Overview: Sigelei 150

A few disclaimers to start with: this is NOT a review. We are not testing this device for output voltage or wattage. There is a significant risk in using multi-battery systems. If you consider using one of these devices, you have to be aware that you are taking high risks, putting high voltage to a coil that is near your face and pointed directly at your throat. We do not recommending using these devices at extremes of low or high wattage.

The Sigelei 150 is shown at the right with the included silicone wrap. The silicone wrap, to the best of our knowledge, is available only in black, although the Sigelei 150 is available in either black or silver.

The buttons (as shown) are color matched to the unit, and are flat.

The Silelei 150 cover is held in place with a total of eight magnets. The cover is held in place firmly and can be liften off with a nail style slow at the bottom to lift it off.

I was really impressed with the quality of construction of the device, both inside and out. Inside there are no visible assembly artifacts (glue, etc.) and there is a built-in ribbon for the battery insertions and removal.

The finish is quite nice with beveled edges all around. On the black unit I received, the beveled edges are a brushed aluminum ... a nice contrast to the black finish of the rest of the unit.

The top is designed for RTA and RDA atomizers that have air flow through the sides. The bottom is flush and does not really have any air flow channels for atomizers with air flow through the 510 connector. I was also very pleased to see that the 510 connector is floating – it is spring loaded and either brass or gold plated.

The display on the unit is not like most other advanced personal vaporizers. This is a distinctly different design showing four quadrants in a box. The upper left is for the wattage display (10.0 watts to 150.0 watts ... increments are 0.1 from 10.0 to 50.0 watts, 1 watt increments from 50 to 150 watts). The upper right is for the voltage display (that is the voltage output from your wattage selection). The lower left is for a graphical representation of the remaining battery charge (with a textual percentage to the right of that graphical display). And, the lower right is for your coil resistance.

Of the many devices we have looked at and tested, the Sigelei is among the most accurate for its wattage and voltage setting. It also detects coil resistance accurately to a one decimal precision.

Sigelei is about the only company that we are aware of that supply a silicone wrap with the unit – it's not an option, it's included in the box.

You should note that the Sigelei 150 can only be charged by removing the batteries from the case and using an external battery charger.

So, what's the verdict? Is it worth it? Clearly, no – this is not a device for anyone that does not have intimate knowledge of technology and the risks associated. The advantages of having multiple batteries for the average vaper are strictly in use time between charges. In this regard, all multi-battery systems will deliver extended vaping time. But the ranges of output power are too extreme and put these devices in a risk category that is awfully hard to ignore. Use at your own risk. If you are considering using a mechanical device with multiple batteries, the Sigelei 150 is a much much safer alternative and you at least get protection from the step-down converter limiting voltage to the coil.
