We’ve covered portable power stations like the Anker SOLIX line , but if you’re looking for a heavy-duty, large-capacity model that can handle sump pumps, large AC units, multiple appliances, and even whole-home backup with extra batteries, brands like EcoFlow will better suit your needs. One of their award-winning models is the EcoFlow Delta Pro 3 power station, which is currently available at a 46% discount, bringing it down to an all-time low of $1,999 (originally $3,699).
Compared to Anker’s most powerful model, the SOLIX C2000 with a 2,048Wh capacity, EcoFlow’s Delta Pro 3 nearly doubles that at 4,096Wh and is expandable to up to 48000Wh. It supports 120V/240V voltage and can be recharged in a variety of ways, including solar panels, AC outlets, gas generators, and EV charging stations. It’s powered by a lithium iron phosphate battery, which is longer-lasting, safer, and tolerates more cycles than many competing power stations on the market.
Compared to a gas generator, it operates quietly and doesn’t give off dangerous exhaust fumes, so it’s suitable for indoor use. It can be controlled and monitored via a companion app that tracks generation and power usage history and calculates the estimated time until empty. Although PCMag, which gave it an Editor’s Choice Award , calls it “elegant-looking,” it’s an undeniably heavy device at over 100 lbs due to its massive output, so it’s not as portable as many competitors. This makes it better for vehicles or semi-permanent setups rather than camping trips or hiking.
If you want a serious backup power solution for your home and your priorities are a high power capacity with expandability, versatile recharging options, and a quiet, indoor-friendly alternative to a gas generator, the EcoFlow Delta Pro 3 power station is your best bet, especially at nearly half off. However, if you only need to power small devices or use it for travel, it will most likely be overkill, and a cheaper model from the Anker SOLIX line (or the Ecoflow River 2 ) might be better for your needs.
