Travel size design: compact small size (4.8×3.1×1.5 inches) with 5 feet detachable power cable makes this power converter easy to pack and take anywhere you go. Supply 200 watts power converter with two standard USA plugs and four 5v / 2.4a (2.4a per port max) capable of simultaneously charging multiple devices for laptop, bluetooth speaker, cpap machine, electric toothbrush, fan, nebulizer, game console, kindle, tv, dvd players, lights, ipad, and other electronic devices. Worldwide use: 1 eu power cable and 4 international adapters ( us/uk/au/it adapter), step down voltage converts 220/240v to 110/120v, so you could use american electronics in 220v / 240v countries such united kingdom, continental europe, italy, australia, thailand, japan, china etc, more than 150 countries over the world.

Protect eelectronics safety: fan work silent and converter will auto shutdown for surge protection, over-heating, short circuiting, over-current, over temperature, short-circuit and overload, keep you and your devices very safely with small 200w power.

Output current: 5a max(use it within 4.5a); output power: 75w max(use it within 50w, reduce power if the pressure difference is big). Input voltage: dc7-36v ; output voltage: dc1.25-32v (continuously adjustable, default output 17v) 36v to 24v 12v 5v 3.3v 3v. Short circuit protection, output is more than 3a/35w, please enhance heat dissipation. Use as battery charger, high power constant current led drive module, normal step-down modules with over current protection capability.
