Easy to use slightly heavy
Works great and easy to use. Able to jump multiple vehicles on one charge.

Made it 11 months
We are a professional mechanic shop and have been in business for 21 years now, and this is our 4th box. Previous box is same brand and still works, it's just that the built in 110v plug in charger port for that box (really like that feature, no external charger needed) no longer would charge the box, so we (thought) upgraded to a nicer model (this one I'm writing the review for). Seemed to work great for the first 6 months or so, would even start dual battery diesel trucks with no issues. Then it wouldn't do the diesels every time, we attributed that to "maybe the batteries are just totally dead or had shorted cells" because it worked sometimes. I should have recognized at that point there was something up, but we don't work on diesel that often, and the box was still starting cars just fine. The box stays plugged in whenever not in use (like the instructions stated) and it always says 100% when we go to use it. Just noticed 2 months ago now it will only start something that is partially low, like when you get the starter that just clicks during cranking and will not turn over. Last month, now it won't even start those, let alone a car that had the key left on overnight. I had figured due to the more expense of this box, it should be even better than the last box, but apparently not. Very disappointed. We went back to using the older box for now, have to hook up a charger to the clamps and turn on the box to charge it, but still works, going on 3 years now. Guess they don't make stuff like they used to anymore...

Great piece of gear...with one very minor shortfall.
Built tough and unlike many other similar models, the cables are long enough to get into the battery box without having to get a stepladder to set the jump starter on!! Fortunately, haven't had to use it yet. If I had any complaint is that you need to use as external charging unit (included) to charge it up. Would have been a cleaner design to just have a twin blade Edison on the back.

They last less than 6 months!
I have 4 of these and none of them work now. These work great when they are new and they will start just about anything only catch is they last about 6 months and stop working. My first two I returned within the Amazon window and they are bad now also! I keep them charged the way im supposed to with no luck. Now we can grab one that reads 100% charge and it wont start a lawnmower!
