Two USB outputs allow charging of two phones or devices at once, keeping you and your family connected and contactable. Simple plug-and-play installation does not require an electrician or trained service person. All necessary components are included for a fast, neat and easy installation. Larger batteries and panels up to a total of 60W can be added to the system. The High tech controller extends the life of your battery and provides constant power through the USB and 12V outputs.
