USB Charging Circuit
A handy DC to USB assembled circuit that we use to make our Altoids USB chargers. You can use it too. Takes DC power from as low as 2V and bumps it up to the 5V USB needs at around 600mA (0.6A) of current.
- Apple Products (we don't recommend using it with iPads)
- Garmin GPS
- Android Phones
- Arduino and Arduino Clones
- To be honest, most anything that charges with USB
- Note: While it will send power to a tablet, it'll be too slow to make much of a difference. You won't be happy with outcome.
