The SWIT PB-M90S is a compact, pocket-sized V-Mount battery engineered for filmmakers who demand serious power in a tiny footprint. Packing 90Wh / 6.25Ah of capacity across eight high-class 18650 cells at a nominal 14.4V, it comfortably powers small cine cameras, handheld stabilizers, follow-focus monitors, and LED lights — all while remaining airline carry-on compliant.
Despite its miniature form factor, the PB-M90S delivers a remarkable 120W / 10A constant load, supports 3A fast charging via any standard V-Mount or D-Tap charger, and features SWIT’s innovative Wire-Free internal PCB technology for reduced internal resistance, a stabler circuit, and long-term reliability on demanding shoots.
Key features
- Pocket-fit V-Mount design: Ultra-compact body sized to slip into a jacket pocket, yet fully compatible with standard V-Mount cameras, monitors, lights, and stabilizers.
- 90Wh fly-friendly capacity: 90Wh / 6.25Ah at 14.4V keeps you powered through long shooting sessions and is approved for airline carry-on luggage without restrictions.
- 120W / 10A constant high load: Handles power-hungry devices without voltage drop, making it suitable for high-performance cine cameras and bright LED panels.
- D-Tap output & charging input: The built-in 120W/10A D-Tap socket doubles as a charging port, compatible with the SWIT PC-U130B2 dual D-Tap charger for versatile on-set power management.
- 5-LED power indicator with low-battery alert: At-a-glance remaining charge display; the final LED flashes automatically when power drops below 10% so you are never caught off guard.
- Wire-Free internal technology: All cells, D-Tap connectors, and indicator components are directly soldered onto the PCB — no internal wiring — minimising resistance and maximising circuit stability and safety.

Frequently asked questions
Can I take the SWIT PB-M90S on a plane as carry-on luggage?
Yes. The PB-M90S has a capacity of 90Wh, which falls within the internationally accepted 100Wh carry-on threshold, making it fly-friendly for most airlines without requiring special approval.
What devices can the SWIT PB-M90S power, and how do I charge it?
The PB-M90S can power small cine cameras, handheld stabilizers, follow-focus monitors, and LED lights via its V-Mount plate or its built-in D-Tap socket (120W/10A). It can be charged by any standard V-Mount charger or a D-Tap charger such as the SWIT PC-U130B2, with a maximum charging current of 3A — reaching full charge in approximately 3 hours with a single-channel charger.
What makes the Wire-Free internal technology important for reliability?
SWIT's Wire-Free technology means all internal components — cells, D-Tap sockets, and the LED power indicator — are directly soldered onto the PCB with no connecting wires. This eliminates a common source of internal resistance and potential failure points, resulting in a more stable, safer, and longer-lasting battery.
