I'm looking at getting portable jump starter to carry in my pickup,it will be available when the winter comes again.
i was just looking some Jump Starte on amazon,i find YUNSHANGAUTO Dual Mode Micro Car Starter 600A Peak Portable Car Jump Starter 12000mAh Power Bank(Up to 6.5L Gas or 5.0L Diesel Engine) Emergency Auto Battery Pack Booster Charger with LED Light. price：$89.9
Has anyone ever used one of those portable jump starter :Start your car from cigarette lighter socket inside the car and Jump start your car outside.
I'm wondering What is the most important factor to choose one Jump Starter,Whether it is worth buying at this price.
