Simeiyue Smy90 Box Mod Review

In this Smy 90w review we’ll discuss what is new and unique with the newest mod from Simeiyue.

While you may be familiar with the GOD from Simeiyue, this is a more subdued yet powerful mod that gives you an output of up to 90 watts, which is quite impressive.

An excellent feature that the Smy90 has is the temperature protection feature.

Simeiyue Smy90 | | Only $73.84!

Simeiyue SMY90 (1)This particular function will shut the device off should it get too hot.

This is good if it accidentally fires in your pocket/purse, as it will keep your mod safe.

You can adjust the output from 5 to 90 watts using the two adjustment buttons on the side of the device below the LED screen and firing switch.

Sub-ohmers will enjoy the SMY 90 because it’s capable of firing atomizers as low as 0.1ohms.

It’s powered by a single 18650 battery that can be recharged via the micro USB port.

One thing that is unique about this device is the ability to go to 90W on one 18650.

All of this is housed in an awesome looking case that is stylish and slick with your choice of colors.

Gripes & Concerns
