AVAPOW 4000A Peak Car Jump Starter, 27800mAh Battery Jump Starter, Portable Battery Booster, 12V Jump Box with LED Light, USB QC 3.0, Yellow

I bought this product for two reasons. Its performance is undeniable! Real easy to use and both my vehicles started up without hesitation and stalling. I used it for my old truck sitting in my driveway for about two years. Didn’t fully have enough power to start up or turnover. This product came in handy. My second reason was for my wife. I leave out for work before her and on a few occasions she left the inside light on and in the morning needed a jump and I’d already left out for work. The jump starter came in handy again. Now I have two. One in each vehicle

Works as advertised. My car batt tends to die when temps below freeze. Day starter arrived it was in 20s. Batt had died. The starter arrivd fully charged (glad for that). Connected red and black cables. Turnd ignitition and car started right up - NO DELAY!! This jump starter works!
