Convenient and easy to use
Since I already had the 40 volt battery from something else I previously purchased, this seemed like the most economic purchase for me in terms of inverters, it's only 300 watts but in my opinion it's awesome I actually can use it with my blow dryer as long as I hold the cool button which means it's great for camping etc actually it takes half of the battery just to charge my phone and that's not good but , but it has so many great uses it's very small so it doesn't take up hardly any room, I highly recommend it, the only reason I only gave it four stars is because when you use it it puts off a slight smell of Grease which is not that appealing.

Works well, but packaging is garbage.
They should not use this type of hard plastic packaging.

    Super easy to use. The battery charges very quickly. Instructions are easy to follow. The generator is very easy to carry and use. Lights on the side help you know the status of the charge. The light on the generator is a great feature to use especially when there is little to no light.. I was very impressed to be able to bring to the park for a family outing and allow people to recharge their phones for more photos.

    We live off the grid on nothing but solar and wind energy. I got this inverter-generator to help with those times that we do not have enough electrical power to run my laptop for more than an hour or enough power for my wife's oxygen concentrator. The latter is a low energy concentrator, but it still takes enough power to make it difficult without a backup plan. This Ryobi model works perfectly for both. It powers up quickly with the charged battery and lasts quite awhile - longer for the laptop than the concentrator, but still long enough for my wife's use.

    This Ryobi battery-powered inverter will be a valuable tool during times that electrical power is unavailable and you need power of up to 300 watts on-the-go or during an outage. This price is for the tool ony, the battery and charger are sold separately. This is great if you already have other 40V tools because all Ryobi 40V tools, batteries, and chargers are compatible with each other. With a charged battery, you can run or charge small electronics or you can use the built-in LED task light. It has a USB-C port, a USB-A port, and a 120V outlet (using 2-prong or 3-prong plugs) on the side, along with a button to turn On/Off the external LED task light on top of the unit. When this button is pressed twice, the light will strobe. There is also a battery status display on the Power button that glows Green for normal, Yellow for low, and Red for an overload. I love the folding handle that makes it easy to carry from one place to another and the foam padded surface protectors on 2 sides. Of course, it is not designed to run heavy power tools or large appliances , but it certainly can run phones, small laptops, small fans, LED lights, radios, and many other small electronics as long as the wattage is below 300W (it easily powers my 100W can opener). It will also run or charge your USB products. The length of running time will vary depending on AmpHours of the 40-Volt battery you are using. When the internal components sense that cooling is needed, a fan will automatically run to cool it. Just check the wattage of what you intend to plug into this inverter before trying it (Amps x Volts = Watts). As I received this tool for review purposes, I was sent a charger and battery. The battery charger OP403 is like none of my other chargers - I love this one! My old 40V chargers are huge, but this is compact (only about 5"x3.25"x1.5") and not only charges my battery, but it is also a portable USB power source & charger with status lights. I like that the Ryobi batteries have an on-board fuel gauge. The 40V battery that is needed for this tool is currently available for purchase in 2.0Ah, 2.6Ah, 4Ah, 5Ah, and 6Ah sizes. This is just another of the great products from Ryobi. The only thing I don't care for is the plastic packaging because opening it is not easy for these aging hands. Ryobi offers a no-risk satisfaction guarantee and a 5-year warranty.

    Since California is intermittently shutting off our power due to their new wildfire public safety...
    Since California is intermittently shutting off our power due to their new wildfire public safety power shutoff it is becoming more and more important to have back up sources of power. This Ryobi 40 volt powersource 300 watt battery inverter is absolutely perfect for these types of situations and more. With its (1) - built in USB C port, (1) - USB A port and its (1) - 120 volt outlet it is perfect for charging or powering cell phones, tablets, laptops, fans, lighting, radios, small t.v's. and anything else that doesn't exceed its capacity. Since it has pure sine technology (clean electricity) you don't have to worry about it damaging your sensitive electronics. Some of the contractor grade generators out there don't put out clean electricity and would damage your electronics if plugged into it. I now have (4) of the Ryobi 40 volt batteries in different amperages (Ah) ratings from all my outdoor power tools. With these batteries fully charged and this inverter I will be able to power and charge all my small electronics as needed. With the built in LED light on the inverter you can move it around the house providing both light and power which is very convenient. With the built in handle and the anti slip material on the bottom and the back of the inverter it is very well engineered. All in all Ryobi did a fantastic job of adding yet another piece of equipment to their great line of tools. This inverter comes with a 5 year limited warranty. I have had Ryobi tools for the last 20+ years and the only problem I've had with one of them was the trigger on my leaf blower which they fixed for free. All in all Ryobi makes great tools and I'm excited to see what they think of next.

    'RYOBI's 40-Volt Power Source provides convenient, on-the-go power both on and off the jobsite.' Could of not said it better myself, here with 300-Watt of continuous output, we mainly keep them on hand for our great Northwest weather and power outages. Powering everything from a laptops, to charging the cell phones and as back-up for cable zone gain power splitter. The external LED light may be one of the most used features for us for quick work light around the home and during those power outages . Here we have our Hybrid fan connected and our charger unit with it's own USB port. The inverter has a USB-A, USB-C and one 120-Volt wall outlet for reliable power. Use any RYOBI 40-Volt batteries, and a 5-year warranty

    This was designed by Ryobi for powering or recharging small electronics for a few hours during a power outage or at a location where electricity to do so is not available such as camping, etc. It is not intended to be a long term use item or to supply electricity to saws, drills and other power tools. But anything that does not exceed the 300 watt limit of the inverted generator can be powered. Just keep in mind the amp hour capacity of the Ryobi 40 V batteries that you have or will purchase and the power consumption rating of what you want to power and you will know if this is something you would like to have around. It has 1 USB-A outlet, 1 USB-C outlet and 1 120-Volt outlet and a very bright light on the top just under its folding carry handle. This light can be on steady for use as a light or flashing as in use for a signal lamp. If you dont already have any of the tools from Ryobi that use the 40 volt batteries, you will need to purchase the battery or batteries and charger for them in order to use this device. We have two of the Ryobi 40 volt mowers and have a few batteries and chargers already, so we were ready for use right out of the box. This should be more than enough power to keep my modem and router powered for a while in a power outage.

    The Ryobi 300 Watt Battery Inverter is perfect for anyone that uses electronics, laptops, tablets, cameras, or phones extensively, and does not always have shore power available. It uses any of the Ryobi 40-Volt Rechargable Lithium-Ion Batteries as a power supply, and provides a standard a/c outlet with pure sine wave power up to 300 watts. It’s also equipped with one USB-A and one USB-C outlet for charging the most common phones, tablets and similar devices. I have the Ryobi Battery Inverter teamed with a 4 amp-hour 40 Volt Battery, which will provide 15 phone charges on a single battery charge. This battery inverter will be extremely useful while travelling when shore power is not always available. Highly recommended!!
