Publishes its size, and names a different model in its own bullet
INIU P61-E1, 10000 mAh 45 W with stand
The INIU that publishes its dimensions and its weight, translates its capacity into four kinds of device — and names a different model number in its own second bullet.
This is the INIU that answers the question “how big is it” — 4.4 by 2.7 by 0.7 inches and 6.5 ounces — where its cheaper sibling on this shelf claims to be 40 per cent smaller and publishes nothing at all. It also translates the capacity into something usable four ways over: up to two iPhone charges, 1.2 for an iPad Air, twenty for an Apple Watch, twelve for a set of AirPods Pro. That is the most granular capacity statement on this shelf, and it is the right way to express 10,000 mAh to somebody who is deciding whether to pack it.
The two additions are small and genuinely useful. A built-in stand means that a bank with a phone plugged into it stops being a block under the screen and becomes a prop holding the screen up — the one thing you want on a tray table — and no other bank in this hub has one. The flashlight is the same thought in miniature, for a dark cabin with your bag under the seat.
Two things on the page need reading carefully. The second bullet calls the product P55 while the reference is P61-E1, which is bullet text carried over between generations of the same body — so the 27 per cent and the dimensions in that sentence belong to whichever unit it was written for, and the reference below is what identifies what ships. And unlike the cheaper INIU on this shelf, the charging percentages here come with no starting charge: an iPhone 17 Pro to 65 per cent and a Galaxy S26 Ultra to 75 in thirty minutes, from a level the page does not state. A battery charges fastest when nearly empty, so the baseline is the figure that makes the claim mean something.
The watt-hour rating is missing, as it is on all seven banks in the American half of this hub, under the words “Airline-friendly power”. By the formula in this shelf’s buying tip, 10,000 mAh at about 3.7 V is roughly 37 Wh, well under the 100 Wh limit — our arithmetic, because the page does not do it.

What travelers ask
Which model is this?
The reference is P61-E1 and the second bullet calls it P55. Makers reuse bullet text between generations of the same body, and the figures in that bullet — 27 per cent smaller, 4.4 by 2.7 by 0.7 in, 6.5 oz — belong to whichever model the sentence was written for. The Amazon reference below is what identifies the unit that ships, and it is worth checking the dimensions against the pictures if the size is the reason you are buying.
Is the stand worth anything?
On a tray table, yes. A power bank with a phone plugged into it normally ends up lying flat with the phone on top of it, which is the one position where you cannot watch the screen; a built-in stand turns the same object into a prop at a viewing angle while it charges. No other bank in this hub has one. The flashlight is the smaller version of the same thought — the thing you need when the cabin lights are off and your bag is under the seat.
This one or the cheaper INIU?
Same capacity, same 45 W, same maker, a few dollars apart. This one publishes its dimensions and its weight, translates its capacity into four device types, and adds a stand and a light. The cheaper one states the starting charge behind every percentage claim, which this one does not, and argues its case for a detachable cable more fully. If the size is the reason you are buying, this is the page with the figures; if the charging speed is, the other page is the one with the baseline.
