Philips Sonicare 4100 Plaque Control Rechargeable Electric Toothbrush - HX3689/24

A: Hello! You can use a USB wall adapter to charge the Philips Sonicare 4100 Powered Toothbrush.

A: Companies useUSB on the end of their power cables because it is a low voltaga connection, therefore they do not need to seek the same certifications as a regular plug, therefore making it cheaper.

A: Embrace change. It's going to happen anyway. Resistence to the USB is you keeping one foot in the past and no foot in the future, leaving you in a flamingo stance. Do the bridge in all things.

A: So Phillips wants their customers to replace their bathrm outlets w/ 1 that has a USB port so that WE can use YOUR product? I don't think I'll be remodeling my bathroom so that I can use your product

A: I'm mystified by absence of regular 110V double prong plug. Agree with comment, "who has a USB port in their bathroom?" My home is 30-years old, which is normal.

A: I bought an adapter plug that has both the usb plugin and a standard outlet plugin. It cost me $9.99, its a simple and cheap fix.

A: It’s usb need a charger to plug into outlet

A: yes, this is so unnecessary. I wish to have a normal plug, especially for bathroom to have usb to have extra option for water access, I am surprised they want to take that risk for few cents to keep

A: The new toothbrush will almost assuredly work in your old charger base, too; and you won't have to defer to the new USB one. Keep it, though. I'm not an electrician and, in theory, I could be wrong.

A: Its usb, you will need to buy the plug.

A: I have a GFCI with USB charging ports in my bathroom. No issues for me.

A: Hello! It is recommended to replace your Philips Sonicare Brush Head every three months of normal use (brushing twice a day) or when the blue indicator bristles wear out.

A: The indicator says every 3 months. Most heads come with a colored indicator to change and if you get heads that have the “brush sync” technology the toothbrush will actually alert you to this.

A: Hello! It is recommended to replace your Philips Sonicare Brush Head every three months of normal use (brushing twice a day) or when the blue indicator bristles wear out. One reason is that brush heads can get weary and will be less effective in removing plaque.
