A: Judge based on the industry average level. Current industry average conversion efficiency of solar panel ranges from 15% to 17%. And the surface solar energy is 1000W/m². Here we can do the math: Electrical energy converted from solar energy per square meter: 1000W/m²x15%=150W Electrical energy converted from solar energy per square centimeter: 150W/10000=0.015W How much electrical power can you get in 10cm²? 0.015W x10=0.15W

By Karl I bought this panel to charge my Nokia N810 on a week-long camping trip. I was able to charge my N810 (PDA,) my old HTC Wallaby smartphone, and my girlfriend's Sansa e260 music player with it. I never let any of them run down to 0% battery, however it took the HTC Wallaby only about 4 hours total to charge both the internal and external batteries from about 5% total battery power. The Sansa took two hours to charge to full from 25%, and the N810 charged from 50% to full in around 2 hours. The panel is listed as a max 410mA, and in full sun, properly angled, I was reading 400mA from the panel. The biggest point of note is that in order to get full power from any solar panel, it needs to face the sun directly. This means in order to get the most out of the panel you need to readjust the angle every hour or so. The way I judge the proper angle of the panel was to put a one inch bolt through the small grommet at the bottom of the panel. With the bolt firmly in place, I turn and tilt the panel until the bolt has no shadow - this then means that the bolt, and therefore the panel, is aimed directly at the sun. Charging in the car works, but with similar concerns. It's much more difficult to properly orient the panel, and driving around results in inconsistent light hitting the panel, resulting in longer charge times. The panel came with an assortment of charging plugs, however none fit the HTC Wallaby, so I needed to make my own. It did have the 2mm charger for most Nokia devices (my N810 included) and the power connector on the panel itself is a USB socket, allowing most USB charging cords to be used. The panel worked beautifully for me, and even with 3 different devices I was able to keep all three charged for the entire week I was camping. I was using the N810 for roughly 5 hours a day, the HTC Wallaby for about 3 hours at night watching movies, and the Sansa e260 was running 8+ hours a day. I highly recommend this solar panel if you have any mobile devices you might need to keep charged while camping or hiking. It's small, light and provides enough power to charge many handheld devices. For this price, I have found it more than worth the money. 1 of 1 people found the following review helpful. Packs a good wallop By RickaTTic This is a very nice product and has a good output as advertised. I measured 5.10 volts open and 400ma short circuit with a VOM. Charging my LG900 phones takes about 4 hours from almost dead in good sunlight. I really like the fact of how the panel produces good output across 180 degrees of sun orientation. Moving the panel to track the sun is not really necessary so you can set it and forget it. I bought a USB charger cable which plugged right into the panel and phone for $3 from a 'dollar store'. The unit comes with an assortment of plugs for cellphones and the radio shack style adaptaplug connectors. I gutted one of the included cellphone plugs (A BIGFAT OLD STYLE)and soldered together a 2 pin female adaptaplug so I could have a neg 5 volt plug in center pin for my Kaito SW radio. It plays and charges that thing perfectly. Since an adaptaplug female cable is not included you will have to rig up a connector if you want to reverse polarities from the included set which gives +plus voltage to the center pins. My plan was to run and charge my Kaito KA1102 AM/FM/HF radio (-NEG 5 VOLT CENTER PIN)during power failures. These panels are really nice and seem quite durable and easily run the radio and charger. 0 of 0 people found the following review helpful. Not a practical phone charger for hiking in the east. By jonpay Tried this charger for two weeks while hiking. The device would work when facing the sun directly during the middle of the day but even a slight shadow from a limb would cause it to discharge rather than charge the phone. It may work well in the west but is
