What’s Good, Bad, and Ugly About the Yaber jump starter? An In-Depth Review

Convenient for Emergencies: Many users have found the YaberAuto Jump Starter incredibly handy during roadside emergencies. As Bludevil shared, it has been a lifesaver for jump-starting cars and even includes a built-in air compressor. This combination has made it a reliable tool, “especially if you store it in its hard case.”

Compact and Portable: One of the standout features of this product is its compact size. Oliver appreciated how it comes with a “carrying hard case that conveniently stores all attachments, cables, and manuals.” Despite its small size, it packs a punch, making it easy to carry around in your vehicle.

Versatile Usage: The versatility of this jump starter is a major plus. Tracy A Ouellette noted its ability to handle various tasks efficiently. It can jump-start vehicles, inflate tires, and even charge phones, making it a multi-functional tool. As Brian remarked, “it’s a good product” with a “strong pump” and intuitive design.

Issues with Air Compressor: Several users have reported problems with the air compressor overheating or not working effectively. Leigh mentioned that the compressor got “extremely hot to the touch” when filling a tire, making it unsuitable for larger vehicle tires.

Reliability Concerns: Some users have experienced reliability issues with the product. Amazonian shared their frustration when the inflator didn’t work during an emergency, leaving them stranded. Another user, Janice Mcdonald, noted that the charger stopped working after six months, questioning its long-term durability.

Overall, the YaberAuto Jump Starter is a valuable tool for emergencies, thanks to its convenience, portability, and versatility. However, users should be cautious about its air compressor’s effectiveness and long-term reliability.

People find the following negative one quite helpful. Reviewed in the United States on July 13, 2024 by Leigh, titled “Overheats when filling tires”
Great for the jumper box part of it, jumped my van right away! HOWEVER, when filling just one tire it overheated…I’m talking extremely hot to the touch, BE CAREFUL! I could see it being handy for smaller tires like trailer tires or even filling an inflatable pool but would not recommend for car, van, or truck tires. So that’s why I gave it 3 stars…great jumper box, not great for vehicle tire inflating.

    After 2-3 times used, I recharged it to 100% for a day, after 3-4 weeks it lost all the charge

    Asking the manufacturer; Is it normal after 2 months (I cannot return it now) and 3 times used and fully charged, the device to be drained? I used it 3 times, after I charged it according to the manufacturer instructions, I jumped an suv with no problem and inflated two tires. 1-Jumping a dead car was no problem except that the cables from jumper to car battery are too short. 2-When I tried to used it two weeks after I fully charged it, its battery was drained so I have to recharge it for a few hours in order to inflate a tire. Wow, and what you do I case of emergency when you are on the road!?! Not reliable at all. 3-Also not intuitive at all, the third time I had to read their instructions again to figure out the sequence how to start to inflate the air. When asking questions, the seller/manufacturer did not answer. I hope they will honor their warranty. Maybe Amazon it will take it back for a refund because this is not a reliable product.

    Works great, feels durable/ strong as a bull

    The media could not be loaded. I started our car in less than 3 seconds, after it sat in freezing weather for a week with a damaged battery caused by ground wire failure. I had to replace the battery eventually but it cranked the starter like a chipmunk on crack. For reference, 4 cyl, Hyundai sonata. Also I’ve used the air compressor to inflate multiple vehicles and mowers etc and have had no problems at all it works perfectly. I’ve only noticed a loss of about 1% of battery drain per month so I recharge it every couple of months. It takes 6 hrs or more to charge fully. Great product, fits in my hand and is all around cool

    This is a great product, I have not yet used it for jumping my car but I used it several times to pump my bike. My road bike pressure is 100 to 115 PSI but the pump for the bike is setting 45 to 65 PSI, this is not a problem. I have found that I can customary to set inflation pressure to 700 to 805 Kpa, which is equal to 100 to 115 PSI. Only a minute can be finished. I like this multiple-use device, I believe it can boost cars as well. My only complaint is that the digital device is not easy to use. You have to read the manual carefully. to figure out how to use it.

    Battery life

    The unit does what is advertised but barely. It takes a long time to pump anything up and it likes to shut itself off often so you have to start it up multiple time to finish inflating what you started and the inflation feature drains the battery really fast. Surprisingly the the Jumpstart feature doesn’t drain much battery but it doesn’t last long either. It also shuts this function off automatically after about 1 min of runtime.
