HAWOK Prtable Coffee Maker 12V Travel Espresso Machine, Single Cup 8 oz

I didn't use the coffeemaker. My poor rating is for false advertising, zero customer service from the seller, %26 no help from Walmart. The description said it could be powered by an outlet %26 a car battery, which was just what I wanted. Walmart's bot verified that "outlet" meant an electrical outlet, but to be sure, I emailed the seller to confirm. I was promised a response in 48 hrs but never got one. I appealed to Walmart but never got a response from them either. I ordered it anyway, %26 when it came, I was encouraged to see that the picture on the box clearly showed the coffeemaker being plugged into a household electrical outlet. But it can't be. The only cable included is for a 9 volt car cig. lighter, %26 there is no place to connect a 220 volt cable, nor do the instructions make any mention of it. Big disappointment at that price. I'll be sending it back.
