

An OLED touch screen shows the charge — a tap on the button is enough. The USB-C port works both ways and speaks the usual fast-charge protocols PD3.0, QC3.0, QC2.0, FCP, AFC and PPS, so the block charges from whatever is at hand.

The NP-F mount matches Sony’s own batteries, so the block fits cameras, LED lights, monitors and motorised sliders. The electronics watch overheating, over-voltage, over-discharge, over-current, over-charge and short circuit.
