Maxing out the Ryobi 300 Watt Power Source 

I would think that a coffee maker would draw over 300w. I'm impressed.

I POWERED MY FRIDGE ON THIS UNIT

Thanks Andrew. I was looking for some tools tonight that would work. Put it together soon.

i just got one of these today and i already had a fully charges 40v so i tried my corded dewault drill and the drill will start briefly (no load) but the red indicator light came on and it stopped working. hit the button and tried running the drill really slow and it ran for about 5 seconds and the overload came on. i'm aware the drill is probably not the intended type of tool for this device but i do have an issue with it the inverter, that being that the internal cooling fan did not come on while doing some other tests that were more in line with what it's supposed to operate. it's an issue because the battery and inverter are heating up and it smells like overheated electronics. i had the device lying flat so the fan vents were exposed so that's not the issue.

It must be heat related. I have noticed the fan running in both positions.

It would vary based on the fan type and how may have power it used. If you have an example, I could tell you.

Pulling 1 amp on a 4 amp hour battery you should be able to run the fan for approximately 4 hours

It wont run at 300W ... Maybe 250W and then it shuts down

I will see if I can set up a test for it.

@@zacktalksshopbside i used (2) 150W bulbs. One direct plug in for 150W and the 2nd one i put on a dimmer switch to control its brightness. As i got between 250 and 260W it would cut out. Had it swapped out 2 times, same issue on all 3.

​@@zacktalksshopbside When Ryobi quotes a 300W capacity, they probably mean that the device has a conversion inefficiency, using up to 50W for losses, and 250W for actual power delivered. A controlled test would test the converter with a 250 W load, and time how long it exhausted a 4AH, 6AH and 7AH battery. As you noted, it may kick out in under a minute when it gets near 250 W, so it would be interesting to try a 225 W load.

Multiply volts by Amp hours to get Watt hours. You can use this to get a consistent unit of measurement for comparisons. Figure 80% energy transfer due to internal inefficiencies in the inverter and you will be close enough. A 4 Amp hour 40v battery (actually 36v, 40v is the peak) can charge roughly 1.6, 4 Amp hour 18 voltage batteries. 36x4×.8=115, 18x4=75. 115/75=1.597.

Did you figure that out?

@@adamkershaw2314 I haven't gotten around to trying it yet. I'm sure there is a way.

I doubt it. Might run a smaller pump, though.

🤦🏽‍♂️ a sump pump uses 600 Watts for a 1/4 hp motor. 🤦🏽‍♂️

@@ACommenterOnRU-vid Thanks, I figured it was too much.

I'd suggest something like the Jackery or River from Ecoflow. These solar generators can charge up much faster and have much greater energy density than these inverters. The Ryobi inverters also produce a Modified Sine Wave instead of Pure Sine Wave, making them unsuitable for sensitive electronics.

@@dogishappy0 this model is actually pure sine wave. It's one reason I bought it. I also have Bluettis and a gas genny. The Ryobi and Bluettis are for my electronics

@jules6499 all I know is the smaller Ryobi inverter for the 18V batteries almost burned my house down when I used it for an electric blanket during a power outage. Now if I need to use a Ryobi inverter for anything sensitive or heating related I'm plugging into a UPS powered by a Ryobi Inverter.

This one seems to do better than the ones you tested.

@@zacktalksshopbside how much power did you get thru it ?

You should be able to charge a cell phone several times I would think

It would have to be real small, most of the ones I know of would be too high of a wattage.

@@zacktalksshopbside thanks! Cheers

Do you have a voltage and amp rating for a particular projector?

@@zacktalksshopbside Is 12 v 3.5A

@@fjts666 if you mean 120 volt, then no. If you mean 12 DC then I would use a battery.

It depends on the wattage. My gut says no, but I am not sure.

I see there is an M12 power source that can charge their batteries as well. That would be cool to test. I don’t think it has a lot of output, though.

@@zacktalksshopbside funny would be seeing Ryobi charge a Milwaukee & Dewalt at one time. 😂

@@OcRefrig That would be funny. I should get the Hart inverter and charge M12 batteries

It will not power a space heater. I just put a multi plug in it
