Simply install eight flat-top 18650 lithium-ion cells to instantly create a reliable, high-performance power station tailored to your specific capacity demands.
🌟 Key Product Highlights
- 100% Solderless Assembly: Features a user-friendly, clip-together structural design. Replacing old or dead batteries is seamless—just pop open the shell, swap the cells, and your power bank is brand new again.
- Intelligent LCD Digital Display: Completely eliminates the guesswork of traditional 4-LED indicators. The crisp, integrated digital screen continuously monitors and accurately displays your remaining power level from 0% to 100%.
- Dual USB Output Configuration: Engineered with two separate USB-A output ports (optimized for 5V/1A and 5V/2A or 2.4A delivery), letting you simultaneously fast-charge a tablet and a smartphone without bottlenecking speeds.
- Universal Input Ports: Recharge the power bank seamlessly using either a modern Type-C cable or a legacy Micro-USB cord, eliminating the need to carry multiple charging wires while traveling.
- Dual Emergency LED Flashlights: Outfitted with twin ultra-bright LEDs. Long-press or double-click the tactile power button to transform your portable charger into a dependable flashlight for camping, blackouts, or roadside emergencies.
🛠️ Advanced Safety Protection Suite
Your safety is our absolute priority. The engineered, high-performance printed circuit board (PCB) includes a multi-layered protection chip architecture:
- Over-Charge & Over-Discharge Protection: Prevents damaging your delicate lithium cells by cutting off current at optimal threshold points.
- Short-Circuit Isolation: Instantly shuts down the output if a short-circuit fault is detected, keeping your connected smartphones and tablets completely safe.
- Over-Current & Over-Voltage Regulation: Locks down energy delivery to ensure smooth, stable current streams match your device’s exact intake limitations.
- Anti-Reverse Polarity Shielding: Features specialized structural springs and circuit pathways to help guard the module against damage if a battery is accidentally placed backward.
