In 2018, as part of ongoing efforts to bolster the off-grid solar market, Lighting Global Quality Assurance investigated the USB charging performance of off-grid solar products. Laboratory tests were conducted to assess the USB compatibility and charge times of product combinations. The testing demonstrated both successful charging performance and also identified problems that may occur when off-grid products are used to charge mobile devices.
