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 regulator. Linear is not efficient. 3) There is a XL6008E1 buck/boost converter chip running all the time, boosting battery voltage up to 16.5V for the MPPT circuitry. It draws 13mA and always stays warm to the touch. 4) There is a TLP250 photocoupler MOSFET gate driver. It is always active and also runs warm. 5) There is a single 510 ohm chip resistor that runs hot and dissipates 175mW at no load! 6) Then there are 3 to 5 LEDs on all the time, and each one likely draws 1-2 mA. So this charge controller is not suitable for small solar panels less than 75W because it is just not efficient. For those I would recommend a small & simple fixed-MPP controller like Banggood's "MPPT Solar Panel Controller 5A DC-DC Step Down CC/CV Charging Module" which is much more efficient. It draws 11mA no-load, which you can reduce to zero using a diode. You will need to add a cutoff circuit when using a load. 10A automotive relay-based cutoff boards are cheap and easy to find. The MPP tracking algorithm programmed into the CPY-2410 is not very good. It hunts around a lot and can get stuck. It doesn't like to move up as easily as it moves down. On a positive note the build quality inside is good, with all brand name electronic components. Except mine came with the paper backing still attached to heat shrink material for 5 of 7 heat-sinked components. You will want to open and check yours. Max

I tested for 3 days and it's working like mppt charge cantorler.. And it's very high quality... Really primuim look.. Thanks for these item Banggood

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
