Rofessional advice from licensed electrician: The max use should be no more than 80% of the full loads. Otherwise, the power supply will generate much heat and its service life will be greatly shortened. Please do not use on constant voltage devices. Make sure and set the correct voltage before connecting your devices. When you turn off the power, because there are precision sensing components on the adapter, the led display will not go off immediately, but will stay on for a while. This is normal and it is not broken. Package: 1x Adjustable Power Adapter(US Plug) 14 x DC adapter Plugs.
