Treedix 2pcs Breadboard Power Supply Module 3.3V 200mA 5V 2A Prototype Breadboard Equiped with USB Type-C Charging Port, Type-A Output Port

**Editorial Review of the Treedix 2pcs Breadboard Power Supply Module** The Treedix 2pcs Breadboard Power Supply Module is garnering mixed reviews from customers, reflecting a blend of functionality and design Considerations that both impress and frustrate users. For those engaging in DIY electronics and Arduino projects, the module shines with its ability to supply both 3.3V and 5V outputs, making it a versatile tool for prototyping. Many customers report a positive experience in using the module, noting ease of measurement with correct voltage readings and the convenience of solderable pins that fit directly onto a breadboard. However, the product is not without its challenges. Users have pointed out the installation difficulty due to the tight fit required for the 18650 battery, leading to concerns over repeated access. Additionally, the absence of a user manual has resulted in confusion regarding operation settings, particularly when it comes to powering off the unit. Customer reviews indicate that turning the module off requires an extended button press of 11 seconds, a somewhat atypical and unclear requirement for new users. Safety concerns also arise with the lack of reverse polarity protection. This has led to critical incidents where improper connections resulted in damaging the board. The emphasis on battery compatibility, ranging from the preference for alternative battery types (like AA) to complaints regarding the size of the 18650, additionally detracts from the user experience. While the module serves its purpose effectively for powering projects and issuing convenient connections to various devices, the learning curve related to the operational process and safety protocols seems to overshadow its benefits, leaving potential buyers to weigh the Pros and Cons carefully. **
