Exclusive: 55% Off Top Switch 2 Power Bank

While Prime Day deals have ended, one hidden tech gem for Nintendo Switch 2 owners remains—the INIU 45W 20000mAh Power Bank. Normally priced at $39.99, applying code Y7R7A2A7 at checkout brings the cost down to just $20.34.

That's a savings of over 55% on a charger delivering top-tier 45W PD 3.1 charging, support for three devices at once, and a smart LED display that clearly shows remaining battery and estimated recharge time.

This sleek model comes with a built-in USB-C cable, triple charging capability, and can power an iPhone 16 to 70% in only 25 minutes.

Weighing 13.1 ounces, it's significantly lighter than INIU's 27,000mAh power bank (22 ounces), making it ideal for travelers with limited bag space, those preferring a minimalist setup, or anyone aiming to save as much as possible.

Given the Switch 2's internal battery is roughly 5220mAh, you can quickly jump back into Mario Kart World or dive into Donkey Kong Bananza launching this week.

For something more compact but still Switch 2–compatible, INIU’s 45W 10,000mAh power bank is also on sale at Amazon today—just $11.65 after applying the 47% off coupon on the product page.
