Stanley delivers again! :D
Excellent device, works GREAT! Doesn't take up much space, either! I actually put it in my back-pack and use it to charge (run) my 10" tablet, my phone, and other portable elect. devices. Sturdy and the flashlight is the best one I've had in a long time. Recommend it to all my customers who want a charger/jumper/recharge device.
A Life Saver!
Bought this for emergencies and would recommend this oroduct highly. purchased in 2018 and its saved me several times. In fact, after all the rain during Hurricane Nicole, I just had to rush out to get my daughter's glasses to her. My car was dead! In less than 5 minutes i was on my way! I'm getting one for my grandson, as well as others. A life saver for sure!
Started my car on first try.
I went to another state for work for three weeks. Must have left the interior lights on when grabbing things from my truck. I got in it and turned the key to find out my battery was dead. Put the jump starter to use and it worked as expected. I like that the cables are longer than my other jump starter I have in another vehicle.
