Car Jump Starter 3000A, Jump Starter Battery Pack for Up to 9.0L Gas and 7.0L Diesel Engines, 12V Portable Jump Box with LED Light

I bought this device shortly after I found myself stranded on the driveway of my cabin in the boondocks with a dead battery. I had to call AAA, and wait over an hour plus to get help. The driver had a portable charger. He connected to the battery terminals and, within 30 seconds, my truck was running again. Made it to the auto-part store, got a new battery...THE END. That same afternoon, after that morning's adventure and freak-out, I decided to get a portable jumper on Amazon for "next time". I found this SHARMEAL model for 29 bucks...SOLD! Fast forward to today. I am in a business parking lot minding my own business when this lady is walking around asking people for help because her battery is dead. She parked nose in, in a double row--where access was impossible with cables unless her car was pushed out to the middle of the parking lot. ME TO THE RESCUE! Wondering if this power jump starter would do the job at all. At first she looked at me suspiciously, asking herself how this weirdo holding the black and orange little case would be able to help her at all. I explained. Turned it on, connected it to her battery, let it charge for a few seconds, asked her to give it a go and....SURE ENOUGH, Her car started right away! She couldn't believe it. She took a photo of it with her phone, and asked where I got it. I told her. I believe you'll get a new customer. You are welcome, Sharmeal! Awesome purchase. It is ironic that I didn't get to use it on my truck the first time but...I am very pleased to know it does the job. My only observation about this product is this: It does not include a 110 v. wall adapter for the USB cable. Otherwise, perfect. It includes a built in little compass (okay!) and a flashlight. I am glad I bought it.

I've used this a couple times now, and I'm really impressed on how long the battery holds up. Drove my 1999 Suburban with a dead alternator and dead battery about 1/2mi without cutting out, and only stopped because that's where we were parking it waiting for parts. Said it had about 56% left in it, that's pretty impressive. We started it up a few times to drive it up and down the tow dolly to move it around, and I've even used it to keep a battery on a E90 BMW charged while doing an electronic coolant bleed procedure.Charging capability:Takes a while to charge, but I guess it's got to charge up a large battery. the USB Type-C charging is useful, since a lot of my rechargables now charge of that too. As far as charging other stuff, it works ok. 2A isn't super fast by modern standards, but my iPhone doesn't complain, my work laptop does complain but it still charges, and my work flashlights only draw up to 1A so they don't care. Ease of use:You plug in the cables to the box, press the power button, and start the vehicle. Works pretty well. The cables are different lengths which bothers me a bit, but it's not so bad. The case it comes in holds everything well, and feels sturdy enough to throw in the back of your car or in a tool box at work (like I do). The flashlight modes are kinda gimmicky, but I guess they work and it's not like they impede operation. SOS mode works, the lights are fairly bright, but the box is pretty hard to comfortably hold for long periods. The compass on mine is sticky, and takes a while to face north. But, it's a jump box not a flashlight boy scout multi-tool, and the jump box portion is great.

Super easy to use. Came already 99% charged. But after use I still recharged to 100% for next use, using the charging cable. Cables work perfectly. I do wish they were just a bit longer. But no problem. I like the LED lighting on it and an emergency light that you can put on flash mode if needed. Very light and compact for easy storage. Used to jump start a 2017 ford fusion. As soon as I attached, without even starting the car, the lights came on. Definitely worth the $30. Probably going to buy one or two more just to have handy in our other vehicles. Highly recommend this!!

This arrived in a timely manner & has worked to jump start my car - have been grateful to have it while dealing with battery issues. The one issue is that it sometimes takes a very long time to recharge - the % doesn’t change for hours at times - for example is at 29% now & has remained at this % after trying to charge for a long time. Is there any trick when it is doing this? It has always eventually started charging & I can’t figure out why it stays at same % for hours at times before charging? Thank you for any ideas.

I waited until I actually needed it before writing this review. My vehicle has an electrical issue that when I leave it sitting for a few days sometimes it drains my battery. So I purchased this a couple of weeks ago knowing I would probably be needing it.Today I went out to start my car and not enough juice to get it to turn it over. Dang it! Well here goes... I hooked it up and she fired right up!Now to be honest, I went with all the positive reviews when I purchased this, but when I received it, I thought it was way too small and light to actually work. I mean it's smaller than a 1/2 carton of cigarettes and probably weighs the same lol. Yet it came 98% charged, I charged it to 100%, stuck it in my glove box and the thing actually worked! And it still has 98% left on the gauge.The ports for the USB outlets and the light are nice extras. So far so good!

I finally unpacked this jumper box and had to jump start my truck.. after connecting the cables my Super Duty started right up.. I would give 10 stars if I could.. I was skeptical at first due to it being so compact.. but impressed with the results.. this is packed nice and fits in my glove box.. I definitely recommend getting one.

Fast shipping overnight. I was skeptical at first, but this Jump start battery product worked well. It is easy to use, and it worked on a Jeep Wrangler 4x4. I followed the instructions and started the Jeep. Of course, I went to Advance Auto for a new battery, and the guy who tested it advised me the Jeep battery was completely dead. I replaced the battery, and I am thankful that I bought this Jump start battery power product, cause it really got me going on my way.
