Okay, the brand name you most likely never heard of, but it doesn’t matter. I love this:
Joguly Party Light, Stage Light ,Laser Light. It’s a Disco DJ Laser Light with RGB & UV LED, Remote Control, Sound Activated Strobe for Birthday, Family Party, Dance, Wedding, etc. With a built in rechargeable battery the laser light can operate for 6~7 hours. (Both led and laser lights for 6 hours, only led shinning or laser lighting for 7 hours). Now the company says you can take the party light and have a party anytime. I’ll add, and anywhere. In the video you’ll see the result when I took my Party Light down to Riverside Park. There are 128 patterns according to the company. I didn’t count them, but I’m impressed! And it only uses 6 watts. Comes with a 
USB cable with a pin connector into the back of the party light. It says “AC adpater”, but there wasn’t one with my unit. Didn’t matter, I have a bunch of those AC to USB plugs around Gizneyland. Battery capacity: 4400mAh. Charging time: 4-6 hours. Working time: 6-7 hours. Play modes: auto play, voice control and remote control. The remote control also has a built in timer. I paid $45.99 and it was still that price on 2/12/22, but it could change at any time. Also note this from the website: WARNING: Be careful not to look directly at the laser aperture to avoid eye injury.
