CanaKit 3.5A Raspberry Pi 4 Power Supply vs CanaKit 45W USB-C Power Supply with PD for Raspberry Pi 5

Price Comparison

The CanaKit 3.5A Raspberry Pi 4 Power Supply is priced at $9.99, while the CanaKit 45W USB-C Power Supply with PD for Raspberry Pi 5 costs $15.77. This means the Raspberry Pi 4 Power Supply is about 37% cheaper than its counterpart. With a substantial price difference of $5.78, budget-conscious users may find the Raspberry Pi 4 Power Supply more appealing, especially if they only need power for the Raspberry Pi 4. However, the higher price of the Raspberry Pi 5 Power Supply could be justified by its advanced features and compatibility with multiple devices.

Design and Build Quality

Both power supplies are designed with quality in mind, but they cater to different needs. The CanaKit 3.5A Raspberry Pi 4 Power Supply features a thick 18 AWG cable with a length of 5 feet, ensuring durability and a good reach. In contrast, the CanaKit 45W USB-C Power Supply has a slightly shorter 4-foot cable but still maintains sturdiness with its thick insulated design. Both products are UL Listed and include noise filters for added stability, ensuring reliable performance during use.

Compatibility

Compatibility is a key differentiator between the two power supplies. The CanaKit 3.5A Raspberry Pi 4 Power Supply is specifically designed for the Raspberry Pi 4, making it a dedicated option for users of that model. On the other hand, the CanaKit 45W USB-C Power Supply is compatible with both the Raspberry Pi 5 and 4, in addition to being able to charge other USB-C devices such as mobile phones and tablets. This makes the Raspberry Pi 5 Power Supply a more versatile choice, especially for users who may upgrade their Raspberry Pi in the future.

Power Output

When it comes to power output, the differences are significant. The CanaKit 3.5A Raspberry Pi 4 Power Supply delivers a steady 3.5A, specifically designed to meet the needs of the Raspberry Pi 4. In contrast, the CanaKit 45W USB-C Power Supply boasts a maximum output of 45W, with a standard delivery of 5V / 5A (27W) tailored for the Raspberry Pi 5. This higher power output allows users to connect additional devices and utilize advanced features, such as "Super Fast Charging" and Power Delivery modes, making it more suitable for power-intensive tasks.

Additional Features

Both power supplies incorporate beneficial features, but they excel in different areas. The CanaKit 3.5A Raspberry Pi 4 Power Supply includes a noise filter for improved stability, which is crucial for consistent performance with the Raspberry Pi 4. The CanaKit 45W USB-C Power Supply also features a noise filter and adds Power Delivery (PD) support, allowing for dynamic power management. This makes it a more advanced choice for users who require flexibility in power delivery when using various devices.

Cable Length

The cable length can influence user experience based on individual setups. The CanaKit 3.5A Raspberry Pi 4 Power Supply offers a generous 5-foot cable, providing ample reach for various setups, especially if the Raspberry Pi is placed away from power outlets. Conversely, the CanaKit 45W USB-C Power Supply has a slightly shorter 4-foot cable, which may limit placement options. While both lengths are reasonable, the longer cable of the Raspberry Pi 4 Power Supply could be more convenient for some users.

Target Audience

These two power supplies target different user bases. The CanaKit 3.5A Raspberry Pi 4 Power Supply is aimed at users who specifically own a Raspberry Pi 4 and need a reliable, cost-effective power solution. It is ideal for hobbyists or anyone looking for a straightforward power option without needing additional features. In contrast, the CanaKit 45W USB-C Power Supply is designed for users who may have upgraded to the Raspberry Pi 5, or those who require a higher power capacity for multiple devices. Its versatility makes it suitable for a wider range of applications beyond just powering a Raspberry Pi.

Which should you buy?

Choosing between the CanaKit 3.5A Raspberry Pi 4 Power Supply and the CanaKit 45W USB-C Power Supply ultimately depends on your specific needs. If you're looking for a budget-friendly option specifically for the Raspberry Pi 4, the 3.5A power supply at $9.99 is a solid choice. However, if you foresee needing more power for additional devices or plan to upgrade to the Raspberry Pi 5, investing in the CanaKit 45W USB-C Power Supply for $15.77 could be worthwhile. Its versatility and higher power output make it an excellent long-term investment for users with broader power needs.
