Although the Prime Day deals are gone, one of the best hidden tech deals for Nintendo Switch 2 owners to stick around has come from INIU. The 45W INIU 20000mAh Power Bank, typically $39.99, but you can use the code Y7R7A2A7 at checkout, and have the price drop to a mere $20.34.
That’s a great discount of over 55% off for a charger that offers top speeds with 45W PD 3.1 charging, triple-device support, and a smart LED display which tells you exactly how much juice is left and how long you’ll wait to recharge.
This compact model includes a built-in USB-C cable, triple charging, and can charge an iPhone 16 to 70% in just 25 minutes.
With a weight of 13.1 ounces, it's a good amount lighter than INIU's 27,000mAh power bank (weighing 22 ounces), so we'd recommend this one if you're travel bag space is a bit more limited, you want to travel more minimally, or you just want to save as much money as possible.
With the Switch 2's internal battery being around the same at 5220mAh, you'll be able to quickly resume Mario Kart World sessions or dive back into Donkey Kong Bananza as it launches this week.
If you're looking for something smaller but still Switch 2–friendly, INIU’s 45 10,000 mAh is also on sale at Amazon today, for just $11.65 after you clip the 47% off coupon on the product page.
This Iniu power bank holds a 10,000mAh, or 37Whr battery capacity. If you factor in 80% power efficiency, here are the approximate number of times you can fully recharge each gaming handheld:
- Nintendo Switch (16Whr) about 1.9 times
- Steam Deck (40Whr) about 0.74 times
- Apple iPhone 16 (14Whr) about 2.1 times
- Apple iPhone 16 Plus (18Whr) about 1.6 times
- Nintendo Switch 2 (20Whr) about 1.5 times
