Jump Starter Capacity question...
 

I dont know much about cars but I need to buy a self Jump Starter just in case. What is my Jump Starter Capacity and Gasoline Capacity.

4 Cylinders < 2000cc 7800MAH. I have no clue what I just wrote but that is one line of the checklist.

P.S. I own a 2017 370z A7 Touring Model

Northern Tool: Noco Genius BoostSport Compact Lithium-Ion Jump Starter — 400 Amps, Model# GB20

Worked perfect when I needed it, and, it is id10t proof! Sign up for their email promotions and you will receive discounts. I saved $20 on a $100 purchase, so essentially whatever I bought to get to the $100 was free.

It's difficult to pick a jump starter going by the advertised specs. Lots of variables and it seem that every manufacturer uses different test procedures.

Your checklist specs above mean it was designed for a 4-cylinder engine of less than 2.0 liters. 7800MAH is probably supposed to be 7800mAh (one measure of how much current a source can put out). The specs you listed are very anemic if you want to jump start a 3700cc engine in cold weather (battery output declines and engine is harder to crank at colder temps - double whammy). The one that REVRAY linked to looks like it is more up to the task. And his experience confirms it.
