Review on Jump Start Your Vehicle With AUTOGEN 3000A Car Battery Jump Starter For Gas And Diesel Engines Up To 10.0L by James Morrow

This jump starter is awesome. It is so far the largest and most powerful jump starter I have ever owned.I just purchased about a week ago and yesterday I was able to test it by starting an 8.6 liter six-cylinder diesel truck with a dead battery. Nothing happened on the first try. After consulting AUTOGEN customer service, they advised to press the boost button to start a dead battery which i forgot. Then I try it again. It spun the engine just in seconds, as if it had a brand-new battery. I should say it was much better than I ever expected.Pros:1. Really safe: I tested it by connecting the clamps reversely. It alerted, but nothing bad happened. No sparks at all.2. Powerful: start my 8.6-liter diesel vehicle right away;3. Convenient: Used the battery for 12V vacuum cleaner and air compressor directly, no extra cable required;4. Bright flashlight: hold the power button for 3 seconds to turn on the light. Pretty smart design. The flash flight is really bright.5. Quick charge USB ports: I can see it charges my new iPhone much faster than a regular charger.Cons:1. It does not support 24V vehicles; I wish AUTOGEN could have a 24V model soon!2. It does not have a port to charge laptops as other models. It would be nice to have, but not necessary for this professional model.If you like a really powerful jump starter with a large battery to last long time, this is definitely the one! You can just tell by feeling the weight on your hand. To be honest, I would say this price for what it is is a bargain!
