AUTOONE 4000A Car Jump Starter Battery Jumper Starter Portable for Compact Car Up to 10 0L Gas and

This jump starter is a beast. Fired my car up instantly with no issues at all. Super easy to use, compact enough to keep in the trunk, and the build quality feels solid. The battery holds a charge well, and the extra features like the flashlight and USB ports are really convenient. Comes with a nice storage case too. Definitely worth the money and gives peace of mind knowing it’s there when you need it. Read more

I've been shopping around a long time for a jump starter that works on my cars as well as my 26' bus. I didn't need anything with a million bells and whistles, just something that would work the first time and not have to be charged up every 3rd jump. It's super simple and easy to use. It's built like a tank and works well. The cables are long enough to get comfortably to the battery leads and it's been a good length for my vehicles. Quite honestly I don't really want long leads on it so it's easier to pack and store. I'm glad I bought this one as it does exactly what I need it to do, and it's so portable and small that I can just throw it into the vehicle I need it to be in when I leave. My only complaint would be that some of the plastic clip gets in the way of the tiny battery terminals on my Suburban, but it's side mounted and there's a lot of rubber on them so I don't really hold that against this unit.

I had a different (potentially same as the design is identical) jumper before and this is its replacement. I use my jumper on average 2-5 times a month (helping neighbors and random strangers I may encounter with it) This is absolutely fool proof, easy to use as everything is one way directional and color coded. It charges in a relatively good time, I will admit I don't let it get to "0 bars / lights" but it's more of a set it and forget it kind of thing. If I jump one or 2 cars, I let it recharge within about 3 hours. That being said this ALSO has the great function of being a battery back up as well, while not as portable as some of the more "made for pocket" on a road trip keeping your phone charged these days is a must. I've never had any issues with overheating on the unit itself but the charging blocks CAN heat up. I feel like that's more of a charging block resistance issue than the jumper itself. It does auto turn off as a safety feature once it's fully charged which give me more peace of mind to leave it alone so it can do its thing. Read more

Works just as well as my NOCO which was almost twice the price. I am going to order another. Reason for 4 stars is it is a little slow to recharge. Read more

This jump box is absolutely amazing simple to use small in size great convenience. Purchased it for peace of mind to have extra help and jump starting my 2022 Silverado and my 23 Dodge Ram and it does both if you're on the fence about having something that will work for a V8 truck engine this is the real deal you won't regret it !!!

This jump starter is terrific. When my battery died recently, I tried calling AAA. Somehow there was a mix up and they never showed. I went to Amazon and found this item, purchased it and it was delivered by 7 AM the very next morning. It came 3/4 charged so I attached it to my battery and it instantly started my car. I will now carry this with me wherever I go. Great product, great price. Read more
