NEEWER PS099S V mount battery 99Wh

If you power small filmmaking rigs on the go, the NEEWER Mini V Mount Battery Smart APP Control is built for practical mobile energy. This 99Wh V mount style battery is compact enough to travel with, while still supporting devices like camera monitor, video lights, and cinema camera set ups. With USB C fast charging plus smart app monitoring, you can keep an eye on input and output power levels rather than guessing what is left. 📷

It also leans into a modern charging approach with up to 100W bidirectional USB C PD fast charging, and it can distribute power to multiple ports at once. There is an OLED screen for on the spot status checks, and a built in safety system that helps protect against common charging and output risks according to the manufacturer. That combination makes it a useful backup power supply when you are on location, filming events, or setting up content workflows where downtime is costly.

The essentials

The PS099S is a mini V mount battery with 6800mAh, rated at 99Wh and 14.5V, so it is designed for powering camera and accessory workflows. It is physically described as compact at 115x77x60mm, and weighing 675g, which can help you keep your carry kit tidy when you are moving between locations. The manufacturer also states it is airline friendly, which matters if you travel with filmmaking gear.

A big benefit here is the smart app control. When you connect the battery to the NE EWER app, you can monitor input and output power levels and see remaining battery life in real time. The app also lets you adjust the output of each port, which can help you optimise power distribution across connected devices. Alongside that, the 1.96 inch OLED screen shows battery status at a glance, including alerts for abnormal conditions.

For charging, the PS099S supports fast charging protocols through the USB C input/output port and the manufacturer states it can deliver up to 100W bidirectional PD fast charging. That means you can charge the battery using a compatible 100W PD GaN charger, and also use the battery to quickly power devices that accept USB C charging. ⚡

What stands out

One reason the PS099S is appealing for creators is how it blends smart control with multi port power. The battery includes several connection options such as dual USB C, a USB A, 5.5x2.1mm DC 8V, 5.5x2.5mm DC 12V, a BP interface, and a D Tap interface, so you can support a mix of camera accessories in the same kit. The manufacturer states you can charge multiple devices at once without a reduction in output power, with a total output not exceeding 100W. 🤳

For cinematography workloads, it is noted as compatible with BMPCC 4K and 6K cinema cameras, plus field monitor and LED video lights. The description also mentions compatibility with a range of V mount battery plates such as ST43, PS005, and PS006, which can help if your setup uses different plate systems. If you are building a compact rig, those connections reduce the number of separate power bricks you need to carry.

There is also a clear safety focus. The manufacturer states the battery includes an intelligent battery management system that helps protect against short circuits, overvoltage, overcurrent, overcharging, and over discharge. It also provides timely alerts in case of abnormalities, and the shell is described as V0 rated fire resistant PC. In addition, the instructions include a practical workaround for a charging interruption scenario, where you turn off the camera, unplug cables, reinsert the battery, then resume charging.

Who it’s for

It’s a good fit if you want a compact airline friendly V mount backup battery for camera rigs and accessories, especially when you are balancing power across multiple devices. It suits creators who like monitoring their power status, since the OLED screen and the app control support real time checks of remaining battery life and power input or output. You will also like it if you run a mix of USB C devices plus DC barrel or D Tap style accessories in the same shooting setup.

It might not be a great match if your workflow requires very specific proprietary power needs not covered by the listed port types and compatibility notes, or if you prefer a simpler battery without app control. Tenants of a minimal kit may still find the multiple ports useful, but the value is strongest when you actually connect several devices at once and want visibility over how power is being used. The PS099S can sit neatly alongside your camera and monitoring gear, keeping your setup ready for fast changes on set. ✅
