If only the sun had a USB port.....
dailysteals listing. expired... That's a good thing.
Too much bad feedback to deal with these jokers.
Meritline and these guys must be buying from the same Chinese shop.
Check the specs on this item. Under ideal conditions it would take days to charge using the sun unless you live where the sun shines 24 hours a day. Under normal conditions it would just about make up for the self discharge rate of the batteries. Using the usb charging method would take half a day or more even if battery charging was 100% efficient, which it isn't.
This should be called a solar battery maintainer. Move on along, not a tree to hug anywhere near this.
Assuming you are not opening it up and trying to use it right away, this is for those who are going to be out there without an outlet or charging station. I can see this being charged up BEFORE use. Then used to keep a cellphone or gps charged while camping away from the car.
Stick this where the sun don't shine.
this is good for brownouts.solar charger is no need sockets, charge it by putting it on the top of your table,if you say solar it doesn't mean that you really put it under the sun.you can put it anywhere you like that possible to light.
enjoy charging even brownouts...

I doubt either of them had any say over where Kodak had them made... but yeah, prob made in China or nearby like most consumer electronics these days.
Not sure where #3 gets the info for USB charge period. USB's 5V/500mA capability would mean a purely resistive charge method putting 500mA into the cells would take a little under 5 hours. IF it has a switching converter it's faster...
USB 5V * 0.5A = 2.5W input
2 cells * 1.2V nominal * 2100mAH = 5W
Figure about 75% efficiency from the converter and charging losses and that's 2.7 hours. I doubt it charges that fast, but it could easily do so (would just cost a few bucks more to build it).
# 3 got his info from the item page, hence the part where I said to check the specs on this item.
Power Specifications:
USB: Input: 5.0 V DC, 500 mA, Output: 2.4 V DC, 180 mA
Battery Input: 3 V DC, Output: 2.4 V DC, 0.3A
Solar Input: 4 V DC, 20 - 100 mA, Output: 2.4 V DC, 20 - 90 mA
A 2100 mA battery charged at 180 mA = 11.6 hours. With a little extra because charging any battery is not 100% efficient = more than 12 hours. Just because a USB port is rated at .5 A does not mean every device makes full use of that, and this charger doesn't.
Just trying to point out that this is not what most would consider a battery charger even when connected to a USB port, and certainly not used as a solar charger. Note it is rated at 20 - 90mA? 90 would be a maximum, like direct full sunlight hitting the panel straight on. Imagine what the real output is when it is used in the real world with the sun at an angle and the sky a little hazy. Now multiply maybe 50mA average (if we are lucky) by the number of decent usable sunny hours and lets call that 10 hours. 10 X 50mA = 500mA, so it would take 4.2 days to charge the batteries if the charge process had no loss. That still assumes that you had 4.2 days of sunny weather and kept this in a good place. Now factor in that the batteries that come with this are not low self discharge batteries, which will self drain in about a month, so 2100 divided by 30 = around 70mA per day needed just to maintain the charge. So in the real world, don't be surprised if it takes a week or more to charge these two 2100mA batteries. Now if the output of this thing is 5 Volt, you will also have efficiency loss as it converts the 2.4 volts up to 5 Volts, so you will get much less than 2100mA of usable power to charge your phone. I would call this more of a battery maintainer, but hey it's not my money in your pocket.
Well, you could modify it so the full 500mA were charging the batteries. Think I probably would since that 180mA rate is too low for a Delta -V charge termination feature meaning it's just a *dumb* charging circuit.
There's no way the solar cell will average 50mA/H for 10 hours every day unless you used mirrors and re-aimed it at the sun every so often.
So if you bought this and modified it, it would still make a poor battery charger since it would not have a proper cut off, plus you don't think it would work as well as I said it would as a solar charger? Note the part where I said 50mA would be if we were lucky.
I'm saying IF I had one, I could make it work better... You can get charging ICs that would cut it off when fully charged, they'll work with a 500mA rate BUT I see no reason to pay more for the solar cell if that's the goal.
What I'd do instead? Buy a 4 pack of Eneloops.
