Tesserack

Meet the "Tessarack". An industry-first, all-in-one, self-sustaining, battery-operated cart that can power a marching show.
 
Q&A
How long does it last? Up to 20 hours at max power capacity! For tech nerds, that's 20 hours at a constant 15 amp usage...which is unlikely to happen.
​
How does it recharge? ​
Sunlight and an AC outlet. Use UV during the day and AC at night.​
​
How long does it take to recharge? ​
When it's plugged into an outlet, only a few hours! If plugged in overnight , it will be ready for a fullday of rehearsal.​
​
What if it starts raining during use? ​
The top of the cart is water-resistant, but don't take it "dancing in the rain".
