Power Bank Clamp Holder Camera Cage with Cold Shoe Mount - Compact

In this review the Power Bank Clamp Holder from ARNARKOK proves to be a simple, purpose-built accessory for people who need to keep a phone, camera accessory or power bank mounted and powered during long shoots. The bottom line: it is for videographers and drivers who want a small, sturdy clamp that accepts thick-case phones and common power banks while adding a cold shoe for accessories. Its strongest advantage is the spring-loaded, rubber-padded jaw that holds devices securely without adding much weight to a rig.

Key Features

• Spring-loaded clamp: holds devices 53mm to 87mm wide so most power banks and large phones fit snugly without slipping.
• 1/4 in-20 threaded mount: includes a 1/4 in screw for quick installation on camera cages and tripod mounts for reliable attachment.
• Cold shoe on top: adds the ability to mount a microphone, LED or other hot shoe accessories for a more complete setup.
• Rubber-lined jaws: protect the finish of phones and power banks while improving grip and preventing scratches.
• Aluminum alloy construction: keeps the holder sturdy and durable while remaining lightweight at roughly 115g.
• Multiple mounting holes: offers flexible positioning on cages and rigs so you can place the power source where it works best.

Who It's For

This clamp is best for content creators who use mirrorless or DSLR camera rigs, truck drivers who need a radar detector or power bank mounted, and anyone who charges devices from an on-camera power source during extended shoots. The design is particularly handy for people using phones with thick cases or larger external batteries since the jaw opens wide enough to accommodate them.

Those who want a decorative piece or a multi-axis articulating arm should look elsewhere; this is a functional clamp rather than a precision positioning system. If you need waterproofing, integrated cabling, or an ultra-low-profile plate, consider a different accessory tailored to those needs.

Pros & Cons

Pros

• Compact and lightweight aluminum build that adds minimal weight to rigs.
• Secure grip from spring-loaded jaws and rubber pads that protect device surfaces.
• Versatile mounting with 1/4 in screw and multiple threaded holes for placement options.
• Cold shoe on top expands the rig by accommodating lights or mics.

Cons

• Not a full articulating mount, so fine positional adjustments require additional arms or adapters.
• Designed solely for compatible 1/4 in mounts; it needs adapters for other mounting standards.
