With that being said, there has been times where I'm by myself, on flat ground, trying to push my heavy ass adventure bike to a running start, while wearing full protective gear in 90+ degree weather, where I would've killed for this Jumpstarter.
This is most likely for the jumper cables.
The USB OUT port is completely different; it outputs power at 5V.
So if you're using only the USB out port, the yield from the battery will be:
11.1V ÷ 5V = 2.22
2.22 * 2150mAh = 4,773 mAh @ 5V." -Gas Ginser reviewer

This product probably compares to the Gooloo 1200amp products which are priced similarly at ~$80.
In general all these companies inflate specs quite a bit so a jump starter rated at 6L not being able to jump a 5.7L V8 even in ideal conditions isn't a huge surprise unfortunately.
I guess I'm just saying both this NOCO and the gooloos are both cheap china made battery packs currently priced around $75 and the real slick deal here is the 4000a one you got for $80.
Do me a favor next time you see the Gooloo 4000a for $80 post it to slickdeals so it will set off the new alert I made
Just checked on it because of this post, it's been a year since I charged it last, and it's still got 2 bars.
All that said, NOCO customer service is some else to be desired. 4 rounds of cut and paste responses that not quite address my issue w/ the battery tender before a human typed out a response.
I've used this a handful of times from small cars to trucks to full size SUVs. Of particular pain is the 2007 Q7 we have which uses a ridiculous H9 AGM battery between 850-950CCA...but it has worked for this vehicle without fail as well.
We don't see 100 often here, but we do get -30 and sub-zero temperatures and it's been fine kept in the vehicle with minimal discharge. I'd echo what others have said and maybe an average discharge of 1 bar every 1-3 months. But in the warmer months, I have not seen much discharge at all so far.
In any case...if your battery is particularly low or "dead", you will need to utilize the manual override in order to jumpstart the vehicle. See below.
Manual Override Details:
NOCO Genius Boosts are designed to jump start 12-volt lead-acid batteries down to 2-volts. If your battery is below 2-volts, the Boost LED will be "Off". This is an indication that Boost can not detect a battery. If you need to jump start a battery below 2-volts there is a Manual Override feature, which allows you to force "On" the jump start function.
CAUTION. USE THIS MODE WITH EXTREME CARE. THIS MODE IS FOR 12-VOLT LEAD-ACID BATTERIES ONLY. BOTH THE SPARK PROOF AND REVERSE POLARITY PROTECTION FEATURES ARE DISABLED. PAY VERY CLOSE ATTENTION TO THE POLARITY OF THE BATTERY BEFORE USING THIS MODE. DO NOT ALLOW THE POSITIVE AND NEGATIVE BATTERY CLAMPS TO TOUCH OR CONNECT TO EACH OTHER AS THE PRODUCT WILL GENERATE SPARKS. THIS MODE USES VERY HIGH CURRENT (FROM 400-4000 AMPS) THAT CAN CAUSE SPARKS AND HIGH HEAT IF NOT USED PROPERLY. IF YOU ARE UNSURE ABOUT USING THIS MODE, DO NOT ATTEMPT AND SEEK PROFESSIONAL HELP.
I was replacing cheap amazon lithium power packs yearly before this one.
