Having a small portable power station is great for camping or keeping your phone charged during a quick outage, but if you’re in a multi-day blackout situation or need to power a larger appliance, those smaller options probably won’t cut it. If you need real backup power but hate the idea of a noisy, smelly gas generator, then these massive battery systems are what you should be looking at.

As of Oct. 20, the EF EcoFlow Delta Pro 3 is on sale for $3,599, down from $6,298, at Amazon. That’s a 43% discount and a $2,699 price cut. On top of that, because the purchase is over $2,000, it qualifies for a free gift from EcoFlow — in this case, a free portable solar panel to get you started with off-grid charging.

The bundle gets you the Delta Pro 3 (which has 4kWh on its own) plus an extra 4kWh battery. That’s 8kWh capacity right out of the box. Need even more? You can keep stacking batteries up to 48kWh. It’s powerful enough to run almost anything, with a 4000W output and both 120V and 240V options, so it can handle big stuff like a central AC unit or even charge an RV.

And while these stats may seem intimidating, it’s designed to be pretty user-friendly. It has a super-fast 10ms UPS switch-over (which means your connected devices won’t even blink if the power goes out). It uses long-lasting LFP batteries and is surprisingly quiet when running, humming along at just 30 dB thanks to EcoFlow’s X-Quiet tech.
