KeenPower Portable Car Jump Starter Emergency Battery Booster Pack Charging Outputs (Black/Red/Yellow) (900A RED)

I wanted to hurry in after this final failed attempt at starting my car which registered a weak, not empty, WEAK charge. I wanted my anger at this useless device to be at its peak. In my experience using this jump starter, it absolutely does not jump start my car battery. I made sure I did every connection, every step exactly as described and instructed. No mistakes!! Folks, this Keen Power Jump Starter Wil not jump start even a partially drained battery. The flashlight works, but the intended purpose of it absolutely does not. Now I'm stuck with a $70 flashlight/paperweight. Buyers beware! This thing did not work for me. Learn from my mistake.

Everyone should have a good quality portable jump starter in their automotive arsenal. Takes very little space and can really save the day. This unit is more powerful than many that are sold at a higher price. Well built unit with easy to follow instructions. Even a nice carrying case for it and all accessories. Charges up quickly after use although it can hold a usable charge for months. Great for starting dead/low batteries in motorcycles, riding lawn mowers, atvs, etc. as well as cars and trucks.

Used one time and it dtarted the vehicle. Second time using the jump starter i power on and press the jumpstart button it shuts off. The unit is fully charged and i even tried it on another batter it just shuts off.

I didn't try it yet but it looks like a high-quality product. It shows 75% charged right out of the box. A good caring hard nylon folder in which you can add a few items for the road.

The manual says that the 900A battery is not LiFePO4, as stated here, but LiPo, which is a lower quality battery and does not have the temperature resistance I am looking for. The manual says only the 600A battery has a LiFePO4 battery. Returning the item.

Not as powerful as expected. It's plug to charge it is fragile. Mine broke pretty quick, which makes it unusable now.

What I dislike about the product is the port where you charge this product the pin broke making this product not usable to use again .

Start my car right up in the cold weather. Easy to use
