Use the 3V out when running 3.3V logic, replaces 2 AA’s
4.5V will drive most 5V electronics just fine, or replace 3 AA’s
6V replaces 4 AA’s, with a 1n4001 in series it will give you a bit over 5V out
7.5V goes into most linear regulators with minimal dropout
9V as well, and also replaces a 9V battery
12V will drive many small DC motors and steppers.
Up to 1000 mA at any voltage! Chances are this can replace any of your power plugs and work as a portable, low cost bench-top supply. Only for use in 120V countries, if you have 220V you’ll need a transformer. US 2-prong plug that folds back. Comes with 6 common plugs.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

For those of you who aren’t aware, 1000mA = 1 Amp. I point this out due to the fact that there seems to be a frequent attempt here to quote large numbers without simplifying the units. Just take a look at the lipo batteries for further examples.
