Price and quality is amazing. Size and battery life is very good. Works perfect!
Michael S. –
I’m surprised on how great this works! Comes in a nice case to keep everything together, holds a charge for months and works every time. Here are things I have tried it on l: Toyota Prius, ram 1500 diesel, zero turn, 60hp tractor, generator. I recommend having this in your trunk just in case.
I buy things –
10/10 if allowed but 5/5 will do. This product is a life saver. One day I woke up with a a dead battery. I ordered this product in hopes to rejuvenate my existing battery and to avoid purchasing a new one. It works like a charm!
– Arrived with 100% battery simon delivery you can immediately service your vehicle
– Allows 30w input charging (Supercharger status)
– Lightweight and compatible for all vehicles
– Price is unmatched
– Includes additional usb ports for other device charging (Laptop, cellphone)
– Upon my first jump, my car battery was completely dead. The starter arrived with a full juice of battery, on the initial jump, my car used a total of THREE% leaving me with 97% of additional juice.
Please note: Do not jump and immediately remove the starter. Your vehicle will require 15-30 seconds of additional charging to power peripheral components (lights, radio, power steering). ai made this mistake and realize my power steering wasn’t operating as expected)

A reliable and user-friendly tool that packs serious power into a surprisingly compact design. Whether you’re dealing with a dead battery in a large SUV or a standard sedan, this jump starter delivers enough juice to handle engines up to 10.0L gas—impressive for its size. It’s intuitive to use, even for those who aren’t mechanically inclined, with clear indicators and a straightforward setup that makes emergency starts less stressful. Its portability means you can stash it easily in your glove box or trunk without sacrificing space.

**Lithium Automotive Jump Starter – A Must-Have for Every Vehicle!**
I recently picked up this lithium automotive jump starter, and I’m thoroughly impressed with its performance and value. Whether you’re looking for a compact solution for emergency situations or a reliable tool to keep in your vehicle, this jump starter ticks all the boxes.
**Great Value & Compact Size:**
For the price, this jump starter offers incredible value. It’s much smaller and lighter than I expected, making it easy to store in my vehicle without taking up too much space. Despite its compact size, it packs a serious punch when it comes to jump-starting power. I’ve used it several times on both my diesel truck and my 30hp tractor, and it has worked flawlessly each time.
**Powerful Enough for Diesel & Larger Engines:**
I was initially skeptical about using a small jump starter on my diesel truck, but this one has proven to be more than up to the task. It easily started my truck even after it had been sitting idle for a few days in cold weather. I’ve also used it on my tractor, and it worked just as well—no problems with starting the engine, even on larger machinery like my 30hp tractor. This lithium jump starter is powerful enough for both cars and heavy-duty equipment, which is a huge bonus.
**Easy to Use:**
The jump starter is incredibly user-friendly. Simply connect the clamps to the battery, press the power button, and you’re good to go. The included instructions are clear, and the process takes no more than a few minutes. It’s so simple that anyone, regardless of technical knowledge, can use it in an emergency.
**Reliable & Safe:**
I love the peace of mind that comes with having this jump starter in my vehicle. It’s designed with built-in safety features, such as reverse polarity protection and overcharge protection, which give me confidence when using it. I’ve never had any issues with it, and it’s always delivered exactly what I needed.
**Portable & Convenient:**
What really sets this jump starter apart is its portability. I keep it in my truck and my tractor, and it’s so easy to grab and go when needed. It’s also incredibly convenient for traveling, camping, or working on the farm, where you don’t always have access to a traditional power source or jumper cables.
**Conclusion:**
If you’re looking for a reliable, high-quality jump starter that doesn’t take up a lot of space, this lithium model is an excellent choice. It’s powerful enough for both personal vehicles and larger machines like diesel trucks and tractors, making it a versatile and indispensable tool to have in every vehicle. Whether you’re a farmer, off-roading enthusiast, or just someone who wants to be prepared, this jump starter is a must-have! Great value, easy to use, and highly effective—highly recommend!

Works well and as described but does lose a good 20-30% charge on jumping a standard auto 6cyl., (no reference on multiple attempts as test vehicle started easily on first try despite being at near 10% charged) but still an excellent value when was on discount, a potential disaster saving item when no one is available to jump start, and may actually buy a second unit though possibly with increased capacity.
