Advantages of Rechargeable USB Batteries

1. Long cycle life

A-grade 14500 lithium cell: Uses high-quality 14500-spec lithium-ion cells (equivalent to AA size), ensuring stable performance through strict quality control, compatible with various AA battery devices.
1000-cycle lifespan: Supports up to 1000 charge-discharge cycles, retaining ≥80% capacity after 3 years of use*, far exceeding ordinary nickel-metal hydride batteries (≈500 cycles) and disposable batteries, with lower long-term usage costs.
*Note: Cycle life based on standard test conditions (0.5C charge-discharge, 25°C environment).

2. Constant voltage output technology, strong device compatibility

1.5V constant voltage: Built-in balanced current PCB board regulates voltage output in real time, maintaining stable 1.5V power supply throughout. Perfectly replaces traditional 1.5V dry batteries (e.g., AA/AAA alkaline batteries), solving the voltage decay problem of ordinary lithium batteries (which discharge from 4.2V to 3.0V gradually).Wide device compatibility: Works with 1.5V-powered smart home devices (smart locks, robot vacuums), consumer electronics (wireless mice, keyboards, gamepads), and outdoor tools (headlamps, flashlights), etc., requiring no device modification for direct replacement.

3. High energy density, long-lasting power

3300mWh large capacity: Single cell delivers 3300mWh energy density (≈850mAh/3.7V), a 65% increase over same-size alkaline batteries (≈2000mWh) and 83% over ordinary nickel-metal hydride batteries (≈1800mWh). Single charge supports longer device operation (e.g., wireless mouse battery life extended from 1 month to 3 months).

Sustained high-power output: Low internal resistance design (22mΩ-45mΩ) supports instant high-current discharge, suitable for high-power devices (e.g., flashlights, electric toys), avoiding "power shortage" caused by high internal resistance in ordinary batteries.

4. Low self-discharge design, worry-free storage and backup

Ultra-long storage: Adopts low self-discharge technology, losing ≤5% charge after 1 year of storage at 25°C, far better than ordinary nickel-metal hydride batteries (≈30% self-discharge rate/year). Ideal for long-term backup scenarios (e.g., emergency flashlights, spare remote control batteries).

Ready-to-use feature: No frequent recharging needed; use immediately after removal, reducing the embarrassment of "dead batteries". Especially suitable for infrequently used but always-ready devices (e.g., smoke alarms, electronic door locks).

5. USB-C fast charging, revolutionary charging experience

Type-C direct charging port: Built-in USB-C charging port eliminates the need for extra chargers or docks. Directly charge via USB-C ports of mobile phone chargers, laptops, power banks, etc., saying goodbye to the hassle of finding dedicated chargers for traditional batteries.

5V 1A-3A fast charging support: Compatible with wide input current (1A-3A), reaching 80% charge in 1 hour (3A fast charging mode) and full charge in 2 hours—3x faster than ordinary nickel-metal hydride batteries (4-6 hours slow charging).
Reverse compatibility design: Supports 5V input voltage, usable with old 5V/1A chargers to avoid device compatibility issues.

VI. Dual guarantees of safety and environmental protection

Multiple circuit protections: Built-in overvoltage, overcurrent, and overheat protection chips automatically cut off power during charging to prevent battery swelling or fire risks. Certified by international standards like UN38.3 and RoHS for safer use.

Green sustainability: Rechargeable design replaces disposable batteries—one cell saves ≈1000 alkaline batteries, reducing heavy metal pollution and complying with EU Battery Regulation environmental requirements.
