INIU Carry P50-E1 Power Bank Review

We’ve been carrying and testing the INIU Carry P50-E1 Power Bank for the past three weeks, exploring what sets it apart in the crowded 10,000 mAh space. Right out of the gate, this power bank grabbed our attention with its size—it’s noticeably smaller and more packable than you’d expect for its capacity, hovering around the size of two AirPods cases stacked together. For anyone prioritizing everyday carry minimalism, that’s an immediate point of interest. But a power bank needs more than just compact dimensions to earn a place in our kits; performance and real-world usability matter too.

We used the INIU P50-E1 alongside our smartphone, wireless earbuds, and a laptop on a recent trip, evaluating how it handled both routine and heavier demands. Between its built-in screen, integrated cable, and advertised 45 W output, there’s a lot packed into that small footprint. But the real question is how those features translate into daily convenience—especially when compared to similar 10 K options that lean into MagSafe integration or premium build quality. Let’s break down how it actually performed in the field.

The Rundown

When it comes to core performance, the INIU Carry P50-E1 Power Bank does a solid job with the devices most of us carry every day. Out of the box, the first thing you’ll notice is the tiny display on the front that shows the remaining battery percentage from 100 % down to zero. Visually, it’s straightforward—not flashy, and over time it does pick up minor scratches—but being able to glance at an exact percentage is undeniably useful when you’re on the go. That said, we didn’t find the screen essential; it’s a nice perk but not a requirement for most users.

On the output side, this power bank offers up to 45W charging via one of its USB-C ports, which, in theory, should be enough to fast-charge tablets and even smaller laptops. In practice, though, that 45W output didn’t translate into meaningful charging for a MacBook Air during our tests—instead, it merely maintained the laptop’s current battery level without adding significant charge. For everyday phones and accessories, however, it performs admirably. We charged an iPhone 17 roughly one and a half to two times on a full unit, which aligns well with expectations for a 10,000 mAh bank. Larger devices like tablets will get a partial top-up, though your mileage may vary (tablets come in so many sizes).

The inclusion of an integrated USB-C cable adds tangible value, particularly for quickly charging accessories like wireless earbuds without needing to carry extra wires. If your phone also uses USB-C, you can take advantage of faster charging directly. For those still with Lightning devices, you’ll still need a separate cable — but having at least one onboard connector is a step up from the barebones approach most power banks take. Across our testing, charging was reliable, and the unit held up well to repeated daily use without overheating or dropping connections.

What the INIU can’t do—and this is worth calling out—is replace a dedicated laptop charger in a pinch. If your goal is to keep a MacBook series machine topped up during travel or extended sessions away from a wall outlet, this power bank will keep the screen alive but won’t add a meaningful charge. That limitation doesn’t disqualify it for everyday carry, but it does set expectations appropriately: phones and smaller gadgets are well-served; full laptop charging is not.

Packability

Packability is where the INIU Carry P50-E1 Power Bank shines the brightest. In a world where high-capacity and low bulk are often at odds, this unit strikes an excellent balance—it’s noticeably slimmer and more pocketable than most 10,000 mAh power banks we’ve used. For reference, we compared it to a standard AirPods case, and the P50-E1 is only about two of those side by side in size, with just a hair more width. That means it slips into a sling, small bag, or even larger pockets without dominating space, leaving room for your wallet, keys, or a compact notebook.

We carried this power bank in a two-liter sling often used for everyday essentials, and it barely registered in terms of bulk. Unlike many chunky battery banks that force you to reorganize your bag, the INIU sat comfortably alongside other items. That’s a big plus for anyone who travels on foot or values streamlined carry. The lightweight feel also adds to that sense of ease; it’s not just compact on paper—it genuinely disappears in the context of the rest of your gear.

However, the integration of the USB-C cable does introduce a bit of management when you’re on the move. While we appreciate having that cable ready at all times, it also means there’s a tether to deal with when charging. This isn’t a showstopper by any means, but it’s something you’ll notice compared to flat MagSafe battery options that cling directly to the back of your phone without external wiring. For those who appreciate clean carry lines and minimal protrusions, this cable can feel a little like an extra limb until you get used to handling it.

Quick Comparison

Against other 10,000 mAh battery banks in a similar price and capacity bracket, the INIU Carry P50-E1 Power Bank stakes out a clear position. Compared to flatter MagSafe options from brands like the Ugreen Uno Magnetic and INIU’s own MagSafe models, the P50-E1 is more compact overall but lacks magnetic attachment to phones. That means you’ll manage a cable during charging instead of snapping the unit to your device. On the upside, it’s often lighter than those MagSafe alternatives by a slight margin. It’s not a dramatic difference, yet it’s noticeable in pocket carry.

In terms of price, at roughly $38, it undercuts or matches many competitors in the same space, making it an attractive value proposition. Most other 10K banks deliver roughly the same charge cycle performance, so differentiation comes down to features: the INIU has a built-in cable and display at a lower cost, while MagSafe options offer seamless attachment and sometimes additional kickstand features. The build quality leans a bit more plasticky and lightweight on the INIU compared to its more metal-trimmed rivals, but for carry-first users, that trade-off is often worth it.
