chrigel.fahrni9 years ago+3+30I would also like to use this device to power my cool box (12V plug). Is this possible with the GB40? Where could I order the appropriate cable?Show in original language (German)L_00_T9 years ago • purchased this product-10-1purchased this product Helpful answerPossibly on the Genius homepage. There are also many reviews on YouTube. I bought the "Swaytronic All in One Jump Starter 18'000 mAh" -> it has more connection options, but is not as robust as the GB40.Show in original language (German)Comment
