The Portable Charging Problem: Paying for Capacity You Don't Control
Every commercial power bank is a compromise between the capacity advertised and the capacity delivered. The cells inside are chosen by the manufacturer for cost, not quality. The circuitry is designed to meet a price point, not a performance standard. And when the power bank fails — as they all eventually do — you replace the entire unit rather than just the cells that have degraded.
The DIY 18650 / 21700 Power Bank Case from Elanique gives you control over every element of your portable charging solution. Choose your own cells. Know your own capacity. Replace individual cells when they degrade rather than replacing the entire unit.
Dual Cell Compatibility: 18650 & 21700
The case accommodates both 18650 and 21700 lithium cells — the two most widely available high-quality lithium cell formats. The 21700 format offers higher capacity per cell than the 18650, allowing you to build a more powerful power bank in the same physical footprint. The flexibility to use either format gives you access to the widest possible range of quality cells from reputable manufacturers.
5W Charging Module: Efficient & Reliable
The integrated 5W charging module provides efficient, reliable power delivery to your devices. The SMD (surface-mount device) construction ensures compact, reliable circuitry that delivers consistent output without the voltage fluctuations that can damage sensitive electronics.
Integrated Stand: Hands-Free Convenience
The integrated stand allows you to prop up your phone while it charges — the practical detail that makes charging at a desk or bedside table genuinely convenient. Watch content, take calls, and monitor notifications without picking up your phone while it charges.
