Power outages don’t send you a warning text before they strike and the last thing you want is to be scrambling in the dark wondering how long your fridge will stay cold or how you’ll charge your phone. That’s exactly why portable power stations have become essential backup gear for people who want peace of mind during emergencies, camping trips or off-grid adventures.
EcoFlow initially kicked off Prime Day with their Delta 2 priced at $449 for this 1800W portable power station, but then Jackery dropped their 1500W model to $349. EcoFlow responded by matching that price, even though their unit delivers more power. Right now, exclusively for Prime members during Amazon’s Prime Big Deal Days, you can grab this EcoFlow Delta 2 beast for $349, down from its original $699 price tag. This marks an all-time low for an 1800W portable power station.

Lightning-Charge That Outpaces Other Brands
The 1800W continuous output is where things get really practical: This power station is capable of powering your fridge, microwave, coffee maker, portable air conditioner, power tools and just about any household appliance you’d want to run during an outage. With 15 varying outlets built across the unit, you don’t have to worry about running multiple devices simultaneously by playing musical chairs with your electronics. There are six AC outlets for standard plugs, two 100W USB-C for laptops and tablets to be quickly charged, several USB-A for phones and smaller devices and DC outlets for your 12V devices.
The capacity sits at 1024Wh thanks to a LiFePO4 battery which is chemistry shorthand for lithium iron phosphate. This battery type is tougher and safer than standard lithium-ion batteries you find in cheaper units. More importantly, it can handle over 3000 charge cycles before capacity starts dropping, which translates to roughly six times longer lifespan than older battery technology. You could charge and drain this thing once per week for over 50 years before hitting that 3000-cycle mark.
The game-changer here is the charging speed: The Delta 2 goes from completely dead to 80% charged in just 50 minutes using a standard wall outlet, and hits 100% in 80 minutes. That’s seven times faster than most portable power stations on the market. This rapid charging capability means you can quickly juice up before heading out on a weekend camping trip or get your backup power ready in a hurry when storm warnings hit your area.
What sweetens the pot even more is expandable capacity: The base unit offers 1kWh of storage, but additional battery packs can be added to triple it to 3kWh. The modular configuration means you start small but expand your system as needed, ideal for serious RV owners or individuals outfitting off-grid systems. The ability to charge by solar adds even more independence. The Delta 2 takes a whopping 500W of solar panel (sold separately) input so it stays topped off during longer camping forays or serve as a truly renewable backup at home.
For $349, you’re getting a high-end 1800W portable power unit for less money than many companies are asking for their mid-range 1000W models. Make sure you don’t miss that Prime Day deal.
