Compatible Toothbrush Models

This USB charger cable fits Fairywill models 507, 508, 917, D1, D3, D7, D8 and Bitvae D2, R1, R2, S2. It also supports 7AM2M AM105 and AM110 sonic toothbrushes. The 3.5 mm plug matches the DC charging port on these specific handles.

Power Source Flexibility

The USB-A connector plugs into any standard USB power source such as a power bank, wall adapter or computer port. This replaces the original proprietary charging base and lets you charge the toothbrush wherever a USB socket is available. The 3.3 ft cable length provides reach without excess slack.

Sustained Charging Behaviour

The cable delivers a steady 5 V DC supply through the 3.5 mm barrel connector for the duration of the charging cycle. It maintains a consistent connection without overheating during the typical multi-hour charge required by compatible toothbrushes. The fixed 3.3 ft length avoids voltage drop that longer cables might introduce.

Questions about this item

How long is the cable before it becomes taut during daily charging?

The cable is 3.3 ft long, giving enough reach from a wall charger or power bank to the toothbrush handle.

Does the 3.5 mm connector stay cool when the toothbrush charges overnight?

The cable carries only DC 5 V at low current, so it remains cool to the touch during extended charging sessions.

Which toothbrush models must I already own for this cable to fit?

It fits Fairywill 917, 508, 507, D1, D3, D7, D8; Bitvae D2, R1, R2, S2; and 7AM2M AM105 and AM110 — but not AM101.
