Design and Build Quality
The Betrusami 120W USB C Charger Block stands out with its compact, all-in-one design that incorporates two retractable cables. According to Newegg's product description, the device features a collapsible plug and built-in cables that extend up to 27.56 inches, offering enhanced flexibility for use at desks, beds, or airports. The silver finish and lightweight construction make it a travel-friendly option, with the company claiming the GaN IV technology reduces size and weight by up to 50% compared to traditional chargers. However, some reviewers on Reddit's r/homelab noted that while the build feels solid, the retractable mechanism could be more durable under heavy use, particularly with frequent cable pulling.
The device includes a total of four ports: one 65W USB-C port, one USB-A port, and two retractable cables (one USB-C and one Lightning). The USB-C port is positioned as the primary laptop charger, while the USB-A port supports older devices. The retractable cables are designed to automatically retract after use, preventing tangles and keeping the charging station clean. Despite these features, some users have reported that the cable retraction mechanism occasionally jams or doesn't retract smoothly, which could be a minor inconvenience for daily use.
Performance and Efficiency
The Betrusami charger utilizes GaN IV technology, which Newegg's listing claims delivers up to 92% energy conversion efficiency. This efficiency is expected to reduce heat generation and provide more stable charging compared to traditional chargers. The 65W USB-C port can charge a MacBook Pro 13-inch up to 46% in just 30 minutes, according to the manufacturer's claims, which aligns with what other reviewers have observed in real-world testing.
In terms of real-world performance, the charger is capable of delivering fast charging across multiple devices. The USB-A port supports up to 12W output, which is adequate for standard smartphones and tablets. However, some users on Reddit noted that the actual charging speeds were sometimes slower than advertised, particularly when charging multiple devices at once. The device is also compatible with Power Delivery (PD) and Power Preset Specification (PPS), which allows it to work with a wide range of devices including Samsung Galaxy tablets and Apple iPhones. The 120W total output is sufficient to power up to four devices simultaneously, though individual port speeds may be throttled depending on the load.
Compatibility and Versatility
The Betrusami 120W charger is marketed as a universal charging solution compatible with a wide array of devices. According to Newegg's listing, it supports laptops such as MacBook Air M2, MacBook Pro 14-inch, and MacBook Pro 16-inch, as well as tablets like iPad Air/Pro/Mini and smartphones including iPhone 16/15/14/13/12/11 and Samsung Galaxy S25/24/23/21. The inclusion of both USB-C and Lightning cables makes it convenient for users with mixed device types. However, some users on r/homelab have reported issues with compatibility, particularly with certain Samsung Galaxy models and newer MacBook Pro versions, where the device failed to negotiate power properly.
The device also supports a variety of Android phones, including Google Pixel and LG models, and is compatible with gaming consoles, headphones, and smartwatches. The manufacturer claims that the charger supports PPS, which is important for newer devices that require specific voltage levels. Despite this, a few reviewers noted that the device sometimes struggled to provide optimal charging for high-end smartphones, particularly those requiring fast-charging protocols beyond standard PD. The USB-C port is designed to function as a laptop charger, but users have reported that it may not be compatible with all laptop models, especially those with proprietary charging systems.
Safety and Protection Features
Safety features are a key selling point for the Betrusami charger, with the manufacturer claiming that it includes intelligent current matching, reverse charging protection, over-voltage protection, and over-temperature protection. These features are designed to ensure safe charging for all connected devices. According to Newegg's listing, the device is made from high-quality polymer material, which enhances durability and reliability. The company also notes that the GaN IV chip helps minimize heat generation during operation, which is crucial for preventing overheating and ensuring long-term performance.
However, some Reddit users have raised concerns about the safety of the device, particularly regarding its ability to maintain consistent voltage levels under load. One reviewer noted that the device occasionally shut off during high-power charging sessions, especially when multiple devices were connected. The retractable cables, while convenient, also pose a potential safety risk if they are not properly retracted or if the mechanism fails. Some users have reported that the cables became loose or disconnected during use, which could lead to charging interruptions or even damage to the device.
User Experience and Convenience
The retractable cables and collapsible plug design are major convenience features that make this charger ideal for travel and daily use. According to Newegg's listing, the retractable cables have been stretch-tested over 30,000 times and are designed to automatically retract for easy storage. This feature is particularly useful for users who frequently travel or have limited desk space. The device is also lightweight and pocketable, making it easy to carry in a bag or travel kit. Some users on Reddit have praised the compact design and ease of use, especially for those who are tired of tangled cables and messy charging setups.
Despite these advantages, some users have noted that the retractable mechanism can be finicky. A few Reddit threads reported that the cables occasionally jam or fail to retract properly, which can be frustrating during travel. Additionally, while the device is marketed as a 120W charger, some users found that the actual output was lower than expected, particularly when multiple devices were connected.
What Reviewers Loved
Several reviewers highlighted the convenience of the retractable cables and the compact design, especially for travelers and users with limited desk space. The device's ability to charge multiple devices simultaneously was also a popular feature, with some users appreciating the 120W output and the inclusion of both USB-C and Lightning cables. According to Newegg's product description, the GaN IV technology ensures faster and more stable charging with less heat than traditional chargers, which was confirmed by some users who noted improved performance compared to older chargers.
The foldable plug design was another feature that received positive feedback, as it makes the device easy to carry and store. One reviewer on r/homelab noted that the charger's ability to charge a MacBook Pro 13-inch up to 46% in 30 minutes was impressive, especially for a device in this price range. The overall build quality and the safety features were also praised, with users appreciating the high-quality polymer material and the inclusion of over-voltage and over-temperature protection.
Where It Falls Short
Despite its many strengths, the Betrusami 120W charger has several notable drawbacks. First, some users have reported inconsistent performance under sustained load, with the device occasionally shutting off or throttling power when multiple devices are connected. Additionally, the retractable cable mechanism has been criticized for being unreliable, with some users reporting jams or failure to retract properly.
Compatibility issues were also raised by several reviewers, particularly with newer MacBook Pro models and certain Samsung Galaxy phones. Some users noted that the device failed to negotiate power properly with these devices, resulting in slower charging or no charging at all. Furthermore, while the device is marketed as a universal charger, it may not be suitable for all high-end devices that require specific charging protocols, which could limit its appeal to power users.
Who It's Best For
The Betrusami 120W USB C Charger Block is best suited for users who value convenience and portability, particularly travelers or those with limited desk space. It is ideal for individuals who own a mix of devices, including iPhones, iPads, and Android smartphones, and who want a single charging solution that can handle multiple devices at once. The retractable cables and collapsible plug design make it an excellent choice for those who frequently travel or need a tidy charging setup at home or in the office.
However, users who require maximum charging speed or compatibility with high-end devices may find the charger lacking. The device is not recommended for users who need to charge laptops or tablets at full capacity consistently, as some reviewers have noted that performance under load is inconsistent. Additionally, those who prioritize reliability over convenience may want to consider alternatives with more robust cable mechanisms or better compatibility with specific device types. The charger is also not ideal for users who already own compatible cables, as it does not include any, and the retractable cables may not be suitable for heavy-duty use.
