Review on 25W Bendable Solar Panel for Portable Car Battery Charging with 12V Cigarette Lighter Plug - Lightweight and Flexible Design by Keith Alvord

I should have read the reviews on this product before buying. Yes the wiring and connectors are similar to the kit but the main issue was that the voltage from the solar panel was only 4.3vdc in full sun. Of course, given that I used a 12V battery, this was useless. There may be an error in the terminal block, which has a male output and a USB output. In any case, 4.3V will not charge an iPhone etc. and certainly not a 12V battery.
