    When I ordered the jump starter, I did’nt have any battery problems with any of my vehicles. But a couple of days before it was delivered, the battery in my 1976 F-150 went dead. This presented an excellent opportunity to try the new jump starter out. When it arrived it had a 78% charge. The instructions say to charge it for three hours when you first receive it. After the first hour on the charger it still had 78% and had me worried that it was defective. But after that first hour it started adding percentage and was fully charged before three hours were up. My pick-up has a 390 cubic inch V-8 and is sometimes hard to start when cold; but I hooked up the jump starter, turned the key and it started right up, using only 7% of the charge in the jump starter. The jump starter seems to be of very good quality, has a very nice case to keep it in at a very good price. So far I am very happy with my purchase.

    So far perfect. Great starts, easy operation, multi-functional and a super price . Can’t go wrong here. It comes with a very attractive hard cover case that is compact and easily stores in your vehicle until needed. Very pleased with the quality and design.

    I’ve used this twice to start my farm truck, whose battery was absolutely dead. Truck hadn’t been driven for 8 or 9 months. Horn wouldn’t blow, no lights or window power. Attached this jumper and in about 1 1/2 minutes the truck started. Since the battery wasn’t charged, had to jump it the next day and again it started in about one minute. I was amazed at its performance and highly recommend the product. It was 77% charged when I opened the box and after two jumps the remaining charge was 64%. Comes with a great, hard shell, zipper storage container. Very easy to setup and use by anyone.

    The battery in my car died. Completely died. It would not crank at all. I wasn’t able to go get a replacement battery right away, but I was able to order this portable jump starter. I was able to start the car every morning and every afternoon for several days using this portable jump starter. I never had to wonder if it was going to work, it just worked every time. I’m still amazed that something so small can jumpstart a car. I am going to get one of these for all of my vehicles just so I can have it on hand in case I need it. I have no Reservations about recommending this product for anyone who wants the convenience and the peace of mind of a portable jumpstart.

    Jump Starter works great. I ended up purchasing two. Love that it comes with a hard sturdy carrying case. Easy to use.

    I bought this jump starter in October 2024 after a frustrating experience where my car battery died while I was grocery shopping. I had accidentally left the headlights on, and by the time I got back — around 9 p.m. my car wouldn’t start, and I had no one to call for help. That night made me realize how important it is to be self-reliant in such moments.

    Since I’ve been through that more than once, and after paying way too much to roadside services for a simple jumpstart (literally takes 2 minutes with the right tool!), I decided to invest in one of my own. I came across this model after seeing a mechanic use something similar and I am so glad I did.

    This jump starter has already saved me twice. It’s compact, easy to use, charges fast, and does the job flawlessly. The instructions are clear, and the fact that I can now handle a dead battery all by myself feels so empowering. As a woman who often drives alone, this tool gives me peace of mind and independence.

    I’d strongly recommend this to anyone — especially women or folks who don’t want to rely on someone else in emergencies. Keep it in your car, you never know when you’ll need it. Truly a must-have for every vehicle!
