Nice extra battery pack, been taking on locations.

This thing is nice, you have to drain before recharge, so charged up a couple phones and a tablet before 0%. Right now charging the Dremel. Has nice safety light with compass in case taking out on an adventure, who knows maybe someone might need a boost along the way.

Compact, powerful, and a great emergency tool!

I was honestly skeptical that something this small could actually jump-start a car, but it exceeded my expectations. It was extremely easy to handle and, most importantly, it started my car without any issues. The compact size makes it perfect to keep in the car for emergencies without taking up much space. I also love the added features: you can charge up to two USB devices directly from the unit, and the bright built-in flashlight is incredibly useful, especially in an emergency or at night. For its size and versatility, this is a must-have gadget to keep in your car. Extremely satisfied with this purchase and definitely recommend it!
