A 20,000mAh power bank for $12 sounds too good to be true, but the deal is real. Amazon is currently selling the Kesguar 20,000mAh 22.5W Power Bank for $12.34 after applying coupon code YQQ65ZAG at checkout. For Nintendo Switch players who spend any time gaming away from an outlet, that price is hard to ignore.
What you actually get for $12
The Kesguar measures 4.5 inches long, 2.6 inches wide, and just 1 inch thick. That is compact for a 20,000mAh unit, and the aluminum shell keeps it feeling solid rather than cheap. Three outputs cover most situations: an attached 22.5W USB-C cable, a second 22.5W USB-C port, and a standard USB-A port.
The 22.5W output matters specifically for Switch 2 owners. The Nintendo Switch 2 has a 19Whr battery, and the Kesguar delivers enough wattage to charge the console while you are actively playing, meaning the battery does not drain during a session.
The Kesguar power bank comes in under the 100Wh TSA limit, so it is cleared for carry-on luggage on flights.
How many full charges does 20,000mAh actually get you
With 80% power efficiency factored in, the numbers break down like this:
For Nintendo Switch 2 owners specifically, three full recharges translates to a significant stretch of portable playtime on a single carry. The original Switch gets even more mileage out of it given its smaller 16Whr battery.
Why this price stands out
Budget power banks in the 10,000mAh range typically run $15 to $20 without any discounts. Getting double the capacity at $12.34 puts this deal in a different category. According to IGN's deals team, this is the lowest price seen for a 20,000mAh unit so far this year.
The coupon code YQQ65ZAG needs to be applied at Amazon checkout to bring the price down from the listed $29.99. That is a 59% discount on the standard price, which explains why stock at this price point may not last long.
