Chelegance JNCRadio CS-818 Auto Tuners are the perfect companion to the Yaesu FT-818/817 transceivers and come equipped to fully control the tuning process for these transceivers. The CS-818 can operate from 1.8–54 MHz and is more than just a tuner, it also features an SWR and power meter. The  1.3 in. OLED display will show current SWR and Power input readings along with a battery level indicator. Its compact size and up to 50 hours of battery life make the CS-818 perfect for SOTA, POTA and other QRP portable operations. Latching relays will hold their positions when the CS-818 is turned off, making ultra-low power consumption possible. The built-in 3400 mAH battery is rechargeable with the included USB-C cable or an optional 13.8 VDC charging port (cable not included). A CAT cable for the FT-817/818 transceiver is included. The CS-818 will also work with other transceivers if the 30 W PEP power limit is maintained.
