TK20U 10A 20A 12V24V auto work




  • Vivid LED indicators show system battery capacity, charging and discharging state of battery.
  • Protection functions such as overcharging, over discharging, overload and reverse connection. 
  • PWM charging increases charging efficiency by 3% to 6%, compared with non-PWM charging. 
  • The parameters of charging and discharging are preset, so no need to adjust the parameters. (Special parameters need to be advised in advance.) 
  • USB output function.
