In full sunlight, how long to charge an iPhone from completely drained to 100% (7w model)? How long does it take to charge a 10,000 mah battery?

No idea. It was very slow charging my kindle tablet. I finally gave up and charged it indoors.

The seller lists the optimal power outputs at "5W puts out ~1A the 7W ~1.4A and the 10W ~2A" So that should mean that a 10,000 mAh (10 amp) battery should charge in ABOUT 7.14 hours (7h 8m) in full sunlight using the 7W version.

It can take about 2-3 hours in full sunlight. Shouldn't be more then 2 but give it some leeway

David, I can only speak for charging my Nokia Lumia 900 Windows Phone (currently running v7.8). Fully opened, exposing all four solar panels across the dashboard below the windshield, my Nokia 900 detected a charging source - the portable solar charger - within seconds, and within 5 minutes increased the charge from 78% to 81%. I don't think there is enough total solar capacity, from this particular size solar charger, to fully charge my Nokia 900 to 100%, but it should charge it to above 90% within a few hours (with good sun exposure). For my use, recharging my phone while driving in my car, or when hiking with my backpack, this portable solar charger meets my needs. I have used it three times to recharge my Nokia, during my hour-long commute back home, from just under 50% charge to just over 70% charge. I hope that helps.

If you fully charge the solar charger with a USB port Ajax of time the battery works great. It will fully a dead iphone 5 battery in a couple of hours. The battery will stop have enough reserve to recharge a second iPhone 5 to about 80%. The battery is great. The problem I had was with the solar panel. The panel will not recharge the battery.

A long time! I've never quite accomplished this because my Allpowers 7 watt quits charging my iPhone5 phone (using an Apple charger) after a few minutes. I receive that annoying error message ""This accessory is not made to work with iPhone" and it stops charging my phone!!

Fully drained to fully charged is about seven hours, but it may depend on the charger

You'll need a 24V solar charge controller, hooked up to the solar panel and then to your battery. In full sun, it will take about 20 hours to fully charge a 100 AH battery. However, you should not let your battery get much less than 50 percent of capacity between charges.

'cause when the phone says 100% the battery is not actually there. the phone only interprets the voltage it senses but the capacity of battery is not full yet. I recommend to only charge the phone with at least 2A charger. suppose you have a 0.7 Ah charger (700mA) (it reads on the charger btw) then 10000mA divided by 700 means 14 hours of charge required! this is why you should always charge with 2A charger, that way over night (cca 6h) your phone will be fully charged.

It took about 9 hours, which is not far from what they claim in the manual: 6-8 hours on USB.Charging an Acer A110 Tablet afterwards to a full charge took about 4 hours and emptied battery for about a half. Nevertheless, it was enough to charge Droid Incredible 4G to a full charge as well. Using solar charge is another story. It does not seem to like anything else that direct sunlight and by "direct" I mean literally pointed perpendicular to a sun rays. Also, manual says it needs 11 hours of sunlight to be fully charged, so I bet it would never happen. Otherwise, very handy device.

I got this to charge my iphone. I put a pair of fresh batteries in and it charged it for about 30 mins. and i can't charge the batteries it came with because the plug is not made for the US. my advice is to look for a power bank, or if you want to look for something that will be effective if the power goes out for a longer time a solar charger. there are a few under $20 just search "solar charger usb" and make sure it says power bank or external battery as well

It took about 5 hours to go from nearly dead to completely charged. I was able to run my iPad for an additional 10 hours without bringing it back to completely dead. I have also completely charged 2 iPhones without completely draining the battery. How much you are able to do will depend on whether you have to use your iPad or phone while it is charging, and whether you attempt to charge from a completely dead state.

Yeah that's sounds about right. it take 10 hours to about fully charge the battery unit with solar. the life of the laptop depends on the laptops power settings and what you are doing with it. I most use this device to charge cell phones and cameras etc...

I tested mine yesterday, It was a 1 bar and it took 3 hours to come to full charge. Hope this help you with a guideline.

It depends on how many amps you charge it with and how drained the cell is. They're rated at 3000mah so at a 3 amp rate it would be charged in 1 hour if it were completely drained. But the cells don't live up to there 3000mah rating and you should never completely drain it.

I'm not quite sue--I've never used it long enough to drain a charge. My guess would be several hours. Sorry I can't be more helpful.

Depends on what you're charging. My anecdotal evidence would shows that I can charge my note 3 (3100mAh) and lose a bar (there are 4) which at 2A, takes about an hour or so to full charge. I usually only lose a bar when I have my iphone and note 3 hooked up (both are not fully drained tho) At 12A-H, a 2A load would take about 6 hours to drain the battery. I have to look up how to actually calculate the draw down time when at max load (3.1A) and do some more conclusively testing (like timing it). Hope this can provide some guidance.

For new batteries always do a complete drain. To accomplish this, turn off power management on the phone, disable screen dimming and any other power saving feature. Leave the phone on until the phone turns off on it's own. Battery should be fully drained at that point. Connect to wall outlet charger - do not use USB port on computer. Charging should only take 3 - 3.5 hours at most. The phone should show 100% capacity. If it doesn't then repeat the process for a 2nd time. If after second full drain and charge the battery still doesn't show 100% charge then you may have an issue with the battery at which time contact the manufacturer for replacement.

Not sure, but I can completely charge my iPhone within a couple of hours when the battery is very low.
