Power outages during winter storms can leave you without heat, light or the ability to charge essential devices for hours or even days. A portable power station with serious capacity means you can keep critical appliances running, charge phones and laptops repeatedly and maintain some comfort until power returns. The EcoFlow Delta 3 delivers 1024Wh of battery capacity with 1800W output which is enough to run space heaters, fridges or medical equipment when the grid goes down. Amazon dropped it to $519 from its usual $699, matching the Prime Day price except this deal applies to everyone, not just Prime members. This all-time low makes serious backup power accessible right before the season when you’re most likely to need it. See at Amazon Why the Delta 3 Outperforms the Delta 2 EcoFlow released the Delta 3 as a direct upgrade to the popular Delta 2 and the improvements address the main complaints users had with the previous generation. The most significant change is charging speed: The Delta 3 reaches full capacity in 56 minutes by combining 1500W AC input with 500W solar input simultaneously, compared to the Delta 2’s 80-minute charge time. When you’re dealing with an extended outage and need to top up quickly during daylight hours or between power fluctuations, that 24-minute difference means getting back to full capacity nearly twice as fast. An 80% charge takes just 30 minutes which covers most emergency situations where you need power immediately. Delta 3 is identical to the Delta 2 LiFePO4 chemistry-wise but with more sophisticated cell management: Both give 4000 cycles to 80% capacity but the battery management system on the Delta 3 extends the practical lifetime to 10 years under day-to-day usage, approximately 25% longer than industry average for this type of battery. The IP65-rated battery pack provides triple protection against splashes, dust, and oil. This rating means you can use the EcoFlow Delta 3 outdoors during light rain or in dusty construction environments without worry. The Delta 2 lacked this weatherproofing, limiting its usefulness for outdoor sites or emergency situations where you might need to set it up outside temporarily. 1800W continuous output powers most home appliances without sacrifice: Space heaters, cofee makers, power tools, refrigerators, and some window air conditioning units fall firmly in this range. X-Boost technology goes further for resistive loads like heaters and hair dryers, and it can power up to 2600W continuously by bypassing some of the normal power conversion limitations. The feature lets you use higher-wattage appliances that otherwise would require a larger, more expensive power station. The Delta 3 powers 13 devices simultaneously through its array of outlets: six AC outlets, two 100W USB-C ports, two USB-A ports, one car outlet, and two DC5521 ports. The dual 100W USB-C ports charge modern laptops at full speed, meaning you can work through an outage without rationing battery life. During a winter storm that knocks out power for 12 hours, the 1024Wh capacity can run a small space heater on low for about 3-4 hours, charge multiple phones 80+ times, or keep a CPAP machine running for two full nights. The price point at $519 is approximately the same price the Delta 2 yielded last year, so this upgrade comes at absolutely no cost while getting the advantage of twice the fast charging, the latest weatherproofing, and the latest ecosystem support.
