An $8.66 45W Power Bank Built for Gaming On the Go

A 45W USB-C power bank for less than nine bucks isn’t a typo. Amazon’s Spring Sale has the flashy red Iniu 10,000mAh 45W Power Bank down to $8.66 when you "clip the coupon" on the product page. You don’t need Prime, and the price undercuts anything else at this capacity from a brand most people actually recognize.

For handheld gamers, that’s a steal. Iniu’s brick is tiny at 4.3 x 2.7 x 0.7 inches and just 6.4 ounces, so it won’t weigh down a Switch case or Steam Deck sling. Capacity lands at 10,000mAh (37Wh), which is the sweet spot for slipping through TSA and still getting meaningful top-ups on the go.

It’s also the best current price for a 10,000mAh power bank from a popular, reputable brand. If you’ve been eyeing a backup for your Nintendo Switch, the rumored Switch 2, Steam Deck, or an Apple iPhone 17, this is the kind of impulse buy that makes sense.

What 10,000mAh Really Gets You

Real-world battery transfers aren’t 1:1, so assume roughly 80% efficiency. Using that yardstick, here’s how far a 37Wh pack goes with today’s handhelds and phones:

  • Nintendo Switch (16Wh): about 1.9 full charges
  • Nintendo Switch 2 (20Wh): about 1.5 full charges
  • Steam Deck (40Wh): about 0.74 of a full charge
  • Apple iPhone 17 (14Wh): about 2.1 full charges
  • Apple iPhone 17 Pro Max (20Wh): about 1.5 full charges

Those estimates line up with typical use and assume you’re not gaming during the entire charge. Cable quality, background apps, and heat can nudge results up or down, but the takeaway is clear: this little pack can push a full evening of play or carry your phone through a heavy travel day.

Ports, Speed, and Small Touches

Iniu outfits the bank with three outputs: two 45W USB-C ports plus one USB-A. The headlining 45W USB Power Delivery means it can feed devices that demand faster rates. Nintendo Switch draws up to 18W and Steam Deck up to 40W, so you’re covered at their top speeds. On the phone side, ChargerLAB’s testing shows iPhone 17 caps around 30W and iPhone 17 Pro around 37W. In other words, you’ll hit the phone’s ceiling before the charger breaks a sweat.

Small quality-of-life thing you might miss in photos: the built-in lanyard doubles as a 5-inch USB-C cable. That’s handy for quick top-ups without digging around in a bag, and it’s one less cable to forget when you’re packing a case.
