Fast charger. Bigger than expected.
Overall this is a fast charger and is well constructed. The internal fan that blows while charging is a little loud, but it is only on during the charging process to cool the batteries (<15 minutes). I found the charger to be a bit bulky with an AC adapter and the actual charging unit...was expecting something that I plug directly into the wall like my old one. Not sure that I will keep this out all the time given the size, but with a charge of 15 minutes there is no need to let it sit out and plugged in for hours. Don't let these slight quibbles fool you, it is a great charger.
