Portable Jump Starters
« on: January 29, 2017, 10:54:47 AM »
Anyone have any experience with portable jumps starters? I've looked at O'Reilly's, Auto Zone, Wal Mart and Harbor Freight (the home of cheap ass tools) and some I've seen look sketchy and others look reasonable with some quality., but I don't trust the online reviews.

Oh, this is for automotive applications.

Anyone? Thanks!

Cheap and it does what it's supposed to do.

the little lithium ion ones are amazing. I'll look tomorrow to see what brand we have at work, but it's small (entire package is the size of a cereal box) and will do everything from charge a phone to start a diesel pickup.

I wouldn't touch the lithium jumpers with a long pole.  Lithium is not optimal in combination of high draw/cold temps where I would most likely be using a jumpstart.   If you have 20-30 minutes to wait around and trickle a charge into your ailing battery, they would probably be okay.

I buy a cheap device that has all the features I need (light, compressor, usb) and simply buy and install a new battery in it every couple of years.  Lead acid gives you high discharge rates and decent cold weather performance.  The technology is pretty solid, and they're cheap.

I'm pretty sure it gets cold where Black Hills is.

That said, I have no horse in this race.  8)

I've got a yellow gel battery powered one. Curiously, no make on it but it's worked well for years.

The unit is compact enough that it stays inside where it is warm most of the time.  I haven't used it much but others swear it's great??

I just throw a new battery in the vehicle every 8-10 years.


If I were buying something today I'd get one of the little lithium jobs.  They fit in the glovebox or under your bike seat and are fine for their intended use.

Thanks everyone. I'll do some more research. The lithium units are a little pricey, at least the ones I've seen.

I've had to use one of them a few times. Don't know the brand but they work.
I'd tried to jump start using another bike and that didn't work at all.

You can find some cheap Lithium Ion ones at wally world.
Ride safe!

I thought the same thing when I first heard about them.  But there are lots of glowing reviews.  I'll buy one when I come across a good deal on a proven brand/model or a really good deal on a good spec no-name one.

I have a Pep Boys one I got on sale. Works fine, holds charge a good long while, and includes an air pump and work light. I recommend.

'Splain me...
1) Is it just that I'm lucky, and most people routinely have dead batteries? Other than as a bailout while in Lower West Bumf*** Egypt, why do I need one of these? I carry a set of jumpers that were used maybe once in I forget how many years.
2) IIRC most automotive starters need triple digit amps to fire a motor. OK, LiON's (or however it's spelled) are good for high current, but isn't this expecting to get 10 pounds out of 5 pound box of rocks?

Are you part of the solution or part of the precipitate?

I also have very few battery problems with my personal vehicles, batteries typically last 10+ years. My work truck is another story. I rarely get more than a couple years out of them, but 2-way radio, phone/I-pad charger, AVL transmitter, strobe lights, etc. apparently take a toll??
as for motorcycles I've always just push started them if the battery is dead. Yes, even the FI ones and the ones with a slipper clutch...

This is for a 21 year old truck that seems to have lost its cold start ability in temps below 40° F. I bought a Schumacher do everything jumper with compressor, 120V AC outlet, light, 12V DC inlet/outlet and 4 USB ports. Works just fine, except it can't make coffee and looks appalling in a French Maid's outfit.

Anyway, it's off to the shop to address the cold start issue, a minor coolant leak and have the clutch looked at. I could do most of this but my lease agreement forbids auto maintaince in the parking lot. Most of my neighbors are really cool but there are a few who wouldn't hesitate to rat me out, and then the nice lady in the office would have to give me a warning and fine me, even if she would be apologetic about it.
