Key Steam Deck Battery Bank Considerations
These are the top four things to consider before buying power banks for your Steam Deck:
Output Power
The output power or power draw of a power bank is an important consideration when buying one for your Steam Deck. Steam Deck usually takes up to 45 watts of power when plugged into a power bank.
If your source doesn’t provide that much output, your Deck continue to loose battery life even while it is plugged in. This is especially true if you playing games while you charge.
Airplane Limits
If you’re an avid traveler, you must consider the legal limit of the power bank you intend to buy. Most airlines have a maximum legal limit of 100-watt-hour or 27,000 milliamps for portable power bank.
If your portable charger is above this limit, you cannot take it on an airplane.
Advertised vs Actual Capacity
One other important thing to consider when buying a power bank for your Deck is the advertised capacity in milliamps hours. The advertised capacity is different from the true power that the power bank outputs to the Steam Deck due to resistance and energy lost in the form of heat.
The true output power depends on your operating voltage.
For instance, if you buy a power bank rated 20,000mAh and your operating voltage is 14.8V, the power bank will only output 5000mAh. Similarly, a 20,000mAh power bank will output 12,000mAh at 5V.
The higher the operating voltage, the lower the output power.
Size and Shape
If you plan on charging up your Deck while you continue to play, then the size and the shape of your power bank becomes a big factor. If you are playing, you’ll want something with a long cord so that it can sit off to the side or else something thin and easy to hold in place while you hold the Deck.
If this sounds like a big deal to you, make sure to check out the Anktank power bank below, which is made with a magnetic attachment for the back of your Deck.
Let’s go into all of our top power banks in more detail now.
