SMALLRIG V Mount Battery X99 - Compact 99Wh HighOutput Power

In this review of the SMALLRIG V Mount Battery X99 the bottom line is simple: it is a compact, travelsafe Vmount that delivers surprisingly high output and flexible ports for run-and-gun video workflows. The battery's 99Wh capacity, 100W USB-C PD bi-directional charging and a clear 2.0in touchscreen make it a practical choice for camera operators and content creators who need reliable runtime, multiple device outputs, and remote management via an app. Durability and safety features target outdoor use while remaining small enough to travel as carry-on.

Key Features

• 99Wh Capacity: Provides long runtime for cameras and monitors without exceeding TSA carry-on limits.
• 100W Bi-directional PD: USB-C port supports PD 3.0 for fast charging the battery and high-speed output to laptops and devices.
• Eight Output Ports: Two D-Tap, two USB-C, BP, two DC barrel outputs and one USB-A let you power cameras, lights, monitors and mobile devices simultaneously.
• 2.0in Touchscreen: An HD color touchscreen with anti-glare surface shows per-port status and allows safe on/off control to avoid accidental shutdowns.
• Intelligent App Control: The companion app monitors multiple batteries, toggles ports remotely, triggers locating lights and manages OTA updates to streamline production workflows.
• Rugged, Travel-ready Design: Reinforced casing, silicone corner protection and IP54 splash resistance make it suitable for outdoor shoots.

Who It's For

The X99 suits camera operators, independent filmmakers and content creators who need a balance of portability and multi-device powering. Its 99Wh rating is ideal for air travel, and the high 100W PD output makes it useful for charging laptops or running power-hungry monitors during location work.

It is less appropriate for productions that demand extremely long continuous runtime beyond what a single 99Wh cell can provide or for those who need proprietary battery mounts specific to a single brand. Users requiring many hours of cinema camera power should consider larger V-mount options or multiple X99 units.

Pros & Cons

Pros

• Compact size and sub-100Wh capacity keeps it airline friendly while still offering meaningful runtime.
• Versatile port selection powers cameras, lights, monitors and mobile devices at once.
• 100W bi-directional USB-C PD and fast 2 hour full charge with a suitable GaN charger saves downtime.
• App control and touchscreen give clear, convenient management of ports and battery status.

Cons

• Some customers have mixed impressions of build quality despite many praising its durability, so expect rugged handling to reveal differences between units.
• At 99Wh capacity it cannot replace larger V-mount bricks for extended multi-day shoots without spares.
