A 10,000mAh power bank from a reputable brand for under $9 is the kind of deal that doesn't come around often. During the Amazon Spring Sale, the Iniu 10,000mAh 45W Power Bank in red has dropped to $8.66 after clipping the coupon on the product page. No Prime membership required.
The original price sits at $21.99, making this a 61% discount. For handheld gamers who've ever watched their Nintendo Switch 2 battery crawl toward zero mid-session, this is worth paying attention to.
What you're actually getting for $8.66
Size is the first thing worth noting here. The Iniu measures just 4.3 x 2.7 x 0.7 inches and weighs 6.4 ounces, which means it fits in a jacket pocket without any drama. The 10,000mAh (37Wh) battery is the real draw, though.
Factoring in 80% power efficiency, here's how many full charges you can expect across popular devices:
For Switch 2 owners specifically, that translates to roughly doubling your handheld playtime. The Switch 2 battery lasts anywhere between 2 to 6.5 hours in handheld mode depending on the game, so the math here is pretty favorable for a sub-$10 accessory.
The 45W spec matters more than you'd think
Here's the thing: a lot of budget power banks cap out at 10W or 18W, which means your handheld charges slower than it drains during heavy gameplay. The Iniu's 45W Power Delivery spec sidesteps that problem entirely.
The Nintendo Switch charges at 18W maximum, and the Steam Deck tops out at 40W. Both fall within what this power bank delivers, meaning you're charging at full speed rather than trickling in just enough juice to slow down the battery drain. According to testing by ChargerLAB, the iPhone 17 charges at around 30W and the iPhone 17 Pro at 37W, both comfortably within the Iniu's output range.
The unit ships with three output ports: two 45W USB Type-C ports and one USB Type-A port. The built-in lanyard doubles as a 5-inch USB-C cable, which is a genuinely useful touch for travel.

Why this price point stands out
Budget power banks in the $8-10 range typically come from unrecognized brands with questionable safety records and charging speeds that top out well below what gaming handhelds actually need. Iniu has built a solid reputation in the portable charging space, which makes this particular sale price unusual rather than routine.

Who this makes sense for
Anyone who plays Switch 2 or Steam Deck on long commutes, flights, or away from a power outlet is the obvious audience. The Iniu won't fully recharge a Steam Deck from zero (it gets you to about 74%), but it will meaningfully extend a session that's running low.
For Switch and Switch 2 players, the story is better. Getting roughly 1.5 to 1.9 full recharges means you can realistically go a full day of travel without hunting for a wall outlet.
