The YUSMAN Car Jump Starter has been an absolute lifesaver! It's small and compact, easily fitting under the car seat or in the glove compartment (once you clear out the gloves). Despite its size, this device packs a punch and has consistently proven its worth by starting my car whenever the battery runs out of juice.

Lo he utilizado 2 veces de momento y el resultado ha sido muy bueno. Arranco a la primera . Los cables son gruesos y parecen de buena calidad. También tiene en un frontal la linterna que es bastante potente. Y tiene varios modos de luz. Tiene blanco. Luego intermitente y también de 2 colores rojo y azul. La pantalla de carga es grande y los números que pone son grandes y se ven muy bien. En la parte posterior tiene las tomas para recargar trae 2 USB y un c.toma de móvil. También sirve para cargar otros aparatos como móviles y tablets. Lo probé con un proyector portátil y también va muy bien. Viene con una funda robusta. Se permite guardar en cualquier lugar porque es compacto. el peso es muy reducido en comparación con otros que visto. Los amperios que trae 5000 son suficientes para cualquier coche o moto . La carga de la batería se hace bastante rápida. De momento buenos resultados

I bought two of these on a black Friday special and I'm glad I did.I have already used one multiple times to jump off an old battery in a truck that I don't drive very much and after 2.5 months and about 4 jump starts, the jump starter still has a little over 90% battery life left.Also the jump starter clamps have a built in battery voltage display. It has two ports for charging cell phones or other items, a bright built in LED light and a big LCD display.The thing I like the best about it is it's a fraction of the size and weight of the old lead acid jump starter it replaced, plus it has a little over 5 times the amps of the old jump starter as well.For the price I paid, plus the performance of this unit, I am very happy that I bought this battery jump starter.

So very happy with this booster. I have a booster thats a couple years old and the size of a gallon of coolant. It was unable to jump my truck. Close, but just not able this time round. I ordered this jump starter and it arrived quickly (surprising for the holiday season) Small and compact. it was 71% charged but I charged it to 100% which took basically no time at all. Charges up pretty fast even though it's by USB. Connected it up per the instructions and just like that, with so little effort, my truck started right up. And it was 23 degrees out.Easy to use, every older vehicle should have this in the glovebox.

Easy to read instructions, easily charged, and gets the job done. Have jump started a few coworkers vehicles and it had plenty of juice. Battery life is great, had been sitting in my vehicle for 3 months after my road trip and used the strobe light for 3 hrs helping divert traffic at an accident while we waited for authorities

Product is everything I hoped for. Convenient carrying case. Came charged to 80% though I completely charged to 100%. Started the car quick and easy. Alittle tight putting it back into the designated space but I made it work. Great product.

I never write reviews, but I feel the need to on this item. I always do my research on just about every item I purchase , and I did on this one to. I watched all the videos/ reviews I could find on it and it had a great star rating.Brought it on July 17 on a prime deal day and have used it only 3 times to start my mower. Went on today to jump my mower and would not turn on, so figured it need to be charged so put it on charge and after an hour or so it read 100% while pugged in. Took it off the charger and it won’t turn on no display nothing. Got on my Amazon to get a return and it says return expired on August 17. So I can’t even return the item. It is sold as an emergency item which I just bought it for jumping a few things aka mower around my house and it couldn’t even handle that three times.

This is a great thing to have so you don't have to depend on someone else.I bought this to jump a car that's been sitting for a while and got it up and running right away.A few things I have to say.1. It's very compact and easy to store.2. Very easy to use and not complicated.3. The flashlight on the end is nice one to see but for 2 just so it helps people see you from a distance.4. This is one of those items that gives you peace of mind when driving or if you have other family members. It's something I've wanted for a long time and I'm glad I have one now.5. It has a nice carrying case to keep everything together.Overall this is a great item to have and I would call it a must have tool for anyone in a family. It just will make you feel better knowing you can jump your own car or a family member can.

So I have a problem with the cold weather killing my batteries. Its not uncommon to go out in the morning and try to crank a car to find the battery isn't charged enough to crank the car. then i have to go through the hassle to to get the charger out and run cables outside and plug it in while I get ready for work. I had a car thats been sitting for a few months and the battery was fully dead. Wouldn't even turn the lights on when I opened the car door. Well i hooked this jump starter up to the car and it was able to jump the car and I was able to crank it and move it. I was pleasantly surprised as I thought it wouldn't be able to do it. Highly recommend this jump pack. I will come back and update my review if it fails in the next few months or I run into any issues.

Llevaba tiempo buscando un arrancador de coches porque lo necesitaba para mis vehículos y finalmente me decidí por este modelo ya que tiene muy buenas prestaciones y no me he equivocado en absoluto.En primer lugar, el equipo viene perfectamente integrado y protegido en un estuche de transporte de un tamaño reducido donde puedes llevártelo a cualquier lugar cómodamente.Una vez abrimos el estuche nos encontramos con el arrancador, las pinzas, cable USB tipo c, manual de instrucciones y enchufe tipo mechero.El uso es muy sencillo, se conectan las pinzas al arrancador, se conectan los bornes positivo y negativo a la batería, se enciende y ya estaría listo para arrrancar nuestro vehículo sin ningún problema. Lo he utuilizado en un turismo y en una motocicleta y ha funcionado a la perfección arrancando ambos vehículos.Con una sola carga de batería puedes usarlo varias veces. También ofrece una linterna de alta potencia con varios modos de luz y dos puertos de carga usb para cargar dos dispositivos externos simultaneamente.En definitiva un gran equipo que nunca puede faltar en tus vehículos.
