This jump starter is an absolute lifesaver! Compact yet powerful, it quickly brought my car battery back to life without any hassle. The build quality feels solid, and the additional features like USB charging and a flashlight make it even more useful. It’s definitely worth the investment—having this in your car gives peace of mind in case of emergencies. Highly recommended for every driver!

Impressive and started my dead jeep instantly. Small, light and easier and much more convenient than a traditional jump. Worth having when you need it.

The day it arrived I charged it with my MacBook Pro USB-c charger for less than an hour until fully charged. An hour later my car would not start. I hooked ip up (VERY easy and SAFE), let it charge for 2-3 min, and the car started as soon as I pushed the start button. Charger showed it had dropped from 5 to 3 bars, which I assume means it is good for two starts before needing a recharge, but it is a tiny little device (as compared to long jumper cables and a 12 volt car battery), and since most cars today include USB outlets I suspect it can be charged while driving. It takes little room to keep in trunk and could be a lifesaver--for me or just helping another driver. HIGHLY RECOMMEND!

It appears to be a good sturdy unit. But the proof will be if it jumps my bike. I do see that the cables are a bit short, ok if working on a car, but motorcycle batteries are a different breed. So, for now I give it a 4 based on these comments.

I bought two of these for gifts and they give us added security when we’re on the road. We love the size, the ease of use and the reliability of the charger. All you need to do is charge it at home and then keep it in your car for emergencies.

At first I was ready to return it because it didn't work for me. Truth is my battery was bad a lnd not just dead. I bought a new battery which was also completely dead when I brought it home, I decided to try the Jumper again. The trick is to leave it on for a couple minutes even hit the boost button. Started it right up. It's great. Very light weight and compact. Most have!

The battery charger came quickly and was well packaged. I had occasion to use it on a dead battery shortly after receiving my order and it was easy to use and worked great. I particularly like that it has a battery pack which means that you don’t need to have access to an electrical outlet in order to use the charger. This makes the charger portable and usable wherever you encounter a battery problem. It’s compact and easy to use.

Normally when you look for a portable battery pack they cost hundreds and they’re big and bulky and harder to store. This one is compact, easy to use, perfect for emergencies. I like the function that you can charge the battery pack from your running car! If no one has jumper cables and it was low on battery you will always have an option. The battery runs low quickly but that’s given it’s a lot smaller and has a lot of power. The flashlight is bright with multiple sos settings. There are dual ports to charge devices, it is simple but amazing. This is the perfect portable battery pack for me and my situation.

I am beyond impressed with this jump starter! It’s compact, easy to use, and has been a lifesaver on multiple occasions. The first time I used it, my car battery was completely dead, and this device started my vehicle in seconds—no need to wait for roadside assistance or ask strangers for help. The build quality feels durable, and I love that it also doubles as a portable charger for my phone and other devices. The instructions were clear, and the included safety features gave me peace of mind while using it. Even in colder weather, it performed reliably, though I did notice it worked best when fully charged. Overall, this is an essential tool for any driver, and I highly recommend it to anyone looking for a reliable, portable jump starter. Five stars without a doubt!"

Producto de excelente calidad, cumple muy bien su función, la batería de mi auto estaba totalmente muerta y con el Boost mode pude encenderla, te saca del apuro si lo que buscas es encender el motor, pero no carga la batería de tu auto, para ello tendrías ya que manejarlo y que se recargue el nivel
