Hi there,
Thank you for sharing your feedback! You’re spot on. It’s completely normal for e-bike chargers to get warm or hot during a charge cycle. Keeping the charger in a well-ventilated area, on a flat hard surface, or resting on its side so air can circulate underneath is a great way to keep temperatures down. If you ever feel the charger is becoming excessively hot to the touch, please don't hesitate to reach out to our support team so we can take a closer look!
Regards,
Aventon
