1800W Output with X-Boost Technology
Power most household appliances and personal devices with 1800W continuous AC output and 3600W surge capacity. Activate X-Boost mode to expand output up to 2600W, so you can run heavier loads like refrigerators, microwaves, power tools and more without tripping protection. A 100W USB-C port also delivers high-speed charging for laptops, tablets and smartphones without extra adapters.
Ultra-Fast X-Stream Charging
Cut down on wait time with industry-leading charging speed. With X-Stream AC fast charging, the DELTA 3 Classic charges from 0–80% in just 45 minutes and reaches a full charge in approximately 1 hour — so you can get back to using your power faster, whether you’re at home, on the road, or between adventures.
<10ms Uninterruptible Power Supply (UPS)
Protect your sensitive electronics from sudden power outages. With a switchover time of less than 10 milliseconds, this power station automatically transitions to battery backup power for PCs, home servers, medical devices and other critical equipment, preventing data loss, work downtime, and unexpected interruptions.
Long-Lasting LiFePO4 Battery with EV-Grade Build
Engineered for years of reliable use, the DELTA 3 Classic uses premium LiFePO4 battery cells rated for 10+ years of daily use — far longer than traditional lithium-ion or lead-acid power stations. Its EV-grade Cell-to-Chassis (CTC) design and integrated smart Battery Management System (BMS) deliver enhanced safety, optimal performance, and long-term battery health in all conditions.
Fast Solar Recharging Capability
Harness clean, renewable energy to stay fully powered off-grid. When paired with an optional 500W solar panel, the DELTA 3 Classic fully recharges in as little as 2.5 hours. It’s the perfect sustainable solution for remote camping, van life, and long-term off-grid living wherever the sun shines.
