RYOBI RYi300BG 300 Watt 40V Power Source – AKA Battery Powered Inverter Generator

7/24/2019 Lot’s of readers have been patiently and impatiently waiting for the new Ryobi RYi300BG 300 Watt 40V Power Source and have wondered if it was ever going to come out. It appears we’ve found out why it’s taking Ryobi so long to release the 300 watt version and that’s because they made some changes to the unit as seen on the HD website, spotted by DrewBHAM of course. Overall the unit looks very similar to the original images however with a few slight tweaks here and there.

The biggest changes come to the control panel. Starting from top to bottom, the light button is now larger and with a four sided shape. The original design had a very small circular button that looked to be hard to press with normal sized fingers. The new larger light button should be much easier to press. The power button has a similar revision in which it is now larger a rectangular shape instead of a circle. The original button didn’t look too small to pose an issue however the larger revision is welcome by me nonetheless. The dual USB ports are still present with USB-A untouched while the USB-C port now uses the smaller oval shape. The 120V AC port receives only an orientation change and is now upright instead of being on it’s side as seen on the original design. The LED lights that were located on the top of the unit just below the handle also get a change as well and now feature a single LED light instead of two. The next change I noticed was a very small one with the omission of an exposed screw on the side where the handle attaches to the body.

As far as features go, all seems to be mostly the same with the 120V AC port having the same 2.5 amps, with the USB port A up to 3 amps and the USB port up to 2 amps. Looking over the manual, it states that this Inverter ouputs pure sine wave meaning it’s compatible with a wide range of corded products that require pure sine wave to operate properly.

While the manual omits the “generator” portion of the name/title, the HD listing still shows this Ryobi 40V 300 watt inverter power source as still being called an inverter generator. The price is still the same at $99 as a baretool and it’s still unavailable for purchase at time of writing however it should be available for sale soon. I don’t have an official ETA from Ryobi but will update as soon as I hear from Ryobi.

Previous Info From 4/8/2019

Over a month ago (2/22/19) I wrote about the RYOBI RYi300BG 300 Watt 40V Battery Powered Inverter Generator and thanks to DrewBHAM, he found the manual to this new inverter and it reveals a couple of new interesting facts about the inverter with one of them being a new name change, or possible name change. The manual calls it a power source, so it should read as the RYOBI RYi300BG 300 Watt 40V Power Source now although I am not sure if the difference in name in the manual means the product itself will get a complete name change. It makes sense that they may have changed the name and omitted the generator part of the name since it’s not a generator at all since it’s not producing “new” power. They also may have changed the name to make Drew Morgan happy since he was very vocal against the “generator” portion of the name 🤣.

Older original design

There wasn’t too much info regarding what type of waveform they used on this inverter but now we know that it’s outputting pure sine wave which is a big deal as it’s now compatible with more AC products that require pure sine wave to run. Also they added a USB C along with the USB A up to 3 amps via each USB. USB C is important because it allows the ability to output up to 20V at up to 3 amps however the USB ports share internal circuitry. If USB-A is in use, USB-C will supply 5V
output only. The single 120 volt outlet is only 2.5 amps.

Whats interesting about the new RYOBI RYi300BG 300 Watt 40V Battery Powered Inverter Generator – now known simply as the Ryobi RYi300BG 300 Watt 40V Power Source is that it’s Ryobi’s answer to Ego’s Nexus inverter. It takes Ryobi 40V batteries to put out 300 watts of AC power for low consumption household appliances that plug in through the single 120V AC port. It also includes two USB ports, handle and a dual LED light making this a great handy little unit for camping. It will be available soon and it’s going to retail for $99 as a baretool.

A huge thanks to DrewBHAM for spotting and sharing!

Very interesting!

Do you know when RYOBI will be officially announcing these two generators? Also, any word if comparable products will be coming to Milwaukee or RIDGID?

This version and the 1500 watt version: both better be true sine wave output. A significant design “whoops!” on products available to date (Dewalt…E-GO…looking at you)…they are modified sine wave output…a marketing smokescreen term for square wave. Most motors and also the switching power supplies used in nearly all electronic items today are not amused with “modified sine wave.”

This version makes a lot more sense. Price is right and you’d get about 30min at 300w.

I have to agree that it SHOULD be pure sine wave but at this price, I’m betting it isn’t.

It is still REALLY dumb that they’re trying to call these generators. Someone at Ryobi Marketing needs to be fired. I can guarantee anyone who reviews tools and isn’t a total shill is going to make fun of this.

The “brains” behind a pure sine wave inverter have been highly integrated into module form (IC chip sets) for a few years now.

https://www.amazon.com/WINGONEER-Inverter-EGS002-EG8010-IR2110/dp/B077VKFP5K/ref=sr_1_3?rps=1&ie=UTF8&qid=1550867745&sr=8-3&keywords=Pure+sine+Wave+Inverter+Driver+Board&refinements=p_85%3A2470955011

If a company wanted to, and the in-house engineering team had the talent, a pure sine inverter can be a low cost design. But, typically these types of “accessory” products are outsourced designs, and the engineering teams behind them are of varying expertise.

Any idea when will these be available.
Don’t want to settle for something else

I have tried “modified sine wave” inverters, and many devices will NOT work with this kind of power. I recently acquired a Ryobi string trimmer with 40V power, so I could use this! Hope it is on sale soon.

Does anyone know if this is actually 300 running watts or just 300 watts at surge? Also how did you get a manual to this product if it is not on the market yet?

The 150W 18v version came out after this is already for sale yet this one is still not available. I am still waiting for this 300W version to come out.

TYPO …
This is NOT 300W from a 40V 5aH battery, the battery can ONLY supply ~200W/h … The outlet shows 120V at 1.5 amps which is 180W …
You CANNOT get 300W from this battery in any way shape or form ..

WH stands for watt hours, which is a capacity rating derived from amp hours X voltage. The actual power output can be far greater than the WH. So any Ryobi 40v battery in good condition should be able to output 300 watts, with runtimes varying based on the individual capacities of each battery. I hope that clears up the confusion with the watt hours.

Looks like Home Depot was listening to you Javier the Home depot site listing for the Ryi300BG is now live and they show them in stock at my local stores and even seem to have sold one at a near by store. It looks like most stores got 3 of the units in, they may not be out on display yet so you may have to ask around at your local store to get your hands on one. The strange thing is that they don’t seem to be available for online order right now.
