4-Pack Convenience – Perfect for powering multiple devices, keeping spares always ready, or equipping the whole family's flashlight and headlamp collection with maximum-capacity cells.
Parameters
Applications
Recommended For
-
LED Flashlights & Tactical Torches: Perfect for 21700-powered flashlights from Fenix, Streamlight, and most other brands requiring a button top. The 6000mAh capacity provides the longest possible runtime in a USB-C rechargeable 21700—ideal for extended trips, professional inspection, and emergency preparedness.
-
Headlamps for Outdoor & Professional Use: Ideal for camping, running, caving, and industrial work. The protection circuit prevents over-discharge damage, and USB-C enables easy field recharging from a power bank or car charger.
-
Smart Doorbells & Wireless Security Cameras: Many video doorbells use 21700 cells. The P2160B provides maximum runtime between charges, and the USB-C port allows easy periodic recharging without removing the battery from the mounting bracket.
-
Camping Lanterns & Emergency Lights: Any USB-C power source becomes your charger. The 6000mAh capacity ensures lights stay on through the longest power outages.
-
Portable Fans & Travel Gadgets: Minimize accessories—no separate charger to carry in your travel kit. One USB-C cable charges your phone, tablet, and spare batteries.
Not Recommended For
-
High-Power Vaping / Mechanical Mods: These require 15–35A unprotected cells. The 10A protection limit is insufficient for sub-ohm applications and will cut off power under heavy load.
-
Cordless Power Tools: Drills, saws, and impact drivers demand 20–40A continuous current, far beyond this battery's 10A protection limit.
-
RC Cars, Drones & High-Drain Models: These require 20–30A+ continuous current. This battery will not function and may trigger protection.
-
Ultra-Compact Flashlights with Tight Battery Tubes: This battery measures approximately 76mm in length due to the USB-C port and protection circuit. Some ultra-compact flashlights may not close fully. Always verify your device can accommodate the extra length.
FAQ
Q: How do I charge this battery?
A: Simply connect a standard USB-C cable to the charging port on the battery and plug the other end into any USB power source—a phone charger, power bank, laptop, or car adapter. The built-in LED glows red during charging and turns green when fully charged. A full charge takes approximately 6–7 hours depending on the power source.
Q: Will this fit my 21700 flashlight?
A: It fits most 21700 flashlights that accept button top cells. Due to the integrated USB-C charging port and protection circuit, this battery is approximately 76mm long—about 6mm longer than a standard unprotected 21700 (70mm). Most 21700 flashlights with spring-loaded contacts can accommodate this, but some ultra-compact models may not close completely. Please measure your device's battery tube before ordering.
Q: Can I also charge this battery in a regular 21700 charger?
A: Yes. The P2160B can be charged either through its built-in USB-C port or in any standard 21700 Li-ion charger that accepts button top cells. Both methods are safe and fully supported.
Q: Is this battery suitable for vaping or power tools?
A: No. Vaping devices and power tools require high continuous currents (typically 15–40A). The P2160B's protection circuit limits output to approximately 10A. Using it in such devices will cause the protection to cut off or may damage the battery. For these applications, use dedicated high-drain unprotected cells such as the Vapcell T42 (35A) or K40 (30A).
Q: How much more runtime does 6000mAh give compared to 5000mAh?
A: The P2160B provides approximately 20% more runtime than a 5000mAh cell. In practical terms, a flashlight that runs for 5 hours on high with a 5000mAh cell could run for nearly 6 hours with the P2160B. Combined with USB-C convenience, it is the ultimate upgrade for runtime-critical devices.
Q: How should I store these cells long-term?
A: Store at approximately 3.6–3.7V (40–50% charge) in a cool, dry place using a non-conductive battery case. Avoid storing fully charged or fully discharged for extended periods. The USB-C port makes it easy to top up before use after storage.
