Bosch Power Tools 12a Quad Charger 14.4v/18v Lithium Battery Adapters Charging Dock Leads With 2*usb 5v/2.1a

Bosch Power Tools 12A Quad Charger 14.4V/18V Lithium Battery adapters charging dock leads with 2*USB 5V/2.1A Why is it expensive ? Package is about 2Kg,too much freight. Input voltage: AC/100V-240V,50/60HZ Output:14.4V/18V,4*3A, 2*USB:5v/2.1A Feature: Full series with single battery detection, temperature control, timing, short circuit protection, battery repair, overheating intelligent charging, magnetic field protection, delay protection, frequency protection, power protection, leakage protection, overcharge protection, overvoltage protection, overcurrent Protection, after the zero voltage detection protocol is powered on, the pulse is executed according to the battery voltage, and the repair is prioritized to protect the battery. Replace the Bosch four-charge independent power supply board. Each controller has a total output current of 3A*4=12A and a single channel of 3A, with a built-in high-power anti-interference power board. Ensure that each channel is independently and safely charged, compatible with Bosch 14.4/18V lithium battery pack. With single battery detection, temperature control, timing, short circuit protection, battery repair, overheating smart charging, magnetic field protection, delay protection, frequency protection, power protection, leakage protection, overcharge protection, overvoltage protection, overcurrent protection, zero voltage After the protocol is detected, the pulse repair is performed according to the battery voltage, which is a new generation charging method that prioritizes the protection of the battery. The six-level energy-efficiency power supply drives the IC, and the single-chip microcomputer adopts the latest packaged 14-nanometer process. It has high integration, good compatibility and stronger anti-interference
