The four solar cells were about 6.5 inches by 1 7/8 inches each for a calculated total of 48.75 square inches. A square meter is a little under 40 inches by 40 inches. One percent of it is a little under 4 inches by 4 inches or 16 square inches. 48.75 divided by 16 is a bit more than 3. The standard light power for solar cells is the AM 1.5 global solar spectrum sunlight standard = 1,000.4 Watts per square meter. One percent is about 10 Watts and three percent is about 30 Watts so the 30 Watts in the description is the total input wattage at the AM 1.5 standard. 25% efficiency would yield 7.5 Watts, 20% efficiency would yield 6 Watts and 15% efficiency would yield about 4.5 Watts for conversion of solar energy to electrical energy. Those Watts would be converted to a usable voltage and current for a load such as a cellphone. The conversion is not particularly efficient due to the low voltages coming from individual solar cells. Conversion in large solar panels is much more efficient but those cost a lot more. My testing resulted in a maximum of 1.8 Watts to my devices. It seems reasonable to me. I measured a maximum of 93,600 LUX outside whereas the standard is based on a reading of about 109.870 LUX. At the standard, the output should be greater than 2 Watts. Further, I was testing on a 40 degree C day and the black fabric helped to increase the temperature of the cells, I am assuming another 15 degrees C. The folded solar cells are a nice size, about the width of a cellphone, useful for keeping in a glove compartment for an emergency. The ten connectors are: USB Mini-B, 2x Micro-USB, Nokia 2mm, Nokia 3.5mm, PSP 4mm, Apple 30 pin dock connector, LG sync for VX5400 and others, Samsung old 20 pin, Samsung new 20 pin (as best as I can see). I am charging a cellphone and a small tablet with the solar charger. This panel should have similar characteristics to others of a similar size and voltage.

Nagyon jól néz ki, majd kipróbálom, ha a nap lemegy. Pop doboz méretarány.

looks really nice, will try it out when the sun is out. pop can for scale.

The item arrived very promptly, and local courier delivered efficiently. 👍Checked and verified it is good for charging under good light. Only catch is the charging adapter does not include Type-C charger. I have to use my own charging cable. Otherwise it is good for most general use when sunlight is abundant.

minden jó - megrendelve 2022.02.27-én és kézbesítve 04.03.2022. Alapvetően ez a rész működik. A jelenlegi napon azonban csak rel. kis elektromosság. 8 óra után kb. Az 5000 mH PowerBank 50%-a

alles gut - am 27.02.2022 bestellt und am 04.03.2022 geliefert. Grundsätzlich funktioniert das Teil. Bei der jetzigen Sonne allerdings nur rel. wenig Strom. Nach 8 Std ca. 50% einer 5000 maH PowerBank

very helpful when you travel. so handy and no need to worry anymore for lowbat celphone batteries! highly recommended for people on the go.
