🚀 Key Functional & Hardware Highlights
💻 Uncompromising 145W Blazing-Fast Multi-Device Power
Ditch your bulky wall adapters on the go. The Baseus EnerGeek GR11 pumps out a massive 100W single-port speed directly through its built-in retractable cord or its standalone Type-C ports—enough to juices up a 16-inch MacBook Pro to 43% in just 30 minutes! When multiple devices are plugged in, it intelligently splits up to 145W max power across its quad-charging layout to keep your whole ecosystem humming.
🪢 Built-In Tangle-Free 100W Retractable Type-C Cord
Enjoy streamlined cable management wherever you travel. The integrated 60cm ultra-durable Type-C flat cable supports high-current Power Delivery (PD 3.0). Pull it out to your desired length to eliminate desk clutter, and give it a quick pull when done to watch it glide smoothly back into its hidden protective internal housing.
📟 Premium 1.2-Inch TFT Intelligent Color Dashboard
Stay in absolute control with live, comprehensive power telemetry. Moving past simple blinking LED dots, the GR11 features a vibrant 1.2″ colored TFT screen. It continuously tracks real-time battery percentage, exact input/output wattage metrics, estimated remaining charging times, and active fast-charging protocol statuses at a glance.
🧊 Aerospace-Grade Triple-Loop Smart Cooling Tech
High-power output demands elite temperature controls. The EnerGeek GR11 is packed with an innovative Triple-Loop Cooling System that pairs conductive aerospace-grade graphene with advanced Aerogel thermal insulation (thermal conductivity as low as 0.02 W/mK). Together with an AI temperature algorithm, it isolates internal heat from the outer shell to ensure safe, cool high-speed performance.
🔋 SGS-Certified Automotive-Grade 21700 Cells & Low-Current Mode
Built to last for years of rugged use. Utilizing four premium 21700 lithium cells in series, this power bank offers superior energy density and long-term lifespan stability over hundreds of cycles. Need to juice up small accessories? Double-click the power button to trigger the Low-Current Mode, safely charging sensitive gear like smartwatches, wireless earbuds, or action cameras without triggering auto-shutoff.
