25cm Arc Bluetooth Square Wave PCB Musical Tesla Coil Scientific Experiment Toy- US PlugFeatures:
.Desktop integrated mini solid-state Tesla coil finished product, the primary and secondary are made of PCB. It is a change from the traditional solenoid secondary Tesla coil, which is highly integrated and more clean and safe.
.The Tesla coil power supply is only 48-54V DC, and the low-voltage power supply ensures safety, and the effect is stronger than most desktop-grade commercial half-bridge Tesla coils on the market. The 2M high frequency sub-level, there is no pain even if you touch the arc with your hands.
.The 2 in 1 Tesla coil has both a toroidal coil and a coil head integrated with 6 discharge needles. Plug in the power supply and you can experience the charm of lightning in the palm.
.Bluetooth connection can play square wave music, increasing its playability. At low frequencies, you can freely play the arc between your palms. The frequency of the music mode is higher. When the arc is concentrated at one point, there will be a burning sensation.
.The power supply is a DC power adapter, no need to be grounded, it is more stable, the heat sink has a temperature control switch, the power supply has over-current protection, the pulse width of the music mode is limited, and multiple protections. There is no fan to dissipate heat (because the heat is very low), do not run at maximum power for too long, so as to avoid the temperature control protection is too fast.
.Instructions for Use: Switch down to fixed frequency mode, the knob to adjust the arc frequency and size, pause in the middle of the switch, switch up to music mode, use the audio cable to link the phone to the maximum playback, the knob can adjust the size, the right knob Control the size of the arc and twist the clockwise pointer. The left knob controls the fixed frequency frequency, and clockwise speeds up the arc spray frequency. It is best not to open the maximum arc in music mode all the time, so as to avoid the temperature control protection is too fast. If the arc in the music mode is turned to the maximum and sometimes discontinuous, this is caused by excessive power supply protection. At this time, a small arc should be opened appropriately.
.Very good science and intelligence gifts.

Feels cheap, not good for old eyes.
The watch seemed to work good. But it felt cheap, and I was looking for something with better illumination and easier to read. I ended up returning it.

Impressive, especially at this price point.
Color: black/black
Feels & looks like a Timex Expedition- which fills with water in the shower, fogs on himid days.
This is a fraction of the cost and functions as advertised.

Such an amazing watch
Color: silver/black
Beautiful look, no noise. The brightness on the glow and the dark portions are amazing during the night. It feels like a hundred dollar watch while being so cheap and affordable. Lightweight and easy to wear. I’ve done a lot of hard work with this watch and there isn’t a scratch on it.
