I got one of those smaller powerpacks that can help jump a smaller car, as well as having USB charging ports and more. Has worked twice on my mother-in-law's car. Got another for Karen for her car, too.
Here's one example, https://www.amazon.com/gp/product/B077HQ3RMC/ref=ox_sc_act_title_1?smid=AY5XLL1NQPR7O
Another ~$20 off with coupon code: KEIA972K
In any case, hope you weren't TOO cold, and good luck tomorrow.....
