INIU 45W Portable Charger 10000mAh Review: Is It Worth Buying
The INIU 45W 10000mAh is a compact power bank with a built-in USB-C cable plus a spare detachable one, and it genuinely fits in a jeans pocket. It charges fast — for a power bank this size — but 45W is the port's combined rating, not what actually lands in your phone. Get it if your real complaint is bulk and tangled cables in your bag, not chasing a capacity record.
You know the drill: a brick-sized power bank rattling around your bag, plus a separate cable that always manages to go missing right when your phone hits 3%. I carried a standard 10000mAh unit like that for years before I started hunting for something smaller with the same charge in reserve. That's exactly the itch the category behind the INIU 45W Fast Charging Portable Charger scratches — the maker claims "40% smaller" than a typical power bank of the same capacity, and that's really the whole pitch worth examining.
First impression: yes, it's genuinely compact. You pick it up and think "wait, this is 10000mAh?" — it's noticeably thinner than the usual brick. That's not a gimmick for its own sake; thickness and pocket weight are things you feel every single day, not just something you notice once while skimming a spec sheet. It has a built-in cable, which has become INIU's signature move over the last few years, and there's also a detachable cable in the box — so when the built-in one eventually wears out (and with built-in cables, it will, that's just physics), you've got a backup instead of a dead brick.
Now, about that 45W figure, because it's the number that trips people up most. It isn't "45W into your iPhone" — it's the combined rating of the port handling input plus output, and in practice your phone only pulls as much as its own fast-charging protocol allows, usually 20-27W on current flagships. So charging will be noticeably faster than a cheap old 10W power bank, but it's nowhere near desktop-charging-station territory. Honestly, for the real-world scenario of "top up my phone twice during a commute," that's more than enough, and this is exactly where INIU earns its niche — not a record-setter, but no slouch either.
Stacked against the category's classic rival, Anker, INIU typically wins on compactness and price, while Anker more often wins on brand recognition and service network. Judging purely on the size-to-capacity trade-off, INIU runs the "smaller and lighter for a bit less flexibility" formula — the built-in cable is convenient until you need to charge something with a different port, and that's when the spare detachable cable earns its keep. For anyone who carries a power bank as a permanent backup rather than pulling it out once a week, that thinness difference is noticeable within the first month — the backpack zips easier, the pocket doesn't bulge.
There are downsides worth saying plainly, too. First, 10000mAh gets you one or two full charges on a modern flagship phone, no more — if you're heading off-grid for a multi-day camping trip, that's not enough, look at 20000mAh models instead. Second, compact bodies with a built-in cable tend to handle physical port wear worse over time; that's not an INIU-specific flaw, it's a trait of the whole form factor. And third, the design is strictly utilitarian — if you want something that matches your decor or feels premium in the hand, this leans practical over pretty.

Who should buy it. If you're someone who carries a phone and a power bank in the same pocket or small bag every day and you're sick of hauling a brick with a separate cable that always vanishes — this is the one. If you need a reserve charge to get through the day, not weekend-long off-grid autonomy — it fits too. But if you're planning serious travel, several days away from an outlet, or you need to charge a laptop — look at higher-capacity models with real 65W+ output; this isn't the tool for that job.
FAQ
For one modern flagship with a big screen, that's roughly one full charge cycle plus a bit more. For an ordinary day of topping up before your phone dies by evening, it's plenty. For two people or two devices back to back, it's cutting it close.
No — that's the port's combined rating, not a guaranteed speed into your specific device. Real-world speed depends on your phone's own fast-charging protocol, usually 20-27W even on flagships. Faster than a cheap basic power bank? Definitely.
If compactness and price top your list, INIU wins. If brand reputation, service support, and a bit more power matter more to you, look at Anker instead — even though it's a touch thicker in your pocket.
Yes, and it's not really an extra cost — it's insurance. A built-in port physically wears out faster over time than a standard USB-C jack. With a spare detachable cable on hand, one broken wire won't leave you with a dead power bank.
