This charge controller is to safe guard and protect the batteries during charging.
Use the controller when charging 12V batteries. You can make use of the crocodile clips.
For a solar generator that has a built-in charger you can use the connectors(MC4's). You can just plug them into the cables and it will be charging.
It is possible to charge a 12V battery and a solar generator simultaneously.
Also the controller has a 5 volts 1.2 Ampere USB port for smaller appliances.
The controller as well as the USB port will not respond before you connect it to the battery.
You can use a 14AWG extension cable before the charge controller if you have to. Acopower is the seller of this cable.
We have to connect the battery, then load and last the 70 watt portable solar module.
When disconnecting it is panel, load, and then battery.

With attached wires and the stands it is easy and very quick to set up...
Go to a sunny area, without obstacles to block the sun.
Unfold the panels. Face the sun and it will start producing a power output.
Adjust the solar panel to get maximum sunlight during the whole day for most power output. For proper direction use the kickstands.
Read the safety instructions before putting the 70 watt foldable solar panel kit into operation.
See that battery clip connection is done properly. This is to avoid any short circuits.
Remember obstacles that cover the surface of the 70 watt solar panel kit reduce output.
Dust and dirt can some times cover the surface of solar
panels. Remove it, it can decrease efficiency.
Now you can clean using a soft brush. Remove the remaining dust and dirt with a damp cloth.
It is good to have a USB charge port, but it will only work when you connect to a battery.
Some people suggest Acopower to change the LED color from blue to red. Seeing the lights will be so much easier then, no matter how bright it is outside.
The solar panel itself comes with an 18-months workmanship warranty. As well as a 25-year 85% output warranty.
The controller comes with a 1-year warranty.
The 70 watt solar panel kit is flexible. You can use it with a variety of devices.
It is well built and a definite plus if you are looking for a portable solar panel.
