So what's the best bet? Genius GB40 1000 amp for around $100 or the Genius GB70 2000 amp at around $200. For anything from a 4 clinder SUV to 8 cylinder truck, possibly a sub-compact tractor (someday), garden tractor etc.? 

I paid $174.95 for my GB70 shipped on EBAY. IMO it's one of the situation's where bigger is better.

Just got my Genius Boost/GB40 jump starter. JoAnn ordered it for me through her Amazon Prime. Haven't taken it out of box but am amazed at how small it is.

That's exactly what I have - also bought from Amazon (sometimes I think I should just endorse my check over to Amazon and be done with it  :)  ).  With the various vehicles and equipment I have around here, it's not uncommon to find a dead battery when I need to start one.  This thing works fine on everything so far.  MUCH easier than messing with another vehicle, jumper cables, etc, especially in the cold.  I keep it in the old Jeep because at times the dogs and I go to some pretty remote places in that thing during grouse season where a dead battery would be a major problem - hasn't happened yet, but I am confident the jump starter will work if needed. 

 

Obviously, you have to keep it charged.  Dunno know how long it will hold a charge - I just charge it every couple of weeks to make sure.

I have two that I bought to start the big diesels on my boat. I only carried one at a time and it would spin those big hunks of iron like  a toy top. Unfortunately, they are in PA and I am in FL. But you could get them through marine repair shop that works on the big boys.

I was surprised that it uses a USB cable to charge and not any common electric plug. Also surprised they didn't include the USB charge unit to plug in the wall. I used my iPhone charger in wall outlet and it was fully charged in a few hours. They did included the cigarette lighter type Charge unit for USB. Did you find the charging instructions a little vague? 

 

Regardless, it's incredibly well designed and attractive, sturdy and compact. That includes the excellent packaging which I appreciate given my commercial art career. I'll have to wait til I can't start something to test it out I guess.

I may have waited too long but Im ordering the NOCO GB40 this morning from Amazon. Unless someone has a better suggestion in the $100 range. might get the hard case for $15 too. Looks like it only comes with a soft bag??

The dangerous cold is about to hit us

Finally got to test my Noco Genius GB40 this week. My battery went dead in my truck. It had been cranking poorly this winter and gave up the ghost with low digit and minus temps in morning. I hooked up the little jump starter in 5° temps and it cranked the truck like I had a new battery, started the truck, no problem. Im sure it would have started the truck in even colder/minus temps. I'm a big fan now. Went and got a new battery etc. 

 

Mine came with a soft bag bag which is fine for me, holds the Boost, cables, manual and charger cable just fine. But if it's gonna get bounced around in a truck bed etc, a hard case would be a good idea.

Wouldn’t it be better to spend the money on a battery load tester and replace a bad battery before hand

Ended up buying the Noco GB40 this past spring.  Well.......had to test it last night.  F150 had a weak battery, felt like just not enough to turn over the motor.  I was excited to try the little booster out - did just short of nothing to help.  I tried 3 or 4 times, and even tried the bypass.  Still not enough to fire up the v6 motor.  I ended up hooking up the 50 amp 120 volt booster to make a go.  But lost confidence in this unit.  I have reached out to Noco with my situation and hoping they quickly address.

I used my new GB40 a couple days ago on my sons car. It was as dead as could be. Didn't turn over a bit. Just a couple of clicks.

Hooked up the battery pack, turned it on and waited 10 seconds. Turned right over, chugged twice and fired right up. I was a sceptic but was very impressed. Im sold on until Im not.

Cool little units. I is freaky that something so small can bring a big truck or vehicle back to life. I didn't wait 10 seconds after turning it on when I jump started my truck. Is that recommended in manual?
