Wireless charging box QT-NET620K

Performance characteristics

The designed charging mode is "constant current mode", that is, before the terminal voltage of the battery is replaced by the preset value, the charging is constant current charging; when the terminal voltage of the battery is higher than the preset value, the charging current gradually decreases with the increase of the battery voltage. Fast working efficiency, better battery protection

Perfect protection function: no charging, no current, greatly reducing the invalid heating of battery charging

Metal painting process cabinet, easy to arrange and operate

The charger has 49 channels of output, which can simultaneously provide 49 conference microphones with lithium battery with conventional charging, supplementary charging and equalizing charging needs
