Holiday travel means dead time. Dead time means a handheld on low battery by the time you land or pull into the driveway. You need one power bank that charges fast and doesn’t catch fire in your bag.
That last part matters more than people think. Power banks are lithium batteries. A bad one is a safety problem, not just a dead-gear problem. That’s why this list has exactly one pick, and it’s from a brand with public certification paperwork to back it up.
The pick: Anker Power Bank (20K, 87W, Built-In USB-C Cable), model A1383.
It’s fast enough for either handheld, big enough to cover a long travel day, and it’s one of the few in this category where you can actually go look up the safety documentation yourself.
Why Certification Isn’t Optional Here
A power bank isn’t like a cheap controller or a mouse pad. If it’s wrong, it can fail badly. Lithium battery packs that skip proper engineering and testing are the ones that show up in news stories about overheating bags.
That’s why this list only considers power banks from established makers who publish real certification, not just a sticker on the box. For the A1383, Anker publishes an EU Declaration of Conformity, which means the product has documented testing behind it rather than just a brand name you recognize.
It’s also worth being straight about the flip side: Anker recalled several power bank models in 2025 under CPSC oversight, covering models A1263, A1257, A1647, A1652, A1681, and A1689. The A1383 recommended here was not part of that recall. A recall, publicly handled through the CPSC, is actually a sign the system is working. It beats a no-name brand that never tests or reports anything.
Why 65W Is the Right Number to Look For
Here’s the simple version: more watts means faster charging, up to a point where the device itself caps it.
- Steam Deck ships with a 45W USB-C PD charger from Valve. A power bank that can push 65W to a single device has plenty of headroom to charge it at full speed.
- Switch 2 charges over USB-C as well. Nintendo hasn’t published a charging wattage for it, but it’s a USB-C PD device, so a 65W-capable power bank comfortably covers it too.
The A1383 can deliver up to 65W to one device from either its built-in USB-C cable or its USB-C port, and up to 87W total if you’re charging multiple things at once (say, the handheld plus your phone). That’s not overkill, it’s just enough margin that you’re never the bottleneck.
Will It Actually Get You Through a Travel Day?
Here’s the battery math on each handheld, straight from the manufacturers:
- Switch 2: 5220mAh battery, rated for about 2 to 6.5 hours of play depending on the game.
- Steam Deck: 50Whr battery, rated for about 3 to 12 hours depending on the game.
A 20,000mAh power bank is a meaningfully bigger battery than what’s inside either handheld. Exactly how many extra hours of play you get varies a lot by game, screen brightness, and how warm the cabin or car is, so we won’t throw out a specific recharge count. What we can say: it’s built to carry you well past a single depleted handheld, with enough left to top off a phone too.
One more travel-day perk: the built-in USB-C cable. No more digging through a bag for the one cable that didn’t fry itself. Anker rates that built-in cable for over 10,000 bends, which matters when it’s getting shoved in and out of a backpack pocket for a week straight. And if you do end up near an outlet, a 65W charger gets the bank itself back to full in about 1.5 hours, fast enough to top off during a layover or a rest stop.
The TSA and FAA Rule You Cannot Skip
Spare lithium batteries, including power banks, go in your carry-on only. The FAA is explicit about this: they are not allowed in checked luggage.
That matters more at the holidays because of gate-checked bags. If your carry-on gets tagged for gate-checking because the flight is full, you need to pull the power bank (and any spare batteries) out and keep them with you in the cabin. Build that into your pre-boarding routine now, not when you’re juggling a diaper bag and a boarding pass at the gate.
Who This Pick Is For
This is the single pick here, not one of two tiers, because the safety requirement narrows the field hard. If you’re bringing a Switch 2 or Steam Deck on a holiday trip, you want:
- Enough capacity to matter (20,000mAh clears that bar)
- Enough wattage to charge fast, not trickle (65W single-device, 87W total)
- A built-in cable so you have one less thing to lose
- Documented certification you can actually verify
The A1383 checks all four boxes. If you’re also picking gear for the handheld itself before the trip, our guide to Switch 2 accessories worth buying and the breakdown of Steam Deck vs Switch 2 for short play windows are good next stops.
