This seems like what a jump starter should be. Very strong. I jump started a dead Audi that was sitting too long. Turned over faster than a normal fully charged battery and started right up. I love the volt meter, which is so useful I wonder why other jump starters don't have a meter. Nice clamps with longer than average length. I have two of these units now.
Had the Lokithor J401 for a month when my lawn mower would not start. Hooked up my Lokithor J401 and it started right up. Been setting in my car for a month and no problem. Very convenient. Bought this one after watching YouTube video's. Seems powerful enough and one main thing I liked was the fact that I could read battery voltage with this unit. After you get car started you can see if car is charging at the proper voltage.
Jump started my dads 3.6L van up no problem, and is compact enough to fit on the arm rest center compartment
Pleasure to do business with
Have jumped multiple vehicles without having to recharge the unit. This is a 10 PLUS in anyones book.. Great design as well.
