This translator earned The Best rating from the Hammacher Schlemmer Institute because it is the only one of its kind that has 13 built-in languages, 40 additional online via WiFi, or all 53 languages via its global SIM card. Ideal for travel and business, it verbally translates 13 built-in languages, including Chinese, French, German, Italian, Japanese, Korean, Russian, and Spanish. When connected to WiFi, it can access an additional 40 languages; when out of WiFi range, its global SIM card still accesses the 40 additional languages, ensuring two-way verbal communication. Each side of the device has an integrated microphone that captures, translates, and “speaks” dialogue to another person up to 50 words in one translation. Unlike text-only devices that require one to enter each sentence word for word, one simply talks into the translator as if engaging in real conversation. Charges via AC with included USB cable. 5 1/2" L x 2" W x 3/4" H. (5 oz.)
