Podrobný popis

The K&F Concept KF-V99 V-mount battery with a capacity of 99 Wh (14.8 V, 6700 mAh) powers cameras, monitors, lights and laptops. It charges at 65 W over USB-C and delivers up to 65 W, plus USB-A, 2× D-Tap and BP contacts. An LED display shows the percentage, remaining time, voltage and USB port status. With a capacity under 100 Wh, the battery may travel in cabin baggage.

99 Wh capacity

A fully charged battery is good for roughly 7 h of Canon EOS R5 recording in 8K/30p, 5 charges of an iPhone 14 Pro Max, 3 charges of an iPad Pro 11" and 1 full charge of a MacBook Pro 16". The V-mount plate attaches it to cameras, cages and lights, and the 100 Wh limit lets you take it on a plane in hand luggage.

65 W USB-C in both directions

The USB-C port charges the battery and powers a laptop, tablet or phone. With an adapter of at least 65 W it is full in about 2–3 h. Next to it are USB-A, 2× D-Tap and BP contacts; the ports work in parallel, so several devices can run off the battery at once.

Protection and controls

A BMS looks after the cells, with protection against overheating, overvoltage, over-discharge, overcurrent, overcharging and short circuit. An LED display shows the percentage, remaining time, voltage and USB port status.
