Binamao 12V 1.25A 15W Power Supply Charger Compatible with Echo Dot vs JUSTOP Black ATX 500W PSU

Power Output and Compatibility

The JUSTOP Black ATX 500W PSU offers significantly more power than the Binamao 12V 1.25A 15W Power Supply Charger, providing 500 watts compared to just 15 watts. This makes the JUSTOP suitable for powering desktop PCs, whereas the Binamao is designed specifically for Echo Dot and other smart speaker devices.

The Binamao’s 12V 1.25A output delivers 15W, ideal for media players and Echo devices, supporting multiple generations including the Echo Dot 3rd through 5th and Echo Show 5. In contrast, the JUSTOP PSU supplies 500W through a robust ATX form factor, supporting home and office desktop PCs without PCIe connector requirements. This vast difference in power output reflects their distinct use cases: the Binamao is a charger for specific smart devices, while the JUSTOP is a full PC power supply unit.

Device Compatibility and Use Cases

The Binamao power supply is tailored for a broad range of Echo devices including Echo Dot generations 3 to 5, Echo Show 5 (1st and 2nd generation), and even Fire TV Cube Smart Speakers. However, it is explicitly incompatible with older Echo models such as the 1st and 2nd generation Echo, Echo Plus, Echo Tap, and Echo Look. This limits its use to newer Alexa-enabled devices and similar media players.

On the other hand, the JUSTOP Black ATX 500W PSU is intended for desktop PCs, compatible with a variety of brands and models. It does not require PCIe connectors and works with standard ATX 12V systems. Its connectors include 20+4 pin, 4+4 pin CPU power, SATA, Molex, and FDD, making it versatile for many PC builds. Thus, the Binamao is ideal if you need a replacement or spare charger for Echo devices, while the JUSTOP is suited for powering desktop computer hardware.

Safety Features and Certifications

Both products incorporate multiple safety features, but the JUSTOP PSU has a broader set of certifications and protections tailored for PC power supply safety. It is certified by UKCA, CE, FCC, UL, and TUV electrical safety agencies, ensuring compliance with recognised standards. The PSU includes over-voltage, over-power, short circuit, and thermal overload cut-off protections, complemented by Power Factor Control (PFC) for safer power delivery.

The Binamao charger also features built-in protections against over-voltage, over-current, short-circuit, and overload conditions, safeguarding Echo devices during charging. While it does not list external certifications, these internal safety measures help maintain the longevity and security of connected smart devices. Overall, the JUSTOP’s certifications and extensive protections reflect its design for more demanding and safety-critical PC environments.

Physical Design and Build

The Binamao power supply is compact, designed as a travel-friendly charger with a 1.5-metre cable featuring a 4.0mm x 1.7mm DC plug. Its input range of 100-240V and 50-60Hz frequency make it suitable for international use without additional adapters. The cable is described as flexible and durable, resistant to bending and wear, ideal for home or office use with portable Echo devices.

Conversely, the JUSTOP PSU is a full-sized ATX power supply unit measuring 150 x 140 x 85 mm and weighing 1.27 kg. It incorporates a 120mm ultra-quiet black cooling fan with fluid dynamic bearings for efficient thermal management. The PSU’s black flat cables and multiple connectors are designed to fit inside desktop PC cases, emphasising functionality and airflow. While the Binamao prioritises portability and simplicity, the JUSTOP focuses on robust design for desktop systems.

Connectivity and Cable Options

The Binamao charger offers a single 4.0mm x 1.7mm DC plug, compatible with specific Echo devices and Alexa-enabled speakers. Its 1.5-metre power cord is sufficient for typical home or travel scenarios but lacks additional connectors or modular options.

In contrast, the JUSTOP PSU provides a comprehensive set of connectors suitable for desktop PCs. These include a 20+4 pin mainboard connector (540mm), a 4+4 pin CPU power connector (550mm), multiple SATA connectors (six in total across two cables), Molex, and an FDD connector. The cable lengths range from 540mm to 685mm, allowing flexible installation inside standard PC cases. This extensive connectivity makes the JUSTOP compatible with various components, while the Binamao is strictly a single-purpose charger.

Price and Value for Money

Price-wise, the Binamao 12V 1.25A 15W Power Supply Charger is notably more affordable at £9.99, reflecting its role as a replacement or spare charger for specific smart devices. Its price point makes it accessible for users who need a simple, reliable power source for Echo devices without extra features.

The JUSTOP Black ATX 500W PSU is priced at £22.50, more than double the Binamao’s cost. However, this reflects its much higher power output, multiple connectors, and broader safety certifications. For PC builders and upgraders, this price represents good value given the 500W capacity and included cooling solution. Therefore, the price difference corresponds closely to their very different capabilities and intended uses.

Warranty and Support

The JUSTOP PSU includes a one-year manufacturer warranty, providing some assurance of product reliability and customer support. This is a common offering for PC components, recognising the importance of dependable power delivery in computer systems.

The Binamao power supply does not explicitly mention a warranty period in its description. However, its simple design and compatibility focus suggest it functions as a cost-effective replacement charger, typically with standard seller return policies. For users prioritising warranty-backed support, the JUSTOP offers clearer coverage.

Which should you buy?

Your choice depends entirely on your power needs and device type. If you require a charger for Echo Dot or other compatible Alexa-enabled devices, the Binamao 12V 1.25A 15W Power Supply Charger at £9.99 is the straightforward, cost-effective option tailored for those devices. Its compact design and international input voltage make it ideal for travel or home use.

If, however, you are building or upgrading a desktop PC and need a reliable, safe power supply with 500W capacity, the JUSTOP Black ATX 500W PSU at £22.50 offers excellent value. Its broad compatibility, multiple connectors, cooling fan, and safety certifications make it a solid choice for powering various PC components.

In summary, the Binamao is best for smart device charging, while the JUSTOP is designed for desktop PC power delivery. Choose based on your device requirements and power demands.
