SmallRig V Mount Battery VB99 (99Wh / 6800mAh) with PD 100W fast charging, OLED screen and D-TAP
Product description
The essentials
If you run cameras, monitors or lights on a V-mount ecosystem, a 99Wh battery is a sensible “step up” that still keeps travel in mind. The SmallRig V Mount Battery VB99 is built around that idea: 99Wh capacity, multiple power outputs, and a PD 100W USB-C port for powering (or charging) compatible devices. On paper it’s also quite compact for what it is, and the OLED display aims to remove the guesswork when you’re on set.
That said, it’s not a universal answer for every workflow. If your kit expects a different battery standard or you only need very low-power trickle charging, there are usually simpler, lighter options.
It’s most convincing when you want one battery that can handle camera-style loads plus the “small extras” like monitors, video lights, or device charging without constantly swapping supplies.
What matters most day to day
The VB99 is designed to be easy to live with. The OLED screen gives instant visibility of the port status, output voltage, output power, and remaining battery life. It’s a small detail, but in real shoots it helps you avoid the classic scenario: you’re halfway through a take, then suddenly you’re checking battery apps and guessing.
Control is built around simple button presses: - a single click to show live updates - a double click to switch between voltage and power screens - a long press (3 seconds) to stop output on the USB-C, USB-A and DC (CC) ports
One practical example: if you’re powering a field monitor and charging a phone off the same battery, you can glance at the OLED for current output before deciding whether to keep both running or dial back.
The VB99 is also described as 99Wh, which is positioned as meeting TSA air travel requirements for carry-on (under 100Wh). If you travel often with production gear, that’s the kind of detail that can matter more than raw capacity.
Ports and versatility (without pretending it’s one battery for everything)
Where this battery earns its keep is in its range of interfaces. The SmallRig VB99 includes USB-C with up to 100W via PD 3.0, plus USB-A and multiple DC options (8V and 12V), along with D-TAP. There’s also a 1/4"-20 and 3/8"-16 threaded hole on the rear mounting plate, so it can be secured with a compatible ball head or clamp.
The “PD 100W fast charging” part is the headline, and it’s aimed at charging a compatible device when you have a suitable 100W GaN charger (or higher) in your setup. Over the paper: the listing claims a full recharge in about 2 hours with a suitable charger.
Worth noting: charging speed always depends heavily on what you’re charging and which charger you pair it with. If you’re using a lower-wattage charger, don’t expect the same recharge time.
Safety, protection and reliability
This VB99 is set up with a battery management system (BMS) and protection features against the usual risks: short-circuits, over-temperature, over-voltage, over-current, overcharging and over-discharging. On top of that, it’s listed with multiple certifications/standards (FCC / MSDS / UN38.3 / IEC 62133 / UL2054 / UL62368).
None of those details guarantee it will suit every setup, but they do suggest the battery is built to be used seriously, not just as a casual backup.

Who it suits, and who should look elsewhere
It’s a good fit if you want a V-mount battery with real on-device monitoring, plus a USB-C PD 100W port for device charging alongside camera-related power. It makes sense if your kit includes items that can use USB-C PD and you also rely on D-TAP or DC outputs.
It may not suit you if your main priority is ultra-light travel or you only need one fixed output type—then the extra ports and capacity could be more than you need, and the battery might feel overkill.
It might not be a great match if you’re expecting every single cable or device to behave the same way. The VB99 gives multiple options, but the exact results will depend on what you connect and how your devices draw power.
Buying verdict
Should you buy it?
Choose the SmallRig VB99 if you’re building a V-mount powering setup and you want (1) 99Wh capacity, (2) PD 100W USB-C charging, (3) D-TAP and DC options, and (4) an OLED display so you can monitor power without guessing. It’s also a battery concept that fits travel thinking, based on the stated TSA carry-on guidance.
Avoid it if your workflow doesn’t benefit from multiple outputs—especially PD 100W—or if you already have a charging plan that doesn’t involve USB-C power delivery.
Also, before buying, it’s worth checking how your existing kit expects to be powered and whether you actually need both camera-style outputs (like D-TAP/DC) and USB charging at the same time.
Mini FAQ
Does the VB99 support fast USB-C charging?
The listing says the USB-C port supports PD 3.0 up to 100W, so it’s designed for fast charging where your device supports it.
How do I see the battery status?
It has a bright OLED screen with one-click live updates, plus controls to switch between voltage and power. A long press can stop discharge on the USB-C, USB-A and CC ports.
Can it be used for travel?
The listing notes it is 99Wh and states this meets TSA requirements (<100Wh) for carry-on. If you’re travelling, it’s still wise to double-check your airline’s current rules.
What chargers does it mention for recharging?
It states that with a GaN 100W (or higher) charger, you can reach a full charge in about 2 hours. Using lower-wattage chargers may slow that down.
