Schumacher Electric1000 Peak Amp 12V Portable Lithium Car Battery Jump Starter & Power Pack - Lithium Ion Jump Box - with USB Charging & LED Emergency Light - SL1639

Worked perfect to start my big van, after leaving the headlights on, and was very easy to connect to the battery. It easily stores under my driver seat for easy access. It is pretty light and felt sturdy. I plan on taking it camping with me to charge misc items when electricity is not available.

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!

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.

This worked great to start my car battery. I watched the How-To video and it started my car the first try. Used it to charge other devices too, like my phone. In warm weather, I kept this in my apartment till I needed it; Then kept it in the trunk until I could buy a new car battery. But then I moved to cold weather. Caution: best not to leave it in the car trunk in cold weather; If it freezes, it is broken! Worked great until then. Only downside was the rubber coating disintegrated after awhile... as in got sticky and was getting like melted rubber. Maybe from salty air (by the ocean)? I had it for several years; worked great till it froze in a midwest winter.

Performs as expected but very slow to charge.

These hold a charge for a long time, and have several uses as jump starters and backup power supplies.

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.

Fantastic. I bought it a couple of months ago and it was easy to charge and compact. I kept it in my trunk until two days ago when my battery died. It was easy to use and my car started on the first try. The charger still had 92% charge after the jump.
