Why Our Power Banks Are Safe
Spotting Fake Power Banks
1. Weight Check: A genuine 20,000 mAh pack cannot weigh under 350 grams due to lithium cell physics. 2. Wattage Truth: Fake packs advertise 65W but throttle to 10W after 3 minutes. 3. Certification: Inspect for laser-etched CE/FCC marks and serial validation.
Fully certified to rigorous CE, FCC, and RoHS standards. Our integrated Battery Management System runs 100 micro-checks per second to eliminate overheating and voltage spikes.
