Twin Power

Dual power means the flashlight can run on two different power sources, typically a built-in rechargeable battery and standard alkaline AA or AAA batteries. What differentiates Twin Power from normal dual power lights is that both batteries sit inside at the same time and you can switch between them anytime. If your rechargeable battery runs low, you can swap to alkaline and keep going instead of losing light entirely while you switch to your backup set.

The Twin Power system by Police Security Flashlights uses a single cartridge that holds both a rechargeable battery and alkaline backup batteries simultaneously. A one-button toggle lets users switch between power sources without removing or swapping any batteries. This design means the light stays operational even when the rechargeable cell is depleted. The technology is patented and earned Police Security's flagship product status across its flashlight and headlamp lineup.

A standard rechargeable flashlight is only as reliable as its last charge; if the battery dies and you don't have a charger handy, the light is unusable. Dual power flashlights solve that by letting you drop in AAA batteries as backup, which matters most during power outages, emergencies, or off-grid trips. Twin Power lights take this further by storing the backups inside at all times so you still have access to instant light, even if your main battery gets low.

Yes. Because they don't rely on a single power source, Twin Power® flashlights are well suited for emergency kits, storm prep, and vehicle glove boxes, where you can't count on a wall outlet being available when you need light most.

Yes, all Twin Power products charge via USB-C, allowing use with standard cables and modern wall adapters, power banks, and car chargers. A built-in battery level indicator shows remaining charge so users know when to recharge before the rechargeable cell is depleted. The combination of USB-C convenience and the built-in alkaline backup means the light remains usable even if a charging source is temporarily unavailable.
