W4RT Electronics has developed a really first-class fast charger for the FT-817 One Plug Power Plus. It charges the 2700 mAh OPP+ in just over 2-1/2 hours, small (4"x2.8"x2.3"), lightweight (about 6 oz), and versatile. The charger uses the standard Molex RC connector typical of the Radio Shack 9.6 VDC NiMH battery packs and the OPP fast-charge cable (supplied with the OPP). This technique allows you to use the OFC-817 to quickly and easily connect to the OPP or to other 9.6 VDC NiMH battery packs. The power input to the OFC-817 uses a 4-pin connector (two for AC and two for DC inputs). The supplied wall wart plugs connects via this connector. You may also use any DC supply to power the OFC-817 as long as the voltage is 17 to 19 VDC. So you can use your bench supply or even a solar array when out on those deep-country hikes!
12v power supply not included.
