Before I return mine, one does it not charge by solar power. It charges by the cord but 3 days in the bright sun and nothing.

Mine never gets fully charged through solar but electrical power. It stays at 25% all the time even after 2 days. Your best bet is to use Alternate Current to charge your YCPower. You get 25% of charge every one hour. Regrettably, I had to return mine for an exchange, because the flash light stops working.

I have not had the chance to use solar charging yet but everything else works great!

Yes charges by cord. The solar panel output is about 15v claimed. But I have tried more than half day and nohing happened.

Are you getting the red flashing light indicating it's solar charging? Since it sounds like you have a problem, you should contact the company? I would do that immediately and see what they say.

Hi Mark, Ycpower charges well from mains (power cord). You actually see the battery level increasing to the maximum (100%) within a very short time. But by solar, the charge rate is incredibly low. I don't recall if the battery power has ever risen above 20% on solar charge. It appears solar charging is not effective.

First one I had worked for about 3 years. The second one is still working after a year. If you just got it and you have it in the sun, it should work. I would send it back.

No. This only charges while it is exposed to direct sunlight. It also does not hold a charge if nothing is plugged into the USB port.

Hi there - yes to both. If you plug it into a computer it will charge a little faster than if you place it in sunlight. You'll need to give it at least 12 hours of constant charge at first...

I think the instruction said something about how the solar charger will not charge the battery, just allow you to use it while it was shining. You might check online for the instruction Manual.

Have a goal zero 13, when the sun is out it charges just fine. Will take a couple of days to figure out the charge rate. Charged 6 hours today got to 50% , 16 hours to full charge

charge it as many times as you want by the sun depends on how much sun you get it takes about 3 days for 100 percent. to help get to 100 % you can charge it by a lamp or any light.

I agree with everyone, I allowed it to charge for 2 -3 days in the sunlight before using, then waited till dark and gently pushed the pin. Mine works great - I have only had one occasion with several rainy days in a row that it did not work -- I just took it inside turned it off and let it recharge in a sunny window - turned it back on and it has worked flawlessly ever since.

Make sure it is seated properly and the power cord is in a functioning outlet. Mine charged immediately and works fine. If that doesn't help, I would return it and request another.

maybe, check all of your connections, we did need to let ours charge in bright light/sun for a while before it started

I am glad your pump works as mine has not since the first few months.i fussed around with it, and it only charged for a few minutes. We have lots of sun here, so this is not a problem. I gave up and ordered a different type of pump that I can charge any time and take any where.

Must be defective in some way. I would send it back. I haven't had any problems charging mine. It charges fully and I am able to use it without it being plugged in for at least a few hours.

I've read that these sometimes have a break-in period and that the charging indication corrects itself after a few days of use. I'd try charging it up and using it and recharging it a few times to see if that helps. Only "problem" is that the charge lasts a long long time! Good luck.

For me when the device was fully charged, it charged my phone once 100%. If you will be able to chage it again using solar power then, it will work again and again. I had trouble getting mine to change using solar energy because i guess i didn't find the right angle. My suggestion would be get one that you know will for sure be able to charge by using solar energy. Hope this helps and good luck !

It just so happens that I bought the same item. I left it connected to my Solar panel 12v I then set the whole unit in the window to catch the rays of the Sun. I must admit though I had forgotten it till the next day at the same time. When I looked the lights were lit. I tried it a second time and the lights were lit again. Give it a try. Hope this helps you.

No...It has to be direct sunlight. Also, the solar charger takes a long time to recharge the battery. I basically just used it as a secondary battery and charged it from the wall socket the night before. I think the solar charger would only help if you had several days to charge it. I left it on my dash once for a week and it barely charged half way.

That's a good question. I THINK it works by either charging the connected device from its battery, or by charging the battery. There's an on/off switch that powers the USB connection. So that's a way to differentiate this from a true solar charger. With this you can charge and store, with a solar charger you have to leave the device connected to the solar charger and in the sun to charge. I could be wrong about that. I may ahve to test that the next sunny day.
