Meet SmallRig Nano72 20000mAh Power Bank – A 100W Portable Power Solution Built for Creators
Portable power banks have become essential accessories for anyone who regularly works with smartphones, laptops, cameras, and other electronic devices, but finding one that combines substantial battery capacity, high-speed charging, and practical mounting options is not always straightforward. Most conventional models are designed primarily for everyday charging, leaving photographers and video creators to manage additional cables, mounting accessories, and separate power solutions when working with more demanding equipment. The SmallRig Nano72 20000mAh Power Bank (Model 6108) takes a different approach by combining a 73Wh battery, up to 100W USB-C charging, a built-in retractable cable, a detachable V-Mount plate, and a smart color display in a compact, production-oriented design. Rather than functioning exclusively as a traditional portable charger, the Nano72 is intended to become part of a more flexible power setup, whether I am working at a desk, traveling, or preparing camera equipment for a recording session. Having received the Nano72 at China Gadgets Reviews, I wanted to take a closer look at its packaging, physical construction, technical capabilities, and the practical advantages offered by its combination of conventional charging features and camera-friendly mounting options.

The SmallRig Nano72 arrived in a clean white retail box that follows the company’s familiar minimalist packaging approach. The front prominently displays the SmallRig branding alongside a detailed product illustration, immediately revealing the distinctive rectangular design, integrated USB-C cable, and small digital display. Three highlighted features on the front emphasize the smart screen, removable V-shaped mounting plate, and automatic identification of low-current devices. These details communicate the Nano72’s intended versatility before the packaging is even opened. The rear of the box provides considerably more technical information, including battery capacity, charging configurations, input and output ratings, product identification, and relevant certification markings. I appreciate this approach because portable charging products are often promoted using their maximum advertised wattage without adequately explaining how performance changes when several devices are connected simultaneously. Opening the packaging reveals a straightforward presentation, with the power bank accompanied by a user manual and a small wrench for the mounting hardware. The accessories reflect the product’s positioning as a practical charging and mounting solution rather than a conventional power bank with an unnecessarily elaborate retail presentation. My initial impression of the Nano72 is that SmallRig has concentrated its attention on the device itself, particularly the mechanical design and the integration of features that would otherwise require separate accessories.

One of the first things that distinguishes the SmallRig Nano72 from ordinary power banks is its relatively thick, rectangular form factor. Instead of following the thin, flat construction commonly associated with smartphone-oriented portable chargers, SmallRig has adopted a more substantial design that resembles a miniature professional camera battery. Measuring approximately 132.5 × 53.7 × 51.5mm, the Nano72 occupies a relatively small footprint, although its thickness and approximately 512g weight give it a substantial physical presence. It is certainly portable enough to carry in a backpack, camera bag, or larger accessory compartment, but I would not describe it as an ultralight pocket charger. The exterior combines a smooth, glossy front panel with darker structural sections, textured side surfaces, and protective materials intended to improve handling. The contrast between the polished display surface and the more utilitarian body gives the Nano72 a contemporary appearance without sacrificing the industrial character expected from SmallRig equipment. I particularly appreciate the textured areas, which contribute to a more secure grip and help make the device feel appropriate for environments where equipment is frequently moved, mounted, or repositioned. SmallRig also incorporates protective silicone covers over the charging ports, helping reduce their exposure to dust and environmental contaminants when they are not being used. According to the manufacturer, the cable mechanism has been tested for more than 5,000 flex cycles, while the protective exterior incorporates drop-resistant TPU elements. These are useful design considerations, although they should not be interpreted as a formal waterproof or ruggedness certification. Overall, the Nano72 presents itself as a power accessory designed around functional requirements, with a construction that visually fits alongside camera cages, tripods, stabilizers, and other production equipment.

The mounting system is arguably the Nano72’s most distinctive feature and the main reason I find this product more interesting than a conventional 20,000mAh power bank. SmallRig provides a detachable V-Mount plate that allows the power bank to be secured to compatible mounting systems, making it suitable for various camera and video production arrangements. This approach offers considerable flexibility because the plate can be attached when a dedicated mounting position is required and removed when the Nano72 is being used as an ordinary portable charger. On the rear, the device features a 1/4″-20 threaded mounting hole and a locating hole, allowing the mounting arrangement to be adapted to compatible accessories such as magic arms, clamps, and other support systems. This is particularly useful in situations where leaving a power bank loose beside a camera would introduce unnecessary cable movement or complicate the overall setup. With an appropriate mounting accessory, the Nano72 can become a more securely positioned part of the equipment rather than another item that needs to be accommodated separately. SmallRig illustrates several possible configurations, including tripod installations, stabilizer setups, and arrangements involving light stands or other supporting equipment. For content creators who frequently change recording positions, I can see the advantage of having a portable battery that can move with the equipment without requiring an entirely different power management solution. It is worth noting that the V-Mount system primarily provides mechanical compatibility. The Nano72 delivers power through its USB connections rather than offering the specialized power outputs found on some larger professional V-Mount batteries. Compatibility with individual cameras and accessories therefore depends on their power requirements and available USB power interfaces. Nevertheless, I consider this modular mounting arrangement one of the strongest aspects of the Nano72, particularly because it does not prevent the product from serving as an everyday power bank.

Built-In 70cm Retractable USB-C Cable – A Practical Everyday Advantage
Integrated charging cables are becoming increasingly common in portable batteries, but the SmallRig Nano72 takes the concept further by incorporating a retractable USB-C cable directly into its body. The cable measures approximately 70cm in total length, with 67cm (26.4 inches) of usable extension, providing considerably more freedom than the short built-in connectors found on some compact charging accessories. The retractable mechanism allows the cable to be extended when needed and stored inside the power bank afterward, reducing cable clutter and making the Nano72 easier to organize during transportation. I find this particularly appealing because a separate USB-C cable is often one of the easiest accessories to forget when preparing equipment for travel or a recording session. The integrated cable also makes sense from a production perspective. A camera or other USB-powered device can be connected without leaving excessive cable length hanging around a tripod or mounting bracket, while the same cable remains useful for charging a smartphone or laptop during everyday activities. Another advantage is that the integrated USB-C cable supports the Nano72’s high-power charging capability, allowing it to function as a primary connection rather than simply a low-power emergency charging accessory. As with any retractable cable system, long-term reliability will depend on how the mechanism withstands repeated use. SmallRig’s stated flex-cycle testing is reassuring, although I would still recommend extending the cable carefully and avoiding unnecessary tension, especially when the power bank is attached to moving camera equipment. From a usability standpoint, this integrated solution is one of the features I would expect to appreciate most during regular operation.

The Nano72 incorporates four lithium battery cells rated at 5,000mAh each, with SmallRig advertising a combined cell capacity of 20,000mAh. More importantly, the actual battery pack is specified at 14.6V and 73Wh, which provides a clearer indication of the energy available for charging different types of electronic equipment. The distinction between the advertised 20,000mAh cell capacity and the 5,000mAh battery pack rating at 14.6V is related to the four-cell series configuration. These figures describe the same battery system from different electrical perspectives rather than indicating a capacity discrepancy. The product packaging also specifies a rated output capacity of 11,600mAh at 5V/3A. This lower figure reflects the output conditions and energy conversion involved in delivering power to external devices, and it is an important consideration when comparing actual charging expectations with headline capacity figures. In terms of power delivery, the Nano72 supports up to 100W through either its integrated USB-C cable or its dedicated USB-C port when one USB-C connection is operating independently. Supported USB-C voltage profiles include 5V/3A, 9V/3A, 12V/3A, 15V/3A, and 20V/5A, covering a broad range of compatible devices, from smartphones and tablets to laptops and USB-powered camera accessories. The USB-A port provides an additional charging option with a maximum rated output of 22.5W. I consider the 100W capability particularly significant because it extends the Nano72’s usefulness well beyond conventional phone charging. A compatible laptop that supports USB-C Power Delivery can potentially take advantage of a substantially higher charging rate than would be possible with a basic portable battery. However, the maximum charging wattage depends on the connected device, its charging protocol, battery condition, and the power requested through the connection. A 100W-rated output does not mean every attached device will charge at 100W. The Nano72 also supports up to 100W input through USB-C, allowing the battery itself to be recharged using a sufficiently capable USB-C power adapter. Actual replenishment times will depend on the adapter, charging conditions, and the battery’s power management behavior. Without controlled charging measurements, I would avoid quoting a definitive full-recharge time, but the available input rating is promising for users who need to replenish portable power between recording sessions or during travel.

The SmallRig Nano72 offers three simultaneous charging connections: its integrated retractable USB-C cable, a separate USB-C port, and a USB-A port. This makes it possible to connect multiple devices without carrying an additional power distribution accessory, although the available output changes substantially depending on how many connections are active. With one USB-C connection in use, the Nano72 can deliver up to 100W, while the USB-A port can provide up to 22.5W when used independently. When both USB-C connections are operating simultaneously, the specified distribution becomes 10W + 10W. The same 10W + 10W allocation applies when combining one USB-C connection with the USB-A port. When all three outputs are active, the available power is divided into 7W + 7W + 6W, maintaining a maximum combined output of 20W. This is an important detail because the advertised 100W capability applies to single-port USB-C operation, not to the combined output of all three connections. For my own assessment, I would therefore regard the Nano72 primarily as a high-power single-device charger that also offers the convenience of charging several smaller devices at reduced power. The multi-device mode should work well for less demanding accessories, particularly when charging speed is not the main priority. However, users expecting to power a laptop at high wattage while simultaneously fast-charging other devices will need to account for this limitation. I appreciate that SmallRig publishes the individual power allocations, as this makes it easier to plan a charging arrangement around the actual requirements of connected equipment.

Smart TFT Display – More Than a Battery Percentage Indicator
Another feature that deserves attention is the integrated color TFT display, positioned behind the glossy front panel. Many portable chargers provide only a simple percentage indicator or a small group of LEDs, leaving users with limited information about how the battery is performing. The Nano72 offers a more informative interface divided into two display pages, making it possible to monitor both immediate charging activity and the general condition of the internal battery. The first screen displays the remaining battery percentage alongside the active input and output power values. Separate indicators identify the retractable USB-C cable as C1, the dedicated USB-C port as C2, and the USB-A connection as A. Directional arrows distinguish charging input from power output, while active connections are highlighted and inactive ones appear in a subdued color. This arrangement is particularly useful because it allows the user to understand which connections are operating and how much power is being transferred without having to rely entirely on the connected device’s own charging indicator. A single press of the power button switches to the second screen, where the Nano72 displays additional battery information, including internal temperature, charge cycle count, battery health percentage, and battery pack voltage. I find the inclusion of battery health monitoring particularly welcome. Portable power banks are often treated as disposable accessories, even though the condition of their internal cells gradually changes over time. The ability to monitor battery health and cycle count provides greater transparency about the product’s condition and could prove useful for anyone who depends on portable power during repeated working sessions. SmallRig also includes a notification mechanism designed to advise replacement when the battery health falls below 80%. The display does not transform the Nano72 into a laboratory-grade battery analyzer, but it provides more meaningful information than the basic indicators found on many competing products.

With a battery capacity of 73Wh and output support reaching 100W, electrical protection and thermal management are important considerations. SmallRig equips the Nano72 with a battery management system designed to provide protection against short circuits, overcurrent, overvoltage, undervoltage, and excessive temperatures. These safeguards are intended to help manage charging and discharging conditions while reducing the risks associated with abnormal electrical behavior. The manufacturer also emphasizes the internal arrangement of the battery cells and electronic protection circuitry, presenting the Nano72 as a portable power solution suitable for both everyday equipment and more demanding creative applications. Although these features are reassuring, their real-world effectiveness cannot be established from specifications alone without dedicated electrical and thermal testing. The battery’s 73Wh rating is also relevant for air travel, as it falls below the commonly applied 100Wh threshold for lithium-ion power banks carried in cabin baggage. Airline-specific policies still need to be checked, and power banks generally must not be placed in checked luggage. For anyone who regularly travels with camera equipment, this combination of substantial capacity, clearly indicated battery specifications, and a relatively compact form factor is a practical advantage.

What I find most appealing about the SmallRig Nano72 is not any individual specification, but the way several useful features have been brought together into one coherent design. The retractable USB-C cable addresses cable management, the dedicated USB-C and USB-A connections provide additional compatibility, the color screen improves visibility into the battery’s operation, and the mounting system introduces flexibility that ordinary portable power banks rarely offer. The Nano72 also occupies an interesting position between consumer charging equipment and professional camera accessories. On one hand, it can serve as a portable 100W USB-C charging solution for compatible laptops, smartphones, tablets, and other electronics. On the other, the detachable V-Mount plate and threaded mounting interface make it suitable for more carefully organized shooting setups where securing the power source is just as important as supplying energy. I also like that SmallRig has retained a relatively simple user interface despite incorporating additional monitoring information. The two-screen layout keeps the most relevant details accessible without introducing a complicated menu system.

The approximately 512g weight makes the Nano72 more substantial than its palm-sized appearance might suggest, especially for users who prioritize lightweight travel accessories. Its thicker construction also means that it is more naturally suited to a camera bag or backpack than a trouser pocket. The 20W combined limit during multi-device charging is another important consideration. While three connections are convenient, their simultaneous power allocation is considerably more restrictive than the 100W headline rating might initially imply. These limitations do not necessarily diminish the product’s appeal, but they reinforce the importance of understanding its intended use. For creators who value secure mounting and high-power charging through a single connection, the Nano72 offers a compelling combination. For users whose main priority is charging multiple power-hungry devices at maximum speed simultaneously, a different power distribution architecture may be more appropriate.

The SmallRig Nano72 20000mAh Power Bank stands out as a portable charging solution that has been designed with photographers, video creators, and technically demanding users in mind, while remaining useful for everyday electronics. Its most convincing qualities are the 73Wh battery capacity, up to 100W bidirectional USB-C charging, integrated 67cm usable retractable cable, detachable V-Mount plate, versatile 1/4″-20 mounting interface, and informative color display. Individually, these features are not entirely new, but their combination in a relatively compact device makes the Nano72 more versatile than a typical portable battery. I particularly appreciate SmallRig’s decision to incorporate professional mounting options without making the product dependent on a specialized camera setup. The ability to remove the V-Mount plate and continue using the Nano72 as a standard USB power bank gives it a broader range of applications and makes the additional hardware feel genuinely purposeful. The detailed battery monitoring screen is another welcome addition, especially for users who want more visibility into charging behavior and long-term battery condition. The main compromises are its relatively substantial weight and the sharp reduction in available charging power when multiple outputs are used simultaneously. These are worth considering before purchase, particularly for anyone expecting a combined 100W multi-device output. My verdict: The SmallRig Nano72 is a thoughtfully designed power bank that successfully bridges everyday USB-C charging and camera-oriented power management. It is especially appealing to content creators who want a single portable battery that can be carried between locations, attached securely to compatible equipment, and used to power a variety of devices without excessive cable clutter. Its value lies not simply in the advertised 20,000mAh capacity or 100W output, but in the practical flexibility of its overall design. For users who understand its single-port performance advantage and multi-port limitations, the Nano72 represents a well-considered addition to a modern portable production setup.
