i was out looking for a new charger for my scooter, when i fell upon this item. so i checked it out, and it was about $40. pretty expensive. i ignored that, but bought it. when i received it....2 DAYS LATER, i tested it... it didn't work. so i was very confused and upset. so i left it there till about the evening. when i checked it again. still. not working. the next day i had to go to a trip. so, when i got back, it wasn't working still. so i kicked it, and it worked. ??. but this item was reliable at times, but the connection was loose. so it had issues. but the issues were solved, and it was an amazing product. hope i helped. :) 4 stars
