Who’s making good jump boxes?

[M92PV4U]

I don't know who made them, but when we were kids we would get little boxes that jumped. They had Mexican jumping beans in them. Oh, I guess that I answered my question, Mexicans made them.

Sure, I upsated the thread with a hospital grade lithium battery for the same price.

My point is no matter what you buy it's gonna need batteries at some point, I mean that's really all they are is two batteries and some cables.

I’m waiting for one that fits my drill battery system.

if you don't got any broken tools to scavenge the coupler off of, they make the battery coupler thingies on ebay that got wires dangling off them
I use them on my riding mowers, you should disable the charging system though since it might be bad for li-ion batteries

I also only use my crappiest battery for mower starting duty since I dunno if the heavy draw will damage them

This adapter is really nice (best I've found) but isn't available now?

[WTF?]

I bought a jnc 660 4 years ago because it that was the most recommended one. What a joke it struggles to start a lawnmower with a weak battery. I even replaced the battery in it a year ago.
Looking for something thatll actually work.

Something’s wrong with your setup. my 4 yr old jnc 660 started a long-cranking 20hp mower with no battery in it last week. It’ll start a small block with 0 volts in the Battery too, but it does just barely turn over the 8.1 with a fully float battery.

The battery clamps on the jnc are tough to get good connection with especially on lawnmower type terminals and gm Side posts, and that’s really my biggest gripe with it.

Pretty safe assumption it's hard on them but IDK how much a mower starter actually pulls. The $25 walmart U1 I put in everything says 230cca. If you're pulling 150 amps or so out of a 5ah battery thats 30C which is a lot for 18650's.

I have had two Noco's over the past couple years. Both were shit. I will buy an old school lead acid next time.

 

[Ransil]

I've had this one for several years. Has lasted longer than any other I have bought. I've had 3 conventional lead acid ones and 2 other lithium battery ones. This one will start a big block at 20 degrees. My ATV battery wasn't taking a charge so I used it to start it a couple times and now the ATV battery is holding a charge again. I don't get it but I like it.

I got it at Tractor Supply on clearance for 70 bucks too.

I have that one from Amazon under $100
had it for a year finally used it this year working at a resort, jumps cars easily.

used it on one of the delivery box trucks, it was old and shitty every time he tried to close the lift gate it stalled, jumped it 4 times and finally left the jump box on to close the lift gate and he was on his way.

Recharges quickly using the USB charger

good to know, I'll keep on avoiding using my good batteries
see how long this crappy 5.0 that will run a grinder for about 5min works

Pretty happy with this it'll crank a 12V Cummins:

I know a few people who have that DSR. It's really good for the money and the batteries are replaceable.

What the fuck are you talking about?

He said hand crank is superior.

An m18 will work to jump a car battery once. It will fully drain the battery to start a car, but it does work.

FYI, I can't find replacement batteries for DSR's that are any good. I have a PSJ-3612 that needs new batteries but have struck out finding the OEM replacements. The nice part about the older PSJ's is the inbuilt charger. The new ones have sperate chargers that is more of a PITA than I'd like to admit. The clamps on the new ones are junk compared to the old ones as well.

cereal-Ly? Thats big gay. These were older models, and the took a standard Li-on battery used at a few junk yards. They held up well, but cost way more than the ones listed.

EDIT* Here is a link to the better one. IDK if it's the one you are talking about.

I can't understand how capacitor technology hasn't been used for this yet.

they're out there
kinda neat, they usually charge themselves off the partially dead battery, the reduced ESR of the cap bank versus the 'dead' battery means the 12.1v is plenty

ETA: some of them atre dual voltage too, set up with like 30v caps or whatever so that you can hook them up to either 12 or 24v systems

Jump and Carry

Have 2 others, one from Wallmart and the other from Schucks that are shit. Go into some safety mode if the unknown parameters aren't just right and it's done.
Real awesome when trying to start something when it's dark, -30* and trying to get somewhere.

Stupid things together wouldn't even light off my F350 at 70* with slightly dead batteries from leaving a dome light on too long.

The JNC gives no shits about bullshit safeties.

We've got one of those at work, and I have the 12v only with built in 120v inverter at home. They both use an external charger. Why on earth they can integrate a 120v inverter but not a charger I do not know. They do a great job jump starting, but are a step backwards from the previous ones IMHO.

Guessing the junk ones are li-ion. The antigravity one I have is absolutely useless in the cold, which is when most of my dead battery issues happen. Cold weather power is Pb territory, who cares if it weighs a little more if it works.

Best jump pack I've seen was in a service truck. 4 ea 4D batteries . Had Anderson plug jumpers to make it 12 or 24v

If that wasn't doing it, something is catching on fire. But if you can carry 4 of those around, you aren't human.
