Composition: PC that is fireproof Two devices can be charged quickly and simultaneously with a dual USB wall charger, and the performance is more reliable. A single port's peak current can reach 2.4A, which doubles the charging speed when compared to 1A charging. Integrated safeguards to prevent excessive labor. 110–240V input voltage is perfect for international travel. PC refined shell, resistant to high temperatures and fire. 110-240V 50/60Hz 0.5A input Maximum Output: 5V/2.4A = 12W
