Pro:
Are described everywhere, and I'm generally happy with the charger considering the price. But I want to add some minor annoyances which seem to be generally overlooked:
Con:
No recondition ( but is a cheap charger so not expected)
Charges AAA batteries with too high current (my eneloops get too hot to touch. I prefer not to cook my NiMh)
USB output current is too high ( high current means you can't use full capacity of recycled cells)
Despite the promotional pictures, USB output seem to be using ONLY the right-most slot. You can't load the charger with 4 cells for USB output. Using only one cell for USB output means there is a high current drawn from a single cell which means premature charge cutoff due to voltage drop on old or recycled Li-ion cells.
I have the 202 version and my eneloops don't get hot like that at all.
