Hey guys. I'm in the market for a new jumper pack. I'm wondering if I should buy a 12v truck pac from clore automotive or buy one of those pocket sized packs, and if so, which one?
How's the Noco GB70?


Thank you for that link. I see that the JNC660 has a strap that goes across both sides of the clamp essentially making them both "hot" where as the JNC770R does not. Does this make a big difference? Is the weight difference and digital readout worth the extra money? I can give or take the light and USB (though a nice feature). But do the clamps make or break it?
I think you're right about the faster charging. The 770R has a 3 amp internal charger listed on Clore's website, the 660 doesn't have a spec listed. You're right also about the reverse polarity protection. I did a somewhat in depth thread comparing the two and I missed those two details, so thank you.I looked at both and bought the 770, so I can't really compare the two. I do know the leads are longer on the 770, which is really nice. It has the light and 2 USB ports. I've never used the USB, but I have used the light and it's very bright.
The 770 also has an on off switch that I think the 660 doesn't have - which is useful - you can turn the leads on after you get them connected, then turn them off before you disconnect - no sparks - no explosions.
I think it also had reverse polarity protection, which is good when I loan it to people. It has digital readout, which doesn't really give you much.
If you are pressed for cash, the 660 will work fine. If the $25 extra isn't a burden, the 770 gives you some nice upgrades.
Edit: One additional thing that they may have upgraded on the 770 is the charger. It seems to recharge when you plug it in extremely fast - like both time I've done it 15 minutes or less.

I've used it way more times for other people. My vehicles get up kept, but the odd time something is left on they work well. I do a lie of work for other people so having one on hand or for neighbors is beneficial. But I agree, be proactive with vehicle maintenanceI found that keep up on battery replacement and load testing avoids the need most of the time for having a charger or booster Pac. I see people spending money on these things only to come to the conclusion of battery replacement. Good to have in that odd time of leaving your lights on and running down the battery. I have a portable charger with a engine booster mode. For my daughter I have thought about a small lithium Pac.
It comes with cords, but they're separate.How does the 770 charge? Is there an AC cord on it?
My 78 325I died the other day on me and my neighbor brought over his XP10 and gave me a jump. He said he hasn't re-charged it in months and I was the 10 tenth car he has jumped since last charging it.
It is small, very small. Is this unit really that good?
