SMALLRIG VB99 Pro V-Mount Battery 99Wh / 6700mAh with 100W PD and Multi-Port Power
Product description
What it is and what it’s for
The SMALLRIG VB99 Pro is a V‑Mount battery designed for filmmakers and photographers who need reliable, portable power. With a substantial 99Wh capacity (6700mAh at 14.8V) and a sturdy aluminium shell, it aims to balance compact size with useful runtime for cameras, monitors and ancillary devices on location or in studio setups.
How it charges and powers other gear
On paper, the VB99 Pro supports fast charging and bi‑directional power via USB‑C, capable of up to 100W. This means it can both charge itself quickly and power other devices that support USB‑C PD without the power going soft when multiple devices are drawing current. There are additional output options: USB‑C x2, USB‑A, D‑TAP, and DC ports. In practice, that translates to powering a camera body, an external monitor, and a small light or laptop in parallel, subject to the overall 100W limit.
Build and reliability notes
This battery uses high‑quality power cells and an intelligent BMS to guard against short circuit, temperature rise, over‑voltage, over‑current and other common faults. It carries multiple safety certifications (CE, RoHS, FCC, UKCA, ISED, RCM and more) which adds confidence in typical production environments. The front TFT display provides real‑time readings for each port and the total output, so you can keep track without guessing.
Design and usability: who it suits
The VB99 Pro is designed with field use in mind. At roughly 4.2 × 2.9 × 2.2 inches and about 23.3 oz, it sits in a sweet spot between manageable weight and useful runtime. The backplate includes threaded holes for mounting with supports or clamps, which can help in tight setups where space is at a premium. The case uses aluminium alloy with protective PC/acrylic covers to guard the display and internals. If you often work on location, where you need a compact, reliable power bank with multiple outputs, this model is worth considering.
Limitations and what to watch out for
If you rely heavily on USB‑C PD to drive several high‑draw devices at once, you’ll need to watch the total output. The device states a 100W total limit and advises using PD protocol to maximise charging efficiency. It’s not clear how the 100W is allocated across ports under peak demand, so you may see reduced charging speed on some ports when several devices are pulling power. Also, the exact charging time to full depends on the charger used and the PD negotiation, while 2.5 hours is cited for some conditions, real‑world results can vary.
Before you buy: quick considerations
- If you already need a compact V‑mount battery with multiple outputs, this could streamline power for a camera, monitor and accessory devices in one pack.
- Check how you plan to balance runtime against weight, 99Wh is substantial but still a factor for long shoots away from a mains supply.
- Ensure your charger and devices support PD and that a USB‑C connection is suitable for your main power needs.
- If you frequently run high‑demand loads from several ports at once, consider whether your workflow can distribute load to stay within the 100W limit.
How it compares in practice
Compared with more basic battery packs, the VB99 Pro offers a broader set of outputs (two USB‑C, USB‑A, D‑TAP, and DC ports) and a compact form factor with a clear display. It’s a sensible step up if you want a single power solution for camera, monitor and some accessories, rather than juggling separate power banks. It’s less ideal if you require very high sustained power for multiple devices simultaneously beyond the stated 100W total or if you need longer runtimes without recharging.
Final buying decision
Is it worth it? It makes sense if you prioritise a compact V‑mount battery with flexible outputs and a clear quick‑check display, suitable for on‑set power management without swapping packs. It may not be the best match if your workflow constantly demands more than 100W total across devices or if you need translucently long runtimes between charges.
Practical usage example
Imagine you’re filming a compact interview rig: a camera body, an external monitor, and a small light. With this VB99 Pro, you could run all three from the battery, keeping a tidy setup without multiple power bricks. The built‑in display lets you verify remaining power and port status between takes, helping you plan a swap before the battery runs out.
Quick FAQ
- Will it charge another device while charging the battery? Yes, via USB‑C PD up to 100W total for the battery and connected devices, subject to the 100W limit.
- How robust is the build? The housing is aluminium alloy with protective coverings and has multiple safety certifications, aimed at on‑set reliability.
- What if I need more than 100W at once? The battery’s outputs total up to 100W, so plan your load accordingly or distribute across devices to avoid exceeding the limit.
What’s included
The description notes a 240W USB‑C charging cable is included, designed to support faster, more stable charging alongside the battery itself.
