Awesome Jump starter!
I'm a field service mechanic who works on heavy equipment. This jump starter can easily jump start any of my large pieces of equipment. It works immediately and gives me no problems! This is a great investment! I would recommend it to anyone. It also easily starts any standard vehicle as well. Very versatile.

Best starter money can buy.
Came on time and was nicely packaged. Have used it once and it worked great. Nice having a compact jump starter that can be used on our truck and car. Highly recommend.

Good purchase
I’m a truck driver. This jump starts both my car and my truck. Wish the cables were about a foot longer but gets the job done. Well worth the money.

NO WARRANTY DO NOT BUY
absolute junk, will not hold charge after 2 months and the support will not respond to and warranty claims, ive sent multiple emails requesting warranty with no response, so this thing basically comes with only the 30 day return warranty through amazon, spend a little extra and get a better quality one, and the charger for this thing is trash
