does this panel step down the voltage for the USB ports, or do i need another product to drop the voltage from 12v?

I have mine hooked straight to the battery through a fuse. The USB ports work for my phones and other electronic devices without any additional equipment.

12v is the voltage used for the USB charging system. It limits the Amperage to that needed.

I don't think you can without something to step down the voltage on the lamp (or whatever product you are using). The product details states that it supports 120 volts.

No. This is not a voltage converter, it is plug / pin converter, it only converts from one pin style to another pin style, no voltage conversion.

Naveen, i could see only one place on the device written as 12V and 1A. voltage value mentioned by your are not mentioned there. hope this helps!

Yes. You should remove power. Follow Abbot F. answer for the steps. Some people answering are saying that "if you are careful" or the power is low voltage and won't hurt you. This isn't the main reason for removing the power. It is in your best interest to protect the new device installing, and also the panel you are connecting it to by removing the power before installing.

Mine included a common US AC 12V 2A power adapter. Then you have standard input connectors for HDMI, VGA, and RCA (yellow). When using HDMI, I had the best results with updating the config.txt file: sudo nano /boot/config.txt #increase HDMI signal strength (just a black screen if not set!) config_hdmi_boost=4 #remove black borders disable_overscan=1 #set specific CVT mode hdmi_cvt 800 480 60 6 0 0 0 #set CVT as default hdmi_group=2 hdmi_mode=87

I only have it plugged into the wall elec. outlet. I don't think its for 12 volt.

This plugs directly into the wall, so it won't work on 12 volts. It works well but only on 120 volts.

The unit requires 5 volts . Therefore , you must use a plug in that reduces the voltage from 12 volt to 5 volt . The one they send with the unit does that . I am quite pleased with my unit .

I use a multi voltage adapter from Wal-Mart. It works great. Just have to make sure to correctly set the voltage and plug the correct adapter onto the connecting lead. The adapter sells for around $14.00 and can be bought with or without a USB socket.

I looked at the back and the power supply. There is a little red switch which allows one to swap between higher and lower voltage. I don't know if this helps and if this is a standard feature. I bought this because it was a good deal.

You can hook up +5v to +12v to the VCC pin if you have an external DC power source, otherwise you need to use the USB.

My voltage requirements were different than the spec, so it didn't end up working for me with my raspberry pi

Do you mean the voltage output? If so, it outputs USB voltage (5 V DC at a max of 2 amps).

You can buy a step down voltage reduction on the internet from the eastern states. Ian L

You won't want to connect the panel directly to a battery, as it could damage or overcharge it. The panel itself only provides a voltage, you need a charge controller between the panel and the battery. The one I used (http://www.amazon.com/gp/product/B001HWQZNQ/ref=wms_ohs_product?ie=UTF8&psc;=1) is not currently available, but should give you an idea of what to look for. You want a controller that can handle at least 30 watts and 17.5 volts input for charging 12v batteries.

I am not sure what is meant by 5v, but I installed it into an ancient Pentium board that is running Windows XP that had USB 1.1 ports with no problems because I needed two USB 2.0 ports.
