YaberAuto Jumpstarter and air compressor combo Unboxing and testing. Blackfriday deal!

[@Crazypostman]

Didn't get to do as much actual testing with this one as I wanted due to that friend emergency I had during filming. And then I had to head to my dad's birthday party. So I will add to this pinned comment if any negative things happen with this product over the next few weeks my dad has it.

Wow that was draining fast.

I am concerned about the short inflation cord. It seems like you've got to ensure the tire valve has to end up at or near the 6 o'clock position. loved the asmr of the tape removal.

@@bikeny I didn't think about that at the time, but now that you mention it, it is rather short. with the inflation connection in the center of the bottom, You would have to hold the machine if the valve was at the top of the tire probably. Good catch!

Hey Crazy postman. This is not up to your usual standard. I think you should have first tried to start the car engine with its own battery. If this works, then the booster is unnecessary. Then you should have checked the car battery voltage. Boosters generally only work if the battery is above about 9V. You did not make this clear in your review. If the battery voltage is below a certain value, then the booster will see it as a short circuit and will lock out. So they will only work with a partially depleted battery. Contrary to many comments on KZbin they will not work with a "flat" battery. Thirdly when you disconnect the jump leads, you should turn both engines off first, and you should remove the negative lead first. Just saying😊

@zinniasequoia yes my testing got cut considerably short due to late shipping and another thing that came up. This is more of a showcase, instead of a review now I guess. The battery was not completely dead just not enough to start the truck. This jump starter does have a "boost" button that will activate it even with 0 volts on the car battery.
