⭐⭐⭐⭐⭐  Michael R.

✔️ Verified Buyer

I’ve been using the Jump Starter for a bit now and it’s been really solid. It works great and it’s one of those things that’s just good to have in a pinch. Knowing it’s in the vehicle gives me some peace of mind if a battery ever dies. The emergency light on it is actually awesome too  and really useful if you’re need extra light while working on something. The USB ports make it easy to charge a phone or other small devices when needed.

⭐⭐⭐⭐⭐  Jones H.

✔️ Verified Buyer

I highly recommend purchasing this jumper. It has multiple charging ports, two USB-A ports and one USB-C port which makes it easy to charge multiple devices when needed. At the top end of the jumper is a bright LED light with three different lighting modes. The simple LED display on the front side of the jumper clearly indicates the percentage of charge.

✔️ Verified Buyer

Cold weather can do strange and unexpected things to car batteries. A short time after purchase, I was able to help a couple stranded in a parking lot because their battery died (after tailgating a hockey game in the snow.) It was easy to connect to their SUV, which started up immediately. It is compact enough to keep in the trunk and has held a charge for a couple months.

⭐⭐⭐⭐⭐  Grapes R.

✔️ Verified Buyer

This jump starter was an absoulte life saver. I had one previous to this one, but it was only 1200A. The one that I previously had was enough to start my car, however, after I left my car sitting for a week in VERY cold weather, my jump starter was unable to start my car. This jump starter was the answer. 

⭐⭐⭐⭐⭐  Brooks H.

✔️ Verified Buyer

Overall, this is a great item to have on hand for peace of mind. It’s easy to use, powerful, and much more convenient than relying on jumper cables. The clamps are sturdy and easy to connect, even if you’re not super familiar with car batteries. I’d definitely recommend it for anyone who wants a reliable jump starter to keep in their car.

⭐⭐⭐⭐⭐  Morgan R.

✔️ Verified Buyer

We keep this jump starter in our vehicle and it has already come in handy more than once. It’s compact enough to store easily but powerful enough to jump a dead battery quickly without needing another car. I like that it works for both gas vehicles and larger diesel engines, which makes it versatile for our household.
