[This review was collected as part of a promotion.] I was impressed with how well it worked. I was worried that the plastic clamps might not hold up, but they were good. There l’s even instructions printed on unit so you can use it easily. It had plenty power to jump my van multiple times. The unit is lightweight and easy to use and store.

[This review was collected as part of a promotion.] Excellent little jump pack. Its stong enough to jump my 5.7L truck. I use it to jump 3L deisels and ive used it to jump my 6.7L work truck. Ive found it works best jumping newer vehicle it can struggle if you battery is below 9v. But if you let it sit for a couple minutes it will fire the truck up.

[This review was collected as part of a promotion.] Effective little jump start pack that doesn't weigh a ton and packs away small but can still start large engines repeatedly. Jumper cables connect easily and securely with just enough length to get where you need without adding bulk. comes with a bag instead of a bulky case

[This review was collected as part of a promotion.] I work as a Master Medium/Heavy Truck and Equipment Mechanic for a City in Orange County California. We are a busy shop with every kind of equipment from JD Gators to Payloaders. I have used the GWLBJ20 at least 20 times since I've had it to include charging my iPhone and other devices. This thing is awesome! I've dropped it and almost crushed it once. It still works fine. The flashlight is helpful. I also volunteer on the Marine Corps Base as an Advisor for the Automotive Skills Center. We have used it probably another 10 times there. Everyone loves it. I'm going to buy at least one more of the same unit because it it so useful and light. My other jump pack is heavy as an I beam and doesn't work that good.
