Raspberry Pi Power Supply vs GeeekPi 18W 5V 3.6A Power Supply for Raspberry Pi 4

Compatibility and Device Support

The GeeekPi 18W 5V 3.6A Power Supply offers broader device compatibility compared to the Raspberry Pi Power Supply, supporting Raspberry Pi 4 as well as older models like Pi 3B+ and 3B. The Raspberry Pi Power Supply is designed exclusively for Raspberry Pi 3 Model B, B+, and R-Pi 2 Model B+, making it less versatile for newer Raspberry Pi iterations.

GeeekPi’s power supply is explicitly tested for Raspberry Pi 4 and comes with a Type-C to Micro USB adapter to accommodate the Pi 3B+/3B models, ensuring flexible use across multiple generations. The Raspberry Pi Power Supply supports multiple current ratings (1A, 1.5A, 2A, 2.4A, 2.5A) but targets older models and does not mention Pi 4 compatibility. Therefore, for users with a Raspberry Pi 4, GeeekPi’s offering is the more compatible choice.

Power Output and Performance

In terms of power output, the GeeekPi 18W 5V 3.6A Power Supply delivers a slightly higher amperage at 3.6A compared to the Raspberry Pi Power Supply’s 3A output. This means GeeekPi’s supply can provide up to 18 watts (5V x 3.6A), which may contribute to more stable performance especially under higher load conditions on Raspberry Pi 4.

The Raspberry Pi Power Supply outputs DC 5V at 3A, which is sufficient for many Raspberry Pi 3 and 2 models but may fall short in scenarios requiring additional power headroom. GeeekPi’s extra 0.6A capacity could accommodate peripherals and higher power demands better. This difference in amperage is modest but notable for users seeking optimal stability and power delivery.

Cable Length and Convenience

The Raspberry Pi Power Supply offers a cable length of 6 feet, which translates to about 1.83 meters, giving users ample room to position their Raspberry Pi without worrying about cord restrictions. GeeekPi provides a slightly shorter extended cord of 120 cm (approximately 3.94 feet).

While both cables provide reasonable length, the Raspberry Pi Power Supply’s longer cable may be advantageous in setups where the power outlet is farther from the device. Conversely, GeeekPi’s cable length is sufficient for many typical desktop or workstation environments, but those requiring extra reach might prefer the longer cable of the Raspberry Pi Power Supply.

Safety and Certification

Both power supplies come with important safety certifications but differ in scope. The Raspberry Pi Power Supply holds ETL, CE, and FCC certifications, indicating compliance with established safety and electromagnetic standards. This gives users confidence in the product’s safe operation and regulatory adherence.

The GeeekPi power supply carries UL Listed, TUV, and RoHS certifications. UL Listing and TUV certification reflect stringent safety testing, while RoHS compliance ensures it meets environmental standards regarding hazardous substances. GeeekPi also features multiple protection functions, including over voltage, under voltage, over temperature, over current, and short circuit protections, enhancing device and user safety.

Overall, GeeekPi offers a more comprehensive set of safety features integrated into the product design, beyond just certification marks.

Additional Features and Usability

GeeekPi includes an ON/OFF switch on the power supply, which adds a layer of convenience by allowing users to easily power the Raspberry Pi on or off without unplugging the device. This can be particularly useful in frequent use cases or troubleshooting scenarios.

The Raspberry Pi Power Supply lacks an integrated switch but compensates with a longer cable and a straightforward plug-and-play design. GeeekPi’s package also includes an adapter to support Raspberry Pi 3B+/3B, adding to its versatility.

For users who value convenience and multi-functionality, GeeekPi’s additional switch and adapter provide tangible benefits not found in the Raspberry Pi Power Supply.

Price Comparison

The GeeekPi 18W 5V 3.6A Power Supply is priced at C$16.99, making it C$2.00 less expensive than the Raspberry Pi Power Supply, which costs C$18.99. This price difference may seem small but could be significant for budget-conscious buyers or those purchasing multiple units.

Given that GeeekPi offers higher amperage, broader compatibility, and additional features like an ON/OFF switch at a lower price point, it represents a more cost-effective choice in this comparison.

Overall Design and Practicality

Both power supplies are designed with practical user needs in mind but cater to slightly different priorities. The Raspberry Pi Power Supply prioritizes cable length and straightforward use for older Raspberry Pi models, featuring a 6-foot cord for flexible setup.

GeeekPi’s design focuses on enhanced power delivery, safety features, and user convenience with an integrated power switch and multi-adapter compatibility. This makes it more suitable for users running Raspberry Pi 4 or who require quick power control and protection against electrical faults.

Both products maintain industry-standard input voltage ranges (100-240V AC), ensuring global usability, but GeeekPi’s additional features and certifications suggest a more robust and thoughtful design.

Which should you buy?

If you are using a Raspberry Pi 4 or want a power supply with a higher current rating (3.6A vs 3A), additional safety protections, and an ON/OFF switch for convenience, the GeeekPi 18W 5V 3.6A Power Supply is the better option. It also costs less at C$16.99 and supports multiple Raspberry Pi models with included adapters, making it a versatile, cost-effective choice.

However, if you primarily use older Raspberry Pi models such as the 3 Model B or 2 Model B+, need a longer cable (6 feet), and prefer a power supply certified by ETL, CE, and FCC, the Raspberry Pi Power Supply at C$18.99 remains a solid, reliable selection.

In summary, GeeekPi’s power supply edges ahead with superior amperage, multi-protection features, and lower price, making it the preferred pick for most Raspberry Pi users, especially those with newer models.
