Pros: * Will not try to charge already charged batteries (LED becomes green as soon as you insert a charged battery)
* Gently charges the batteries - does not overheat them. In fact, they are just a little warm during charging.
* Has dual power-in - either from the regular 220/110V power outlet or from a 12V source (e.g. car power).

Cons: * It does not use a specialized IC like bq24105 or bq25012, so don't expect it to be too smart (e.g. it can't do droplet-charging for overdischarged unprotected batteries).
* Does not use a temperature sensor (at least I haven't found one), so it won't stop charging even if your batteries will be in flames.

Other Thoughts: The charging current is about 0.33A, so it'll take about 7-8 hours to charge a 2400mAh 18650. The good side is that the battery is very unlikely to overheat with such low charging currents, and will wear out slower (will resist more charge-discharge cycles).

Bottomline: A good charger for everyday use, though not the silver bullet (ack!).

Pros: -Build Quality pretty good does not feel cheap at all.
-Charged Ultra Fire Protected battery 16340 cr123a up to 4.2v, this is incredible.
-2 Separates power source, have not test with cigarette plug on card adapter for 2nd power source
-Price is 3 times cheaper than brand name Li-ion chargers.
-Plug is very soft, easy to bend into 45 degree and use with Australia standard power point, Aus buyers don't buy any adaptors...this will do the tricks.

Cons: nothing i can think of....

Other Thoughts: They all come with us standard plugs, hope they have AUS standard plugs and i don't have to bend 2 pins into 45 degrees angle to fix my power point...

Bottomline: I bought 1 , just order 1 more for back up , just in case in one die and i still have back up.....

Pros: Great price!(preço excelente);
This charges your batts at low speed (carga lenta que não danifca as baterias);
Don´t warm the batts (não aquece em demasia as baterias, preservando a vida útil das mesmas);
Cut off voltage at 4.2V, mesuared with multimeter (corta a carga com 4.2V medidos por multímetro, não dá sobrecarga);
The strong spring system helps to get the batts without damage the bottom side(o sistema de molas reforçado ajuda a prender as baterias sem estragar a parte de baixo (-) das mesmas)

Cons: I really don´t have any negative word to say about it (sinceramente não vi nada de negativo a ser dito)

Other Thoughts: I had one for 2 years and I took it to one friend that is very happy. Now I´m getting a new one. Then you can get easy that is so good (eu tinha um destes por 2 anos e eu passei pra um amigo que está muito feliz. Estou comprando outro, logo, pode ficar tranquilo que o carregado é bom)

Bottomline: By this price none here in Brazil(por este preço não encontra nada aqui no Brasil).

Pros: - charges slowly (will not kill your batts)
- runs cool
- works well on 14500 and 18650, takes em right up to 4.2 volts
- feels well made
- very strong springs
- charges pretty much any size
- no tedious solder or paper clips required to charge your batteries
- reverse polarity protection (the ultrafire version dose not have this feature)
- Oh yeah, it's a cheap price

Cons: - charges slowly (you must be patient)
- not really anything bad to say about this one, I'm getting a few more :)

Other Thoughts: Green LED is charged, Red LED is charging, orange LED (really just some green and some red, so it "looks" orange) means probably the protection circuit is kicking in and out to prevent over charge (circuit in battery I think want to stop at 4.11 - 4.13 volts and the charger wants to take em up to 4.2), while the charger goes from charging (red), to charged / no battery in slot (green). If you see an "orange" LED, then your battery is charged.

Bottomline: if you need a charger that charges anything/everything, BUY THIS CHARGER, besides, it's cheap as hell :)
all the other chargers here from what I understand (reading reviews), must be modded in order to charge everything, or cannot charge other than 16340 and 18650, or blow up (I think it's a euro prob, the 240 volt instead of 120), or usually a combination of these extreme cons.
