    I recently got my CPY-2410. The "no load current" is specified as "<10mA" but this is not true. When the battery is first plugged in and the solar panel is dark, no-load current is 74mA! After one day/night cycle the no-load current drops to 52mA. There are many parts of the internal circuit wasting power, including: 1) The XL4201 DC-DC switching buck converter draws almost 5mA all the time (even with no USB connector plugged in). 2) 5V for internal circuitry is supplied using a LM317T linear buck

    works nicely, easy to set up, it is cheap, ill use it on a bike trip to charge the ebike battery. it makes a slight buzz while working, very subtle, but noticeable so dont put it next to your bed

    I made the initial mistake of not reading the instructions (brief but readable), and so neglected to plug it into a battery first. Once I figured out that it needs a battery to run it, all was well. Seems to do a good job. Converts 18v from panel to 12v (13?) for the car battery as well as 5v for the USB plug.
