BTECH USB smart converter cable turns standard 5V USB into regulated 12V DC through a 5.5mm barrel plug for charger bases labeled 12V DC input. It powers compatible BTECH DMR-6X2 / DA-7X2 bases and AnyTone AT-D868UV, AT-D878UVII and AT-D890UV bases, plus TYT and other 12V bases with the same jack.
Feed it from a vehicle USB port, computer USB, power bank, AC-to-USB adapter, or USB solar output with enough current. Check the voltage printed near the base DC jack first, because 10V-input bases are not compatible.
