Has anyone tried "piggybacking" a second solar panel through the USB to increase solar efficiency?

I am testing this. And from my last 2 times of charging 2 AAA's. i gotten the charge by using Solar and USB with a RavPower 15watt solar panel. down to about 30-1hour vs 3hours of just the solar charger on the XTG charger itself. I'll message back when i test out 4AA's with this try. But it seems pretty good chaining the integrated Solar panel with a USB high power Solar panel together.

Sure you can but IMO it would take double time as the computer USB should have half the output than the car or electricity net connection.

yes the voltage output will vary with the amount of sunlight. I have my panels setup to produce a max of 36 vdc charging a 12 vdc battery bank. your charge controller needs to match your projected final system capacity, if there is a possibility of adding on later. I have a mix of 144s and 88s

I purchased this after reading the other responses and can confirm. I'm using a single Solarworld 250w panel (24v) with two 6v Sun eXtender batteries (wired for 12v). Works great.

Hi They should work more or less the same. The usb chargers also contain a step down circuit. There are some usb chargers that provide lots of As as well. I use my keedox in a solar power system and it is a bit easier to deal with than messing withtiny usb cable wires. You should test if you usb charger actually provides enough As. Some do not.

never tried, but since it is merely an extension of usb ports, it should work like an electrical extension, whichwhen in use would allow several plugs to run off one outlet.

I was not aware of one and I hooked it up without breaking it.If you have a panel in the sun however, I would think that hooking up the batteries and any accessories first would be the right thing to do, followed by the panels connection

I keep my light in a window to keep it charged, I've never charged with USB, so sorry, I'm not sure. I would assume it would. Mine seems to show the red light only when the solar screen is exposed to light (any kind), showing it's charging.

I connect to 24v batteries rather than solar panels to get max 300w out. The batteries are solar charged.

You certainly can. Think of those big solar arrays...they are several individual panels connected in a system to provide a certain wattage of output.

I think you might possibly be able to connect then together using a usb hub with multiple alternative usb connectors to get a stronger current, unless they have an in-built system to specifically prevent this.

Hi PeterYes, you are quite right. I hadn't tried that but my unit will not do both at the same time. In practice I have a dual USB charger so the need has never arisen. Regards Richard Allan.

Sorry I have not purchased the solar panel but there is a hole in the side of the camera to attach DC power.

No, this panel is only 30 watts, not nearly powerful enough to power one or more of what you had mentioned.

No I would use both solar panels Parallel to each other and use only one controller. Make no sense to use two separate controllers. Un less the panels produce more then 30A each.

no USB connection. it has standard +/- leads. aluminum conductors. you won't find any solar modules with USB as the electrical properties and operation do not align with what a USB connection does. I think what you would be looking for is a charge controller, batteries, and inverter to go with the panel. the inverter is the device that would potentially have a USB connection to power your devices. in short, some sort of power conditioning needs to happen between the solar module and your USB device.

I don't see why that would not work. Although it might take a while to recharge with that solar kit if you are using ac power heavily.
