Reviewer's comments on physical characteristics and perceived quality

This box is a weight of 149 grams with accumulators, because these are owners.

I use the plural because I unscrewed the plate to check the type of battery (2 x 18650).

A box that seems good, but the turntables remain sensitive to scratches. It's inevitable, every time you set up your atomizer, the support will be marked.

The buttons are well integrated in the box, stable and ergonomic.

Their positioning is comfortable and the interface is clear and visible.

We are on a nice design, typical of the range.

Reviewer's comments on functional features

The Istick 50W is an improved and battery-based version of the iStick series. On peut choisir la tension de sortie entre 2V et 10V ou bien la puissance entre 5W et 50W avec  une capacité de 4400 mah pour une longue utilisation. Its connector is mounted on a spring, allowing a flush mounting with the atomizer, with a brass pin and a solid thread in acier inoxydable résistant à l’usure. De plus, l’Istick 50W has fonction supplémentaire d’alarme de température qui permet une bonne sécurité, surtout en power-vaping. If the temperature of the device is higher than 70 ℃, the output will be cut off automatically and the display will show the "temporary protection" for 5 seconds.

The rounded edges of this box gives a significant comfort when held in the hand and the buttons are very well thought about their positioning as well as that of the USB charging port.

This box also has a lock / unlock function.

Comptez environ cinq heures pour recharger la batterie via l’adaptateur mural 1A.
