SMALLRIG V Mount Battery VB99 Pro 99Wh V-Lock - Portable 100W Power

Our review of the SMALLRIG VB99 Pro V-mount battery finds it best suited to creators who need a compact, airline-friendly power solution with flexible output options. The single biggest reason to buy is its combination of a genuine 99Wh capacity with 100W PD fast-charging and multiple ports, which keeps cameras, monitors and even a small laptop running without bulky power bricks. The design is deliberately compact and integrates a V-lock plate and rod-clamp options so it swaps easily between a shoulder rig, monitor mount or a small studio setup.

Key Features

• Integrated V-lock plate: Provides a standard V-mount interface so the battery mounts securely to camera rigs and powers V-mount devices directly.
• Bi-directional PD 100W: Two USB-C ports support PD 3.0 and can deliver up to 100W for fast charging of the battery or powering laptops and monitors on the move.
• Multiple output ports: Includes USB-A, DC 8V, DC 12V, BP and D-TAP ports for feeding cameras, lights, monitors and phones without adapters.
• Palm-size body: At roughly 4.2 by 2.9 by 2.2 in and about 23.3 oz, it balances a high 6800mAh capacity with a design that fits compact rigs and carry-on travel.
• Versatile mounting: The V-mount backplate has 1/4"-20 and 3/8"-16 threaded holes plus countersinks and an ARRI locating hole for flexible attachment of rod clamps and accessories.

Who It's For

This battery is ideal for videographers and hybrid shooters who travel or work on location and need a compact V-mount solution that stays under the 100Wh airline limit. It suits users running mirrorless cameras, small cinema cameras, external monitors and lights who benefit from PD charging to top a laptop or power a monitor while shooting.

It is less appropriate for teams who require extremely long runtimes without swapping batteries or those who need higher-capacity power for long studio shoots; in those cases a larger V-mount battery or multiple batteries would be better. Also, users who cannot use PD chargers should note charging rules for D-TAP and other ports.

Pros & Cons

Pros

• Compact 99Wh design that is carry-on friendly and fits small rigs easily.
• Strong port selection including two USB-C PD ports and D-TAP for broad device compatibility.
• Fast 100W bi-directional charging reduces downtime when paired with a capable GaN charger.
• Sturdy build and thoughtful mounting points for flexible rigging.

Cons

• Battery life perceptions vary; some users report shorter runtimes than expected under heavy loads.
• At about 23.3 oz some shooters find it heavier than hoped for on very minimal rigs.
