This charger for both USB, AC and cigarette lighter has a rather nice design. Unlike the various criticisms, the outlet runs problem (so the concern had to be resolved). It has two USB plugs. You can either put two devices that consume 500 mA or one that consumes 1000. What is nice is that it works in industry and car. Although this is a somewhat bulky car charger (there are smaller), it is ideal to go on trip. A cover protects the part that plugs. Correct product.
