III. Eight Core Selling Points
1. 20000mAh High Capacity, Maximum Battery Life
20000mAh 1. High-density battery cells allow for 4-6 recharges of a mobile phone in daily use, eliminating the need to constantly search for outlets during long business trips or travels, and banishing battery anxiety. The high energy density of the battery cells is achieved through a well-controlled size, preventing excessive weight.
2. Integrated three-cable design eliminates the need to carry separate cables. The device incorporates three integrated charging cables, covering 99% of digital devices on the market:
Lightning cable: Compatible with all Apple devices including iPhones
Type-C cable: Fast charging for new Android devices, tablets, and laptops
Micro cable: For older Android devices, Bluetooth headsets, and small appliances. One cable provides multiple uses, saving you the hassle of carrying a separate data cable. Charge your phone easily in your pocket or bag.
3. PD22.5W bidirectional fast charging doubles the charging speed.
Supports PD22.5W input + output fast charging: Quickly replenishes most of the battery in 30 minutes, and provides stable fast charging for tablets and lightweight laptops; simultaneous charging of multiple devices can reach a total output of up to 80W, maintaining speed even with multiple users.
4. Circular LED Digital Display: Clear Battery Level Instantly
The front-facing circular high-definition digital display shows the remaining battery level accurately from 1% to 100% in real time. No more relying on indicator lights for vague battery estimations; clearly determine remaining battery life before leaving home and plan your charging accordingly.
5. Anti-Slip Mesh Body: The front features a 3D diamond-patterned anti-slip texture, preventing slippage even with one hand. The matte, fingerprint-resistant shell resists oil and fingerprints over long-term use, offering a smooth feel and comfortable grip.
