It's a little clumsy in my RV lighter socket it works, but sometimes you have to push pull it in and push it out. I don't think the metal that attaches it is enough there. I think they should have maybe three strips instead of just two because it's flimsy, but it's durable at the top where all the connections are I just wish the other part that maybe they should not make the hinge or the the Joint so loose maybe that could be tighter otherwise it does what it supposed to do and that's tribute to me so I still have it four or five stars

I have used a higher power version of a similar item in the past, I was very happy with that product so making this choice was relatively easy and it was made even better when I saw that it was discounted over five dollars from what I was expecting to pay

Savin the day

During. A power outage after a tornado, this was ideal for charging laptops and other electronics that need a higher draw than typical car usb outlets. Kept me powered for a week. Excellent tool to keep in hand in an emergency or travel kit
