Review on GRAYBULL Adapter Connect Battery Product by Roberto Gonzalez
Disappointing performance in Automotive Adapter
As a result of my tests, I determined that this adapter connect battery product was inadequate for automotive use. The device failed to provide the necessary power to jump start my car leaving me stranded. The compact size and portability were the ONLY pros, but unfortunately this was not enough to compensate for its poor performance .The cons heavily outweighed the pros, making it not worth the investment..
- Easy and quick installation process
- May require professional installation for some users.
