Has anyone had any luck with aftermarket power supply's. I'd like a car/ac charger or a stand alone power pack. I usually use my DEXIM but it does not work with the Behold 2. I've tried a car charger/battery unit by Wireless Gear that said it was compatible with all Samsung phones, it came with 5 power tips and a USB outlet that still would not work, even using the OEM USB cable. Any suggestions would be appreciated. I will go with OEM Samsung if necessary, but there selection is limited.
