[This review was collected as part of a promotion.] I received the batter jump pack from gear wrench when I got it I was surprised it was small and lightweight compared to my other jump packed I had I jumped dozers and tractors at my job with ease from completely dead batteries from the lights left on from last night I got to use the 12 volts and the 24 volts systems and the jump pack started up both right away and I also love I can charge my phone while I’m on the jobsite so I don’t have to worry about my phone dying when I’m working also a plus I love the light it helps out when you forget you’re headlamp overall I would recommend this to everyone from a diy to professional kind or work it’ll be good to carry one in you’re personal and work truck.

[This review was collected as part of a promotion.] The GWLBJ30 is an awesome jump pack. It’s lightweight, it’s powerful. The display stays well lit and easy to read. The pack can handle dead cars and trucks with easy and the charge on it lasts a good amount of time. The light on the back is great if you’re broke down on the side of the road at night or if your other lights are dead. The USB and the 12V outlets are an awesome touch which is another great reason to pick one up

[This review was collected as part of a promotion.] Works well. Sold jumpstart ability of its size. Took no time at all to jump my wife's 2019 GMC Terrain. I feel this has very good value for its size. Its fairly compact compared to other jump packs of similar size.

[This review was collected as part of a promotion.] I wanted to try the GWLBJ30 since we often have issues starting vehicles and equipment in the cold. The compact design is very handy when starting a vehicle that may not be close to the garage. I was impressed with the multi voltage capability when using with deisel equipment. The use as a powerbank is another great feature that I had not had with previos packs.
