Using this mini electric juicer is super easy. First, open the cup and put your fruits or vegetables inside. Then close the lid tightly. Press the button and in just 40 seconds, you'll have fresh - squeezed juice. You can charge it in different ways - in your car, with an adapter, or a power bank. When charging, make sure the charging current is 1A. Don't overfill the cup, as the capacity is only 300ml. After each use, clean the juicer with water and a soft cloth. Keep it in a dry place. If the battery runs out, just charge it fully again and it can work about 15 times. This juicer is made of food - grade plastic, so it's safe for your drinks.
