how much power does it draw when being charged

Hard to say for sure, but the charger/adapter output is less than 1 amp. (975 ma) combined for both supply voltages.

Hard to say exactly because it depends on the intensity of the sun. I charged up mine totally in two full sun days.

Ansgar - I am sorry but I don't really know. When it arrived it was nearly fully charged. Since then I have usually just plugged it in every once in a while. I'll try to really run it down and they take note and try to pass the info on. Sorry I could not have been of more help.----M

The literature indicates up to 7 hours. I havn't used it for that long so I can't confirm this. I did use it for several hours after charging it for the first time and it still had enough power for a few hours more use a few weeks later before I needed to charge it again.

I can't answer your question now. But I do have a device that you plug things into and it tells you how much electricity it is drawing. I can try the charger with or without devices charging and let you know. But I really do like the charger and it has simplified our lives. When my wife understands how to use it, I know it is good!

Really I don't know. I usually charge it around 8 hours and after that, I use it. But I don't like at all.

I don't know exactly but it's charged my phone from 40% up to 90% in a very short amount of time

Short answer: 0.08 - 0.10 watts. I measured it with a Kill A Watt Model P4400 while charging a Kindle.

Not sure. I let it charge over night but am not sure if it takes that long to really charge it. Sorry

I haven't gotten a chance to use it yet but figure it this way ... If you have a newish Samsung device or IDevice and it charges it should be at least 1 amp. If it fully charges a device like the Samsung 4 its probably 2 amps. I was slightly peeved when I got this and it didn't have the normal conversion sticker like other solar usb devices. We both have to hope we didn't buy an 8800 maH battery that doesn't charge anything in the 21st century.

Not completely positive, but more than six to eight hours. I find it is not a quick charge at any given time, but your given adequate warning that it needs a charge and can plug it in overnight so it's ready when you do need it.

Just a further follow-up, it charged my iPhone from approx.15% to over 90% in about an hour. Hope this info is helpful.

I did not notice any indication however, I charge it usually about 2 1/2 hours and I can use it to charge my cell phone at least 2 times, before having to recharge it again. The red light only indicated when you are charging your phone off of it. I have used it several times when the power in the house went off due to storms and when I was out and forgot to charge my phone before leaving home. I found it very useful to have.

I'm not sure if it even charges to a full charge when runs out ,but it's enough to get you through the rest of the day ,so the answer is 1 charge .it will need to be recharged after the 1 charge .,but I like it

I am not sure, but I had it running for about 2.5 hours straight. Then, I did recharge it when I got home, but it did not take long to charge.

I use mine in my boat and when I'm not at the dock it runs on an inverter. Don't know the specific power draw but I have a big 4D battery and it lasts somewhere around 30 hours if I don't recharge.

Have no idea. Likely 10w..??? It takes same amount of time to charge my iphone and ipad compared to a regular plug
