What this charger delivers

The MARSDOCK STM45 is a 45W USB-C power adapter with a fixed 5ft cable that supplies 15V at 2.6A for fast charging. It also provides a 5V 3A rail for broader device support. The unit accepts 100-240V input at 50-60Hz and includes a 5ft AC extension cord. Built-in safeguards protect against overcharging, short circuits, overheating and sparking.

Who it suits and who it does not

This charger suits Nintendo Switch, Switch OLED, Switch Lite and Steam Deck owners who need reliable TV-mode dock power and a long cable for comfortable play. It also suits users of other USB-C devices that draw up to 45W. Buyers whose devices require more than 45W or a voltage profile not listed here should look at a higher-output adapter.

Capacity and headroom

At 45W the adapter comfortably charges a Switch from 0% to 50% in an hour and powers TV-mode docks without voltage sag. The 15V 2.6A output covers most handheld consoles and tablets rated for 45W USB-C charging. Devices that negotiate more than 45W or demand a different fixed voltage will not reach full speed on this unit.

Questions about this item

What type of wall socket does the MARSDOCK STM45 plug into?

The adapter accepts 100 to 240 volts at 50 or 60 hertz, so it works with standard household outlets worldwide.

Will the 15V 2.6A output run a Nintendo Switch dock in TV mode while I keep using my older 39W charger for handheld play?

Yes, the 45W brick delivers the 15 volt 2.6 amp profile the dock needs for TV mode, and the older 39W unit can still charge the console in handheld mode.

How can I confirm the charger is delivering the full 45W to my Steam Deck after I plug it in?

The Steam Deck's battery settings screen shows the incoming voltage and amperage; look for 15 volts at up to 2.6 amps to verify full 45W operation.
