1000W 16-Port USB-C Charging Cart for School Computer Labs
A 16-port USB-C charging cart built for computer labs: 1000 W of total charging power, PD output up to 20 V/5 A, staggered power sequencing, lockable metal storage for sixteen laptops and a place for the classroom Wi-Fi access point.
Key takeaways
- One cart replaces sixteen wall adapters and outlets — charging, storage, security and mobility in a single unit.
- 1000 W is a total budget shared across sixteen USB-C bays, not a per-port rating; size your deployment against the total.
- A power sequencer staggers the start of charging so a full cart does not trip the circuit breaker.
- A residual-current breaker, surge protector, charging timer and EN 62368 electrical safety underpin the design.
- The cart can also house the classroom Wi-Fi access point and presents an RJ45 port on the facade.
Schools running a laptop or Chromebook fleet need more than a row of power adapters. A charging solution that works in practice has to combine five things in one system: charging, organised storage, security, mobility and electrical load management.
The LVSUN M-C16S is a 16-port USB-C charging cart built for computer labs and other managed laptop environments. With up to 1000 W of total charging power, it lets a school charge, store and move sixteen devices as a single unit rather than as sixteen separate problems.
Centralised USB-C charging
Every bay charges over USB-C Power Delivery. The cart outputs DC 5 V, 9 V, 12 V, 15 V/3 A and 20 V/5 A and supports PD 3.0 and QC 4+, so a compatible laptop can draw up to 100 W. Input is AC 100–240 V, 12 A, 50/60 Hz, and a 5-metre IEC power cord is included.
An integrated power sequencer staggers the start of charging across the bays. Bringing a full cart online therefore does not present the electrical installation with a single large inrush, which is what trips a breaker in a classroom that was never wired for sixteen simultaneous chargers.
Electrical safety
The electrical system carries a residual-current circuit breaker, an internal surge protector and a charging timer. The cart is built to the EN 62368 electrical safety standard and is rated for operation from 5 °C to 45 °C at up to 80% relative humidity.
Secure storage and easy mobility
Two independent compartments separate the devices from the electronics — a front storage area for the laptops, and a rear technical area behind its own door. Inside the storage area:
- One sliding, secure drawer for the teacher’s laptop
- Fifteen drawers for student laptops, each with a mouse compartment
- A projector stand
- Cable routing and storage arranged so leads stay tidy between sessions
A key lock secures the cart against theft while it is parked or moved between classrooms. The structure is reinforced metal, and a retention system holds the integrated equipment in place during transport. Four professional casters — two of them braked — together with an operating handle make the cart easy to move across uneven floors.
A ventilation system cools the cart while it is closed and the laptops are charging, so devices are not left to heat each other in a sealed cabinet. The cart measures 1150 × 700 × 930 mm and is finished in black.
Network and classroom infrastructure
The cart can carry classroom network equipment as well as charge devices. A Wi-Fi access point mounts inside the rear panels, an RJ45 port is presented on the facade, and a 5-metre Cat 6 UTP cable is supplied. Dual on/off switches, each with an indicator light, control the Wi-Fi access point and laptop charging independently — so the access point can stay up overnight while charging runs on its own timer.

What to check before you buy
Whichever cart you choose, work through the same list before committing to a deployment:
- The number and type of devices to be charged
- USB-C charging requirements, including the wattage each device actually needs
- Total available charging power, and how it is shared
- The physical dimensions of the devices, so they fit the bays
- Storage and security requirements
- Mobility — floor surfaces, doorways and lift access
- Ventilation while charging
- Network-management requirements
The M-C16S brings these functions together in one 16-device platform for schools that want a single, centralised approach to laptop charging and storage. Where a project needs a different device count, charging power, cabinet size or custom functions, LVSUN builds charging-cart configurations to the deployment’s requirements.

Sources & evidence
All technical values are taken from the internal LVSUN M-C16S specification sheet ("", Technical Specifications). The specification document itself is not published. Total power, port count, input/output, dimensions, protection devices, EN 62368, operating environment, caster and compartment counts and supplied accessories are stated in that sheet; no value has been inferred.
