EcoFlow early Black Friday deals: Get up to 42 percent off portable power stations

EcoFlow is hosting an early Black Friday sale on portable power stations. This drops prices by up to 42 percent on many of its well-regarded products. For instance, the Delta Pro 3 is on sale for $2,299. This is a discount of 37 percent, as the typical cost is $3,699. That's a significant drop in price. Amazon's matching the sale price as well.

The Delta Pro 3 topped Yahoo's list of the best portable power stations, and for very good reason. This thing is a beast. It boasts a 4,096Wh capacity, so it can power an average 500-watt refrigerator for over 24 hours. That's with continuous use. It can be stretched out to two or three days by only running the appliance during daylight hours. There's even a discounted bundle that includes an extra battery for $3,599.

It includes four standard 120V AC outlets and a single 240V outlet. It could potentially be a temporary hub of a whole-home battery backup. There are numerous charging options here, including a standard AC outlet, solar panels and, interestingly, a cigarette lighter.

The only potential downside here is the Delta Pro 3 really pushes the boundaries of what can be considered portable. It weighs 113 pounds, though it does have wheels and a telescoping handle.

The Delta Pro 3 is just one of the products on sale right now. The Delta Pro Ultra, which is intended as a whole-home backup, is down to $3,999. This represents a savings of more than $2,000. Another Yahoo top pick, the Delta 2 Max, is $1,000 off and down to $899.
