The Power Bank Problem: Buying Capacity You Can't Verify
Commercial power banks are a black box. The capacity printed on the label is rarely the capacity you actually get — manufacturers use inflated mAh figures, low-quality cells, and inefficient circuitry that delivers a fraction of the advertised power. You buy a 20,000mAh power bank and wonder why it only charges your phone three times instead of six.
The 18650 Power Bank Battery Box from Elanique takes a different approach: build your own. By using your own 18650 lithium cells — the same cells used in high-quality laptops, torches, and electric vehicles — you know exactly what capacity you're getting, from cells whose quality you've chosen yourself.
8 or 10 Cell Configuration: Scalable Capacity
The 8 or 10-cell configuration allows you to choose your capacity based on your needs. With quality 18650 cells rated at 3,000–3,500mAh each, an 8-cell configuration delivers 24,000–28,000mAh of genuine capacity — enough to charge a modern smartphone 6–8 times. A 10-cell configuration scales this further, providing exceptional capacity for extended travel or multi-device charging.
Dual USB & Type-C: Universal Compatibility
The dual USB output allows simultaneous charging of two devices, while the Type-C port provides compatibility with modern smartphones, tablets, and laptops that have moved to the USB-C standard. The combination covers virtually every device you might need to charge — from older USB-A devices to the latest USB-C flagships.
Portable Shell: Compact & Durable
The battery box shell provides a compact, durable housing for your cells that is genuinely portable — sized to fit in a bag or large pocket without the bulk of a commercial power bank of equivalent capacity. The hasp closure keeps the cells secure during transport.
