EcoFlow DELTA 2 Max Solar Generator Ditch Gas, Go Solar Winner of Red Dot Design Award 2023. EcoFlow DELTA 2 Max Solar Generator Two in One Bifacial Design: Capture More Energy With a 220W primary side, and a 155W side on the back for ambient light, you can capture up to 25% more solar energy and charge your portable power station even faster. A conversion rate of up to 23% guarantees fast solar charging speeds: 0-100% in 2.6 hours (4 sets), 3.5 hours (3 sets) and 5.4 hours (2 sets). The thin, one-piece tempered glass design of the 220W Bifacial Portable Solar Panel makes it five times tougher than comparable panels with half the thickness of traditional tempered glass. Capable of withstanding heat up to 300°F, it's safe to say it can resist the elements. 10-Year Long-lasting LFP Battery Durable, Safe, Lightweight With its upgraded LFP battery chemistry, DELTA 2 Max has a lifespan of 3000 complete cycles until it reduces to 80% capacity. You'll get pretty much 10 years of power, even if you use it every day. That's 6× longer than other power stations with a similar capacity and output. LFP Battery Chemistry That's 6× longer than other power stations with a similar capacity and output. Advanced BMS Protection A built-in battery management system regulates vitals, including voltage, current, and temperature, keeping DELTA 2 Max safe, secure, and built to stand the test of time. Protective Layers Inside and Out With LFP cells, DELTA 2 Max is safe, durable, and highly efficient. A rubber anti-slip base and a highly-rated UL94-5VA fire-resistant casing offer multiple layers of protection. Robust Design Made with a sturdy one-piece design, DELTA 2 Max is designed for the rough and tumble of portability. Each port is reinforced, protecting them against wear and tear. Upgraded Tech, Lighter Weight Even with its upgraded LFP battery, DELTA 2 Max is still 30% lighter than similar power stations on the market. Run 99% of Appliances with X-Boost Power pretty much anything with up to 3400W Output DELTA Max powers almost all the devices you need with a large 2400W AC output. With X-Boost proprietary technology, run appliances with an output of up to 3400W. Compared with similar portable power stations, DELTA 2 Max can power more devices while also preventing overloading and overheating. 120V Home Backup: Power through outages Power your essential appliances with a hefty 2400W AC output by connecting DELTA 2 Max (2kWh) and up to two Smart Extra Batteries (6kWh) with your home's transfer switch for partial home backup. With a plug-and-play design, it's easier than ever to prepare for blackouts. Power for the entire family 2048Wh Capacity A generous 2048Wh capacity makes DELTA 2 Max ideal for home backup, running your essentials for hours. Using your transfer switch, or plugged in directly, keep your fridge on and stop food from spoiling for up to 14 hours. With its lightweight design, DELTA 2 Max is portable enough to grab and go on the next camping trip.
