No, 18 W per port (PD 3.0) is not sufficient to reliably charge Surface Pro 7 devices overnight.
The Surface Pro 7 normally ships with a ~60–65 W charger. For USB-C charging, Microsoft recommends at least 45 W, and 60 W is ideal.

The school has received a donation of Surface 7 Pro laptops. Looking at a Storage and Charging Trolley. Trolley available from a local supplier supports PD 3 charging, 18W per port. Will that be sufficient for charging the devices overnight.
Thanks for any assistance or guidance.

2026-02-07T13:30:43.22+00:00 Thanks S. Sengupta for your response. Your suggestion of minimum 45W USB-C is very helpful. I have seen a well known Swedish Home Furnishings and Inspiration store offer 45W chargers for a very reasonable price, don’t think I can mention any registered names on this forum. Another option for an additional €10 is another Global company offer their own Basic 65W charger. Would the 65W be a better option?

The Surface Pro 7 supports USB-C charging, but it is recommended to use a power supply that provides at least 65W for optimal charging performance. The charging trolley you mentioned, which supports PD 3 charging at 18W per port, may not provide sufficient power for charging the Surface Pro 7 effectively, especially if multiple devices are being charged simultaneously. Therefore, it is advisable to consider a charging solution that can provide higher wattage per port to ensure the devices charge overnight without issues.
