Q: How effective is the solar charging in real-world conditions?

A: Under direct, unobstructed sunlight at equatorial latitudes, the monocrystalline panel delivers approximately 200 mA — translating to roughly 100 hours for a full solar-only charge. In practice, the solar function is best treated as a range-extender: a full day of sunlight adds 5–7 hours of low-mode runtime. For daily-use scenarios, we recommend charging via the Micro-USB port for full capacity.

Q: Can the lantern charge devices while it is itself being charged?

A: Yes. The Sentinel supports pass-through charging — it can simultaneously charge from its Micro-USB input while delivering power to connected devices via the USB-A outputs. The charge controller intelligently allocates input current between battery replenishment and device output.

Q: Is the magnetic base strong enough for vehicle or metal surface mounting?

A: The integrated neodymium magnets provide a secure hold on ferrous metal surfaces up to a 45° angle. For vehicle mounting at highway speeds, we recommend supplementing with the included carabiner as a secondary retention point.

Q: What happens to battery capacity after long-term storage?

A: The Sentinel's battery management system includes a low-self-discharge circuit. After six months of storage at 25°C, the pack retains approximately 85% of its capacity. For optimal longevity, store at 40–60% charge and recharge every three months.

Q: Is the emergency SOS flasher mode compliant with maritime or aviation signaling standards?

A: The SOS strobe (2 Hz, Morse-code S-O-S pattern) is designed as a general-purpose distress signal visible from up to 1 km in clear conditions. It is not certified for maritime (COLREGS) or aviation (ICAO) compliance. For regulated applications, use a dedicated certified distress beacon alongside the Sentinel.
