It is a project of a charger that supports cells 18650. The housing was taken from a cheap charger, which removed board is presented on the photo below:
Then a new board was designed and digested for MAX1811 systems. The board does not include a power supply, because it is powered by a 5V/2A plug.
The USB socket was added, which was connected to +5V, what made it possible to charge different devices without the need to connect them to a computer or charge an accumulator Ni-MH AA and AAA with a small Sanyo charger.
