I’ve found some great Steam Deck power banks that are discounted in the Amazon Prime Day sales

There’s nothing worse than getting halfway through a boss fight only to watch your battery warning blink on screen. That’s where these Amazon Prime Day power bank deals come in. I’ve rounded up the best ones for the Steam Deck and similar handhelds, and they all bring serious wattage, smart features, and enough capacity to keep you gaming through flights, commutes, or couch marathons. Make sure you’ve grabbed the 30-day free Amazon Prime trial to access these discounts too. Let’s get into it:

This SHARGEEK 170 isn’t just about raw power—it’s got personality. Between the futuristic clear shell, that clean smart display, and IP66 water resistance, this thing feels ready for travel. The 140W PD3.1 charging gets a full Steam Deck recharge in no time, and it can top up two other devices at once thanks to the triple-port setup. I like that it recharges itself quickly too—fully topped up in under 45 minutes via USB-C. Pricey at launch, but this 41% discount makes it way more justifiable now.

UGREEN’s 100W power bank is all about efficiency and value. You get 20,000mAh of juice, three charging ports (two USB-C and one USB-A), and fast charge support for everything from phones to laptops. The Deck charges quickly, and you can top up the power bank itself in just over 90 minutes with a 65W charger. I also appreciate the digital readout and lighter build—makes it easier to pack and keep an eye on while you’re using it.

The Anker 737 is a workhorse. At 24,000mAh, it packs enough juice to recharge your Steam Deck multiple times or even handle a MacBook mid-trip. The real highlight is the 140W fast charging with a detailed digital readout that keeps you posted on power flow and remaining juice. It’s a little chunky, but if you want something dependable with excellent safety features and broad device support, this is one of Anker’s best deals right now.

INIU’s 140W power bank brings the goods in a surprisingly compact frame. Despite holding a hefty 25,000mAh of capacity, it’s still airline approved and ready for travel. It’s got smart digital display tech, super-fast dual USB-C ports, and even hits full-speed Steam Deck charging. The build feels premium, and with support for everything from MacBooks to drones, it’s one of the most versatile chargers I’ve tested at this size.

This tiny 10,000mAh INIU pack punches way above its weight. It’s got 45W charging, a smart digital readout, and the ability to juice up a MacBook Air in a pinch. Perfect for keeping in a tech pouch or sling bag, this one’s ideal for short trips or topping up while commuting. And that built-in lanyard cable is a great little bonus for travel.

If you want full-size power in a minimal frame, the INIU 100W is the sweet spot. It’s compact for a 25,000mAh unit and still manages dual fast-charging USB-C ports and enough output to top up a laptop and Steam Deck together. For tech-heavy users or creators, this is a rock-solid daily driver.

Belkin’s 65W power bank is a sleek, minimal workhorse. With USB-C and USB-A ports, it supports up to three devices at once and has a full-color digital screen that gives you battery levels at a glance. It’s great for laptops and gaming handhelds alike, and the overall build feels like something that’ll survive daily use and then some.

This is INIU’s most compact 65W power bank to date. It’s lightweight, travel-safe, and still packs 20,000mAh of juice with fast charging. You’ll get full Steam Deck compatibility, MacBook support, and even juice for wearables. A nice middle ground if you’re after reliable all-in-one performance without carrying a battery brick.

This smaller Anker Prime unit is perfect if you want something travel-friendly but still powerful. The 65W max output is plenty for the Steam Deck, and the built-in AC plug lets you skip carrying a separate charger. It’s got a smart display, braided cable, and a sturdy metal base that makes it feel more premium than most power banks this size. Ideal for everyday carry or as a quick top-up solution that won’t weigh you down.

The CUKTECH No.20 is built like a tank. It holds 25,000mAh of charge with a high-end auto-grade battery, meaning it’ll outlast a lot of other packs—over 1,000 charge cycles according to the spec sheet. The 140W fast charging and smart TFT display make it super easy to monitor output, and I really dig the matte finish with that blue light accent. It’s slightly bigger than a soda can, so still travel-friendly despite the capacity.
