IP65 1.5A USB to 12V Smart Battery Charger Automotive Maintainer

This compact USB-to-12V smart battery charger is designed for automotive, motorcycle and small lead-acid batteries, delivering reliable and safe maintenance charging with intelligent control.

Featuring a wide 5V-9V USB input and a stable 12V 1.5A output, it supports three core working stages: low-voltage battery activation (3V-8V), fast charging (8V-15V) and automatic stop charging (above 15V). It automatically initiates charging when the battery voltage drops below 13V, providing hands-free operation.

Built with comprehensive safety protections, including reverse polarity, short circuit and overcharge protection, it prevents damage to the battery and the device. LED indicator lights clearly show charging status (slow-flashing green for normal charging, steady green for full charge, steady red for errors), while the 180cm long cable offers flexible installation in different scenarios
