  • This style of solar chargeable flashlight has a bit of a history with many of them using non rechargeable batteries and fake, reject or unconnected solar panels. So take a gamble. Is this one real or fake?

    The listing this one came from is:-

    http://www.ebay.co.uk/itm/262864366308

    Spoiler below:-

    The flashlight is a good source of parts like the small solar panel that puts out useful current, and the LIR2032 rechargeable lithium button cell with tags. The solar panel puts out a surprising 8V open circuit and 20mA short circuit when tested against the front of a 20W LED floodlight. The PCB is glued to the solar panel and may damage it if removed, so probably better left on, even if the components have to be removed to make it flatter.
