All ISOtunes products come with a micro-USB charging cable, allowing them to be recharged wherever you have access to a USB port, such as through a computer, wall outlet, or adapter.
After plugging the USB end into a USB port, locate the charging port on the battery module of your ISOtunes product, remove the safety flap, and insert the micro-USB end into the charging port. For detailed information on the LED charging light, and other important charging information, please consult your product's user manual.
Please note: do NOT charge your ISOtunes Sport product using a "high power" or "fast" adapter or power source above 5V or 2 Amps. This may short-circuit the product and create a defect.
