## Questions & Answers

**Q: Is the jump starter compatible with both gas and diesel engines?**
A: Yes it is but there is something you should know the jumping amperage should be checked so you know if it's too strong.

The upside is that I can jump anything and have helped out many people, but the downside is that it's really hard on my battery.

A: Its 1.43 lb by itself and its reliable just keep the jump starter capacity above 75% charge before jump start your car

**Q: Can it charge my laptop?**
A: Yes absolutely you can so long as you have the right cable. Anything that takes a charge, if you have the right cable this will charge it like the wall would...it charges up a car for gods sake

**Q: Does it require an adapter to charge?**
A: Yeah, it require an adapter, and it is not included. you can use your own adapter to charge the jump starter.

    Unit Works Well, With A Few Minor Complaints
  

*by F***E on Reviewed in the United States on April 13, 2024*

I purchased this based on the experiences we had with a lower amperage unit purchased for my son. His has worked great for 6+ years. After opening the box, I was disappointed to see that this model comes with a storage bag, rather than the nice fitted hard shell case that was included with my son’s model. I had the chance to use it almost immediately after purchase and it worked fine to jump-start my truck. The one glaring shortcoming I noticed is that the status lights are extremely difficult to see in direct sunlight. Also, the jumper cables are a little short. A couple more inches of length would be nice for when you have to connect the clamps at odd angles. Overall, just some minor complaints. If it works for as long as my son’s, I’ll be happy.

*by D***E on Reviewed in the United States on April 15, 2024*

I have charged this thing 3 times and can’t get it to take a full charge.  97% is best I can get.  Not to happy it won’t fully charge since my truck is a Diesel and needs full charge
