Q1: How much faster is this 3A charger compared to my original 2A charger?
A: A 3A charger delivers 50% more current per hour than a standard 2A unit. For example, if you have a 13Ah battery on your Engwe L20, a standard 2A charger will take over 6.5 hours from empty. This upgraded 3A charger will fill that same battery in approximately 4.5 hours.
Q2: How do I know when the battery is completely finished charging?
A: The charger features a simple LED indicator light on the top.
Q3: Is it safe to leave this charger plugged into my bike overnight?
A: While the charger features a smart auto-shutoff mechanism that stops power delivery once the battery is full (turning the light green), it is generally best practice for lithium-ion safety and battery longevity to unplug the charger from the wall and the bike within a few hours of reaching a full charge.
