Title: Powerful and it gets the job done!
Review: This is an amazing thing to own! I bought it @ a year ago and just used it recently to jump start a car. Very powerful. It failed to start the car the first 2-3 attempts. I had do the “turn all electrical things on” in order to start the dead battery. It worked beautifully. Started right up! It is small, handy and does the job. Every woman needs one of these!

Title: great jumper
Review: i bought it for my motorcycle, it will work on cars as well, but i bought it to carry on my adventure biking trips, it has already saved me, i was testing my heated gear to see how much amperage i could pull from the stator without killing my battery, and i took it just a but too far, with full heat, heated grips, heated seat, high beams, aux lights and add on fog lights. when i stopped to get gas, my battery had dropped to 11.5 which during cranking went to 10.4 which is not enough to get the computer to turn on.. hooked up the jumper and it ripped right over.. also i can use it as a mobile 12v power bank to heat my heated riding gear away from the bike… and has usb charging ports for other stuff, and the led light is handy as well.. it will be great insurance when im in the middle of nowhere on the bike.

Title: It was a great product, until I used it.
Review: The first 5 or six times I used the jump box. It worked perfectly, couldn’t of asked for a better product. Infact the jump box was so powerful it even cold started my New Holland 5610 tractor. I was amazed…I woke up one Saturday morning around 7ish , wanting to get some much need yard work done,. Being early spring. As I prepare my Cub Cadet lawnmower for the task of cutting knee high weeds, every stick, branch, child’s toy or tree that will be in sight of the Barefoot family yard.. for the fortunate none North Carolinas. that’s all the beautiful yards will grows the early spring of North Carolina.As I turned the ignition key to start, nothing happened. I quickly realized, “yes ” the battle dead. No problem right. I have a new amazingly powerful jump box. I quickly applied the +’red’ to the positive termamal. Same process to the negative. I firmly grabbed my trusty jump box and pressed the center button to activate the device. The center button became stuck.??? I was confused, I taped it softly, repeated the taping over and over again. Same result. I tried a small flat screwdriver to pry on the sides and edges of the button. My attempts were in vain. I slowly gave into the fact my new amazingly powerful, impressive and perfect in my eyes, had failed me so soon. I now shamefully avoid friends and family for the fear of my failure jump box will be brought up in conversation. I am taking the disappointment day by day trying to void it from my memory of the power I once could yield freely and boastful. As time slowly drags on , the one light that keeps me going is the one year warranty I have shamefully applied for. I often look back on the days I could laugh at week or dead batteries. My one hope for redemption is a lone email that was sent to a manufacturer name I dare not say. I will continue to attempt being strong through the trial of my future on cranking trucks, lawnmower and even tractors again some day.

Title: Powerful
Review: No problem jump start motorcycles with this. Battery seems to last a long time so far. Good quality. Only thing I wish was a little different is the plus that plugs into the battery pack for the cables. Itâs kinda big so makes storage and fitting in the bag not slim and easy. Not bad for the money. Only charged it when I first bought it and jumped at least 10-12 bikes and still showing over 75%. Charges up quick

Title: Impressed Me
Review: This is the first jump starter I’ve owned. I’ve got a high performance car that doesn’t get driven often, so the battery is usually dead by the time I drive it again. The car has a big V8 with lots of cams and valves to get moving, so it does need strong cranking amps to get it started. This thing started it up with no problem twice without a recharge and was still showing 90% charged afterwards. I think I could’ve started the car at least two more times without recharging the jump starter, which would be big feat. I bought two of these at black Friday deals. I’m thinking I should’ve bought more — one for each of my vehicles. Guess what I’ll be looking out for next black Friday? It is small and doesn’t take up much space. The only question I have is longevity — how long will it last? That is to be determined but so far, so good.

Title: holds a charge
Review: I jumped 3 vehicles with one charge. The charge seems to last forever!!!!! also can charge you phone with it. I bought 3 more for X-mas gifts, gave them to my kids so they could put them in their cars when going on trips or just to the store.

Review: Se descompuso al segundo mes y ya pasó el periodo de devolución (1 mes). No lo compren, la luz Led verde se queda flashando y no te dejará arrancar el vehÃculo.
