# Swappable Cell Power Banks The DurCore Tactical Modular Power Bank Supports 45W Fast Charging By Michael Hemsworth | Published 2026-05-26 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/tactical-modular-power-bank References: [gadgetify](https://www.gadgetify.com/durcore-power-bank/) & [kickstarter](https://www.kickstarter.com/projects/904641400/durcore-tactical-power-bank-with-swappable-batteries/)  The DurCore tactical modular power bank is a different kind of external power solution for mobile devices that embraces a modular construction to prevent a depleted battery from rendering it useless. The power bank works on the principle of allowing the battery cells to be swapped out as require rather than limiting the user with a fixed capacity. This will enable users to use 21700-style batteries that can be swapped in and out as they require charging to offer continuous access to 5,000mAh of mobile charging power. The DurCore tactical modular power bank supports [45W fast charging](https://www.trendhunter.com/trends/kuxiu-k1-ultra) and also features a [rugged design](https://www.trendhunter.com/trends/elecom-dec55l9000) that's made with aluminum alloy and ABS. This will give the power bank a durable construction that can be hung on a pack or carried in a pocket without damage. ## Trend Insights (Trend Hunter) - Score: 4.5/10 - Popularity: 29% | Activity: 27% | Freshness: 78% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Mobile](https://www.trendhunter.com/mobile) ## Key Themes ### Why This Trend Is Growing - **Modular Consumer Power:** A shift toward user-replaceable battery modules creates the potential to decouple device lifespan from fixed power packs and enable longer-lived accessory ecosystems. - **Swappable 21700 Battery Ecosystem:** Growing adoption of standardized 21700 cells opens possibilities for third-party cell marketplaces and interoperable charging/swapping infrastructures. - **Rugged Fast-charging Accessories:** Demand for durable, high-wattage portable chargers signals room for integrated solutions combining military-grade build with rapid power delivery. ### Industries Being Reshaped - **Outdoor and Adventure Gear:** Products that allow on-the-go battery swaps and 45W charging could redefine power management for multi-day expeditions and remote work scenarios. - **Mobile Accessories Retail:** Retailers could see a market for modular power systems and compatible cell inventories that shift purchasing from single-use packs to recurring component sales. - **Battery Cell Manufacturing:** Standardized swappable cell demand may drive new cell designs optimized for frequent swapping, durability, and certification across accessory ecosystems. ## Related on Trend Hunter - [Industrial All-in-One Power Banks](https://www.trendhunter.com/trends/aulumu-m10-multicharging-power-bank.md) - [Ultra-Slim Magnetic Power Banks](https://www.trendhunter.com/trends/ultrathin-magnetic-power-bank-5000.md) - [High-Capacity Power Banks](https://www.trendhunter.com/trends/ultrathin-magnetic-power-bank.md) - [Powerful Compact Power Banks](https://www.trendhunter.com/trends/compact-power-bank.md) - [Micro Technology Power Banks](https://www.trendhunter.com/trends/iniu-pocket-rocket-p50.md) - [Solid-Liquid Power Banks](https://www.trendhunter.com/trends/kuxiu-s3.md) - [Safety-Focused Power Banks](https://www.trendhunter.com/trends/movespeed-solidstate-battery.md) - [Inaugural Tech Brand Batteries](https://www.trendhunter.com/trends/dreame-air-power-bank.md) - [Swappable Battery Pack Chargers](https://www.trendhunter.com/trends/coreplus-power-bank.md)
