Description

About UTRAI UTRAI, an independent brand born in 2014 and has been focusing on the auto parts industry for many years. We have designed a large number of auto products and sold them all over the world, and are committed to providing the best solution to any auto problem on the road. Whether it's an outdoor trip or a roadside emergency, you can trust us and get everything you need from UTRAI. Always Ready for Your Adventure! What should i do if the jump starter is not working? Please checking the user manual first, or find us through the user manual, our engineers team will solve your problems as soon as possible. The air compressor preset only goes up to 50 PSI? • Switch to Custom Mode to raise the preset value—up to 160 PSI. • To prevent over-inflation, Car Mode limits the maximum preset to 50 PSI. • If using inflator for extended periods, it's recommended to stop in every 10 mins to cool down it. Why do the smart clamps get hot during a jump start? • It's normal to get hot when starting larger engines or after extended cranking. Limit each attempt to 5 seconds. If two attempts fail, wait 2 minutes before trying again. • The smart clamps and the unit feature built-in overheat protection. How should I maintain my product? • Full Initial Charge: Please fully charge it before first use, as it may have run out of power during shipping and storage. • If it is not used for an extended period, please charge it every 3 months to maintain battery activity. Why is the button on the detachable magnetic light always red? • It automatically charges when reattached after use, and the red light will turn off once charging is complete. • Push the button on top of the light panel upward to easily detach it. Long press the light button to turn it on/off.

  • Compact size starts a big truck USB-C charger
Color: Red
A day after I got this, my neighbor needed to start his truck, which is a big truck. I said I just charged up this unit. It’s great cause it charges on a USB-C so that means you can even charge it in the car. It went to like five bars fully charged. When he used it, it started his truck up immediately which he had had problems with with another jumpstart and when he got all done, it only used one bar. So impressed that he took a picture of it and said he was gonna order one on Amazon himself. It’s a small unit, but it packs a good punch. I must admit I haven’t tried the air compressor part completely only a test, but it seemed to work fine. The jump cables actually snapped in and out of the main unit so they’re not always connected so you have to make sure you keep them in a nice bag that comes with it altogether in your car. Just remember to take it out every now and then and plugging into your USB maybe in your car to charge it to keep it top notch ... show more

  • It does everything they say it does
Color: Red
This thing is a great little item if you're car needs to be started right up it will do it if you need air in a tire it will do it, if your car tires are low it struggles but it will do it but it will drain the battery if you have to fill up two half full tires but I still give this item five stars because I like that it comes with the magnet light on the side that helps a lot with jobs under the car and under the hood and it also has the USB ports those are great for charging and other things I use a fan that I plug into it while I'm working and if you also ride motorcycles or scooters the clamps also fit great on the smaller batteries as well I think it's a great product all around five stars for sure ... show more

Excelente producto, me sirvió para inflar un caucho de una super duty y también encendió muy bien la bateria.. cumplió las expectativas y mas , lo recomiendo 👌 Si lo usas por mucho tiempo inflando las llantas me encanta que tiene un sistema de apagado para que descanse el Utrai y no se queme , lo dejas reposar y vuelve a funcionar con potencia ... show more

I love this product. The compressor fills tires reasonably fast! It’s not loud, the magnetic flashlight and safety light comes in handy. Honestly it’s the best value for your money. Not cheaply made
