Electric scooter and hoverboard owners, this universal 42V charger is your solution for keeping your ride powered up! Compatible with most 36V lithium battery systems, this smart charger delivers up to 2A for faster charging times. The 3-in-1 connector system includes 5.5mm barrel, mini 3-prong 8mm, and Ninebot/Xiaomi compatible connectors - it works with Phantomgogo, VOLPAM, Gotrax, Jetson, Hiboy, Hover-1, Segway Ninebot, Aovopro, and many more brands. The LED indicators make charging simple - red light means charging in progress, green light means fully charged. The 8.5-foot cord gives you plenty of reach, and the built-in safety protections (OVP, OCP, overload, short-circuit) ensure safe charging every time. Important note - this is ONLY for 36V/37V lithium battery systems, NOT for lead-acid batteries or 24V/48V devices. Always charge one battery at a time, and monitor temperature during the first use. The quality construction is noticeable right away - this isn't some cheap knockoff that might damage your expensive electric vehicle.
