I'm looking for a charging and boost circuit for my portable gaming console. I need it to be able to:
- Charge a 3.7v multi-cell battery pack.
- Boost the 3.7v to 5v for the pi at around 2A
- Hopefully allow it to charge and play at the same time.
I've looked at the Adafruit PowerBoost but the shipping to my country makes it too expensive.
