I bought it at amazon. It has a regular charger that plugs in to a electrical outlet. The USB charger says for ease of travel use. It comes with a really nice travel case. The charger will fit my digital camera and my Kindle and the adapter plug will fit my Iphone so it's worth having. I just thought it was funny that a toothbrush would come with a USB cord. I never thought to even want one before. ? What next coffee makers? Toasters? LOL
