SMALLRIG V Mount Battery VB99, 99Wh 100W Output - Fast PD Charging

In this review the SMALLRIG V Mount Battery VB99 is evaluated as a compact power solution for run-and-gun shooters and small rig builders who need dependable, portable energy. The single biggest reason to buy is the combination of a true 99Wh capacity in a palm-size V mount pack with a 100W USB-C PD port that supports fast bi-directional charging, allowing the battery to both power gear and recharge quickly when used with a 100W GaN charger. For anyone traveling with camera gear the TSA-friendly capacity and multiple output options make it especially useful.

Key Features

• 100W bi-directional PD: The USB-C port supplies up to 100W to run a laptop or fast-charge the battery for a quick turnaround between shoots.
• Multiple output ports: USB-C, USB-A, DC 8V, DC 12V, BP and D-TAP allow simultaneous powering of a camera, monitor and accessories without extra adapters.
• Compact footprint: At roughly 4.21 x 2.87 x 2.08 in and 19.4 oz it fits on compact rigs or in a carry-on without taking much space.
• OLED power monitoring: The bright screen shows port status, voltage, power output and remaining battery life so users can plan runtime precisely.
• Fast 2 hour full charge: With a 100W or higher GaN charger the VB99 reaches full charge in about 2 hours, reducing downtime on location.
• Built-in mounting options: V-mount backplate includes 1/4'-20 and 3/8'-16 threaded holes to secure the battery with a ball head or clamp.

Who It's For

The VB99 is aimed at hybrid shooters, vloggers and small production crews who need a lightweight V mount battery that can also top up laptops and phones via USB-C. Its 99Wh capacity makes it ideal for travel where larger V packs are not allowed as carry-on, and the multiple ports are convenient for running a camera, monitor and a small LED light at once.

Those who require extremely long runtimes for full-day shoots or have professional cameras that draw very high current may prefer larger capacity V mount batteries. Also, users needing a dedicated charging ecosystem of brand-specific batteries for extended multi-battery swaps should consider full-size V lock batteries instead.

Pros & Cons

Pros

• Compact and light with a useful 99Wh capacity that is carry-on friendly for travel.
• Versatile outputs including USB-C PD 100W and D-TAP for mixed-device setups.
• Fast recharge time of around 2 hours with an appropriate 100W or higher charger.
• Clear OLED display and simple controls give accurate real-time power information.

Cons

• Some customers report inconsistent charging behavior, so occasional reliability issues have been noted.
• At 6800mAh it can power lighter setups well but will be limited for very power-hungry cameras over long shoots.
