Can you charge these off a USB port?
I wouldn't recommend this. For charging you want a source that will initially put out a high current for fast recharging and then detect when the battery is nearing full charge so the charger shuts off and prevents an overcharge. A USB output port just supplies a constant 5V supply so it will initially charge slower than desired and eventually result in an overcharge.
