Greenworks 40V 300W Cordless Power Inverter IV40A00

I'm sure this unit works just fine, so didn't want to leave a one star review, but beware that this will not work with Canadian market batteries. I wish I would have read the reviews beforehand, as several commenters have also mentioned this. Seller did however graciously offer a full refund with free shipping, so kudos to them.

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!

Nice to have a way to use my 3 existing greenworks batteries to charge phones etc in a power outage (which we're told to expect winter 22).It's pricey for a little bit of peace of mind though

The media could not be loaded.  Après avoir lus les commantaire j'ai quand même décidé de l'acheter, lorsque j'ai reçu le produit j'ai fais quelque modification du connecteur de branchement puis changer de place le fils central pour l'autre connection. J'ai remonté le tous et ça fonctionne avec les batteries canadien. Je sais que je mes fin a la garantie mes je m'en fiche. L'avantage de connaître l'électronique.

This unit is great. I’m able to use it to power lights, charge phones, and even ran my laptop on it for nearly 3 hours. I used my oldest and weakest 2.0 battery. My 4 and 5.0 batteries will be amazing on this. This product keeps me from having to get my big Jackery generator out for short power outages.
