The Steam Deck's battery life is solid, but it does vary wildly depending on the game you're playing. The last thing you want is for your Steam Deck to suddenly run out of juice, especially when you're traveling. That's where a power bank comes in handy to help you keep gaming on the go.

INIU

Despite its budget-friendly price, the INIU Portable Charger is surprisingly rich in features. Thanks to its dimensions and performance, it’s one of the best solutions for topping off your Steam Deck if you have no interest in lugging around a massive battery.

With the INIU Portable Charger being a 45W power bank, it’s already fully capable of charging the Steam Deck, even while you’re playing. In fact, given its 55.5Wh capacity, it’s essentially like having a second, fully charged Steam Deck battery. It doesn’t take long to recharge, either.

As dimensions go, the INIU Portable Charger certainly does its name justice. It’s slightly thicker than a smartphone, but its length is much shorter. You’ll have no problem slipping it into a purse, travel bag, or your pocket. In fact, having both a USB-C and USB-A port means it’s just as useful for charging other devices like your smartphone.

Krisdonia

Whether you're going on an extended business trip or enjoying the outdoors for a few nights, you'll want the Krisdonia 60000mAh AC Power Bank in tow, especially if you're bringing your smartphone and Steam Deck with you.

If the name hasn't given it away already, the Krisdonia AC Power Bank has a massive maximum battery capacity of 60,000mAh. Considering the battery capacity of the Steam Deck is only 5,313mAh, the Krisdonia 60,000mAh AC Power Bank has enough juice to charge the Steam Deck multiple times. What's also nice is that you can keep track of how much power you're burning through by using the helpful LCD that displays the remaining charge.

With that said, the Krisdonia 60000mAh AC Power Bank is a bit overkill if you're using it solely for the Steam Deck. It's best used in the hands of someone who often travels and needs several devices charged at once, given that it has four options for powering devices.

Anker

The Anker PowerCore III Elite is a respectable power bank that puts speed and efficiency above all else. It has a maximum capacity of 25,600mAh, which is more than enough to fully charge the Steam Deck multiple times.

But it's how the Anker PowerCore III Elite delivers the power that makes it quick and efficient. It automatically adjusts its maximum power distribution to perfectly match the device it's connected to—in this case, 45W to match the Steam Deck's original charger. And if you need to charge a different device in a pinch, you get up to 60W fast charging, along with a Trickle-Charge mode for lower-power devices like smartwatches or earphones.

The Anker PowerCore III Elite makes the best of its plastic casing. Rather than opt for a smooth, featureless exterior, the power bank has a nice textured surface, making it much easier to grip and prevent accidental drops. It also comes with a convenient travel bag for easy transportation.

Best Power Bank for Multiple Devices: Crave PowerPack

Crave

The Crave PowerPack is a high-capacity battery that, at full charge, provides 50,000mAh of power to any given device. In the case of a Steam Deck, you'll be able to fully charge the handheld gaming device multiple times before draining the power bank completely. And with that much capacity, you should have no problem charging your smartphone and other devices too.

Keeping the hardware safe inside is a hard plastic casing that's fairly durable; the Crave PowerPack has the strength to withstand a few bumps and drops without damaging the internal electronics. It's far too big and bulky to carry freehand, though, so you're better off avoiding the matter altogether by storing it in its included travel case for safekeeping.

The Crave PowerPack features a total of four USB ports for charging your Steam Deck or, alternatively, for recharging four devices all at once, which definitely comes in handy during a long trip or power outage. It also has a helpful LED indicator to display the remaining battery life.

FAQ

Q: What does pass-through mean in connection with power banks?

Pass-through technology is simple: if a power bank has that feature, it can charge devices and be charged via outlet simultaneously.

It's a very convienant feature to have, not to mention incredibly efficient. Why charge both devices separately when you can do both? However, not all power banks have pass-through technology, so if that's a feature you'd like to have on hand, double-check with the product's specifications first.

Q: What does mAh mean?

You'll quickly notice that all power banks have a number followed by 'mAh.' That stands for milliampere hours, a measurement determining a power bank's maximum capacity.

When picking a power bank, the higher its mAh, the more power it can provide the device before being depleted. Afterward, the power bank must be recharged before it can be of service again.

Q: How long does the Steam Deck's battery last?

The original Steam Deck will net you about two to eight hours of battery, while the Steam Deck OLED bumps that to anywhere between three and 12 hours. Keep in mind, it’ll vary wildly depending on the game, as more graphically intensive titles will drain the Steam Deck faster.

Q: Why does the Steam Deck OLED Edition's battery last longer?

Simply put: the Steam Deck OLED is far more efficient at 50Whr as opposed to the original model’s 40Whr battery.

Q: Can I use a power bank with my Steam Deck?

Of course! When looking for a power bank, make sure its capacity is at least 5,313mAh (the Steam Deck’s capacity) and that it delivers 45W of power.

Q: Is a 65W power bank alright for my Steam Deck? If not, what wattage do I need?

Yes, it is absolutely fine to use a 65W power bank for your Steam Deck or Steam Deck OLED. However, keep in mind your Steam Deck won’t charge any faster due to it only being able to take advantage of 45W.

Q: What type of cable do I need to charge my Steam Deck?

Whether you have the original Steam Deck or the Steam Deck OLED, you’ll need a USB-C cable to charge the devices.
