Okay, important note right up front - this charger is for Razor Power Core models like the E90, E95, MX125 Dirt Bike, and similar, but it does NOT fit the regular Razor E90 scooter! The connector size is different, so double-check what model you have before buying. This is a 12V 1A power adapter that works with input from 100-240V AC, so you can use it pretty much anywhere. The cord is about 6.6 feet (2 meters) long, which gives you some flexibility in where you plug it in. It's compatible with a bunch of Razor Power Core models as well as various 12V kids ride-on cars from brands like Dynacraft, Kid Trax, and others. The charger has a handy indicator light system - red means it's charging, green means the battery is full and ready to go. This helps protect your battery's lifespan by preventing overcharging. Perfect for keeping your kid's electric scooter or ride-on car powered up and ready for action. The build quality feels solid - not one of those flimsy chargers that breaks after a few uses. Just make absolutely sure you're getting the right connector for your specific model, because Razor uses different plugs for different products. If you accidentally order the wrong one, most sellers are good about exchanges, but it's better to get it right the first time. Much cheaper than buying a replacement directly from Razor, and works just as well for keeping your electric toys running.
