I've been using that chargers' little bro - Accucel-6, its a 50watt charger and it does a good job. I have no complaints, mine looks like that one, layout is same, suspect its same charger, just upgraded power capability. It should be a decent charger, has a lot of features. Look around on HC - they have power supplies as well.

You won't beat it for the price. My main charger is a Hypersion 0610iNet, its a 250watt charger, but its also 2x more expensive. Ac/DC chargers all seem to be limited to 50watts, some one announced a new AC/DC model with 70watts, but I don't remember who it was.
