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.

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.

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.

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.

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 ezysurvival.com 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.

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.

Impeccable, a démarré ma clio sans soucis. La charge est passée de 100% à 63% après le démarrage. Je pense qu’il vaut mieux le recharger après chaque utilisation. Rechargement rapide. A voir dans le temps mais pour le moment je valide 👍.

Très pratique, nous a permis de démarrer notre 4×4 Land rover freelander sans problème.
Permet également de charger un téléphone et possède une lampe très puissante.
Très facile à utiliser et le prix n’est pas excessif, à posséder dans sa voiture.

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.
