17 reviews for UTRAI Jstar 4 Jump Starter with Wireless Charger 2500A Peak 16000mAh (up to 8L Gas, 7.5L Diesel Engine) 12V Car Battery Booster Portable Power Pack
I like everything about it! I can’t believe how well it works. It spun my 4.2 litre over quicker than a new battery. You can also use it to charge your cell phone. It has a digital read out to let you know how much charge is left in the unit. Mine came with around an 85 percent charge on it so I plugged in the usb charging cord and charged it up to 100 percent. Didn’t take long to charge it. I gave it to my wife for Christmas and am going to purchase another one for myself. It’ll get the job done when you need a jump. It’s so awesome for the price! I couldn’t believe how well it works!!

I have an my car with a 4.2l engine and the battery compartment holds a battery that is between 600 to 800 cold cranking amp. My battery is less than 6 months old but in cold weather the battery is just not enough to turn the engine over._Given my old battery booster, which is ten years old, was only a 300amp one that one doesn’t hold a charge for more than a few days. I had a few options to get my SUV running in sever cold weather. In the past I would change out the battery with a warm one or run an extension cord out to the Trailblazer and use my battery charger as a battery booster._ I had heard about the new battery boosters and watched a few video on YouTube about them and decided to purchase this one the UTRAI JStar 4. I am very glad that I did._Recently after sitting over night in below -20 degree weather, with a wind chill near -40 degrees, the engine on my Trailblazer would not turn over. A check of the batteries voltage showed that it was only putting out 9.2 volts due to the cold weather._Grabbed my new UTRAI Jstar 4 and connected it and started the Trailblazer. It started right up as if it had a brand new battery in the middle of summer._I have now had to use the Jstar 4 twice within the 10 days that I have owned it. I am so glad that I bought it. I didn’t like have to mess around outside in the extreme cold just to start my SUV.

The car was not able to start when I needed it to, had no idea what has happened as a new driver myself. Then I search online and ran a quick troubleshooting according to the internet, and came to conclusion that the car might just had a dead battery for some reason. So I ordered this jump starter to give a shot. The user manual was user friendly enough to be able to clearly instruct me as a new driver of what to do, surprisingly the set up was quite simple and materials feel like high quality stuff. and it even comes with a bright LED light, a mini compass and a built-in piece of metal to break the window in case of emergency! Love it!

I just used this product 2 weeks ago to jumpstart my car battery. It was very convenient that I didn’t need another vehicle to help jumpstart my vehicle in the parking lot. It was easy to see use and works great. Finally I used something as an emergency situation that save me a lot of time to be back on the road without waiting for roadside assistance. It can also be use yo charge your phone wireless or wired through USB port.

I bought this jump starter for my car and I haven’t use it until today.Today I have a power outage in my building and the generator does not turn on, the problem was that the battery does not holds enough charge, so I decided to try the jump starter with the generator and boom it started the generator without problem.I highly recommend this jump starter.

I’m sure everyone has had their car battery die on them at one point or another. Hopefully never, but for the price and quality of the product and something that will be needed in case of emergency, I highly recommend it.I’ve done some research and compared to jump starters, this is by far the best value I found with multiple use that comes with a nice case.

I originally had a hammer that jumped off three cars on one charge. After the third I got no display, no flashlight and no help on this problem anywhere so I bought the the Jstar 4 which I haven’t used yet. Seems to be a great product if it continues to work. I have used it and jumped off 4 cars before re-charging. Works great. Well worth the money.

I bought this unit because it’s all in one charger, I can use it to charge laptop, phone, tablet and most important it’s portable jump start. Gone are the days when you have to carry heavy battery to jump start the car. The charge holds for good amount of time. Good buy, it also charges rechargeable flashlight and it didn’t deplete the charge indicator of the jump starter. On top of it, it has a very bright which is helpful in dark.

The best damn charger you’ll ever have… I have jumped over 30 cars since I’ve owned it, saving lots of people one of their roadside assistance jumps of 3 per year complimentary only. a jump after using the 3 up! It pays for itself in 1 use!! Buy it never ok nice has it failed to start a car even with . 08% left of charge! I should be your salesperson!! Ha ha ha I need a job .……really!

This is a nice portable charger/jump pack. I like all the features but the voltage test feature and the added wireless charging stood out to me that are not found on many other models. It is going to come in very handy on an upcoming camping trip. Hopefully we don’t need to do any jump starting but it gives an extra peace of mind to keep our devices powered and that extra just in case should the car get drained down as well. Looking forward to testing it out.
