I have a 2012 Chevy Volt for over ten years now and during that time I burnt out several of the 110v 15amp wall chargers. All were replaced free of charge by Chevy or the dealer but the last one I took apart and replaced all the friend wires with better ones. To my surprise it has been working fine for years but since my warrantee expired, if something goes wrong and I need a new one, a replacement costs $500.00 from the dealer. Even used cost more than this one. I got this one from Amazon a few weeks ago for less than some sneakers and it works great. It does not have high or low output, just high. It does not have any ventilation holes so maybe good for bad weather. I plan to keep it as a backup in the car because I still use the original charger at home and leave it plugged in it every time I go. I am using the VELVOR at its Level 1 level and it works find. Wires look strong. 25' is comfortable and it appears to be water resistant since there are no ventilation holes anywhere. Excellent price.
