It was a sunny afternoon / evening with few clouds , with sun shining until 7.:30 when it went behind a tree on its way to sunset.
The phone was on when I removed it from the charger at 8:00 , it must of came on by itself after reaching 100% charge. The battery indicator read 100% reached somewhere in the allotted time. It was charging from 3:00 to 8:00 or 5 hours , not bad for its first test. Next test will be under full cloud The final test will be under full sun on a cloudless day and timed for its duration to 100% charge , from 20%. Leaving me somewhat impressed |

I can use simple math to get the charge rate of the panel by comparing its charge time to the wall chargers charge time and mA output rating.
~ Normal charge durations ~ From a completely dead battery to 100% takes about 4 hours via USB charging. Using the wall adapter takes roughly 3 hours. From the 20% warning alert to 100% takes about 2 hours via USB. The battery will "fast charge" to 80% pretty quick and then "trickle charge" slowly the remaining 20%. from this link on apples site: https://discussions.apple.com/thread/3453933 Last edited by ecomodded; 06-21-14 at 11:36 PM.. |

I tested the amperage and voltage of the panel this afternoon at 12:30. high noon
Amperage) 2.850 A Voltage) 4.985V which is 14.20w All these measurements were taking using the GREENLEE dm-810 true rms multimeter. This Panel seems to be the real deal, further testing will be done when the phone needs a charge and time permits. ( I edited post #1 to clarify the PV folder's output is 7w per side not total , as was determined today ) Last edited by ecomodded; 06-23-14 at 01:04 AM.. |

I am surprised myself
I had thought it was only 7w total, each panel had a 7w sticker on it , I assumed that it was for both panels and not each , but they advertised it correctly , 7w per panel. I feel like China deserves some credit for this one - It is a powerful little sucker |

I gave the iphone another charge from its 20% charge state.
It was in full sun at high noon when I started the charge but this time I put it in Airplane mode and left it on so I could keep tabs on it easily. I checked the phone for its charge after 2hrs 5 minutes and the phone was at 99% , I checked again 15 minutes later and it was at 100%. It took 2hr 15min from 20% to 100% with the panel left in one position leaning against a railing on the front deck. Should work good to charge my GPS in he field as now I have only 6hrs of use before the charge runs out. |
