i am so happy with this purchase i was skeptical initially but i love my car adapter it's super convenient and it works well so far i have had no issues using it it does exactly what it is supposed to keep my work laptop charged while i am in the car we had a long trip and it worked perfectly in the car i haven't used the car charger yet but it is as described and directed quickly the part i like the most is that it comes w three different plugins i'm using for the laptop and one of the plugs fits into the laptop perfectly and if i have additional prodiux i won't have to keep buying different charges to fit each different electronic i use this with an hp laptop when operating ham radio digital modes while off grid this allowed me to recharge the laptop from a portable battery box fitted with a 12vdc outlet because this is dc to dc it's going to be more efficient than using the factory a
