If your phone battery is the kind of drama queen that dies at 40%, today's INIU power bank deals on Amazon are going to feel like a much-needed intervention. I'm talking real savings on chargers that actually do what they claim. No overheating, no slow trickle charging, and no clunky bricks taking up half your bag.

I've rounded up the best picks from INIU's lineup, including the thinnest 10,000mAh power bank I've seen, a laptop-grade 100W beast, and everything in between. These are well-rated, fast-charging, and surprisingly affordable today. And yes, they all come with a 3-year warranty, because INIU apparently believes in accountability (what a concept).

This is the one I'd keep in my bag daily. It's half an inch thick and can charge an iPhone 8 about 3.6 times or a Galaxy S22 almost twice. The USB-C port handles both input and output (a rarity at this price), and the dual USB-A ports mean you can charge multiple devices without carrying five bricks. It's cheap, sleek, and has a literal paw print on it. Adorable and useful? Yes, please.

I think this is the sweet spot if you bounce between devices. You get three outputs, including one that'll fast-charge a MacBook Pro 14" or your Steam Deck while you're multitasking. There's even a pop-out phone stand built in. It's like if your power bank also respected your time and your binge-watching habits. At under $40, it feels like a steal.

This is my pick for weekend trips or carry-on duty. It's got solid charging speed, a clean LED display that shows exactly how much juice is left, and enough capacity to last through a few full phone charges. It even handles smaller accessories like AirPods or smartwatches without flinching, which is more than I can say for some people.

If I'm packing a laptop, a tablet, a phone, and something else probably unnecessary but still USB-powered, this is what I'm bringing. It hits 100W output, recharges itself fast via USB-C, and can handle charging multiple high-power devices at once. It's a bit of a tank, but in the way you want when you're relying on it to keep everything alive.

If I had to pick a favorite just for everyday carry, it might be this one. It's compact, fast, and charges three devices at once. I love the built-in phone stand, especially for killing time in waiting rooms or pretending I'm not watching TikTok in public. For $20, it's a little charger that does a lot.
