For a Nintendo Switch 2 in handheld mode, look for a USB-C Power Delivery (PD) power bank that outputs at least 30W. Anker recommends 45W or more. Docked mode is different: Nintendo says a replacement AC adapter for the dock should supply at least 54W, and its page says nothing about power banks. A cheap 18W bank may charge the console slowly, or lose ground while you play.
If a Switch 2 is on someone’s holiday list, this is a good thing to check before the trip. We haven’t tested any power bank with the Switch 2. This guide pulls together Nintendo’s support page, news coverage, Anker’s blog and user reports, and labels each one.
What Nintendo Actually Says
Nintendo’s support page covers the dock’s AC adapter and says:
- The Switch 2 AC adapter (model NGN-01) is the recommended adapter for the dock.
- Another adapter and cable can be used “if the power output is at least 54W.”
- The original Switch adapter (HAC-002) can charge the console when plugged in directly, but “can not provide enough power to be used with the dock.”
The page doesn’t mention power banks, USB Power Delivery or handheld mode. So everything about power banks below comes from other sources.
Handheld vs. Docked: The Rule
| Handheld (on the go) | Docked (TV mode) | |
|---|---|---|
| What you’re powering | The console directly | The dock, which then powers the console |
| Nintendo’s guidance | Doesn’t say | Replacement adapter should supply 54W or more |
| What we found | Reports of 20W to 45W working | No report of a power bank running the dock |
| Our take | Choose a PD bank of 30W or more | Use the official adapter at home |

How Much Power Does It Need?
SlashGear (November 2025) reports Nintendo’s figures: the console draws about 19W while gaming in TV mode and 8W on the home screen. In handheld mode, it says the draw is roughly half of that, though Nintendo doesn’t publish exact numbers. SlashGear adds that Nintendo says the first Switch’s 39W adapter can charge the Switch 2 in handheld mode, and suggests 30W for handheld and 54W or more for docked. Its handheld numbers lean on Reddit reports, not official data.
Anker’s blog, a manufacturer page, recommends a PD power bank of at least 45W and warns that with too little power “the battery may still drain slowly even while plugged in.” Anker also says its recommendation could change with final console specs, so treat it as general guidance.
What Users Report
From a Reddit power and charging thread soon after the Switch 2 launched:
- One user played Pokémon Scarlet in handheld mode on an Anker 30W charger and went from 51% to about 90% at half brightness.
- One estimated the handheld draw at around 15W and said a 22.5W battery bank charged “slowly” while playing.
- One said a 20W iPad charger worked but seemed to take a while.
- One said an INIU 45W power bank “has been perfect.”
- Another user reported no battery drain while docked on a 67W Torras charger. That’s a wall charger, not a power bank.
These are individual posts, not tests, and the thread had unanswered questions about whether airline outlets limit power.
Can a Power Bank Run the Dock?
We couldn’t find a confirmed report. A power bank that can output 60W over USB-C would meet the 54W number on paper, but Nintendo’s page is about AC adapters, and we found no user confirming it works. For travel with a hotel TV, a power bank may not be the right tool. The official adapter is. If you do try it, test it at home first.
How Many Refills Can You Expect?
Here’s the math, as an illustration and not a promise. Anker’s FAQ gives the Switch 2’s battery as around 5,220 mAh. At 3.7V that’s about 19.3 Wh (5.22 Ah × 3.7V, our arithmetic). A 20,000 mAh power bank holds about 74 Wh by the same method. Power banks lose energy as heat and in voltage conversion, so if about 70% is usable, you’d get roughly 52 Wh, or around 2.7 full refills from empty. Anker says a 20,000 mAh bank is “usually enough for several full charges.” Our estimate uses an assumed efficiency, so your numbers will vary. We don’t repeat the claim of “4 to 6 charges” from a user, because it was unconfirmed. Our power bank decision guide explains the Wh math.
What to Look For
| Check | Why |
|---|---|
| USB-C PD output of 30W or more | Handheld reports suggest 20W is slow and 30W to 45W works |
| A listed output on the USB-C port, not just the total | Multi-port banks often split power between ports |
| A USB-C to USB-C cable rated for the same power | Anker advises certified PD cables; avoid cheap unbranded ones |
| A bank that doesn’t auto-shut off | Heavy draws are rarely a problem, but test it |
| Capacity of 10,000 mAh or more | A 10,000 mAh bank is only around one refill by the math above |
A 10-Minute Test Before You Travel
- Charge the console to about 50%.
- Plug in the power bank with the cable you’ll travel with.
- Play a demanding game for ten minutes in handheld mode.
- Check the battery. If it goes up, the bank keeps pace. If it falls, you need more watts.
- Repeat with the screen at the brightness you normally use.
