Pros & Cons

Pros

  • ✓ Dual rails: 5V/1.5A and 3.3V/1A, jumper-selectable per breadboard rail
  • ✓ Built-in rechargeable battery runs projects with no wall outlet nearby
  • ✓ Two independent channels plus a USB output for powering a second device
  • ✓ 52mm x 32mm x 24mm footprint leaves most of the breadboard free
  • ✓ Works across Arduino, Raspberry Pi, Pico W and ESP32 builds

Cons

  • ✗ Breadboard is not included, so budget for one separately
  • ✗ 1.5A on the 5V rail is thin for a Pi 4 or 5 under real load
  • ✗ Battery capacity and runtime are not listed on the product page
  • ✗ Jumper caps set the voltage, so a misplaced cap can feed 5V to 3.3V parts
