Will it START a 454? RYOBI P7101 18V 1600 Amp Jump Starter Review

Stepping out to be the first, the RYOBI Jump Starter delivers 1600 Amp peak output using their 18V One+ tool battery. Other tool companies have labeled jump starters with their logo, but none until now have used their tool battery to power it. Using just their 2Ah 18V battery, you can get as many as 20 jump starts on a single charge. As we show you in the video, it's not really getting the starting power from the battery.

That was actually really impressive. The fact that you can recharge and or replace this battery when you need it makes this a better value in my opinion. The tool itself will not be complete junk in 5 years bc the internal battery is shot. I am surprised that Milwaukee and Ridgid let Ryobi bring this one to market first.

[@-opus]

Agreed, I have a Suaoki g7 plus jump starter that works really well... for a 4 cylinder, I wouldn't be without it, but at some point the battery will fail, it will let me down and it will be e-waste.

[@kartboarder22g17]

only us Ryobi users are cheap enough to not replace our battery when it's on it's last leg. lol

[@762x54rr]

Especially since Ryobi and Milwaukee are owned by the same company they usually release Milwaukee first to get the higher price then let it trickle down to Ryobi brand aka packout vs link

[@NicolaMs007]

agreed, as I am running a 12V setup for lighting on my ebike (similar to the Ariel Rider GRISSLY) with a adaptor and step down converter, I would also be getting one of this tool as I use a lot of power tools with the RYOBI 1+ Battery and am running a 18V 5A/h Battery...I would also be able to jump start anyone on the side of the road with this...i have an inverter in the car where I can charge any battery, and by charging a 1+ Battery on the inverter while the car is in motion, or running, is brilliant

[@electric8668]

I think the manufactuer see this as more of a consumer grade product which would appeal to more customers in general than Milwaukee and Rigid which are considered more upscale. It also falls under the Ryobi 18volt line of products where that battery fits all of their tools.

[@Chris-du7hi]

Well that override button sold it for me. Good test too. The first thing that popped into my head was: yeah sure but its probably too 'smart' to work on a completely discharged battery. Really like how it uses the replaceable packs instead of building one in.

[@MyLifeMyMoneyMedia]

I had a battery tender that was too smart too. Had to force a charge into a dead battery, then the battery tender started to work.

I really love the innovation from Ryobi for their ONE+ versatility. I can use same batteries on multiple things.

That is much lighter weight than my jump starter and it has a built in battery so when it runs down it needs to be recharged I like the Idea of being able to just plug in a freshly charged battery.

2 amp hour doesn't mean it can only deliver 2 amps. It can probably do 20 or so. The capacitors are definitely needed. This is pretty good, a lot of the cheap jump start packs on the market won't even touch a battery with a voltage that low.

[@ss4goku9695]

It can deliver 2 amps for one hour. Cell discharge, on most of these packs is 30 amp Continuous.

[@-opus]

Would like to see a combo inflator/jump starter that can also charge the ryobi batteries via a vehicle cigarette lighter port.

[@stevebabiak6997]

I don’t want to put the inflator in there necessarily, but equipping the automotive tools with cigarette lighter charging is something I would like to see. That would allow for the battery to be topped off for when the tool needs to be used. I have a car with a 120V AC receptacle so I can plug in the normal wall chargers, but that feature isn’t found in all cars.

[@-opus]

@@stevebabiak6997 I believe the inflator and jump starter make sense for piece of mind with a vehicle, I carry a jump starter and have had to use it on more than one occasion, being able to run it off of tool batteries and being able to charge them from the vehicle seems obvious to me, I could just buy an inverter though of course. I was unaware that there were vehicles coming out with ac plugs on them, not that ye olde 120V would be of much use here in Australia, and I guess that is one of the reasons why such things are not that common. It really is a pity that AC was not standardised internationally.

[@mediocreman2]

Kind of. Needs to be a cold day to get a real review.

[@rolandm9750]

I had a feeling this was the case. Thank you for confirming it. It def. didn't make sense a 2Ah 18V battery was going to do jump starting on a repeated basis and be warrantied to do such a thing. But even though it uses capacitors, it does the job which is the main thing. It also means there's no extra wear on the battery and it doesn't matter if you use a 2Ah, 6Ah, or 12Ah battery, all gonna do the same thing, just the larger batteries will provide more jump starts via more charges possible to the capacitor bank.

[@bobbystewart2605]

If the bigger batteries will even fit that is. Looks like it’ll only take a 4aH battery at max based on the visuals from the video. But if it’ll take the bigger batteries, even better.

[@rolandm9750]

@@bobbystewart2605 I believe even a 3-row battery like the 9Ah and 12Ah should fit. If you look at when he puts the battery in you can see the single-row 2Ah is recessed into the unit. There's very likely room there for a battery with two more rows, and the cover closing okay. It doesn't look like it but I think that's because of the way the battery gets recessed into the unit. Still though, won't matter what battery you use, the peak jump power is limited to what those caps can provide.

Big capacitors are great. As long as the battery itself is not frozen, it should work well even in cold weather as the battery will still charge the capacitors (perhaps slower than in warmer weather, but still), which are not that temperature-dependent.

[@jpozenel]

I bought a "Tacklife" jump starter in 2019. There is a dome light in my car if left on will completely run down the battery in a day or two (I don't drive a lot). That happened once when the battery was very old and needed replacement. It happened again just recently with a battery that is less than a year old. Both times I was able to start my car with that little box. (The first time with the old battery, was in December and it was quite cold.) I can't be sure of what state the battery in the Tacklife is in, so this seems like a good alternative/backup plan to me. I have plenty of Ryobi batteries including a couple of those 2Ah batteries that I could easily carry in my car.

I would have like to have seen the before/after of the power bar on the ryobi battery. The tool seems to be promising.

[@stevebabiak6997]

Those five 500 Farad capacitors are very likely connected in series to stack the voltage to over 12V; these series connected capacitors will total to 100 Farads at the two end terminals. Unlike series connected resistors and inductors, series connected capacitors don’t have their values added to determine the overall capacitance.

[@PAPO1990]

I was READY to give you a thumbs down for trying to get it to start such a large engine, and was expecting you to go to something smaller to show it actually work. But DAYUM, very impressed it managed to start that, especially if it hadn't been turned over in months, and with a battery THAT flat. Very impressive.

[@cujoedaman]

Good to see someone that understands the tool they're showcasing. I watched Scotty Kilmar rage on about how useless and "stupid!" jump packs are because it wouldn't start a fully dead battery on a car he was testing it on. He didn't actually READ how to use it and didn't know you had to hit the button to allow the jump pack to charge the battery like you do here. I'm just thinking "and you're supposed to be this epic mechanic that solves all the world's problems?".

Well done video!

[@pg9112471]

I built something like this back in 2013 i used a 6 pack of maxwell super capacitors. An 18v black and deker battery taken apart and cramed everythig in a seethrough polycarbonate box i also built. (Used nichrome wire and a 12v 10amp power block to bend the polycarbonate into two c type halves with 90degree angles) Meassured something like 4w x 8L x 6h. I also used a buck converter to drop the voltage to charge the super capacitors to 13.8v i added a strip of LED lights removable battery cables a socket for 12v accessories with a usb charger to chrge phones, a digital volt display to see the car voltage and the capacitor voltage a charger circuit board for the battery. It worked on most of my cars to jump start, it provided 240 amps for about 3 seconds if it didn't start you would have to "prime" (charge) the capacitors for about a minute. I abandoned the idea because a set of 6 123 lithium something betteries can produce longer cranking and higher amps without having capacitors. I still have it somewhere i used it for a couple seasons to run my zero turn 24hp lawn mower. I bought a lithium something battery that measures about 2and a half wide by 6long by 4 long. I use it in my lawn mower, to jump all my cars when needed. I use it on a DIY dump trailer winch powered. And it's lasted longer than any lead acid battery ever for my lawnmower. It was expensive but worth every penny in my opinion.

[@2down4up]

Very impressive! I would’ve loved to see what it’s actual maximum power output under a load is. I’m thinking it might be higher then rated. The gasoline fueled 4.0 liter V8s I often work on have around 250psi of cranking compression pressure. It takes about 900-1000 amps just to get them started rotating and about 700-800 amps to keep them turning over until they start. I don’t expect this to handle those engines but it would be pretty cool to see just how much it can actually output.

[@ScottyCrawford]

I don't understand your claimed numbers. I wrenched too, and much bigger V-8 gas engines, like 5.4s and 5.7s, didn't need anywhere near 900-1000 your stated amps to start a smaller 4.0-sized engine. In fact, they usually came with factory batteries that were plainly marked as putting out 550-650 amps (cold cranking). Furthermore, they usually started up just fine in cold weather when they got pretty old and were weaker.

[@2down4up]

@@ScottyCrawford So I have a horrible tendency of often times writing WAY too much and making things overly complicated and confusing which I’m definitely about to do again. That said, please allow me to try and explain it in more detail. In the realm of normal automotive and light- medium duty transport and industrial sized engines, physical displacement has relatively little impact on the watts required to turn an engine over when compared to numerous other factors. Even for the last 40 or more years, design, engineering, construction, lubrication, metallurgy, machining and finishing processes have been good enough to minimize the internal friction gain caused solely by an increase in displacement when compared to a smaller engine of identical design. Put another way, with two otherwise identical engines, one a 4L and the other a 6L and if compression pressure is not factored in, then the amount of watts required to rotate both engines will not be massively different. When including compression pressure but keeping everything else identical, the 6 liter should require roughly 50% more watts (i believe) to rotate. However, if the otherwise still identical 4 liter engine has significantly higher cranking compression pressure than the 6 liter, then it will require significantly more watts to rotate. Now with regards to the actual 4L V8 I was referencing, it has a solid 250 psi of cranking compression pressure in all 8 cylinders. I’m willing to bet none of those big old engines you’re referencing had anywhere near that pressure. I’m also willing to bet (perhaps incorrectly) that most of the engines you’re thinking of are single cam 16 valve engines. In addition to the much higher psi per cylinder, this 4L V8 also has several additional sources of friction that I’m willing to bet the engines you’re thinking of probably didn’t have. This 4L V8 has 4 camshafts driven via 3 timing chains pushing on 32 valves with absurdly high seat pressure required by the 7200RPM redline. The cams also drive two high pressure fuel pumps. The engine also has to spin two lanchester balancers, two oil pumps, and a scavenge pump. While the additional friction of any one of these items may be minor, when taken as a whole the additional power required is significant. Now to make matters worse, the vehicles in question have active alternator management. In order to save fuel, the alternator is run as little as possible. This means the battery has even greater stress on it as its targeted SOC is only between 70-80% and more often than not, the actual SOC is much lower. These vehicles can also have a pretty high KOEO draw of about 30 amps or possibly more depending on equipment. When you take the wattage required to spin over an engine with 250 psi of cranking compression, then add in the significant additional load of all the rotating bits, and then subtract voltage due to battery that is never even close to fully charged, and the final result is you’re gonna need precisely one metric shit ton of amps. If the battery is being supported by a fast enough and powerful enough external power supply then the amperage load goes down as there’s more voltage available. But when that’s not the case and you’ve still got the same mechanical resistance to overcome and less voltage to do it with, the amperage must increase or the car won’t crank. My sincere apologies for the overly long response, it’s my hope that I’ve clarified all the reasons why such an insane amperage draw is required to spin over the 4L V8 I was referencing.

[@outdoorjanitor1551]

Looking at a sale flyer for Costco $129, now $99 “Starter, inflator, inverter,” glad I saw this since use 18V Ryobi tools. Wish this had an inverter like their 18v inverter: idea took awhile, way back in the NiCd days, several times when my truck battery was getting weak or I’d left the radio on too long working, I took my Black & Decker 18v cordless tool batteries I then used; at that time it was easy to stick two pieces of solid copper Romex household wire into the battery sockets, even marked “+” and “-“ back then (or did I use a volt meter?) - and after 10 -30 seconds running 18v directly thru the truck battery, the truck would start. Yeah, house wire got kinda warm, and to hook it up backward would have ruined an expensive cordless battery I’m sure… still not decided on whether to buy the Costco box: very slow leak on my trailer so an inflator is tempting; and these days you can make a LOT OF LIGHT in your home during power failures or on the job, with a simple brooding clip-on reflector using 100w household LED bulbs (I lit up a whole house I was breaking drywall out of one night that way with 4 clip on lights, extension cords, and a “China Freight” lighter socket inverter now toast … If the Ryobi 18v batteries had easier to access contacts like B&D 18v batteries did, I’m sure I would have jumped people by now DIRECTLY from the cordless Ryobi 18v battery by now: -but this seems much smarter - and “OVERRIDE” sure DOES SEEM like a good idea. -Modern capacitors: not just for solar yard lites, and Tasers anymore!

Having owned a few lithium ion jump starters that fit in a small box by spare tire under the cargo area of my compact suv I have to say they need to work on the size of this thing. It's a bit large to carry around in this scenario. Edit: 13:36 oh, I see. I didn't expect those large ultra capacitors inside. The small jump starter units use the battery directly and have a relay and a very small amount of electronics.

[@BoraHorzaGobuchul]

For me size is not as important as the replaceable battery and proper capacitors inside.

It's kind of anouying of Ryobi to state EVERYWHERE in their advertisement world wide that you can use your batteries at home on any of their products.

"We don't won't or need a mini 1.5 or little 2 amp battery. We want the product"!

[@TsunauticusIV]

If your battery has a little voltage left in it… these jump packs work pretty well. If your battery is so dead that it won’t even make an interior light glow dimly… they don’t typically work well. I’ve jump started trucks countless times with cordless tool batteries. I made a homemade jump starter kit that fits dewalt batteries. I had a battery in my truck that lost a cell. Wouldn’t start the truck but would turn it over slowly for a few seconds before dying. Well… I used a dewalt battery for 7 months to start my truck. It would do about 10 jumps between having to charge it. Worked really well. I still carry it with me. 😂

I've had several Lithium jump packs that couldn't turn over my 3.6L H-6 boxer fast enough to fire off (or maybe too low voltage to run the computers/relays/fuel pump?) and more recently had issues with a 2cyl Kawasaki riding mower where both a Lithium jump pack and a plug-in-wall-charger-starter couldn't crank it when the battery failed in the driveway. In all cases hooking up a "real" jumper cable started up right away. My guess is my failures were so bad the batteries had no oomph left and maybe what it calls "priming" is hoping the battery will charge enough to help start the vehicle but if its failed badly enough to be able to. What I've usually had is similar to that first test but subsequent tries are no better with a couple turns and then clicking.

What it calls "priming" is charging up the capacitors. While you can charge them faster, super caps last longer at a slower charge rate.

[@joshuaemery6246]

I’ll have to get one

[@chrisvolk106]

Pretty impressive

[@peterlabelle2579]

Tell us about storing with charged battery in car. How does temperature affect performance? Is it safe? Or will it explode in a hot car during the summer?

I keep an 18v royobi inverter with my overnight work trip kit in case my tech runs out of battery. Adding a battery jumper to the boot of my car seems like a no brainer... depending on the cost. It needs to be less than $80 to be competitive with other products that have an integrated batter and a tire inflator as well.

Dude I’m not joking I jumpstarted my truck with an 18 V Ryobi battery only with jumper cables you don’t need that expensive device

[@nigelbarker8726]

Amazing.

[@Arctic5fox]

Are the capacitors replaceable in case it's out of warranty and you want to fix it?

[@chrisbetts6194]

Very surprised it started.

[@mirosawdobrosielski54]

Hey i have been curious where did you buy that starter kit? I have been looking for one online and i cant find a Ryobi one

[@kb9liq]

Dewalt has one on the market that uses their 20 volt battery system Have watch two channels say the same thing that nobody else makes one but Dewalt does

[@superspeeder]

Worst case scenario; bigger than max spec engine, deader than real life battery, still cranks. Nice!

[@JoeRogansGutBiome]

800 CCAs thats impressive for that battery

[@brogren802]

Or you could use the battery itself to jump the vehicle. I've showed a few people how to jump with regular DeWalt batteries. It's not the safest way to do it but it works in a pinch

[@stevebabiak6997]

The Tool Scientist channel has a video where he directly connects an 18V tool battery to a car’s dead battery, and attempts to start the car.

[@brogren802]

@@stevebabiak6997 I know for a fact it will start most trucks if it's a charged and decent DeWalt battery. He had a dead battery so long that he made a set of cables for it out of 12/2 copper wire

[@markrouse9204]

I buying one i have lotxs of there tools already so i could use another another battery and charger. My only concern is how long will the capacities will last

[@alexhall6641]

Ive actually used a makita battery with 2 wires to start a v8 truck and a Kubota mini trackhoe

[@ACommenterOnYouTube]

I use a 20V dewalt 5 ah battery with 10 gauge wire .... works like a charm every time. I am out in the field so i am preparred. Sometimes i work out in the country and there is NOBODY around so if that battery dies, im F'cked until a wrecker comes out

[@vihreelinja4743]

Well i am amazed how well and "long" it cranked that big ass engine. i'm sure with a couple 5a batts that will crank my subie all day :D
