After writing up the new power bank rules, a couple of people asked what I'd actually swap to if my old brick doesn't clear the new 100Wh cap. This is the one I landed on for the "small enough that keeping it in a seat pocket isn't annoying" category — which, under the new no-overhead-bin rule, is basically the whole game now.
The INIU 10,000mAh 45W PD Power Bank is the pick we flagged in our piece on the 2026 power bank rule changes for anyone who wants a battery that clears every airline's cap with real margin to spare, not one you have to double-check the fine print on.

Why the margin under 100Wh actually matters
Run the math the way we walked through in the power bank rules piece — Wh = (mAh ÷ 1000) × 3.7 — and 10,000mAh comes out to roughly 37Wh. That's not just "under the 100Wh line," it's under it with enough room that you're never going to be the person an agent pulls aside to ask about approval. A bigger 20,000mAh-plus bank creeps close enough to that limit that it can trigger extra questions; this one just doesn't.
The other piece that matters under the new rules specifically: it has to live in your seat pocket or on your person now, not the overhead bin. At 7 ounces and genuinely slim, that's a non-issue here in a way it wouldn't be with a bulkier, higher-capacity brick.
Pro tip: the mAh number on the box is not the number airlines regulate — do the Wh math on whatever you already own before assuming it's fine, this one included. INIU's own 45W badge is about charging speed, not the battery's actual watt-hour rating.
What we like
- Comfortably under every airline's 100Wh cap, with real margin, not sitting right at the edge.
- 45W PD fast charging is genuinely quick for a battery this small and light.
- Two USB-A ports plus USB-C means it can realistically charge two devices, useful when you're solo and there's no one else's charger to borrow.
- Built-in flashlight is a small unplanned bonus for a delayed flight or a fumbling-in-the-dark hotel room moment.
What could be better
- No digital percentage readout, just an analog light-bar indicator — less precise than a numeric display if you like knowing exactly how much charge is left.
- The Wh rating isn't printed clearly on the unit itself, which is a broader industry problem, not unique to this one, but worth knowing before an agent ever asks.
- Splitting output across two devices at once slows down both, as with any power bank this size — fine for topping up, not ideal if both devices are nearly dead.
Who it's for
Solo travelers who want one no-fuss backup battery that clears the new airline rules without a second thought, especially now that it has to live in a seat pocket rather than get buried in an overhead bin. If raw brand recognition matters more to you than charging speed, see our Anker 313 review for the alternative we also considered.

Frequently asked questions
Is this compliant with the new 2026 airline power bank rules?
Yes — at roughly 37Wh it's well under the 100Wh threshold that needs no prior approval on any airline. You still need to keep it in your seat pocket or on your person rather than an overhead bin, and check your specific airline's stance on in-flight charging.
Can I bring two of these under the new two-power-bank limit?
Yes — two 10,000mAh banks like this one still comes in well under both the device-count cap and the per-device Wh limit most airlines have adopted.
Will 45W charge my laptop?
It'll fast-charge most phones and tablets, and some lower-power laptops, but most full-size laptops need 60W or more — check your laptop's charging wattage before counting on this as your only laptop backup.
How is this different from the Anker 313 you also mention?
This one charges faster (45W vs 15W) and costs slightly less; the Anker trades some speed for a more recognizable brand name and a slightly slimmer profile. See our Anker 313 review for the full comparison.
