Keenpower Portable 12V Car Jump Starter Emergency Battery Booster Pack Charging Outputs (Black/Red/Yellow) B600

I bought this for my wife. The old, heavy and bulky, easy to make a mistake one she had wouldn't hold a charge anymore. She loves this new unit because it ABSOLUTELY prevents her from hooking it up wrong. Even the battery clamps are well made and designed to prevent shorting out. The fact that it is compact, light weight, has a great carrying case, will run/charge every electronic device (you get connectors for everything) around, and delivers strong long lasting power makes it truly perfect for everyone. This is the unit I will buy for myself as soon as the heavy and bulky, easy to make a mistake one I have dies.

Excellent device. Have an old 3rd vehicle with V6 I hadn't driven in a while. Battery was shot. Tried to jump start it with another vehicle but never got it to start. I used this power pack and it started right up. I had to make two more stops along the way to get the new battery and it worked every time. I believe I used it for 6 starts and the power indicator only got down to 5% charged.

Prior to this I had two different chargers for our cars. Mine was a Tenergy Storm LiFePO4 based unit that is now 3.5 years old & my wife had an Anker Li-Ion based unit that was also 3.5 years old. Her unit had batteries that puffed up (double in size) so since my LiFePO4 based unit was still functioning my mind was made up to find her a unit that used the same kind of battery technology.This jumper Starter was the answer & will be the one I buy (hopefully after 5+ years with the other LiFePO4 model). We haven't had to put this one to the test yet. We did charge it for about an hour as it wasn't fully charged when it arrived. I like the addition of the Ec5 socket adapter which should make plugging in some other devices easier. I can use the various tips that came with the Anker unit for this one (if we need to).

I keep this in my V8 6L truck and had low expectations but it came through! It started right up but I'm sure the battery was not completely dead. I've also used it several times when strangers had issues in parking lots, but those were small 4cyl cars. It says it can start the car several times, but I have tried to use it on a large Generac generator and only been able to start it once without needing a recharge. I like this unit so much that I purchased a second one to keep charged and rotate which one I keep in the car. You NEED to keep this charged and I recommend topping it up every month or so - especially in the cold.

I got this as a Christmas gift and got to test it out yesterday after my battery died coming out of the grocery store. It started my car immediately and was super easy to use. Hold the power button until the lights come on then when your ready to jump the car hit the vehicle button until you see a green light. I used it again this morning to jump my car to go get a new battery. I'm going to buy a second one to keep in my truck.

I bought as a backup in case my car battery runs out and I can't get someone to jump my car immediately. Also realized it has a plug that I can use to charge my pad and my phone, which is a bonus! The jump starter works properly. Received promptly. Everyone should keep something like this in the car in case of emergency!

This might work for something small like a lawnmower, but it did nothing for my car. I'll probably use it for other things like camping.

I used to use jump cable but it is too much hazzle to use car battery to jump start especially when the parking spot is not easily accessible. Now I bought this jump starter, it is much easier to jump a car. And I am more pleased to see this is not only just a starter, but a power bank for phone! Great design! That's another level of security feeling now when going for a road trip as now my car and phones batteries are both covered!
