Audew Jump Starter starts dead V8 with ease!

It appears as though they no longer make the specific model of the jump starter I showed in the video. However this is their equivalent model here:
Audew Jump Starter, 1500A Peak 18000mAh Portable Jump Starter (Up to 8L Gas or 6.5L Diesel Engine), 12V Auto Battery Booster with Quick Charge, Built-in LED Light www.amazon.com...
Note: The truck was in the sun for awhile so the 45ish degreevtemperature in the video is inaccurate. I checked on my phone and the temperature outside was 35 degrees Fahrenheit.
