100W Power Banks See Huge Discounts in Amazon's Early Memorial Day Sale

As the release of the Nintendo Switch 2 draws near, it’s the perfect moment to ensure your devices stay juiced, especially if you plan to game on the move this summer. Fortunately, Amazon’s early Memorial Day sales have brought two powerhouse USB-C chargers—Baseus and INIU—to their lowest prices in months.

Prime Members Only

Baseus Power Bank: 20800mAh, 145W Portable Charger

Save 50%—Only $44.79 at Amazon

Right now, both the Baseus 145W Power Bank and the INIU 25000mAh, 100W Power Bank are on sale. They’re among the best-value portable chargers under $50.

Both chargers support over 100W USB-C PD fast charging, making them ideal for powering up devices like the Steam Deck, MacBook, or the upcoming Switch 2. The Baseus model boasts up to 145W total output, allowing simultaneous charging of multiple devices such as laptops and consoles. However, it’s exclusively available to Prime Members, so I’ll also suggest a solid alternative.

I personally own the INIU power bank and highly recommend it for portable gaming enthusiasts. It’s compact enough to fit in a carry-on bag yet powerful enough to handle multi-device charging efficiently.

Nintendo claims the Switch 2 will run demanding games for a minimum of two hours on a single charge. While that’s sufficient for short commutes, longer trips or days away from power outlets call for an external power bank.

These chargers aren’t specifically designed for the Switch 2 but are fully compatible and often a better investment than niche options released post-launch. Third-party brands are already previewing magnetic chargers and clip-on cases tailored for the Switch 2’s new dimensions.
