Hooking up your Nintendo Switch to play on the big screen is a cinch. But getting the best performance requires the right accessories and power setup. Below I‘ll cover everything you need to know about powering the Switch for TV gaming as an electronics expert and gaming enthusiast.
The Switch Dock: HDMI & Power Delivery
The included Switch dock has two essential connections on the back:
- HDMI out port to send video to your TV
- USB-C power input for the AC adapter
Both cables must be connected for the dock to output gameplay footage over HDMI. Here‘s why both are required:
HDMI Out: This port sends uncompressed digital video to your TV at up to 1080p resolution when docked. The Switch has a custom video output chip that handles HDMI signal conversion.
AC Adapter: The AC power connects to a USB-C port on the dock to deliver electricity. This powers the dock‘s internal circuitry and enables video output.
Without power supplied to the dock, the HDMI video signal cannot be transmitted. The USB-C power input provides up to 39 watts to run the dock‘s components and charge the Switch itself.

Always use the included Nintendo power adapter with the dock, as lower wattage adapters may not properly power HDMI output.
Battery Not Required for TV Play
An interesting fact about the Switch is that the console‘s battery does not need any charge to play games on your TV.
As long as the Switch is docked and the dock has power connected, gameplay is output over HDMI to your television even if the Switch is fully dead!
This is because the dock provides electricity directly to the Switch‘s internals once connected. No battery power is required – the dock powers the CPU, GPU, and other components needed for TV output.
So feel free to drain your Switch battery completely in handheld mode, then dock it for big screen gaming while it recharges.
Switch vs. Other Consoles: Battery Life
Compared to other current generation consoles, the Switch offers decent but not exceptional battery life. Here‘s how it compares:
Nintendo Switch – 4.5 to 9 hours
PlayStation 5 – 10+ hours
Xbox Series X – 8+ hours
Factors like screen brightness, WiFi/Bluetooth usage, and game complexity affect actual battery runtime. But the Switch clearly has the shortest average lifespan per charge versus the competition.
Frequent gaming on the go may require packing the Switch AC adapter to recharge at outlets. Console rivals like the PS5 offer longer lasting batteries ideal for travel.
USB Power Delivery & the Switch
The Switch utilizes USB-C for both data transfer and power delivery. But it does not fully support the USB Power Delivery (USB-PD) specification.
USB-PD enables power draw up to 100 watts at variable voltages from 5 to 20V. This allows fast charging of laptops, tablets, and other USB-C devices.
The Switch limits power input to 39 watts max at 15V / 2.6A. Charging voltage cannot be adjusted via USB-PD – only the Nintendo Switch AC adapter will charge the console at maximum speed.
Using third party chargers with mismatched voltages or amperage can potentially damage the Switch by overloading circuits. Sticking to Nintendo‘s official charger avoids any USB-PD confusion.
Are Third Party Docks Safe to Use?
While generic USB-C hubs can sometimes output Switch video to a TV, using an unlicensed third party dock comes with risks.
In 2018, many Switch consoles were "bricked" – rendered permanently inoperable – by using a third party dock. Unofficial docks can overload or underpower the Switch, damaging internals.
Even licensed docks from Hori and others have compatibility issues resulting in failed HDMI output or power problems. This is because Nintendo uses a non-standard USB-C implementation.
The safest choice is to only use the Switch dock included with your system. While its bulky size is inconvenient, no other dock replicates the proprietary power delivery and video output required.
HDMI Cable Recommendations
Don‘t waste money on premium HDMI cables for your Switch! Standard High Speed HDMI cables support resolutions up to 1080p and bandwidth up to 10.2 Gbit/s – far beyond what the Switch can output.
Features like Ethernet and Audio Return Channel (ARC) are also unnecessary for Switch connectivity. Here are some economical choices:
- AmazonBasics – $7.50 (6 feet)
- UGREEN – $8.59 (3 feet)
- Cable Matters – $7.99 (10 feet)
Avoid cables over 10 feet unless active/powered. And don‘t fall for misleading marketing using terms like "gold plated" or "240Hz" – plain HDMI cables work perfectly with the Switch on any HDTV.
Global TV Market Trends
As television upgrade cycles continue globally, legacy analog inputs are disappearing:
According to Statista, HDMI has grown from 17% market share of TV inputs in 2010 to an estimated 89% in 2022. Analog inputs like component/composite comprise less than 2% currently.
This means the Switch releasing without analog AV output in 2017 was well timed with HDMI‘s dominance. Nintendo‘s choice of HDMI-only output matched rapid market changes.
Preserving Your Switch Battery
Like all lithium-ion batteries, the Switch‘s capacity will degrade over years of use. You can optimize longevity by:
- Avoid playing at full brightness
- Turn off WiFi/Bluetooth when not needed
- Disable vibration
- Let battery discharge ~50% before recharging
- Avoid exposing Switch to high temperatures
Research from Battery University shows lithium-ion capacity loss of around 2% per year. Following these usage tips can maintain over 70% of original capacity after 5 years.
How Light Switches Work
Flipping a light switch breaks the connection supplying electricity through a circuit:
Inside the switch, metal contacts connect the hot wire path when toggled on. In the off position, the circuit is interrupted stopping flow before outlets and lights wired later in the circuit.
This permits placing a switch anywhere along a circuit to control additional downstream connections. Need a new overhead light? Running a switch loop allows controlling the light from any outlet box on that circuit.
Helpful Home Electrical Safety Tips
When wiring switches, outlets, and fixtures in your home, follow these guidelines to stay safe:
- Turn off the circuit breaker before doing any work
- Verify power is off with a non-contact tester
- Only modify and repair wiring you installed or are qualified for
- Avoid overloading circuits with high-draw devices like heaters or air conditioners
- Periodic inspections of wiring condition can identify damage before failures occur
Adhering to local electrical codes and using GFCI outlets near water sources are also highly recommended for protecting your home and family.
I hope this comprehensive guide better explains how to power your Nintendo Switch for the best TV gaming experience. Let me know if you have any other questions!
