Basic Question -- Powering a small plasma ball with a battery

[Dargeth]

HI, I have embarked on a small project basically it is for my daughters dance routine prop.
I was wondering if I could power a small plasma ball with a battery.
The plasma ball power supply specs are: Output: DC 12V 350mA MAX 4.2W
It has to be mobile it will sit on a small table which has to be moved on and of the stage where she will dance.
Thanks.

Keep it simple. Get an USB powerbank with 2A output, and one USB DC booster cable for 12V, with at least 0.5A output.

Or use 8 flashlight batteries in series. Penlight, size "AA", Alkalines should last at least half an hour. "D" size should be good for at least 4 hours. Of course this approach requires either finding battery holders or soldering to the batteries, which you may not want to do.

Whatever approach you use, be sure to get the "+" and "-" polarity correct to the globe, it probably does not have internal protection for reverse polarity.

Could you hide two of these under the table ?
