RYOBI 18V AC Adapter Hack

People always ask me if there is a way to run their 18V RYOBI tools off of AC. I recently purchased a RYOBI P750 18V Pump. It came with a 18V 8.3A Power Brick. They use standard Audio XLR connectors. I used a 18V battery carcass from the recycle bin and wired it to a male XLR connector. It works great for low power RYOBI 18V tools. It did not work for high Amperage tools.
Things I used:
* RYOBI HYBRID Transfer pump model P750 ( www.ryobitools... )
* Male XLR Audio plug ( amzn.to/3zDSoeI )
* 12AWG stranded silicon wire ( amzn.to/3OK8BTI )
* security T10 drivers ( amzn.to/2GLxa5y )
* wire stripper ( amzn.to/30LCBbE )
* wire terminal crimper ( amzn.to/3lrpq7Y )

Thanks for trying this Chris. I did something very similar years ago with using an old 18V power supply from either an old laptop or printer and came up with the same results. It worked fine for Ryobi devices needing less power, but it didn't work so well with my power tools. These power supplies just don't have the necessary amperage. I was hoping you'd have better results than I did otherwise I'd run out and buy that power supply. Thanks for trying.

@Derek xPaPaDx Frampton You must not have read my comment because it referred to my partially successful attempt doing this many years before this video came out. It was done with an 18V PS with a lower than necessary amperage for power tools but enough for flashlights.

@richmorin424 Год назад

I measured the current draw on a couple of Ryobi ONE+ tools. The wet/dry vacuum draws 12A. The miter saw draws 24A on startup, but goes back down to about 15A when spinning (but not cutting). I suspect that a 30A power supply would be about right. I hacked up an old battery to act as a male plug, but I'd really like to find a plug that has more robust wires, etc. Currently looking at power supplies...

I wonder if that would work for the little Air compressor..

@yanmak2363 Год назад

This is exactly what I wanted to do when I realised my light wasn't corded. Thank you sir. Should you add a fuse to this setup, as a precaution?

@Wilverine99 28 дней назад

Has anyone made this work for the cordless tools? Would love to have the option to plug-in and maybe charge batteries at the same time on the job site!

@kingboy1959 Год назад

I wonder if that would work on my Ryobi 1 Gal. Compressor? I tried it yesterday for the first time, I goes through battery's pretty quick..

I want an ac/dc compressor as well.

I wish Ryobi would sell a purpose built adaptor like this to run their cordless tools. The only cordless tools worth a damn to me are drills & drivers anything is else is garbage imo and I'd rather have a corded version. Unfortunately I received a cordless Ryobi trim router for Xmas last year, it's a nice trim router and it definitely better than the other trim router I have from Harbor Freight but its totally useless to me bc it's battery powered. I have batteries but when I want to use it I have to wait to charge a stupid battery first. An 18v DC to AC adaptor would solve all my issues.

@Benmarks 11 месяцев назад

why wouldn't you keep the battery charged?

@MichaelLeeHensel Год назад

I was super excited until the very end when you said it won't work on a drill or anything other than low power tools 😔

@lostandfound6501 11 месяцев назад

It will work on the bug zapper probably which is what I'm looking to build one for.

@practicalmedicine4359 Год назад

I have an old ATX power supply which claims to be able to supply a LOT of amps. May try this with that supply as the computer is dead.

@SuperMIKevin Год назад

What is the model number for that power supply?

@coryulrich6489 2 года назад

Hey Chris, this could work with a laptop charger too. Can you do a video on that? I've seen some people connect like 5 of them in parallel

@MrJob91 2 года назад

How is the output voltage regulated if you combine 4 together?

@PurpleRhymesWithOrange 2 года назад

Thanks I have thought about this for years. Tried to build one once but could not get enough power from it. Then again that was trying to power the drills about 8 years ago.

@cameranmanner4701 Год назад

I was thinking making a adapter for a charger. Charge a 4amp battery in 30 m or a 9amp battery in a little over an hour. What's your oppinion on using 2 power supplies in parael to increase current output for tools that require more power?

@SerendipitySue Год назад

You don't want to charge batteries too fast, it will ruin the battery or cause safety issues

@0ffGridTechClub Год назад

Awesome !

@KoopaWhat 2 года назад

Any thoughts on trying the power supply from the Ryobi P4002PS Drain Auger it shows a 18v DC 6A output? Was hoping their new Miter saw would be Hybrid but unfortunately it isn't so definitely looking for ideas.

@SerendipitySue 2 года назад

That's even less power than the pump power brick... and that wasn't enough to run high amperage tools. I doubt the 6A powersupply would power anything more than the fan, radio, LED light etc.

@KoopaWhat 2 года назад

@@SerendipitySue just re-watched your video, for some reason I thought the pump power supply was 3 amp.

@tomackerman4089 2 года назад

So this device makes it so you can use either battery power alone or use power from an outlet? Like how a laptop or a smartphone can run on just battery power or on power from a wall outlet when it's plugged into an adapter? That would be cool if your device does the equivalent for 18 volt Ryobi batteries and tools.

@SerendipitySue 2 года назад

You can use 18V batteries with your Ryobi tool, or for some of the lower power tools you can plug them into AC

@antonioreyes421 2 года назад

Wow, this is awesome.

@jimstand 2 года назад

Hi Chris. Any chance you could come up with an adapter so that we can use a Harbor Freight's Hercules 20V 12AH battery on a Ryobi tool? Harbor Freight is selling them for $140. This is half the price of a 2 pack of 6AH Ryobi batteries.

@SerendipitySue 2 года назад

When I tested knock-off Ryobi batteries, they lie thru their teeth. I never got close to the Watt/Hr or Amp/hours listed. They also use cheap no-label, low amp batteries. I decided to pay extra and not worry about my house burning down. I don't have any Harbor Freight batteries. It might be a fun project building an adapter... Do you know if the BMS is in the battery or the tool? thanks for the idea

@SerendipitySue 2 года назад

Looks like someone makes one already: www.ebay.com/itm/144567582700

@jimstand 2 года назад

@@SerendipitySue The Tool Bear took one apart. The 21700 batteries are Samsung but the BMS board looks really small. They are nothing like the circuit boards in a true 20V Ryobi battery. The tear down video is on the youtube channel The Den Of Tools and the video was posted today, 8/26/2022 . The video is only 3:28 in length. These are HF batteries for the Hercules line of tools. Thanks Chris.

@jimstand 2 года назад

Thanks. I searched on eBay and Amazon and could not find one.

@tomackerman4089 2 года назад

Does this device let you charge the Ryobi battery and use it at the same time?

@piousminion7822 6 месяцев назад

Amazing find. That power supply is $40 on eBay, but given what I've learned here I intend to buy a high amp power supply and use the same XLR plugs. Great vid. :)

@OMY2FYB 3 месяца назад

can you help me find a link?

@jamesarnold6059 3 месяца назад

Not sure if you consodered the p3320 fan w/ a 110v a/c male plug coupled into a standard 18v dc female battery socket. It seems like it'd be less work & cost

@SerendipitySue 3 месяца назад

Several RYOBI tools allow you to plug them into 120VAC. They do not charge the battery. They just convert the VAC to DC of the appropriate voltage. They are typically low power devices. I suppose you open the fan up and tap into the converted AC. The fan would then have to have another cord with the male battery end. I don't have that fan, but I do have an LED light that takes batteries and AC. I'll have to take a look!

@ewicky 2 года назад

I wonder if some capacitors or super-capacitors hidden in the "battery" could soften the current spikes from drills and other higher loads, to make this power supply setup compatible with more tools.

@SerendipitySue 2 года назад

The ryobi power brick seems to have a large capacitor in it. When you first plug it in, it takes a couple of seconds before the green light goes on.

@jasonbroom7147 Год назад

Very cool stuff. Something I think is great about your channel is you're constantly exploring the "what if" scenarios of the Ryobi ecosystem. I'm not a fan of using a 110v step-down converter to power lower-amperage DC devices, but knowing you could if you need to is still great information. Thank you for continuing to think outside the box and post cool videos like this. :)

I don't have the capability to make/sell/support things. I put the 3D print files out for free. There are Internet companies that will print models for you
