Ryobi Cordless Drill Charger

A drill with a keyed chuck. I still have the 1/4" B&D I bought in

Think about it. Have you ever seen a commercial drill with a wimpy keyless chuck?

It often makes me wonder why it isn't so obvious to everyone else....

Nor do I, the reason being I have enough junk, and if I were on eBay, I'd only end up with more.

(viewing picture) Yeah, that's the one. I have friends who have an eBay account, so maybe they can ask about that.

Thanks.

A label on the drill itself says "Use with Charger No. 7221001." When I enter that p/n at

The tool is Chinese-made. I scavenged a Chinese-made Ikea lamp a few weeks ago with a bad crimp inside. It looked like a good crimp, but the meter said otherwise. There's a lot of brand new-looking Chinese stuff in the trash around here. All of it is so cheap that people throw it away rather than attempt to fix it.

Walk around Bed Bath & Beyond some time. I don't think there's anything in that store that's American-made.

I still have my 1/4" B&D drill that I bought in 1969. I refuse to buy Chinese stuff.

Thanks to everyone for writing.

Looks like this part is carried by M&D Mower[1] and goes for $5.91. At that price, you may as well just buy a new one. I've purchased Ryobi parts from this dealer in the past, and had no problems with them.

Or just call M&D and ask them to read the specs off of the charger. ("I just want to be sure it's the right one for my drill..."). (c:

go to dallas.craigslist and search ryobi drill. someone there is selling one including the case.

I don't know what you'd make the windings out of to achieve this - copper will melt. The cheap and nasty way is a series resistor.

Really? I have an elderly miniature cordless drill which has given sterling service. Their current stuff seems about par for the course at the price.

I would trust the part number given on the exploded view documentation for this drill rather than the label on the drill.

Miniature? Model #? Pics?

Better get the OEM replacement for a certain match. Problem is, the specs on the charger unit specify output volts, amps and AC or DC but not the internal resistance of the unit which can vary. If you get one that seems to match but has low internal resistance, it may not properly taper off the charge at the end of the cycle leading to an overcharge and possibly battery damage. The quoted price is about as low as you are apt to find anyway.

Similar to Dremel, but cost rather less - and I'm not sure Dremel had a cordless option at the time I bought it from B&Q, over 5 years ago.

Can't be bothered - do a Google. ;-)

It's had heavy hobby use and even the batteries lasted well. They are AA size so cheap and easy to change.

Dremel has had a cordless hand grinder for more than 5 years.More like 10 years.

harbor freight has one that runs off 12VDC,comes with an AC adapter,or you can run it on your auto battery.(or 8 D cells)

the cheaper cordless tools(like Ryobi) use a plain transformer charger,not some regulated "smart" charger. And you CAN overcharge your packs with them.

Some folks use a simple timer to shut off the charger after 8 or 16 hrs,whatever's called for by the particular tool.

the better tools use a one-hour or shorter fast charger. They also have a temp sensor in the pack,or use an IC to monitor battery voltage to determine when to stop charging.

And five years is hardly elderly.

My Black & Decker AC drill turns 32 years old come December, a significant percentage of my life, and the only upkeep it's needed was replacement brushes about 1990.

Even my Sears "rotary tool" is at least 15 years old, and I wouldn't call it "elderly".

They weren't around in the UK when I bought the Ryobi - or at least not in the DIY stores.

Err, something that needs 8 D cells isn't in the same class. This is a small light high speed drill. I mainly use it for PCB work. It uses 4 AA Ni-Cads and is only about 9" long - little bigger than a mains Dremel.

Very much so if they say something like a four hour charge. At worst, some have only a series resistor to set the current - even although they provide a pretty LED to 'show' it's charging. The series resistor idea isn't quite as bad for a lower charge rate like say overnight - but can still cause damage through gross overcharging. However, as the cost of 'smart' electronics comes down, some cheap ones are providing it. If only to cut down on warranty claims.

But these aren't cordless. Most inexpensive cordless tools get junked when the battery pack fails as a new one is often priced at more than the complete unit - as are replacement cells.

I can beat your B&D - mine was bought in '62. It did have a factory overhaul some 10 years later then got a more gentle life used only in a drill stand. Don't think I've used it since I got a pillar drill - these days you get used to soft start vari-speed mains drills which reverse, etc.

I have one of those. I got it used at least 17-18 years ago. At that time it had done hard service in a luthier's shop and needed work on the speed control and new brushes. Sears had a hard time coming up with a diagram, but finally was able to order parts for me.
