POWER YOUR MISSION. SIMPLIFY YOUR GEAR.
Introducing NPO EPS-A1, the ultimate power management solution for the modern shooter and outdoorsman. This isn't just a battery holder; it's an intelligent- Picatinny Battery System that combines a high-speed batterycharger with a direct-output power bank, engineered for the most demanding environments. Mount it and forget it — your power problems are solved.
SMART, INTUITIVE POWER MANAGEMENT
- Charge & Discharge from One Port: Use the single, high-speed USB-C port to recharge the installed battery, or to power your device (like a red dot sight or thermal scope) directly—eliminating the need for constant battery swaps.
- At-a-Glance Status Indicator:
Solid Blue: Discharging---The battery case is supplying power to an external device.
Breathing Green Pulse: Charging---The battery case is receiving power from an external charger.
Solid Green: Fully Charged---The battery is fully charged.
MAXIMUM COMPATIBILITY & CONVENIENCE
NPO ESP-A1 Battery Compartment is designed for universal use and effortless operation.
Fits All 18650Cells: Works perfectly with both flat-top and button-top 18650batteries. No compatibility issues.
BUILT TO OUTLAST YOUR TOUGHEST ADVENTURES
The NPO EPS-A1 is engineered for those who demand uncompromising durability from their gear. Every aspect of its construction is designed to withstand the harshest conditions while maintaining a compact, lightweight profile.
- Rugged Structure with Compact Design
Precision-machined from aerospace-grade 6000 series aluminum in a single CNC cycle, the EPS-A1 delivers exceptional strength with a minimalist footprint. This full-metal construction provides reliable protection while weighing just 80 grams—adding minimal bulk to your setup without sacrificing durability.
- 1000G Impact Rated
Tested to withstand forces exceeding 1000G, your power supply stays secure and operational even under the heaviest recoil and roughest handling.
- 2-Year Manufacturer's W-arranty
Our confidence in the EPS-A1's durability is backed by a comprehensive 2-year manufacturer's wa-rranty—so you can focus on your mission with complete peace of mind.
CERTIFIED PROTECTION YOU CAN TRUST
The NPO EPS-A1 isn't just built tough—it's tested and certified to meet the highest standards of environmental durability.
- IP68 Waterproof Rating: Independently tested to withstand immersion in 1 meter of water for 45 minutes—far beyond standard requirements. Whether you're operating in heavy rain, crossing streams, or facing unexpected submersion, your power supply stays fully protected.
- Complete Dustproof Protection: The IP68 certification also guarantees complete protection against dust and debris. Tested to keep harmful particles out, the EPS-A1 performs flawlessly even in the harshest desert, dirt, or sandy environments.
- UL Tested & Verified: The EPS-A1 has successfully passed rigorous UL testing, confirming its safety and reliability under extreme conditions.
When your mission takes you into the elements—rain, dust, mud, or snow—trust the EPS-A1 to deliver.
ENGINEERED TO TAKE THE HIT
1000G Shock Tested – Proven Under Fire
The EPS-A1 isn't just built to hold a battery — it's built to survive the brutal reality of high-recoil firearms and rough field use.
Real-World Testing, Not Just Lab Numbers
We didn't rely on standard drop tests. We built a dedicated shock testing platform and simulated impacts based on actual recoil waveforms collected from live-fire shooting.
1000G Impact Rated – Tested to withstand forces exceeding 1000G
Recoil Waveform Simulation – Each test replicates real shooting conditions
Post-Test Function Verified – Every unit is checked for full operation after impact
Your Power Stays Secure. Your Gear Stays Online.
MOUNTS IN SECONDS
Tool-Free Quick-Detach Mount: The secure, spring-loaded clamping mechanism provides a vice-like grip on any standard rail. Attach or remove in under 3 seconds with no tools required.
Compact & Lightweight: Adds minimal bulk and weight to your setup, maintaining your device's balance and handling.
Premium Included Cable: Comes with a specialized, high-durability USB-C cable featuring both straight and 90-degree connectors for optimal cable routing in tight spaces.
Perfect For Outdoor & Survival Gear requiring rail-mounted power
- In the Box:
1x EPS-A1 Battery Compartment
1x USBC Power Adapter
1x Dual-ended USB-C Cable (Straight + 90-degree)
1x Backup Screw
