Assuming the Samsung charger is a micro USB, yes you can use the Samsung charger for the HTC One.
From the HTC Radar 4G to the HTC EVO View, HTC's wide range of tablets and smartphones are everywhere. The only problem is that HTC enthusiasts often use their devices too much, and it's easy to find yourself away from home with a dead battery. Buying a spare HTC charger for your tablet or smartphone is the perfect way to make sure you stay online no matter how much you use your HTC Desire or Touch Pro. HTC chargers are available for your car charger, AC outlet and even for your desktop. Charge your HTC mobile device any time, at home or on the go, with HTC chargers.
I would buy the HTC Evo 3D, rather than the HTC Rhyme.
The HTC Evo 3D smartphone uses a "micro-USB" plug which can be purchased at any electronics store, to be plugged into a wall charger, or a car cigarette lighter adapter, or by USB to your PC or laptop. ask around; your friends almost certainly have a spare one. Or buy two; they are inexpensive.
