Rudolf Kirsch –
The package arrived surprisingly quickly. The utrai jump starter works exactly as described. It came almost 80% charged, and topping it up to 99% took about two hours. I have no complaints. I started a 1.6 petrol engine with a completely dead car battery on the first try, and the device’s battery level dropped by only 1%. Definitely recommended.

device worthy of recommendation. good workmanship and instantly starts 3.2l engines without a sudden power drop on the power bank. readable display and the ability to check battery voltage.

Super product, the Audi 1.9 diesel really started with a jump start, I was even surprised by the power of this device, and on top of that, 2 smaller gasoline engines, a POY 1.2 Hyundai with a very weak battery, started even better than with a new battery. I really recommend it.

I just had the opportunity to test the device. My wife left the car on for over 5 hours. The battery discharged so much that the starter only turned once and that was it. After connecting the device, the car started immediately. It went from 100% charge to 97%. The car is a Kuga 1 2.0 tdci diesel.

Hello

I highly recommend it.
Utrai JS-4 starts everything, whether it’s a diesel or gasoline car or a farm tractor, easily started two farm tractors at -2 degrees, one with a very weak battery and the other without a battery, and still has 100% power. I am very satisfied with the purchase.
