Can 16 Laptops Charge at 65W Simultaneously?
The arithmetic is simple; the electrical reality is the real answer.

Key takeaways
- 16 × 65W = 1040W device draw, before efficiency losses
- Simultaneous full-power depends on station rating + circuit + product design
The arithmetic
16 laptops at 65W is 1040W of device-side demand. Add power-conversion overhead and the supply must provide meaningfully more than 1040W to sustain it.
The real constraints
- The station must be rated to deliver that total output continuously
- The branch circuit must supply it (see the NEC 80% continuous-load rule)
- Many systems share power dynamically, so 65W to every port at once is only possible if the product is explicitly sized for it
So "yes, if" — yes when the station’s rated total output and the circuit both support ~1040W-plus continuously and the product supports full simultaneous per-port output. Confirm all three per product and per site.
Simultaneous 65W feasibility
Frequently asked questions
Is 1040W the number I need?
That is device demand; the supply must exceed it to cover conversion losses and stay within circuit limits.
Will every laptop really get 65W?
Only if the station supports full simultaneous per-port output and the circuit allows it — otherwise power is shared.
