Review: Came in Clutch to Jumpstart My 2004 Lexus ES330 - I ordered this AstroAI S8 battery a little over a year ago. Its primary purpose would be to have an option for jumpstarting the battery in my 2004 Lexus ES330, and its secondary purpose would be to have an option for charging my phone or other portable electronic devices. At that time in late 2024, I was transitioning to a new vehicle but was keeping the 2004 Lexus as a backup. Because I wouldn't be driving the 2004 Lexus much, I felt the need to have an external battery option for jumpstarting the car battery. I haven't had to use this until now, but man am I glad I had this. After fully charging it when I received it, it had been sitting in the vehicle unused for the past 12+ months. I don't recall if I ever recharged it during the past 12 months. Regardless though, it seemed to hold a charge pretty well. I had to use it this past weekend and it appeared fully charged. The first attempt at starting the car was unsuccessful, and it did use up ~25% of the battery. I was worried that the issue wasn't a dead battery but something more significant. However, after exploring other possibilities, I decided to give the jumpstart another shot. This time it worked perfectly and the engine started up! This was really easy to use and it came in clutch. Nothing more I could ask for. Just be aware that each attempt at jumpstarting may use about 25% of the charge, so realistically you have 4 attempts at most before this external battery is drained.
Review: Very handy and reliable jump starter - This AstroAI car battery jump starter works great and is easy to use. It’s compact, well made, and gives peace of mind in emergency situations. It starts the car quickly and holds a good charge. Overall, a very useful tool to keep in the vehicle and great value for the price.
