The little tiny one are only good for a quick extra boost of power.
if the main battery is really low or it takes a lot of cranking to start vehicle they suck.
I carry the JNC listed above.Stays charged in truck for weeks and I can jump more then 1 car in between charges .

The quality of the jump box is directly related to the battery it uses. Better batteries cost more.

The words "quality electronics" and "Harbor Freight" rarely belong together. At least in my experience.

I have the Cobra with the air compressor in it. It's not so good at jumping but the compressor will run for a long time to air up tires. Not long after I bought it the compressor would run but not pump air. I took it apart to find that the plastic "gear" had spun on the shaft. I just drilled a hold thru both and pinned it in place and it has worked well since. It will jump my boat, and that's what really counts.

​​What are "jumper cables"?

I’ve gotten two from Harbor Freight, the first lasted just past the warranty date. I also have a duralast from Advanced Auto Parts. Much better quality..

That's what replaced push starting a car. Kind of like the 8 track of power transfer.

Talking about the little lithium boxes. I have returned 2 junk boxes to Costco. Customer service person told me they have taken a ton back.

I now have three different Weegos. Boat and 2 cars. They seem to be holding up well. The boat version has probably jumped 5 boats last year (never done). Who knows if they last.

I do recommend the NOCO ones as well. Kinda wish I had bought the larger 150 size.

I have the BASAF one that you reference from Amazon. Bought it maybe 4 months ago.. My wife's car has some weird problem that causes it to not start on a fairly regular basis. No one seems to be able to figure it out. Mercedes dealer and 2 independent shops. Anyway, she uses that box to start her car probably at least once a week and sometimes probably 3-4 times / week. Works every time. Quite happy with the box and I also have a diesel truck that I hope it will start also - why I bought that unit. BTW, her car is a V-6 diesel (ML320CDL). We've only charged the thing maybe 3 times?

I’ve made this comment several times on here- I would not in a million years use a harbor freight anything as a safety device...

in other words if you put one on boat to take offshore it completely defeats purpose to have it as backup. I love HF but not for this...

You guys crack me up! Just replace the silly batteries at the 1st sign of failure.... or replace once the stated battery life has been met. If you have someone that insists on leaving things on to run the battery down, give em' a set of jumper cables and be prepared to go get them; they're "causing" premature failures by letting the batteries run all the way down. It'll only take a time or two ...or maybe three for the most dense to get it.

I'm not using jumper cables with my car if at all possible. (1) I don't need a fried electrical system because their's is shorted, and (2) I don't need scratches on the fender from the cables. If you don't care how your car looks, go 'head.

Again...what are these "jumper cables" everyone is using?

They only work as intended if they are fully charged.



So there's another device to worry about.

That's not quite true. Actually the instructions suggest that you charge to 50% capacity to prolong battery life. It says there is enough charge at 50% to do several start cycles; and I can attest to that, having used mine after a year in the back of the car since the last charge.

No need to carry a spare tire as long as you replace your tires at the appropriate interval and make sure you dodge all nails.
No need to carry jumper cables OR a jump box as long as you replace the batteries at the appropriate interval.
No need for fuses or breakers because you should never overload your circuits.
And since this is a boating forum, let's get rid of those pesky life jackets and first aid kits.

Only the most dense (aka we mere mortals) find themselves in circumstances where any of this stuff is needed.
