DUO and AURA are the latest solutions launched by FEELM at CHAMPS TRADE SHOWS. Judging from the pictures released by FEELM officially, FEELM DUO is an e-cigarette solution with a left and right magnetic attraction design. Its oil tank is fully transparent, and there may be a smaller capacity independent battery below the cartridge, which can support the independent use of the device. The battery component part of DUO does not feature an interactive screen. Only the remaining battery capacity is displayed on the battery base. Additionally, there is a hook on the top of the battery, which seems to be able to be connected to a lanyard or backpack, making it convenient to carry.
FEELM AURA adopts an upper and lower structure design. The upper part of it is a considerable transparent oil tank, which is said to provide 50,000 suction times. The lower part of the product integrates the battery and other core components and is equipped with a small screen for visually displaying the battery level. FEELM officially claims that it also has the “Adjustable lce” (cooling sensation adjustment) function.
