Customers find the solar panel well-constructed, convenient to fold, and easy to carry in a backpack. The build quality and portability receive positive feedback. However, the power output and charging performance show mixed results – while some say it gives great power and charges well, others report it doesn’t produce the advertised 40 watts and fails to charge devices as expected. Moreover, battery life experiences vary, with some reporting a full iPhone charge in about an hour while others struggle to get a full charge. Additionally, opinions on value for money are divided between those who find it decent and those who don’t think it’s worth the money.
