“This is the "newer" Nami charger. It is very well designed compared to some of the older high-amperage chargers. No sparks at all plugging it in (scooter first, then wall). It has a screw cap to secure the connector to the scooter. Remember to be careful plugging it in so you don't damage the connector or pins. It does have a small bit of fan noise while charging, but that helps it maintain cooler temperatures and prolong its life. This newer charger has a high-quality charging circuit which I think adds significant safety over other designs.”
