1. Automatic identification of positive and negative poles, while supporting dual output, seat charger and direct charge can be used simultaneously 2. Side-sliding humanized design, the shortest distance is 32mm, the longest stretchable to 47mm 3. Adopt global voltage design, intelligent battery charging control circuit, anti-overcharge 4. Imported IC components, high conversion efficiency and stable performance 5. With output over-current and short-circuit protection, safe and secure 6. High output voltage output (4.2V) is more efficient in charging 7. The material is completely made of high-grade PC fireproof and shatterproof shell 8. Fully self-stop, prevent battery overcharge, safe and reliable 9. With a straight plug, you can plug in the power directly to charge the battery, easy to use 10. Input: AC 100V-240V 50/60Hz 150mA 11. USB output: DC 5.2V 1250MA 12. Charger output: DC 4.35V Product keeper: 1. Waterproof and moisture proof. Electronic products, when exposed to water or exposed to humid air for extended periods of time, can cause corrosion or oxidation of internal electronic components 2. Anti-fall and shockproof. Be careful when using it normally, and do not rude it. Do not throw, knock or shake. May destroy the charger internal circuit board 3. Anti-strength chemicals. Do not use harsh chemicals, detergents or strong detergents to clean the charger. Appearance stains can be scrubbed with cotton and alcohol
