Arkon's CAFIQC3 hardwire vehicle power adapter with in-line fuse provides quick charge and is ideal for charging Android and Apple smartphones, tablets, and other devices in your vehicle, especially fleet or commercial trucks. Hardwire this 6-foot power adapter directly into your vehicle's 12V power source and then use the USB-A port to connect your charge cable (sold separately). Installation of CAFIQC3 is simple and includes short circuit and overcharge protection; however, it is strongly recommended that you have knowledge of your vehicle's operation before installing. Note: if using CAFIQC3 on electric forklifts with 36/48 Volt power, a voltage reducer (not included) should be used.
