Nexus Lights products, including the Shapes and Uplight, are powered by long-lasting batteries that offer up to 24 hours of runtime. They feature fast and efficient charging through a USB-C port with Power Delivery. To charge, connect the device to power via its USB-C connector using either a standard USB charger (not included) that can supply a minimum of 1 amp, or the optional Nexus Lights Charging Station (not included). It is recommended to charge the product to 100% before its first use. During charging, the first LED pixel will flash red to green, and when 100% charged, it will be a constant white. This charging status is not visible during normal operation.
