Portable 5W 12V Polysilicon Solar Panel Battery Charger For Car RV Boat W/ 3m Cable
A part of the review has been auto-translated.
Well packaged and excellent delivery time (11 calendar days from order). I use small solar cells on many of my projects to keep them independent of wired power supplies. I am skeptical about the 5W claim, but I have used a few of these and they are certainly good enough to maintain charge in a LIPO. I use them with a custom self-designed MPPT controller.
I received the two solar panels undamaged and in good working condition. I checked the output voltage and the output voltage of both solar panels are conform the specifications
quickly arrived it works perfectly only I can recommend.
Bandysim prijungti prie vandens siurbliuko. Trupučiu ką kreivas. Bet gal veiks gerai. Rekomenduoju.
Small solar panel suitable for charging some Li batteries and power small devices. Quick shipment.

Perfect as from description arrived in 35 days in Italy all ok only to try if it does its job, Seller recommended and reliable and serious thanks a lot..
Over rated for its size with decent NOCT factor under temperature and well made. Measured at continues 150mA at short circuit , open circuit voltage 14V and rather close to 2W max. under real conditions. Suitable for Lithium chargers of 2-3 Li-Ion in series (max voltage 12,6V with current approximately 110mA ) and definitely not for 12V Pb batteries that require 18V open circuit voltage. In fact at this size 2W is the max. power you can get with all similar small panels of good quality.
Very satisfied, works very well.. 😊
great product for the price thay even have two little legs so that you can angle it a bit toward the sun
