Managing multiple action camera batteries means carrying loose batteries that can short-circuit, forgetting which batteries are charged, and lacking emergency power for smartphones during extended shoots. The Osmo Multifunctional Battery Case 3 solves all three problems by storing three batteries and two microSD cards whilst intelligently fast-charging all three batteries simultaneously, then functioning as a power bank to charge smartphones or other devices when batteries aren’t needed for the camera.
Perfect For Action Shooters Who Need:
- Organized battery and memory card storage during travel and field work
- Overnight charging of multiple batteries from single USB power source
- Emergency smartphone charging during extended outdoor adventures
- Clear battery charge status without testing each battery individually
- Safe battery transport preventing terminal shorts in camera bags
- All-day shooting capability with multiple charged batteries ready
- Consolidated charging solution reducing cable and charger clutter
Intelligent Three-Battery Charging:
The case charges all three batteries simultaneously using intelligent charging algorithms that monitor individual battery status and adjust charging current accordingly. This simultaneous charging eliminates the sequential charging delays of single-battery chargers, ensuring all three batteries reach full charge overnight from a single USB power source. LED indicators display charge status for each battery independently, enabling quick visual verification of readiness without removing batteries or testing them in the camera. For professional shooters managing multiple cameras or conducting all-day shoots, charge three batteries in the case whilst three additional batteries power cameras in the field, creating a rotation system that maintains continuous shooting capability.
Power Bank Functionality:
When batteries are fully charged and the camera isn’t in use, the case functions as a power bank delivering charge to smartphones, GPS devices, or other USB-powered equipment. This dual functionality means your spare camera batteries serve double duty as emergency power during extended outdoor adventures where mains power is unavailable for days. The total capacity of three Osmo Action Extreme Battery Plus units (3 × 1950mAh = 5850mAh) provides sufficient power to fully charge most smartphones 1-2 times, valuable backup during multi-day hiking, camping, or expedition shooting where phone navigation and communication capabilities are critical safety features. Simply connect your device via USB cable to draw power from the batteries stored inside the case.
Organized Storage Solution:
Beyond charging functionality, the case provides organized protected storage for three batteries and two microSD cards – everything needed for extended action camera shooting in one compact 115.9×59×23mm package. The protective case prevents battery terminal shorts that occur when loose batteries contact keys, coins, or other conductive materials in pockets or bags – a genuine fire hazard that the case eliminates through physical separation. The dedicated microSD card slots keep memory cards organized and protected, preventing the frustrating situation of arriving at shooting locations only to discover you’ve forgotten cards at home or left them scattered across multiple bags. At 84 grams, the case adds negligible weight considering it replaces multiple individual battery storage solutions and eliminates separate chargers.
Cross-Generation Compatibility:
The Multifunctional Battery Case 3 supports batteries from multiple Osmo Action generations including Osmo Action 6, Osmo Action 5 Pro, Osmo Action 4, Osmo Action 3, and Osmo 360. This cross-compatibility means the case remains useful even when upgrading cameras, and enables battery sharing amongst multiple camera bodies if you operate several action cameras simultaneously. For production companies or professional shooters maintaining fleets of action cameras across different generations, a single charging solution compatible with all models simplifies logistics and reduces equipment complexity. The universal compatibility also future-proofs your investment, as the case will likely support subsequent action camera releases that maintain battery compatibility.
Practical Field Use:
During travel, charge all three batteries overnight in your hotel room, then carry the case with fully-charged batteries for all-day shooting without access to power. The compact dimensions fit comfortably in camera bags, jacket pockets, or backpack accessory compartments without consuming space needed for cameras and lenses. For vloggers and content creators conducting multi-location shooting days, keep charged batteries and spare memory cards organized in one case rather than scattered across multiple pockets and bags. Wedding videographers can charge batteries between ceremonies and receptions, maintaining readiness for unexpected extended coverage requirements. Expedition photographers appreciate the power bank functionality during multi-day backcountry adventures where camera battery capacity exceeds actual usage, enabling them to share surplus power with navigation devices or emergency communication equipment.
