The article critiques solar-powered power banks, highlighting their inefficiency and safety concerns when left in direct sunlight. Despite their appealing concept, the tested devices fail to charge effectively, often not reaching even halfway, and can overheat to dangerous temperatures exceeding 80°C. The author reports that none of the solar power banks tested could be recommended and suggests considering alternatives like solar power stations or using vehicle charging instead, as the convenience of simply attaching solar panels to power banks does not deliver effective results in practice.
Using solar-powered power banks has proven ineffective and potentially dangerous, as they do not charge adequately due to high temperatures that stop charging.
Despite the idea of solar-powered power banks being appealing, my tests show they fail to charge effectively and may overheat lithium-ion batteries.
