Payload is the specification, and balancing is the skill it demands · review

hohem iSteady Pro 4, 150 g payload, three axes, 3600 mAh review

The only stabiliser here to publish what it can actually carry — 150 g, 51 mm, 30 mm — and the only one with a splash rating and a battery that will charge the camera on it.

By Jean-Benoit Buisson

The bottom line The most useful specification on this shelf: a payload in three dimensions, a splash rating, and a battery that outlasts the camera and then charges it. The omission is its own mass, which is the figure you carry.

On the listing

A three-axis gimbal for action cameras weighing up to 150 g, up to 51 mm tall and up to 30 mm deep, named as compatible with GoPro Hero 5 through 13, Osmo Action and Insta360 One R; the iSteady 5.0 anti-shake algorithm with IPX4 splash resistance, offered for daily vlogging through to extreme sport; a quick-release clip and working modes switched by a mode button; remote control and one-click shooting, with 600 degree 3D rotation among the modes; and a 3600 mAh battery rated at 14 hours, able to act as a power bank for a camera with a short runtime.

A payload in three dimensions

One hundred and fifty grams, fifty-one millimetres, thirty millimetres.

Neither of the two dearer stabilisers on this shelf publishes a payload at all. This one publishes the whole envelope, and the two dimensions matter as much as the mass: the jaws have to close round the camera, and a body thicker than 30 mm will not go in whatever it weighs.

For a buyer matching this to a camera already owned, that is the difference between a decision and a gamble.

Fourteen hours, and what the surplus is for

The fifth bullet does two things. It rates the 3600 mAh cell at fourteen hours of use, and it names the power-bank function as being for a camera with a short battery of its own.

That is a real pairing. Action cameras on this site quote around ninety minutes a battery when they quote anything, and several publish nothing at all. A gimbal that runs all day and then refills the camera addresses the actual constraint.

Splash resistance, stated

IPX4, in the second bullet. Neither rival here claims any ingress rating, and on a device used for surf and snow that is worth its line.

The figure it leaves out

Its own weight. The page publishes what the gimbal will carry and never what the gimbal is, which for a thing held at arm’s length for an afternoon is the number a buyer would want.

Availability

About 101 € on the German, French, Italian and Spanish Amazon stores when this page was last checked.

The American and British Amazon stores carry it too, priced in local currency. Those amounts are deliberately absent from the range above, which reads euro stores only.

Everything in this section is the figure Keepa carried on the day of the last update to this page. Availability and prices shift without notice.

What it does well, and what it gives up

Strengths

Publishes a payload in three dimensions — 150 g, 51 mm, 30 mm — where neither rival publishes one at all
Fourteen hours from 3600 mAh, and it will charge the camera it is holding
IPX4 splash resistance, stated in the second bullet, which no other stabiliser here claims

Compromises

Its own weight is never published, which matters for a device carried all day
The working modes are described as switchable without being listed, so what they do cannot be read
No control port or cable interface named anywhere

Specifications

Declared payload	Up to 150 g, with a height limit of 51 mm and a depth limit of 30 mm — all three stated in the first bullet. It is the only listing of the three here to publish a payload at all, and the dimensions matter as much as the mass: a camera within the weight but over the depth will not clamp
Axes	Three, stated in the title, with the iSteady 5.0 anti-shake algorithm named in the second bullet as the correction behind them
Battery life	14 hours from a 3600 mAh cell, stated in the fifth bullet, which adds that the gimbal doubles as a power bank for a camera with a short runtime of its own. That pairing is the point: action cameras on this site rarely publish more than ninety minutes
Balance range	Not published as a range — the first bullet gives the payload envelope in three dimensions and no adjustment travel for balancing within it
Follow modes	Several working modes switched by tapping a mode button, named in the third and fourth bullets, with 600 degree 3D rotation mentioned among them. The modes are not listed individually
Control ports	Not published on the listing — a quick-release clip and remote control are described, and no port, socket or cable interface is named
Folded weight	Not published on the listing — the gimbal’s own mass never appears, only the mass it will carry
Amazon reference	B09J7M4YH7 (same reference on 6 Amazon marketplaces)
EAN	0727542071359

What people ask before they commit

Why do the millimetres matter as much as the 150 g?

Because a clamp has to close around the camera as well as lift it. The first bullet gives 51 mm of height and 30 mm of depth alongside the mass, and a camera inside the weight limit but thicker than 30 mm simply will not fit the jaws. Most listings publish nothing at all here, which leaves a buyer guessing; this one gives the whole envelope.

How useful is the power bank function?

On this site, very. Action cameras publish runtimes around ninety minutes a battery when they publish them at all, and several publish nothing. A 3600 mAh cell rated at fourteen hours of gimbal operation has a great deal left over for the camera clamped to it, and the fifth bullet names that pairing as the design intent rather than as a side effect.
