IDEAPLAY J10 Jump Starter is a must have for all of your vehicles! I’ve been having intermittent issues with my car needing jumped. It happens infrequently and the dealer can not tell me why it happens. Battery is good and no issue with the alternator. A jump solves the issue. Trying to find someone to jump you or when your car is parked in a spot that makes it difficult to jump can be an issue. I went out to start the car the other morning and it would not turn over. I connected the battery pack with the included cables and let it charge. The light flashes red and green. You ear a few clicks which it is charging the battery and the light becomes solid green. It turned over on the first try! So worth having especially when in a pinch. It can also be used as a flash light/ Emergecy flashing light or charger! Highly recommend this small monetary investment for all your cars!This item arrived very quickly and I was impressed on how well it functioned! My car did not want to turn on after work but luckily I had this jump starter in my car and it turned the car on right away! I would definitely recommend purchasing this as it got me home after a long day at work! It even comes with a carrying case, which I am a big fan of!This thing is a life Saver. Got here just in time. My truck battery wad dead when I remembered I had my booster in my glove compartment and it's so much easier than carrying them long big jumper cables . Highly recommend.Starts high compression race car no problem w completely dead battery! After 2-3 jump starts still over 90 percent battery! Charges fast also!Easy to use. My elderly neighbor recommended this product. I have since purchased several for gifts. Great to keep for charging devices, charging a car battery etc. definitely recommend.Truck fired right up.Tried several and this was by far the bestVery
