Schumacher ElectricLithium Jump Starter and Portable Power Pack, SL1642, 3-in-1, 2000 Amps, 12 Volt, 2.4 Amp and 3 Amp USB Ports, for Car, Truck, SUV, and Marine Batteries

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.

This is a fabulous jump starter with the Schumacher name on it. It is a perfect addition to anyone that has a vehicle they need to start that has a dead battery.

Everyone in my family has these and they are great to jump off your car and trucks and can even charge your phone when you loose power at your house.

Keeps a charge for a long time and fires up auto quickly. Not needed often but great to have when you need it!

Works well

Surprising power that makes everyone I help want it

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.

Works great very handy
