I have a Gooloo GP4000 and it is the bomb. I've jump started a bunch of stuff and haven't had to recharge it yet. Mine came with a hard case. It was $85 on Amazon with the $14 coupon.

I purchased a carry case for my GT 4000 today. Easier storage in trunk. Made by GOOLOO

Here I thought for whatever reason that the preheat was for glow plugs/intake heaters haha

So, did Gooloo warranty out the one with the pre-heat problem?

Please give us a logical demonstration of all ports on end of unit. I have not seen a good demonstration yet. Such as how can I power up my laptop with unit etc.

This is not a real world. In a real world situation the gooloo would be out in the cold probability in the car and would be trying to preheat in the cold of the winter day not a warm summer day
