K&F 50Wh V-mount battery 3400mAh, 65W PD Type-C fast charging, with TFT screen, D-TAP, BP, T

A 50 Wh V-mount power block with a colour TFT display. It charges over USB-C at 45 W and delivers up to 65 W, so it will run a camera, a light or a laptop.

• 50 Wh (14.8 V, 3400 mAh) — a 60 W COB light for 40 to 50 minutes, an iPhone 15/16 Pro Max twice
• USB-C PD3.0: 45 W input, 65 W output
• Two 16.8 V D-Tap ports, USB-A, a DC 12 V output and a BP electrode
• Colour TFT display with the charge level and an emergency night light
• Dimensions 108 × 76.5 × 38.9 mm, weight 350 g

50 Wh (14.8 V, 3400 mAh) is enough, the maker says, for 40 to 50 minutes of a 60 W COB light, two charges of an iPhone 15 or 16 Pro Max, 0.8 charges of an iPad Pro 12.9" or 0.6 charges of a MacBook Pro 14".

The USB-C port works both ways to PD3.0: it charges the block at 45 W and delivers up to 65 W. Beside it sit two 16.8 V D-Tap ports, a USB-A output, a DC 12 V output rated at 3 A and a BP electrode with a 16.8 V / 2.5 A input and a 16.8 V / 8 A output. A parallel circuit lets several devices run at once.

A colour TFT display shows the state, and there is an emergency night light and a BMS protecting against overheating, over-voltage, over-discharge, over-current, over-charge and short circuit. The block measures 108 × 76.5 × 38.9 mm and weighs 350 grams, so it sits in one hand.
