Long Lasting Rechargeable Sonic Electric Toothbrush – PTR-C4, PTR-C8 & PTR-C9S IPX7 Waterproof Toothbrush For Home & Travel

Nothing ruins a trip or daily oral routine faster than an electric toothbrush running out of power unexpectedly. A reliable long lasting rechargeable sonic electric toothbrush solves this common trouble. Our PTR series includes PTR-C4, PTR-C8 and PTR-C9S models, all built around high-performance 2000mAh lithium batteries, combined with efficient low-power motors and full IPX7 waterproof construction. With soft rounded Dupont bristles and multiple customizable cleaning modes, these toothbrushes suit adults with normal teeth, sensitive gums and users who frequently travel away from power sockets.

Core Advantages of Our Long Lasting Rechargeable Sonic Electric Toothbrush Lineup

• 2000mAh High-Capacity Lithium Battery: Every unit houses a stable 18650 rechargeable battery. After a full 4-hour Type-C charge, the toothbrush supports over 6 hours continuous working time. For daily twice-daily brushing, it can operate for weeks without frequent recharging.
• Energy-Saving Sonic Motor: Optimized motor circuit design reduces unnecessary power consumption while maintaining stable vibration frequency. Different modes adjust power output intelligently to extend overall service cycle.
• Universal Type-C DC 5V Charging: Compatible with power banks, laptop USB ports, wall chargers and car chargers. Perfect choice for campers, business travelers and overseas tourists who lack fixed charging sources.
• Full IPX7 Waterproof Standard: The whole body withstands immersion in 1m deep water for up to 30 minutes. You can rinse the toothbrush directly under running water after brushing. Avoid long-term exposure to hot steam to protect internal electronic components.
• Ultra-Soft Dupont Bristles: Tips are smoothly rounded to prevent scratching gum tissue. Gentle vibration paired with premium bristles effectively clears plaque without triggering gum bleeding, friendly to users with sensitive enamel.
• Smart Oral Care Timer: Built-in standard 2-minute brushing timer with 30-second zone reminder, guiding users to evenly clean four sections of the mouth for comprehensive cleaning results.

Battery Safety Protection System

To extend the service life of our long lasting rechargeable sonic electric toothbrush, we equip each device with a multi-protection circuit board. It supports overcharge protection, overdischarge protection, overcurrent protection and short-circuit protection. The toothbrush automatically locks and cannot be turned on during charging, effectively avoiding circuit damage caused by improper operation. When battery voltage drops too low, vibration reminder and flashing light will alert users to recharge timely.

Buying Tips for First-Time Users

1. New users with sensitive gums are advised to start with Gentle mode to slowly adapt to sonic vibration.
2. Charge the device fully before first use to activate battery performance.
3. Replace detachable Dupont brush heads every 3 months to guarantee cleaning efficiency and reduce bacterial growth.
4. After each use, rinse the toothbrush and place it in a dry and ventilated location.
