Greenworks 40V 500W Portable Power Station 4-Slot Inverter 2 AC Outlets 5 USB Ports Smart APP Control Power

This works exactly like it should. It's pretty compact and easy to use - just slide the black part onto the battery, and BOOM, you've got power. I haven't tried it under any extreme loads or anything, but it's pretty quiet (quieter than others I've used hooked up to cars), and it seems relatively efficient. It's hard to guess what kind of power you should expect from this (obviously dependent on the battery), but I don't feel like it underperformed at all. I have a couple of Greenworks batteries and no Greenworks tools right now, so I actually got this for emergencies/power outages. I had owned it about 72 hours when our power went out for an extended period of time, and it worked great to power a fan, charge some phones, etc., so it's filling exactly the need I got it for. I haven't come across any concerns yet at all (heat, efficiency, etc.), so all in all, I'm really happy with this little guy. Read more

Can run a fan or recharge phone in my deer blind. Awesome and very useful. Read more

I used this to make my own version of a 40v Ryobi 300w inverter. Ryobi sells their own, but I bought and return ed 3 in a span of 2 weeks. All failing in odd ways, one of them ended up almost catching fire, hah! Whoops! Greenworks inverter here, uses just 2 wires on the connector. Positive and negative. No smarts on connecting to the battery. So apply 40v, and it just works. I cut the greenworks connector off, spliced in a Ryobi connector, and blamo! Ryobi inverter! What actually makes this safe, is that Ryobis batteries have the protection built into them. So if ya pull too much watts, the battery itself shuts off. Voltage gets too low? Battery shuts itself off. They are actually pretty nice. Also, this inverter is marked as 300w, but I've been able to pull 350! The fan runs on super slow if there is no load and ramps up when the load goes up. It's not loud really. The inverter is all metal construction. Unlike Ryobis all plastic version. The USB's actually work! 2 of them. All three of the Ryobi ones died, hah! They would charge when I first got it, then just... Stop working! This inverter is better in every way. If ya know how to do it, they sell the Ryobi 3D printer battery connector for 40v batteries. Make your own. Or just buy into greenworks batteries. I hear those aren't too bad either! Read more

Having invested in the Greenworks ecosystem, this inverter is perfect for mobile electronics. Works well for small electric fans and accessories, even charged small laptops. Never even noticed the fan noise, but it has only been used outside with lots of folks around. A 5-star review would have been a pure sine wave inverter, and I would have paid extra for it. Otherwise, a great accessory to have around. Update: July 20, 2022 Attempted to use it to power a blender (1000 watt). The blades did a partial rotation and stopped. The inverter became very hot - no smoke or smoky smell. Just stopped working. Probably fried the board. Oops :( Lesson learned. This is for very small electrical devices with small current draws in a pinch. Not Greenworks fault at all. It died doing something that it wasn't designed to do. Otherwise, use a more powerful inverter! LOL! FYI, plugged the blender into my Jackery rated for 200 watts and it blended the ice like a champ. Go figure. Read more
