The MARSDOCK 45W Charger is a third-party AC adapter for the Nintendo Switch, with 15V/2.6A output that matches the spec of the original Nintendo dock. The charger supports TV mode through the Switch dock, plus handheld charging on the Switch OLED, Switch Lite, and Steam Deck. A 5-foot USB-C cable also comes included, longer than the original Nintendo cord. The universal 100-240V input handles international voltages if you travel abroad. Built-in safety features include protection against overcharging, short circuits, and overheating.
A secondary charger for your Switch that keeps your console juiced up
TV Mode compatibility is the main reason to consider a third-party Switch charger over a generic USB-C wall plug. Most USB-C chargers don’t deliver the 15V/2.6A output that the Switch dock needs to power the system in docked mode, which is why off-brand chargers can fail to register at all or run the dock at a lower TV resolution. The MARSDOCK 45W charger matches Nintendo’s official spec, so your Switch displays at full resolution on a TV without flickering or disconnecting mid-game.
Steam Deck owners can also use the same charger, since both systems support the 15V USB-C charging spec. The MARSDOCK 45W works with both the Steam Deck dock and the handheld unit. Plus, the same adapter also charges your Switch Pro Controller, Switch Joy-Cons, and most other USB-C devices that draw 45W or less. So one wall plug handles a multi-console household with both Switch and Steam Deck owners.
The 5-foot USB-C cable is twice as long as the original Nintendo Switch cable, which makes the charger more practical for couch gaming or charging while playing handheld across a room. A 10-foot version is also available on the same MARSDOCK listing if you want extra length for charging across a bedroom or living room. The universal 100-240V input also lets the charger work in Europe, Asia, and other regions with a standard plug adapter.
Built-in protection circuitry handles overcurrent, overcharging, short circuits, and overheating, so your Switch isn’t at risk during overnight charging or a long session. The charger also includes a thermal monitoring system that throttles down if the temperature climbs too high during extended use. The MARSDOCK is a third-party charger, so it’s not officially licensed by Nintendo, but it carries CE, FCC, and RoHS certifications that confirm compliance with basic safety standards.
If you’ve ever needed a backup charger for the Switch or a second one to keep at the office, the MARSDOCK 45W is a much cheaper path than buying Nintendo’s official replacement. At $12, down from $17, the MARSDOCK comes in well under the $30 official charger while supporting the same TV mode through the dock. You can also use it on a Steam Deck or for charging Pro Controllers when your Switch is unplugged.
