For anyone wondering about VPOR's whiz board battery/charger specifications, I called VPOR today and spoke with their secretary. I specifically asked if both the charger and battery had the UL symbol on each part, and she replied yes they do. I also asked if she could give me the numbers written beside the UL symbol, but she wasn't quite sure at the moment. She ensured that the batteries/chargers they use aren't cheap.
She then proceeded to tell me that VPOR hasn't had a single customer issue from the whiz board in the 7 months they've been selling them. She stated that each board comes with a 1 year warranty.
I also addressed the current Amazon situation with hover boards. I told the secretary that Amazon is now bringing a select few of hover board brands back to their market, and she stated they're working on getting their boards back up as well.
Hope this helps,
