The plasma ball is processed very cheap. The glass is very thin and zerkratz quickly.
The plastic foot is far too easy.
The switch is ebendfalls the Cheapest what's available on the market.
The supplied AC adapter is designed much too weak to 650mA and heats up quickly.
Have a power measurement performed and determined that the ball consumes 10 to 14 watts, depending on whether one touches the ball or not.
So the ball moves at an average of about 12V 1000mA which means that the power supply is constantly stressed.
The field strength around the globe herrum is immense. After Microwave the largest emitters Wöhl in the apartment. Only in the microwave radiation is shielded. Not here. So full carrot electrosmog!
But ......
The price / performance-Verhälniss is denoch good one gets an absolutely impressive toy with the Nikola Tesla already has studied electric fields. Fluorescent lights when in the vicinity of the ball comes etc .....
In addition, you may save a freshener with Ion conditioning since the Betieb the plasma ball a bit of ozone is produced.
Am absolutely fascinated but maybe next time I give a little more money on a better quality.
But now I Holle me first a better power supply which alone costs about 8-10. So you should at the price not too bad rate. A little tip: Have treated with car polish which forms a thin polymer layer and protects the glass from minor scratches the ball.
Conclusion: I'm happy!
