Frequently Asked Questions
Q: Can this charger handle both AA and AAA 1.5V Li-Ion batteries at the same time?
A: Yes! The 4-slot smart charger supports AA and AAA 1.5V Li-Ion batteries simultaneously. You can mix and match slot by slot — charge two AA and two AAA batteries at the same time if needed.
Q: How do I know when my batteries are fully charged?
A: The built-in LED indicator makes it simple: a red light stays on while the battery is charging, and it switches to a steady green light once the battery is fully charged and the charger has cut power automatically.
Q: What type of cable do I need to power this charger?
A: The charger is powered via a TYPE-C (USB-C) cable, which is included in the box. You can connect it to any standard 5V/2A USB-C power adapter (such as a phone charger or power bank).
Q: Is it safe to leave the charger unattended once batteries are fully charged?
A: The charger features overcharge protection and intelligent circuit management that automatically stops the charging current when batteries reach full capacity, making it safer for everyday use. However, as with all electronic charging devices, it is good practice not to leave it unattended for extended periods.
