Will this item charge a device using only the solar cell? I've found this sort of device tends to only power the USB port if the crank is being turned

It does charge based off solar. My radio is fully charged now and will charge my cell. It will drain pretty quick if not kept where it can charge.

I can't tell that it charges from solar at all. It is advertised and sold as 30,000mah but when it was received, it is 10,000mah. It does not chage my phone or my Ipad. I will be returning it. But, to answer your question, I do not know if it charges both ways simultaneously, because the instructions are so poor, in gibberish English.

No, it's direct solar to usb, but you can use any usb rechargeable battery pack you choose.

you can charge via usb port from the solar charger And the battery pack. battery itself is aIt's lithium IOn 5200 mah. the solar panel itself will charge it but I don't know how long it'll take and it's more than just interrupted sunligHt On the Panel It's also The Angle With The Sun As With solar panels

You would have to crank it to provide power to the USB, but the flashlight on the device already provide light. It doesn't operate as a battery pack would. The cranking operation charges the battery to the flashlight and also outgoing power to the USB during the cranking. The flashlight works on its own without cranking, but the USB does not. Hope that makes sense.

The plug-in charger only puts out 2 amps. If your solar panel USB port has similar output there should not be a problem.

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 have only had to use it a few times so far, but even out of the sun it appears to charge as long as the power cell has some juice stored in it. I would suggest contacting the manufacturer to be sure, especially if you really need to rely on it for a longer trip.

Remember, this is a 4 amp unit. That means that any single device which needs less than 4A to charge, will be charged.... as long as that is the only device attached. If you have other devices attached, they will be drawing some current, usually up to 900 mA for a USB3 device... sooo something like an iPad may not be able to draw enough current. Most other devices should be ok.

Nope !! I've tried that ! Lol. It only charges the battery and the USB whole plug in . If you want that capability you might as well buy a portable charger. I've boughten 2x 12$ from Amazon already. Great stuff.

That means no battery power unless you crank the device.if you use the solar and it runs down you crank it. Great light.minuse mine all the time.

I either charge by plug hinging into computer uSB or plugging into my iPhone wall charger. Do no know about solar. If it has USB I would think it would work or 110 female plug

I have seen it done and tested it. You need to get one of those 12V to USB converters to protect your device. Contact us to discuss. rich j itc solar

It only charges through the power adapter provided. The USB port is data only & does not support the power functionality of USB.

No, sorry. This will only charge devices that are USB-powered such as smartphones, electronic book readers, tablets, etc.

I don't know. I checked the list of things it was said to charge before I bought it to make sure it was compatible. I've bought one in the past that I had to return because my devices weren't supported. I've found, The less computerized something is, the more likely it is to be usable with a solar charger.

It is designed to charge batteries. Adding a battery would be redundant. the devices with small solar panels and hand cranks don't really work. The hand crank and solar cell are too small to do anything. If you buy one the instructions say plug it into a wall outlet. This is actually designed to be used as a hand crank. Puts out enough power to be practical. You do have to crank and it takes a little practice to establish a rhythm but you can charge a phone anywhere any time. the ultimate backup. Always works. Ken
