Mini Solar panel and draining power

Afternoon All,


I have one of these


https://www.amazon.co.uk/RAVPower-UK-RP-PC005-Waterproof-Smartphones/dp/B01FH2HYCW


On sunny days great for charging up my kindle, phone and a power bank to use later.



The only issue is if it goes cloudy or I miss the sun setting it seems to start discharging anything attached. I guess I need something to stop that doing it. But I am not sure what I need, any ideas and it needs to be cheap.



Any ideas. Thanks in advance


Yours

    Hi
    It should have a blocking diode in the circuit to stop this happening.

    Its a portable solar charger. You can fold it up and put away. I know it discharging in low light levels. So need to stop it with something between the charger and the phone/kindle/powerbank I am charging.

    from amazon q&a section.
    As IPod and e readers are low power devices a solar charger of 15 watts or above will charge as quickly as a mains charger in full sun. However the best way to use these solar panels is with a power bank to store the charge . I use my panel for camping to power a phone, tablet, and lights with a rav power 24 watt pane…

    Thats not really answering my question about how to stop discharging when cloudy or at sunset. When for what ever reason I am not around to disconnect items.

    I am aware how to use the product.

    Just a thought. Is it just the phone that discharges? On my phone I can set it up so that some of the power-intensive apps are allowed to run whilst the phone is charging and the phone is in sleep mode. Is it possible that you have some apps set up to do this and the phone thinks it is changing whenever a charging lead is attached?
