A travel charger sounds simple until a Steam Deck or Nintendo Switch starts charging slowly, refusing TV mode, or warming up in ways that make the whole setup feel cheap. Many buyers grab the first USB-C charger they already own, but handheld gaming hardware is far less forgiving than a phone when the voltage profile is wrong.
Why 45W is the practical target
For mixed Switch and Steam Deck users, 45W is the easiest wattage tier to understand and buy with confidence. It covers normal handheld charging, gives docks a better chance to behave correctly, and avoids the underpowered feel of random phone adapters.
| Power tier | Typical result | Who it suits |
|---|---|---|
| 30W and below | Can feel slow or inconsistent for docked play and larger handheld batteries. | Emergency backup use only. |
| 45W | A more reliable middle ground for Switch, OLED, Lite, and Steam Deck travel kits. | Most gaming-accessory buyers. |
| 65W+ | More headroom, but often overkill if the charger is only for handheld gaming devices. | Users charging laptops and handhelds from one brick. |
TV mode and dock behavior
The biggest buying mistake is assuming every USB-C charger that powers a phone will also support a gaming dock correctly. Switch and Steam Deck setups benefit from chargers that actually advertise the right 15V output. That is where the MARSDOCK 45W USB-C Charger makes more sense than improvised leftovers from a drawer.
Cable length affects daily use
A charger can have enough wattage and still be annoying if the cable is too short for bedside play, sofa charging, or a standing dock. A fixed 5-foot cable is not glamorous, but it is one of the reasons a second charger can feel dramatically more useful in real life.
When this charger is the better buy
- You want one travel charger for Switch and Steam Deck instead of moving the original adapter constantly.
- You need a dock-side backup that is more trustworthy than a basic phone brick.
- You are building out a portable setup around the JSAUX ModCase and want the power side to be just as practical as the case.
