Security-01 DC 9V 1.5A Power Supply vs GeeekPi USB-C Power Supply UK Plug for Raspberry Pi 4 With On/Off Switch

Overview

When it comes to powering devices, choosing the right power supply is crucial. In this comparison, we will look at the Security-01 DC 9V 1.5A Power Supply and the GeeekPi USB-C Power Supply, which is specifically designed for the Raspberry Pi 4. The former is priced at £9.98, while the latter comes in at £11.99. Each of these products has unique features that cater to different needs and devices.

Compatibility

Compatibility is a key factor when selecting a power supply. The Security-01 power supply is versatile, working with a variety of devices such as Schwinn elliptical machines and Arduino boards, as well as many 9V projects, provided they do not exceed 1.5A. However, it is important to note that it only functions with devices that require a centre positive polarity, making it unsuitable for various effects pedals and keyboards.

In contrast, the GeeekPi power supply is tailored for the Raspberry Pi 4, supporting models with 1GB, 2GB, 4GB, and 8GB RAM. It also includes a USB-C to Micro USB adapter for compatibility with older Raspberry Pi 3B+ and 3B models. This specificity in design makes the GeeekPi a more straightforward choice for Raspberry Pi users but less versatile for other applications.

Power Output

The Security-01 power supply delivers a 9V output with a current of 1.5A, making it suitable for devices that require a higher voltage. This power level is adequate for various household devices and compatible electronics, which may demand more than just standard power supply levels.

On the other hand, the GeeekPi USB-C power supply provides a 5V output with a higher current capacity of 3.6A. This allows it to deliver a total of 18W, ensuring that the Raspberry Pi 4 operates efficiently. While it may not cater to devices that require 9V, the higher current output is beneficial for powering the Raspberry Pi and keeping it stable during operation.

Build Quality and Safety Features

Both power supplies offer a level of safety features that enhance their usability. The Security-01 power supply is built with a focus on durability, but detailed safety specifications are not mentioned in its product description. It is crucial for users to ensure that their devices are compatible with its centre positive polarity to avoid damage.

Conversely, the GeeekPi power supply is noted for its professional certification, including UKCA and RoHS, which speaks to its quality and safety compliance. It features multiple protection functions like over-current, short-circuit, and over-voltage protection, making it a safer choice for users who prioritise device safety.

Cable Length

Cable length can considerably impact the usability of a power supply. The Security-01 comes with a 2-metre cable, providing ample reach for many household setups. This length allows users to position their devices without being constrained by short cables.

In comparison, the GeeekPi supply has a slightly shorter 1.2-metre cable. While this is still functional for many setups, it may require users to position their Raspberry Pi closer to a power outlet or use an extension cord in some situations. The longer cable from the Security-01 gives it a slight edge in flexibility.

Usability Features

Usability features can greatly enhance the user experience. The Security-01 power supply lacks any additional usability features, focusing solely on its basic function of power delivery. It is straightforward but may not cater to users looking for enhanced convenience.

The GeeekPi power supply stands out with its integrated on/off switch, allowing users to easily power their Raspberry Pi on and off without unplugging the adapter. This feature adds a layer of convenience, especially for users who frequently need to restart their devices or switch them off when not in use.

Price Comparison

The price difference between the two power supplies is notable. The Security-01 is priced at £9.98, making it the more affordable option for users seeking a basic power supply. This lower price point might appeal to those who need a power supply for devices that require 9V.

In contrast, the GeeekPi power supply is priced at £11.99, which is a £2.01 premium over the Security-01. However, this price reflects the added features and certifications that come with it, particularly for Raspberry Pi users. The choice here depends on whether users prioritise cost or the additional benefits that come with the higher price.

Which should you buy?

Deciding between the Security-01 DC 9V 1.5A Power Supply and the GeeekPi USB-C Power Supply ultimately depends on your specific needs. If you require a power supply for a variety of devices that operate at 9V and appreciate the longer cable length, the Security-01 is the right choice. However, if you are a Raspberry Pi user looking for a reliable power supply with safety certifications and an on/off switch, the GeeekPi is worth the extra cost. Each power supply has its strengths, making it important to align your choice with your intended use.
