Deep discounts on backup batteries and solar gear

Portable power company EcoFlow is offering steep Black Friday discounts on many of its best-known battery systems, with some models marked down by more than half, according to Engadget’s deal roundup. The promotion covers a wide range of products, from compact River-series batteries for camping or balcony gardening to large-capacity Delta Pro units that can keep major appliances running during a blackout. Engadget notes that the flagship Delta Pro 3 is hundreds of dollars cheaper than usual, briefly hitting one of its lowest prices ever, while bundles that add solar panels or extra batteries are also reduced. For buyers in blackout-prone areas, the deals effectively lower the entry cost of building a small home-backup system.

The site points out that these portable stations are more versatile than traditional fuel generators: they can be used indoors, recharge from wall outlets, car chargers or rooftop panels, and double as giant power banks for electronics and tools. Still, Engadget cautions shoppers to look closely at each model’s watt-hour capacity and maximum output so the battery can actually handle what they plan to plug in, whether that’s a fridge, router, or workstation. It also recommends checking port selection—USB-C, AC outlets, and DC ports—plus battery chemistry and cycle life, because cheaper units may degrade faster under heavy use. With Black Friday now stretching over several days, the price cuts underscore how competitive the backup-power market has become, especially as extreme weather and grid stress make resilience tech feel less like a luxury and more like insurance.

What to check before you hit “buy”

While the headline discounts are attention-grabbing, Engadget highlights a few practical steps to avoid buyer’s remorse. First, calculate a rough daily energy need by listing critical devices and how long you want them to run; that helps determine whether an entry-level River, mid-range Delta 2 or a heavier Delta Pro makes sense. Second, consider weight and portability: the largest units can be difficult to move without wheels, which matters if you live in a walk-up apartment or plan to take the power station on the road. Third, think about noise and heat, especially for smaller rooms, since the cooling fans on big packs can get loud under sustained load. Finally, remember to budget for accessories, such as extension cables, transfer switches or compatible solar panels, because those affect the total cost as much as the base unit. With the right planning, though, the current wave of discounts could allow more households and small businesses to add a layer of energy security at a price that was out of reach a few years ago.
