I have used two different USB instruments, of course, not calibrated and more for home use, for an amateur assessment as part of a product review but adequate I guess.
In the sun managed the panel pretty good, at about 5 volts, a current of approximately 0.5 A (2.5 watts) to deliver. Some readings that I could read in the intermediary devices incl. The conversion to Watts.
They vary depending on the intensity of sunlight, the connected device (Power bank, mobile phone) and, depending on the meter:
4,85V 0,72A = about 3.49 watts
5,02V 0,47A = about 2.35 watts
5,11V 0,44A = approximately 2.25 watts
5,09V 0,54A = about 2.75 watts
5,07V 0.63A = 3.19 Watt ca.
5,07V 0,53A = about 2.69 watts
All Indoor - but before an open window with direct sunlight! I have to also two photos posted.
Much more energy and does not produce my original Samsung 1A plug PSU lt. Of instruments and I think in the summer months can be safe from the solar panel bring out a lot more, the specified maximum output of 9 watts seems under ideal conditions as realistic.
Indicated the panel with 1.8A at 5V, so 9 watts, the charging electronics of the panel should runterregeln also fits the performance, depending on the device in order to avoid overloading.
So who in the great outdoors its devices (eg smartphone, Navi, MP3 Player, Bluetooth speakers where they may be just loaded with 5V USB) would independently from an outlet store, is so dead right on this unit. I can well imagine that a practical companion when camping or in the swimming pool is.
Delivered the Ravpower SolarCharger RP-SC01 with multilingual user manual (incl. German), 4 snap hooks, which fit into the D-rings of the solar panel, a warranty card and a Thank you for your purchase-card.
