You're three hours into a long flight, deep into a session on the Nintendo Switch, and the battery warning hits. For $9.99, that scenario gets a lot less stressful.
Amazon is currently selling the Aaoyun 10,000mAh 22.5W Power Bank for just $9.99, down from its listed price of $19.99. No coupon code needed, no Prime membership required. At that price, it's one of the more straightforward accessory deals for Switch owners right now.
What a 10,000mAh bank actually does for your Switch battery
Here's the thing: the Nintendo Switch has a 4,310mAh battery, and the Switch 2 bumps that up modestly to 5,220mAh (20Wh). Neither is exactly a marathon runner. Nintendo's own specs put Switch 2 handheld play time at between 2 and 6.5 hours depending on the game, which means demanding titles will drain it closer to that 2-hour floor.
A 10,000mAh bank at 80% power efficiency can recharge the original Switch approximately 1.9 times and the Switch 2 about 1.5 times. That translates to a meaningful extension of your total session, pushing what might be a 3-hour trip into something that lasts the whole journey.
The more useful spec, though, is the 22.5W Power Delivery output. That's enough to charge both the Switch and Switch 2 at their maximum rate, and critically, it means you can play while plugged in without the battery actively draining. The power input keeps pace with what the hardware draws during active play.
What you're actually getting for $10
The Aaoyun bank ships with a built-in 2.2ft USB-C cable that tucks back into the body when not in use, plugging into the device's own USB-C port as a storage point. There's also a dedicated 22.5W USB-C output port and a USB-A port for older cables.
The casing is solid metal rather than plastic, which helps with heat dissipation during extended charging sessions. A simple LED meter gives a rough read on remaining capacity. Aaoyun also claims the built-in cable is sturdy enough to function as a short lanyard, though that's more of a bonus than a selling point.
The brand isn't a household name, but the product has cleared 1,000 reviews on Amazon with a generally positive reception, which is a reasonable signal for a budget accessory.

The Aaoyun bank also works with the Steam Deck (though it'll only get you about 0.74 of a full charge given the Deck's 40Wh battery) and standard smartphones like the iPhone 17.
Why this deal lands right now
With the Switch 2 launch approaching, accessory pricing tends to creep upward as demand builds. Getting a capable, metal-cased power bank with 22.5W output for under $10 is the kind of deal that doesn't require much deliberation.
What most players miss is that wattage matters as much as capacity. A high-capacity bank with only 5W or 10W output will charge your Switch slowly and may not keep up with power draw during play. The 22.5W spec here clears that bar comfortably.
