AFERIY P310 3600W 3840Wh Expandable Portable Power Station
AFERIY Nomad1800 Portable Power Station 1800W 1024Wh
Industry-First 2kWh Solar Battery with Max 3000W Output (DELTA 3 Max Plus)
A New Era of Power Performance
Next-level energy for next-level peace of mind.
DELTA 3 Max Plus delivers 3000W AC rated output (6000W surge). With X-Boost™ 3.0 technology, it supports devices up to 3900W—effortlessly taking on your heavy-duty appliances. The inverter samples AC voltage and current every 33μs with high precision using a DSP chip, ensuring pure sine wave output with beyond grid-level stability—ideal for powering sensitive electronics reliably.
All Your Essentials. All at Once.
DELTA 3 Max Plus delivers a powerful 3000W output—enough to run your microwave, kettle, fridge, and blender all at once without a flicker. Lunchtime? Go full throttle. No unplugging, no interruptions—just seamless power. [4]
Smart Remote Switching | Reduce waste to increase runtime for essentials
DELTA 3 Max Plus introduces Smart Output Priority Tech. This convenient new feature lets you choose which circuits stay powered via the app. Prioritize what matters—like your fridge, Wi-Fi—and extend runtime when it counts most, even when you’re away.
Smart Power Reserve | Set your desired battery threshold (%) to automatically shed non-essential loads during outages
With app-based presets, DELTA 3 Max Plus automatically follows your priority settings during outages—shutting off lights while keeping your fridge running. Wake up to fresh food and plenty of power left—just like nothing happened.
Long-Lasting, Durable, Always Ready for Emergencies
Rugged exterior and intelligent BMS for unmatched reliability
DELTA 3 Max Plus is equipped with automotive-grade full-tab LFP cells. The full-tab design reduces resistance, enhances efficiency and safety, and provides higher capacity with less heat, resulting in a longer battery lifespan.
With 27% fewer cells per kWh, [7] our 16-cell design runs cooler, lasts longer, and delivers greater stability. Each cell is rigorously tested for capacity, voltage, and internal resistance—resulting in a highly uniform pack that protects against overcharging, imbalance, and premature wear.
From battery chemistry to structural design, DELTA 3 Max Plus is engineered for extreme durability, environmental resilience, and whisper-quiet performance—delivering power you can count on for over 10 years. [2]
