Banggood

value for money ... quality product... durable product... made up of good material...

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

does not seem to work as MPPT

entrega rápida ,produto de qualidade e funcional

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

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.

Snelle en goede levering, product goed verzorgd.

Good performance and good quality. I satisfied.
