“BestBuy calls this the "Philips Sonicare 4100 Power Toothbrush". BestBuy also sells "Philips Sonicare - ProtectiveClean 4100 Rechargeable Toothbrush." Both use model number 4100, but one says "rechargeable"; the other doesn't. What is the difference?”

• The one that I purchased is rechargeable, but it is charged by an USB rather than a standard outlet.
