I could. I’ll probably discover i bought it 3 years, because time flies, but I’ll give it a shot
I have one in the wife and daughter’s car for emergencies. They’re not the most powerful units but worked in a pinch when someone leaves the lights on while shopping etc. There are more powerful ones out there but so far the unit has retained its charge.
Fortunately, never need it to jump a battery. Just trying to recharge the darn thing. Plus, we now have 2 older vehicles on the road, so it's only a matter of time before "dad's road service" gets a call. I mean, my newest driver told me, "I don't have to check the oil. The teacher told us the light will come on if it needs oil?" I don't know who's failed more, the teacher or me
But fear not friends of GJ, she'll be changing her oil if I have anything to say about it!For me, powerful is not very important. I have 4 and 6 cylinder cars. Easy to jump. The key is long life and safety. Won't explode under CA sun. I have never needed one in the past three years. So longevity without usage is also important
if you look at what's a in a jump pack, it's "just" a high C discharge Li-ion and some wires. not much to it. they are good for helping out a "dead" battery (cluster lights up but goes click), but not a stone dead battery (no key activity).
it's a 12V battery inside. hook it up to a 12V lightbulb. remember, it's a small battery. enough juice to assist a too-dead-to-start SLA battery once, maybe twice, before recharging.
Li-Ion battery is not maintenance free. If you let the voltage drop too low, the charger simply refuses to charge it for fear of overheating and causing fire. It's the same with the batteries of your phone, computer, and power tools. I would charge the battery at least every 3 months. Brands may not be as relevant as not letting the voltage drop too low.
same here
The lithium packs suffer from the off shore copy counterfeit problem. So be careful where and what you buy.All of these dead Lithium Ion jump pack threads makes me want to either get another JNC 770r or try one of those super capacitor jump packs. Have saved a lot of people with my JNC including wife, parents, myself, random dudes, but no damsels in distress yet
The thing about lithium ion batteries is you can't let them go completely dead. The problem may not be a quality issue with the box, it may just be the nature of lithium ion batteries.
No teenagers in the house I guess?
None that can't recognize how old their battery is.
Never left their lights on, or drained a good battery by accident? Mine haven't yet either, but **** happens. Heck, my boss sat on a conference call last week at the turnpike plaza, with the car off. Probably had his PC and something else running, because when the call was over, his car wouldn't start. He used a battery pack to start it. Could be the batter was old as well perhaps. The week before, one of my team had an alternator go bad on him, but 2 weeks prior, it was the battery and he jumped started that. Yes, the alternator was obviously bad then. Not sure if he missed that, or if he had a mechanic do it. Either way, at least he had a way to jump it the first go around.

The AGM or wet cell jump packs fail just as often, with huge weight and size disadvantages.
The wet cell batteries are relatively low cost to service. This one has $40.
The SUPER Capacitor might not be ready for prime time ???????
I inadvertently drained the battery for a no-start situation because the dumb Subie "auto" head lights remained on with the key in acc. listening to tunes while the LOML shopped. But the Costco lithium jump pak saved the day
A lot of small M/C/ATV batteries have 400 CCA which will start most cars/trucks. I would buy a decent small battery and a couple cables/clamps than buy those all in one jump packs. Most people have a small batt charger to charge them up. Most of those "jump packs" use the cheapest batteries they can get away with to last the 1 or 2 year warranty.
