This charger works great and has no clunky power supply to fool with.
I got this charger to replace a Tenergy charger I used for over a year. I recharge a lot of AA batteries, more than 12 a week on average. The Tenergy worked fine until the wire pulled out of the 12 volt wall power supply. I found another power supply around the house that works but not as well so I bought the EBL charger to replace the Tenergy.  It doesn't have an external power supply. That is wonderful! One less thing to break and have filling up a power strip beneath my desk. The EBL has worked great in the week that I have used it. It seems to be putting a higher voltage in my various NiMH AA and 9 Volt batteries. Display and discharge features seem to work great too.  Two USB ports work when charging batteries or not and very compact.
