Does the Steam Deck need exactly a 45W charger?

Steam Deck (both the LCD and OLED models) ships with and is designed around a 45W USB-C Power Delivery charger. That 45W is the target the hardware negotiates for, so a quality certified 45W PD charger fully charges the Deck at its intended speed. You don't need exactly 45W and nothing else, though — a higher-wattage charger (65W, 100W) works fine and gives extra headroom. What matters is that the charger supports USB-C PD; the Deck draws only what it needs.

Can I use any USB-C charger for the Steam Deck or Switch 2?

Mostly yes, for charging. Steam Deck and Nintendo Switch / Switch 2 all charge over USB-C Power Delivery, and a properly certified USB-C PD charger negotiates a safe voltage with the device. The catch is wattage: a weak or under-spec charger (for example a 5W–18W phone block) may charge slowly, and may not keep up if you're playing a demanding game at the same time — the battery can even drain while plugged in. For reliable charge-while-play, use a 45W charger or higher and avoid uncertified no-name bricks.

Will a 65W or 100W charger damage my Steam Deck or Switch 2?

No. USB-C Power Delivery uses a handshake (negotiation) between the charger and the device to agree on the voltage and current. The device requests only the power it's rated to accept — a Steam Deck asks for up to its ~45W limit even when plugged into a 65W or 100W charger, and the extra capacity simply goes unused. A higher-wattage PD charger is safe and actually useful because it leaves headroom for charging while gaming. The only real risk comes from uncertified chargers that ignore the PD spec.

How many watts does the Nintendo Switch 2 need to charge?

Nintendo Switch and Switch 2 charge over USB-C Power Delivery. The Switch 2 draws more power than the original Switch, especially when docked or playing demanding titles, but a 45W USB-C PD charger covers it comfortably — and a 65W charger gives extra margin. The official Switch dock and chargers use USB-C PD, so a quality third-party PD charger of 45W or more is a solid replacement or travel spare.

Can I charge my Steam Deck or Switch 2 while playing?

Yes, both are designed to be played while charging. The key is having enough wattage. A demanding game can push a Steam Deck to draw close to its 45W ceiling, so a 45W charger keeps the battery roughly level or charging slowly during play, while a 65W charger gives clear surplus so the battery actually climbs mid-session. An underpowered charger (under ~30W) may let the battery slowly drain even while plugged in during intense gameplay.

What wattage power bank do I need for handheld gaming?

For charging a Steam Deck or Switch 2 while you play, you want a USB-C PD power bank that outputs at least 30–45W on its USB-C port — lower-output banks may only slow the battery drain rather than refill it during demanding games. For capacity, 20,000mAh gives roughly one full Steam Deck recharge plus a partial top-up. Make sure the bank uses USB-C PD output (not just a basic 5V USB-A port), since that's what handhelds need for meaningful charging speed.

Does the Steam Deck or Switch 2 charge faster in the dock?

Charging speed is determined by the charger's wattage and the device's PD negotiation, not by whether you're docked or in handheld mode. A dock simply passes USB-C Power Delivery through to the device, so a 45W charger delivers the same charging power whether the handheld is docked or charging directly. What the dock adds is video output and extra ports — not faster charging. If anything, playing a demanding game while docked draws more power, leaving less surplus to charge.

Do I need a special USB-C cable to charge a Steam Deck at 45W?

For charging at 45W you need a USB-C cable rated to carry at least 3A (most quality USB-C charging cables are). Cables that support higher wattages (60W or 100W with an E-Marker chip) work too and add margin. Avoid thin, uncertified cables, which can bottleneck charging speed or cause heat. If you want the cable to also carry video to a dock or transfer data, you'll need a full-featured USB-C cable rather than a charge-only one.

Can one charger handle both my Steam Deck and my Switch 2?

Yes. Both devices charge over USB-C Power Delivery and each requests only the power it needs, so a single 45W or 65W PD charger handles both — just not necessarily at the same time on one port. A 65W charger is the safest single-charger pick because it has headroom for either device under load. If you want to charge both (or a handheld plus a controller) simultaneously, choose a 2-port USB-C PD charger and expect the wattage to split between ports.

Best Charger for Steam Deck & Switch 2 (2026)

Walter BartetUSB-C Research SpecialistUpdated June 202610 min read

Quick answer: The Steam Deck ships with — and is designed around — a 45W USB-C Power Delivery charger, and the Nintendo Switch / Switch 2 also charge over USB-C PD. For most people the Anker Nano 65W GaN II is the best single charger because its 20W of headroom lets the battery keep climbing even while you play. On a budget, the Belkin 45W PD 3.1 charger (~$13) exactly matches the Deck's spec. For gaming away from an outlet, add the Anker 20,000mAh USB-C power bank.

Will any USB-C charger work? Mostly yes — for charging. Both handhelds use standard USB-C Power Delivery, so a certified PD charger is safe. But a weak or under-spec charger may charge slowly and may not keep up while you're playing a demanding game; the battery can even drain while plugged in. We recommend 45W or higher and avoiding uncertified bricks.

What Steam Deck & Switch 2 Actually Need

Both the Steam Deck and the Nintendo Switch family charge over USB-C Power Delivery (PD) — the same open standard used by modern phones and laptops. That means the device and charger negotiate the right voltage automatically, and the device only ever pulls the power it's rated to accept. You don't need a proprietary brick.

The Key Facts

Steam Deck (LCD and OLED) ships with a 45W USB-C PD charger. A quality certified 45W PD charger fully charges it at the intended speed.
Switch and Switch 2 charge over USB-C PD too. Switch 2 draws more than the original Switch, but a 45W charger covers both comfortably.
Higher wattage is safe — and useful. A 65W or 100W PD charger won't damage either device (PD negotiation caps the draw) and leaves headroom for charging while you play.
Underpowered or uncertified chargers are the real risk. A weak brick may charge slowly or let the battery drain during demanding gameplay; uncertified chargers may ignore the PD spec entirely.

The practical takeaway: 45W is the floor, 65W is the comfortable sweet spot, and a USB-C PD power bank unlocks gaming away from the wall. The picks below cover each of those cases. Read more on why almost any USB-C PD charger works.

Pick 1

Best Value: Exact Steam Deck Wattage

If you just want a correctly-rated charger or a cheap spare, a certified 45W PD brick matches the Steam Deck's spec exactly. PD 3.1 with PPS lets the Deck negotiate a cleaner voltage curve, which means less heat while charging.

Pick 3

Best Multi-Device: Handheld + Controller Together

Handheld sessions rarely involve just one device — there's usually a controller or a phone that also needs charging. A 2-port USB-C charger powers both from a single wall plug, with the total wattage split across active ports.

BEST MULTI-DEVICE$18.52

Anker Nano 47W 2-Port Charger

47W total output shared across 2 USB-C ports
Charge a handheld plus a controller or phone from one wall plug
USB-C Power Delivery on both ports with smart power sharing
Compact GaN-class brick for travel kits
Single-port mode delivers enough for Steam Deck or Switch 2

Pros

+Two USB-C ports — charge the handheld and a controller/phone together
+Cuts the number of wall bricks you carry to a single plug
+Affordable (~$18) for a dual-port PD charger

Cons

−47W total is split when both ports are active — slower if charging two devices at once
−Not enough surplus to fast-charge two power-hungry devices simultaneously

Best for: Players who want to top off a handheld and a controller or phone at the same time from one outlet.

Who should skip: Anyone who only charges one device at a time and wants maximum single-device speed — a dedicated 65W single-port charger is faster for that one device.

Handheld gaming rarely happens in isolation — there's usually a controller, a phone, or a friend's device that also needs juice. The Anker Nano 47W splits across two USB-C ports so you can charge a Steam Deck and a controller together, or hit a single port at full speed when you only need one. It's the practical pick for couch co-op and travel.

Pick 4

Best for On-the-Go: Portable Gaming Power

The biggest limit on handheld gaming is the internal battery. A 20,000mAh USB-C PD power bank roughly doubles your runtime and outputs enough wattage to charge while you play — not just top off a sleeping device. It recharges over the same USB-C cable you already carry.

BEST FOR ON-THE-GO$47.49

Anker 20,000mAh USB-C Power Bank

20,000mAh capacity — roughly one full Steam Deck recharge plus a partial top-up
USB-C PD output high enough to charge handhelds while you play
Recharges over USB-C — same cable you already use for the Deck
Covers Nintendo Switch 2 for portable, dock-free sessions
TSA-friendly capacity for carry-on travel (verify carrier limits)

Pros

+Extends Steam Deck and Switch 2 play far beyond the internal battery
+Enough wattage to charge a handheld during active gameplay, not just when idle
+One bank tops off the handheld, a phone, and earbuds on a trip

Cons

−Heavier than a wall charger — it's a backpack item, not pocketable
−More expensive (~$70) than any of the wall chargers here

Best for: Travelers and commuters who want to play Steam Deck or Switch 2 away from an outlet for hours at a time.

Who should skip: Home players who always game near an outlet — a wall charger is lighter, cheaper, and faster for stationary use.

The biggest limit on handheld gaming is the internal battery — a Steam Deck or Switch 2 drains fast under demanding games. A 20,000mAh USB-C PD bank roughly doubles your runtime and, critically, outputs enough wattage to charge while you play rather than just topping off a sleeping device. It recharges over the same USB-C cable, so there's nothing extra to pack.

Summary

The Steam Deck (LCD and OLED) ships with and needs a 45W USB-C Power Delivery charger, and the Nintendo Switch / Switch 2 also charge over USB-C PD — with Switch 2 drawing more than the original Switch, which a 45W charger still covers comfortably. Almost any certified USB-C PD charger works safely because PD negotiation caps the draw, so a 65W or 100W charger won't damage either device; the real risk is weak or uncertified bricks that can't keep up while you play. Our picks: the Belkin 45W PD 3.1 charger (~$13) for the exact Steam Deck wattage at the lowest price; the Anker Nano 65W GaN II (~$30) as the best overall, with 20W of headroom for play-while-charging and enough output for Switch 2 and laptops; the Anker Nano 47W 2-Port (~$18) to charge a handheld plus a controller or phone together; and the Anker 20,000mAh USB-C power bank (~$70) for portable gaming away from an outlet. For charging while playing, use 45W or higher; a USB-C PD power bank should output at least 30–45W to refill rather than just slow the drain.
