Wall Power Supply with USB C - 5V 3A Output and Switch

MT3608 Boost Converter Module

PowerBoost 1000 Basic - 5V USB Boost @ 1000mA from 1.8V+

MicroUSB Plug to 5.5/2.1mm DC Barrel Jack Adapter

DC-DC Automatic Step Up-down Power Module (3~15V to 5V 600mA)

5 V buck-boost module. DFRobot lists 3-15 V input, fixed 5 V output and 600 mA max load. Use when the input can sit above or below 5 V, not as a generic wall-adapter replacement.

DC-DC Automatic Step Up-down Power Module (2.5~15V to 3.3V 600mA)

3.3 V buck-boost module. DFRobot lists 2.5-15 V input, fixed 3.3 V output and 600 mA max load. Same family as DFR0569, different output rail.

DC-DC Buck Converter 7-24V to 5V 4A

5 V buck regulator. DFRobot lists 7-24 V input and 5 V/4 A max output. It steps down only, so it is not a boost converter or PD trigger cable.

DC-DC Step Down Buck Converter (6~24V to 5V/16A)

High-current 5 V buck regulator. DFRobot lists 6-24 V input, 5 V output, 16 A max current, low ripple and protection features. Use for heavier loads after thermal and wiring review.

Buck-Boost DC/DC Converter - 8-36V to 12V/6A

12 V buck-boost converter. SparkFun lists 8-36 V input and stable 12 V output up to 6 A / 72 W. It is a converter module, not a plug-in wall supply.

Wall Adapter Power Supply - 9VDC, 650mA (Barrel Jack)

Regulated 9 V switching wall adapter with 650 mA output and 5.5 × 2.1 mm barrel connector. Lower current than the Adafruit 1 A adapter, and not a 5 V supply.

USB Type C PD to 5.5mm/2.1mm Barrel Jack Adapter - 5V

USB-C PD trigger/barrel adapter for 5 V output, up to 3 A depending on the upstream PD supply. Useful for 5 V barrel-powered devices, not 9 V or 12 V boards.

USB Type C PD to 5.5mm/2.1mm Barrel Jack Adapter - 12V

USB-C PD trigger/barrel adapter for 12 V output, up to 3 A depending on the upstream PD supply. Same connector family as the 5 V adapter, different output rail.
