As part of Best Buy’s Deals of the Day, the EcoFlow store is offering the 1,024Wh DELTA 3 Classic Portable Power Station with a bundled 45W solar panel down at $499 shipped. This price matches the standalone DELTA 3 Classic rates from the direct website and Amazon, meaning you’re getting the $99 solar panel for FREE. While we haven’t seen this particular bundle before, it would typically run you $598 in full with the recent pricing. Be sure to also check out EcoFlow’s current Labor Day Sale lineup here, which also added a four-day Monthly Madness flash sale.
The EcoFlow DELTA 3 Classic power station is a solid option for folks who only need a smaller 1,024Wh LiFePO4 capacity model to cover devices and small appliance power. It delivers up to 1,800W of steady output through its six ports (3x ACs, 2x USB-Cs, 1x USB-A), and can surge as high as 3,600W when needed. It brings along four main recharging methods: using an AC outlet, a gas generator (with passthrough charging functionality), up to 500W of solar panel input, or with the brand’s 500W alternator charger.
As I mentioned, EcoFlow currently has a Labor Day Sale with up to 58% discounts on power stations starting from $169, as well as an August EcoCredits Monthly Madness flash sale with deals starting from $1. There’s also the other deals from this and other brands that you can check out in our dedicated power stations hub here.
EcoFlow DELTA 3 Classic Portable Power Station features:
- 1800W Output with X-Boost TechnologyPower 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 ChargingCut 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 BuildEngineered 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 CapabilityHarness 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.
