1Coque.com’s Rigorous Selection Criteria

To ensure a reliable and long-lasting experience, 1Coque.com applies a demanding selection grid, inspired by expert recommendations and industry best practices:

• Verified Real Capacity: We prioritize batteries whose actual (mAh) capacity matches what’s advertised, so you won’t be disappointed in real-world use.

• Appropriate Output Power: Every model must provide sufficient output power (in watts) for fast charging your devices, whether it’s a smartphone, tablet, or connected accessory.

• Universal Connectivity: Our batteries offer at least one USB-C port (often bidirectional), one USB-A port, and sometimes a micro-USB output, for maximum compatibility with all your cables and devices.

• Certification and Safety: We require CE and RoHS certifications (for European compliance and restricted hazardous substances), as well as electronic protections against overheating, overvoltage, short circuits, and overcharging.

• Build Quality: Materials, circuit robustness, and lithium cell reliability are checked to ensure long life and optimal safety.

• Advanced Features: We favor models with fast charging (Power Delivery, Quick Charge), wireless charging (Qi), and precise LED indicators for battery level.

• Portability and Design: Compact format, controlled weight, and ergonomic design for easy daily use and transport are essential.

Capacity: Choose According to Your Needs

The capacity of an external battery, expressed in milliampere-hours (mAh), determines how many times you can recharge your devices. Here’s how to choose:

• 1,000 to 5,000 mAh: Perfect for emergency top-ups or for small devices (earbuds, smartwatches, e-readers). Ultra-compact, they fit in a pocket or handbag.

• 5,000 to 10,000 mAh: Ideal for one to two full charges of a standard smartphone, or a single tablet charge. A great balance between autonomy and portability, suitable for a day out or regular city use.

• 10,000 to 20,000 mAh: Designed for heavy users, travelers, or professionals. These allow multiple smartphone recharges, tablet charging, or even powering a compact laptop or several devices simultaneously.

Note: The higher the capacity, the bigger and heavier the battery. Find the right balance between autonomy and bulk for your lifestyle.

Power, Connectivity, and Compatibility

• Output Power: For fast charging, choose a battery delivering at least 18 W (30 W or more for tablets and laptops). Check for compatibility with Power Delivery (PD) or Quick Charge (QC) protocols to optimize charging speed.

• Number and Type of Ports: Multi-port models (USB-A, USB-C, sometimes Lightning or micro-USB) let you charge several devices at once. Some models also offer wireless charging (Qi), ideal for compatible smartphones.

• Universal Compatibility: Our batteries are tested with a wide range of devices (iPhone, Samsung, Xiaomi, Oppo, Huawei, OnePlus, tablets, earbuds, watches, e-readers, etc.) to ensure efficient and safe charging, regardless of brand.
