Review on 🌞 5Pcs 5V 300mA Poly Mini Solar Cell Panel Module DIY for Light Toys Charger | 104mm x 140mm - uxcell by Corey Singh

All these small solar modules from uxcell are of very good quality, durable and have full power as advertised. They are ideal for building small solar chargers for AA or AAA batteries and any 2 cell battery holder. I placed the solar panel on one side of a small piece of wood and the battery holder on the other to keep the batteries from overheating in the sun. If you like this idea, just remember to use rechargeable batteries. The panel voltage should be about 2 volts higher (5 volts) than 2 batteries connected in series (3 volts).
