Amazon is now offering the Greenworks 40V 500W 4-Slot Portable Power Station at $455.99 shipped, which beats out its direct pricing by $144. It normally goes for $600 at full price, which is where it’s still priced direct from the brand’s website, with very few discounts over the year – the greatest of them being today’s deal to the best rate of 2025. While it did fall lower in 2024, you’re still getting the best price that we have tracked this year, with a 24% markdown here that cuts $144 off the tag.

Much like EGO’s Nexus power station, this Greenworks power station is a great option if you want to get more use out of the brand’s 40V batteries beyond just powering tools. It comes with four different slots, each of them able to hold one battery, which contributes towards powering any connected devices or appliances. There are seven output ports to cover connection needs: 2x 500W ACs, 2x 30W USB-As, and 3x 65W USB-Cs. Not only is there an onboard LCD screen to keep track of battery capacities and real-time charging levels, but it also sports in-app smart controls so you don’t have to stay close to keep monitoring it.

Speaking of Greenworks, you can find various deals on the brand’s tools – alongside countless other tool brands – by regularly checking in on our dedicated tool hub here.
