The smallest "Trinity 50" in the series is 5.5 cm in diameter and 30 cm high when folded. It weighs only 650 grams, so it shouldn't be too much of a pain to carry around in a backpack.
It has a built-in 7,500mAh lithium-ion battery and can charge a general smartphone 3 to 4 times when it is fully charged.
The "Trinity" series also features that the blade can be set up in two ways. It can be set horizontally to make the blade more susceptible to wind when the wind is weak, and vertically when the wind is strong.
In addition to the Trinity 50 with 50 watts of power, four different sizes are available: the 400 watt Trinity 400, the 1,000 watt Trinity 1000, and the 2,500 watt Trinity 2500. The Trinity 2500, which produces the most electricity, is designed not only for portability but also for home use, with a built-in lithium-ion battery with a capacity of 300,000mAh. According to the distributor Janulus, the Trinity 2500 can also charge electric vehicles.
Janulus is currently looking for investors on kickstarter. Trinity 50 is available with a $ 399 investment. Shipment is scheduled for around April 2016. The Trinity 400 is available for $ 1,099, the Trinity 1000 for $ 2,999, and the Trinity 2500 for $ 5,999.
