The short answer is: it depends, but expect it to take considerably longer than with the official 45W charger. While your Steam Deck will charge with most USB chargers, including those for your phone, the charging time can vary significantly based on the charger’s wattage. A standard phone charger, often ranging from 5W to 20W, will charge your Steam Deck, but it will be a slow process. Expect a full charge to take anywhere from 4 to 8 hours, or even longer, depending on the charger and whether you’re using the device while it’s charging.
Understanding Steam Deck’s Power Requirements
The Steam Deck is designed to use a 45W USB-C Power Delivery (PD) charger for optimal charging speeds. The device houses a 5,313mAh battery. When using the recommended charger, it typically takes between 2 to 3 hours to fully charge. This is because the Steam Deck can draw a maximum power close to 40W when charging. A phone charger, with its lower wattage, simply can’t deliver power as quickly, resulting in extended charging times.
Why Phone Chargers Are Slower
Phone chargers are designed to charge devices with much smaller batteries and lower power requirements than the Steam Deck. While technically compatible thanks to the USB-C standard, the power output difference is significant. An iPhone 4 charger at 5V/1A (5W) will charge the Steam Deck, but incredibly slowly, as demonstrated in the original context, taking 1.5 hours to charge from 85% to 100%. A more modern phone charger at 18W or 20W will be faster, but still far from the optimal 45W, so prepare for a slower charging experience.
Factors Affecting Charging Time
Several factors can influence how long it takes to charge your Steam Deck with a phone charger:
-
Charger Wattage: The most significant factor. A higher wattage charger will always charge faster, up to the device’s maximum draw.
-
Cable Quality: A high-quality USB-C cable is essential. A poor-quality cable can restrict the amount of power that can flow through it, further slowing down charging. Some cables are not rated for higher wattage charging, so make sure your cable is rated for at least the wattage of your charger.
-
Device Usage: Using the Steam Deck while charging will drastically increase the charging time. The device is using power while simultaneously trying to charge, negating much of the charging benefit. Avoid playing games or running demanding applications while charging with a low-wattage charger.
-
Ambient Temperature: Extreme temperatures can affect charging efficiency. Charging is generally most efficient at room temperature.
-
Battery Health: An older battery may not charge as efficiently as a new one, potentially increasing charging time.
Alternatives to the Official Charger
While the 45W charger is recommended, there are alternatives if you need a faster charge than what a phone charger can offer:
-
High-Wattage USB-C Chargers: Any USB-C charger with a wattage of 45W or higher will work well with the Steam Deck. You can use a 65W, 100W, or even 120W charger without issue. The Steam Deck will only draw the power it needs.
-
Power Banks: A power bank with USB-C PD support is a great option for charging on the go. Look for power banks with a capacity of 20000mAh or higher and a 45W PD output for best results.
Precautions for using non-official chargers
Ensure that any non-official charger you use is from a reputable brand and that it is USB-C PD compliant to avoid damaging the Steam Deck.
Frequently Asked Questions (FAQs)
1. Can I use any USB charger with my Steam Deck?
Yes, the Steam Deck can technically charge with any USB charger, but the charging speed will vary dramatically. A low-wattage charger, like a 5W phone charger, will charge the device, but incredibly slowly. For optimal charging, use a 45W USB-C PD charger or higher.
2. Will a 20W charger charge a Steam Deck?
Yes, a 20W charger will charge your Steam Deck, but it will take significantly longer than the recommended 45W charger. Expect charging times to be more than double compared to using the official charger.
3. Can I use a Nintendo Switch charger to charge my Steam Deck?
The Nintendo Switch charger is often rated at 39W, which is close to the 45W recommended for the Steam Deck. It will work and provide a decent charging speed, though not quite as fast as a true 45W charger.
4. Is it safe to use a higher wattage charger (e.g., 65W, 100W, 120W) with my Steam Deck?
Yes, it is perfectly safe to use a higher wattage USB-C PD charger with your Steam Deck. The device will only draw the power it needs (up to 40W), so a higher wattage charger won’t force more power into the device than it can handle.
5. How long does it take to fully charge a Steam Deck with the official charger?
Using the official 45W USB-C PD charger, it typically takes between 2 to 3 hours to fully charge the Steam Deck from empty.
6. Can I leave my Steam Deck plugged in overnight?
While technically safe, constantly leaving your Steam Deck plugged in overnight is not recommended. It can lead to “trickle charging,” where the battery repeatedly cycles between 99% and 100%, potentially reducing its lifespan over time. The general consensus among Steam Deck users is to avoid making it a regular habit.
7. Will using my Steam Deck while charging damage the battery?
Using the Steam Deck while charging, especially with demanding games, will generate heat, which can impact battery health over time. It’s best to avoid heavy usage while charging, particularly if using a lower-wattage charger.
8. What is USB Power Delivery (PD)?
USB Power Delivery (PD) is a fast-charging standard that allows devices to draw more power over a USB connection. It enables higher voltage and current levels, allowing for faster charging of larger devices like laptops and the Steam Deck.
9. What does the “Slow Charger” warning mean on my Steam Deck?
The “Slow Charger” warning indicates that the connected charger doesn’t provide enough power to charge the device optimally. This usually happens when using a charger with less than 45W. The device will still charge, but at a significantly slower rate.
10. How many times can a 20000mAh power bank charge a Steam Deck?
A 20000mAh power bank can typically charge a Steam Deck about 1.8 times, assuming minimal power loss during the charging process.
11. What’s the best power bank for the Steam Deck?
The best power bank for the Steam Deck should have a capacity of 20000mAh or higher and support 45W USB-C PD output. The Anker Prime Power Bank is an excellent option.
12. Can I use a 30W charger with my Steam Deck?
Yes, you can use a 30W charger, but the charging process will be slower compared to using a 45W charger. It’s a better option than using a 5W or 10W charger, but still not ideal for quick charging.
13. What is the lifespan of the Steam Deck battery?
The lifespan of the Steam Deck battery depends on usage and charging habits. Avoiding extreme temperatures, minimizing heavy usage while charging, and avoiding frequent overnight charging can help prolong battery life.
14. Are Thunderbolt docks officially supported with the Steam Deck?
Thunderbolt and DisplayLink docks may work with the Steam Deck, but they are not officially supported by Valve. Most USB-C compliant hubs and docks will work without issue.
15. Where can I learn more about the impact of gaming on learning?
You can learn more about the intersection of gaming and learning at the Games Learning Society, a community dedicated to exploring how games can be used for educational purposes. Visit their website at https://www.gameslearningsociety.org/ for more information.
Using a phone charger with your Steam Deck is possible in a pinch, but understanding the limitations and potential drawbacks is crucial. For the best charging experience, invest in a 45W USB-C PD charger or a compatible power bank. This will ensure your Steam Deck is always ready for your next gaming session.
