Applications
Recommended For
-
LED Flashlights & Headlamps: Perfect for regulated single-cell lights on medium to high modes. The 3600mAh capacity provides hours of steady illumination—ideal for camping, hiking, and everyday carry.
-
High-Capacity USB Power Banks: Build a compact 7200mAh power bank with two cells in parallel. The 8A rating comfortably supports 18W USB-C PD fast charging. Great for daily carry and travel.
-
Portable Fans & Cooling Devices: Neck fans, handheld fans, and desk fans benefit from the extended runtime. Keep cool through hot workdays, outdoor events, or power outages.
-
Solar Garden Lights & Street Lights: Low-current, all-night operation. The 3600mAh capacity ensures consistent brightness from dusk until dawn.
-
Wireless Security Cameras & Smart Doorbells: Ultra-low standby power consumption with months of operation between charges. Reliable power for motion-activated recording.
-
Medical Devices & Portable Monitors: Stable, dependable power for equipment requiring uninterrupted operation within 8A limits.
Not Recommended For
-
Cordless Power Tools: Drills, saws, and impact drivers demand 15–40A continuous current. The N36 is a capacity cell, not a high-drain cell. Use dedicated high-drain cells like the Vapcell T28 (25A) instead.
-
High-Power Vaping / Mechanical Mods (>8A): Sub-ohm builds and high-wattage regulated mods typically require 15–35A continuous. Using the N36 will cause severe voltage sag and overheating.
-
RC Cars, Drones & High-Drain Models: These require 20–30A+ continuous current. The N36 is engineered for capacity, not extreme current delivery.
-
FET-Driven Flashlights Exceeding 8A on Turbo: If your light's turbo mode pulls over 8A, select a higher-drain cell to avoid performance loss.
FAQ
Q: Why is the CDR 8A? I thought this was a 10A cell.
A: The Vapcell N36 is rated for 8A Continuous Discharge (CDR). Some listings may show higher figures as pulse or marketing ratings, but the safe continuous operating limit is 8A. Always design your system based on the CDR, not pulse ratings, to ensure safe and reliable long-term operation.
Q: Can I use this battery for power tools?
A: No. Power tools like drills and impact drivers require 15–40A continuous current. The N36's 8A CDR is far below what these devices need. Using it will cause severe voltage sag, rapid overheating, and potential battery damage. For power tools, use dedicated high-drain cells such as the Vapcell T28 (25A CDR).
Q: How does the 3600mAh compare to 3500mAh cells?
A: The N36 provides approximately 3% more capacity than standard 3500mAh cells. While the difference is modest, every extra bit of runtime counts in devices that run for hours. It is a slight step up from 3500mAh cells without the premium price of 4000mAh flagship models.
Q: What devices are best suited for this cell?
A: Any device drawing under 8A where extended runtime is valued: LED flashlights on medium/high, USB power banks, portable fans, solar lights, wireless security cameras, smart doorbells, and long-running IoT sensor nodes. It is an excellent everyday high-capacity cell.
Q: Can I build a power bank with these?
A: Absolutely. Two N36 cells in parallel provide approximately 7200mAh—enough to fully charge most smartphones about 1.5 times. The 8A per cell rating easily supports 18W USB-C PD fast charging. Combined with a quality power bank enclosure, it is a great compact high-capacity DIY power bank solution.
Q: How should I store these cells when not in use?
A: Store at 3.6–3.7V (approximately 40–50% charge) in a cool, dry place. Use non-conductive battery cases to prevent accidental short circuits. Avoid storing fully charged or deeply discharged for extended periods.
