SMALLRIG V Mount Battery VB99 Pro 99Wh - Compact HighPower V Mount

In this review the SMALLRIG V Mount Battery VB99 Pro shows itself as a compact, versatile power solution for run-and-gun shooters and monitor users who need a reliable V mount under the 100Wh TSA limit. The single biggest reason to buy is its balance of size and output: at 99Wh with bi-directional PD 100W charging and multiple output ports, it fits airline carry-on rules while powering cameras, monitors, laptops and lights without carrying larger, heavier batteries.

Key Features

• Bi-directional PD 100W: Two USB-C ports support PD 3.0 and can deliver up to 100W for fast charging devices or charging the battery itself via USB-C1 for a full charge in about 2.5 hours when paired with a 100W GaN charger.
• Multiple interfaces: The VB99 Pro includes 2 USB-C, USB-A, DC 8V, DC 12V, BP and D-TAP ports to run cameras, monitors, lights, phones and laptops without adapters.
• Compact footprint: At roughly 4.2 x 2.9 x 2.2 in and 23.3 oz, it packs 6800mAh into a palm-size V mount that is easier to carry than many larger V batteries.
• Smart display: A bright digital screen provides real-time readouts of port status, voltage, power output and remaining battery life so users can monitor runtime accurately on set.
• Safety and certifications: An intelligent BMS protects against short circuit, over-temperature, over-voltage, over-current, over-charge and over-discharge, and the pack is certified to common safety standards.
• Mounting flexibility: The rear V-mount plate has 1/4-20 and 3/8-16 threaded holes so the battery can be secured with ball heads or clamps in tight rig setups.

Who It's For

The VB99 Pro is aimed at video shooters, content creators and on-the-go filmmakers who need a flight-friendly V mount battery that still delivers strong outputs for cameras, external monitors and USB-C devices. It is particularly useful for users of mirrorless cameras and compact rigs who want to power both camera and accessories while keeping weight down.

This is less suitable for crews who require extremely long runtimes from a single pack or those running very high-draw cinema monitors and accessories for multi-day shoots; heavier V mount packs with larger capacities would be a better fit for extended location work.

Pros & Cons

Pros

• High 100W PD charging and output via two USB-C ports lets it charge laptops and feed cameras quickly.
• Compact, flight-friendly 99Wh capacity that still provides substantial runtime for cameras and phones.
• Clear smart display and a wide range of ports improve usability on the rig.
• Solid safety protections and industry certifications give peace of mind when powering expensive gear.

Cons

• Some users report mixed experiences with long-term battery life and occasional faster-than-expected discharge, so runtime can vary by device and usage pattern.
• At 23.3 oz it is lighter than many full-size V packs but still adds noticeable weight compared with single cell USB batteries.
