【Smart Battery & USB Charger】 This 2-way charger can be used as a USB power source while driving and as a battery charger when parked. The mode switches automatically when the key is turned ON/OFF. It supplies power to the vehicle's battery via its USB-C port, allowing for easy battery charging even in environments without power outlets. Compatible with DC12V lead-acid batteries and lithium-ion batteries, it can be used for a wide range of applications. Unlike conventional 100V AC power supplies, it uses USB power for charging. Because it can be powered by portable batteries or mobile batteries, battery charging is possible even in parking lots without power outlets. When the key is ON, it functions as a USB power source for fast charging of smartphones, PCs, etc.
【Caution】 ■Some mobile batteries have a power consumption reduction function that automatically shuts off the power after battery charging is complete, potentially preventing maintenance charging. In such cases, continuous operation may be possible by using a loop circuit (a method where one of the two USB ports on a mobile battery is returned to the mobile battery's input). This function remains ON when the mobile battery is charging or outputting via USB. Please consult the mobile battery manufacturer regarding the presence of this function. ■The USB power supply connected when charging the vehicle battery operates with 9V, 12V, 15V, and 20V outputs. (It will not operate with a 5V output.)
■When connecting a device that operates with a Type-C power supply, it may not function properly due to compatibility issues with this unit's vehicle battery charging function.
■This product has a maintenance charging function, so even after the vehicle battery is fully charged, it will continue to consume a small amount of power to maintain its condition. Most mobile batteries have an over-discharge protection function to prevent voltage drops below a certain level to protect the lithium-ion battery. However, some mobile batteries are designed to rely on the charging control of the connected device, such as a smartphone, and may not have sufficient or any over-discharge protection function built into the mobile battery itself. If such a mobile battery is connected to this product, the maintenance charging function will continue to consume power, causing the mobile battery to over-discharge, and it may not recover even after charging, rendering it unusable. When using this product with a mobile battery, please check that your mobile battery has an over-discharge protection function before considering use. Please note that since the mobile battery is not our product, we cannot provide information regarding compatibility or guarantee of operation.
[Easy and convenient use in any environment] High-efficiency automatic optimized charging. With a maximum output of 5.5A (※limited by input power), it automatically optimizes charging until the battery is fully charged, efficiently charging while preventing battery degradation. Even after charging is complete, it is equipped with a maintenance charging function that automatically starts recharging when a voltage drop is detected. It keeps the battery in optimal condition even when the charger is left connected. Since it is installed in the vehicle as a USB power source, there is no need to set up a separate charger to charge the battery. It is useful in environments without power outlets, such as parking lots and outdoors. This 2-way charger is a product that allows you to complete both fast charging of devices and charging of the vehicle battery with a single unit by installing it in the vehicle. It is ideal for those who value convenience and practicality.
[Details of vehicle battery charging function] ◾️When charging the vehicle battery, the output power will vary depending on the input power. We recommend using a USB cable that supports USB output. When using a USB Type-A power supply (will not work with a 5V USB power supply): Input 9V 2A (USB-C side), Output 13.0V 1.3A (vehicle battery side) Input 12V 1.5A (USB-C side), Output 13.0V 1.3A (vehicle battery side) When using a USB Type-C power supply: Input 15V 2.5A (USB-C side), Output 13.0V 2A (vehicle battery side) Input 20V 1.5A (USB-C side), Output 13.0V 2.2A (vehicle battery side) Input 20V 5A (USB-C side), Output 13.0V 5.5A (vehicle battery side)
