Meet the DELTA 3 Ultra Plus Portable Power Station—a high-performance, ultra-reliable backup power solution built for demanding home and outdoor use. Delivering 3600W of continuous output and an impressive 7200W surge, it can handle heavy-duty appliances with ease, and with X-Boost™ mode it supports loads up to 4600W for added versatility. Designed for long-term dependability, it features automotive-grade full-tab LFP cells engineered for 10 years of reliable power, reinforced by 24/7 battery management protection, Class-B certification, and an EV-grade CTC structure that stands up to transport bumps and moisture.
 
For seamless home integration, the DELTA 3 Ultra Plus supports two easy connection options—a Manual Transfer Switch or Inlet Box—and delivers a 10ms auto-switch to help keep critical systems like servers and NAS devices running without interruption. Despite its power, it stays remarkably quiet with whisper-level operation as low as 25dB (at 600W). With OASIS 3.0 smart app control, you can monitor battery status in real time, track electricity pricing, automate energy-saving schedules, and activate Storm Guard Mode to prepare for severe weather. Backed by up to a 5-year warranty (with app registration), it’s a portable power upgrade you can trust every day.
