While mobility is a great thing, all our gadgets run with batteries and requires a recharge - sooner or later. Having a single charger for every device with you might be for you as inconvenient as it is for me. However, sometimes one and one fits - in this case the RoyalTek RTB-1000 Bluetooth GPS receiver and the Xda II (aka HTC Himalaya) charger which works perfectly.
Most RTB 1000 sales packages exclude the AC adapter but includes the car charger only. :-(
Nevertheless, ff you want to save your money and want to save weight, the HTC Himalaya charger also charges the RTB-1000 and therefore you don't have to buy the separate available AC adapter, nor you have to carry two chargers. :-)
Not sure if other (Pocket PC) chargers does it also but at least the Xda II charger does it fine - I'm using it for some time with my RTB-1000 now and haven't noticed any damages yet.
