Swit OMNI-99S 99Wh USB-C Info Pocket V-mount Battery

The SWIT OMNI-99S is a next-generation pocket-sized V-mount battery engineered for filmmakers, cinematographers, and content creators who demand professional-grade power without the bulk. At just 74 × 102 × 52 mm and weighing 550 g, this battery slips into a jacket pocket yet delivers the sustained output of a full-size V-mount brick — making it one of the most capable compact power solutions available on the market today.

At the heart of the OMNI-99S are eight Sanyo Class-A 18650 Li-ion cells, each rated at 3,450 mAh. These are the highest-grade flagship cells Sanyo produces, chosen specifically for their unrivalled energy density, cycle stability, and long-term reliability. The result is a 99 Wh / 6.9 Ah capacity that is airline carry-on approved, so your power solution travels with you anywhere in the world without checked-baggage restrictions.

Where most compact batteries throttle output as charge depletes, the OMNI-99S is built differently. It maintains a minimum constant output of 150 W at 12 A all the way to near-empty, and at full charge it can handle peak loads of up to 200 W — enough to run high-power LED lights, cameras, and accessories simultaneously without compromising performance. Whether you are powering a mirrorless camera, a monitor, a wireless transmitter, and a small LED panel at the same time, the OMNI-99S handles the combined load with confidence.

Connectivity is as versatile as the battery's output. A bidirectional USB-C port supports 65 W output across the full PD2.0/3.0 voltage range (5 V / 9 V / 12 V / 15 V / 20 V at up to 3.25 A), making it fully capable of powering or even charging modern laptops on location. The same port accepts USB-C PD charging at 48 W or higher, refilling the battery from flat to full in approximately 2 hours 45 minutes — a meaningful advantage when turnaround time between shoots is tight. A standard D-tap port provides 14.4 V output for monitors, follow-focus systems, and other broadcast accessories, and it too doubles as a charging input. An 8.4 V regulated DC barrel output delivers clean, stable voltage for on-camera monitors and compatible accessories, while a USB-A port (5 V / 2 A) keeps phones and tablets topped up throughout the day.

The OMNI-99S features an LED information display that shows remaining battery percentage and estimated runtime at a glance, removing the guesswork from power management on a busy set. The display is recessed into the body with a sunken design that protects it from drops and impacts. Interaction is handled by SWIT's unique "Touchless" sensitive button — a capacitive control that responds without physical pressure, eliminating the risk of accidentally disrupting a recording when handling the battery. A long-press of this button reveals the battery's overall health level, providing actionable insight into long-term cell condition.

Designed for the full spectrum of shooting environments, the OMNI-99S operates reliably across a temperature range of −20 °C to +50 °C. SWIT's proprietary low-temperature cold-start technology ensures the cells initialise and discharge normally in extreme cold — a critical feature for documentary crews filming in arctic conditions, high-altitude environments, or during harsh winter productions.

Standby power consumption is another area where the OMNI-99S stands apart from conventional batteries. Ordinary V-mount batteries typically draw 10 mA or more in standby, requiring periodic top-up charges during storage to prevent cell degradation. The OMNI-99S idles at less than 0.5 mA, dropping further to just 0.01 mA after ten days — so low that the battery can remain in storage for years without losing meaningful charge or suffering long-term cell damage. There is no need for scheduled maintenance charging; simply store it and it will be ready when you need it.

Built-in Battery Management System (BMS) circuitry provides multi-layer protection against overcharge, over-discharge, overcurrent, and short circuit, ensuring both the battery and the devices it powers are safeguarded at all times. Every OMNI-99S unit is manufactured on SWIT's fully automated production line, where rigorous quality standards are enforced at every stage — from cell selection through final inspection — delivering a level of consistency that manual assembly cannot match.

The OMNI-99S also supports digital communication with Sony and RED cameras, delivering precise remaining runtime information directly to compatible camera systems — a workflow advantage borrowed from professional cinema battery standards like the ARRI B-mount system. For camera cage users, pairing the OMNI-99S with optional dummy battery adapters (LP-E6P for Canon or NP-FZ100 for Sony) transforms it into a seamless in-cage power station without loose cables cluttering the rig.

The OMNI-99S is the answer for any production team seeking a battery that is small enough to carry everywhere, powerful enough to run a full cine rig, smart enough to communicate with the camera, and durable enough to work in environments from the Arctic tundra to the desert floor.
