What to know before buying

Listing details to confirm

The listing identifies the product as rechargeable with a 4000mAh battery, but also says one included C battery is required. Confirm the actual power and charging arrangement. The stated dimensions and weight appear together as one dimensions entry, so their labeling is unclear. The listing also specifies use with 5V/2A adapters only. Temperature settings are presented in Fahrenheit and Celsius in the feature text, but the listed sequence does not consistently pair each conversion.

A good fit for

Beard grooming at home or while traveling, especially for buyers who want cordless operation.

Frequently asked questions

What temperature settings are listed?

The listing gives three settings: 320℉, 356℉ and 392℉. It also provides Celsius equivalents, but the sequence does not consistently pair each conversion, so confirm the displayed temperatures before purchase.

What charging adapter does it require?

The listing says it is compatible with 5V/2A adapters only. It also mentions an included C battery despite describing the brush as rechargeable, so the power arrangement is unclear.

Does the brush shut off automatically?

The listing claims automatic power-off after 20 minutes of non-use.

Is a travel bag included?

The feature text says the kit comes with a travel bag, but the package contents are not separately itemized. Check the selected listing for the included kit.
