Kaedear Motorcycle 12V Battery Charger, USB Input, 2A Maintenance Charger, KDR-B12

【Smart Battery Charger】 USB Input Battery Charger This USB input battery charger allows for easy battery charging even in environments without power outlets. It supports DC12V lead-acid batteries and lithium-ion batteries, making it suitable for a wide range of applications. USB Power Charging Unlike conventional 100V AC power supplies, this charger uses USB power. Because it can be powered by portable batteries and mobile batteries, battery charging is possible even in parking lots without power outlets. *Not compatible with idle-stop compatible EFB batteries, lithium batteries other than those for motorcycles and cars, and gel batteries (liquid-free batteries). *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 of returning one of the two USB ports to the mobile battery's input). This function keeps the power ON when the mobile battery is charging or outputting via USB. Please consult the mobile battery manufacturer regarding the presence of this function.

[Easy to use and convenient in any environment] High-efficiency automatic optimized charging With a maximum output of 2A (*limited by input power), it automatically optimizes charging until the battery is fully charged, efficiently charging while preventing battery degradation. Maintenance charging function Even after charging is complete, it is equipped with a maintenance mode that automatically starts recharging when a voltage drop is detected. Maintenance charging will be performed by keeping the charger connected even after full charge. (Maintenance charging cannot be used with power sources that have a function to automatically turn off the power when in standby mode for a long time, such as mobile batteries.) When not charging the battery or performing maintenance charging, please remove the charger from the vehicle. Easy connection with SAE connector Charging can be started by simply plugging in the SAE connector while leaving the wiring in the vehicle body. In addition, it is easy to connect directly to the battery using the included alligator clips. Convenient and wide range of uses With USB input support, it can be charged from portable batteries and mobile batteries. It is useful in environments without power outlets, such as parking lots and outdoors. This USB input battery charger is the perfect product for those who want ease and convenience when charging their batteries. Please use this product in situations where you are using a vehicle or portable power supply.

[Product Details] ◾️This product's output power varies depending on the input power. We recommend using a USB cable that supports USB output. USB Type A: Maximum 18W Input voltage 5V 2.4A, Output current/13.0V 0.6A Input voltage 9V 2A, Output current/13.0V 1A Input voltage 12V 1.5A, Output current/13.0V 1.25A USB Type C: Maximum 30W Input voltage 15V 2.5A, Output current/13.0V 2A Input voltage 20V 1.5A, Output current/13.0V 2A *Please refer to the specifications table in the catalog for details. ◾️Before starting charging, the smart chip checks the battery voltage and condition. It determines the state of over-discharge and the degree of battery degradation, and sets an appropriate charging plan. ◾️In the initial stages of charging, it charges efficiently in constant current mode, and switches to constant voltage mode as the battery voltage rises. This allows for efficient charging while reducing the strain on the battery. ◾️As the battery approaches full charge, the smart chip automatically reduces the charging current. Charging stops when the battery is fully charged, preventing battery degradation due to overcharging. The battery temperature is monitored during charging, and if overheating is detected, the charging current is adjusted or charging is temporarily stopped. This improves safety and extends battery life. ◾️Even if the battery has not been used for a long period or is constantly connected, the smart chip performs appropriate maintenance charging to maintain battery health. ◾️In some cases, the battery may be diagnosed as unchargeable due to degradation, and charging may not be possible.

【Precautions for Use】 ■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. Typical mobile batteries are equipped with over-discharge protection to prevent voltage drops below a certain level in order to protect lithium-ion batteries. However, some mobile batteries are designed to rely on the charging control of the connected device, such as a smartphone, and do not have over-discharge protection, or the over-discharge protection function on the mobile battery itself is insufficient. If such a mobile battery is connected to this product, the maintenance charging function will continue to consume power, causing the mobile battery to enter an over-discharge state, and it may not be able to recover even after charging, rendering it unusable afterward. 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 on compatibility or guarantee of operation. For information on the presence and specifications of protection functions, please check with the seller or manufacturer.
