The Texas Instruments TI-Nspire CX Graphing Calculator is a handheld device with a regular display size and key size, making it convenient for on-the-go use. It operates on power cord or battery, with the added feature of USB connectivity for data transfer. This model is designed for graphing capabilities and comes with a protective cover for added durability. Made in China by Texas Instruments, this calculator is a reliable tool for various office and industrial applications. Tested and works perfectly. No charging cable. I was able to charge it and use it without a cable but I am not sure how strong the battery is. May need to eventually be replaced
