Faster than SONY counterparts
on August 5, 2012
I bought two of these Synergy Digital chargers as a curiosity for for my Nikon (D800) MB-D12 Multi Battery Power Pack (the MB-D12 uses 8 AA (Ni-MH) batteries, which came with these two chargers) to compare against my current SONY counterparts. The chargers, which by the way also charge AAA batteries, are very easy to use with two LEDs indicating status (Red = Charging; Green = Fully Charged). In my first series of picture-taking tests with my D800+MB-D12, these fully-charged Ni-MH batteries powered my Nikon D800 at fast speeds (6 fps) for 1,000+ pictures (I lost count after taking so many test pictures :-)) and still showed about half power levels on the D800; I was very pleased.
I also tested these chargers against my current SONY Cycle-Energy chargers (also bought from Amazon) using SONY Ni-MH batteries; and charging from these almost empty SONY batteries, these chargers easily out-paced the SONY chargers and charged these batteries 2+ hours quicker. I prefer the designs of the spring terminals in these Synergy Digital chargers; they are stiffer and hold the batteries more securely than those of the SONY chargers; hence the batteries do not fall out accidentally; and presumably the stiffer Synergy Digital charger terminals should last longer with repeated use too.
For about 30% less in list price than the SONY counterparts, I believe these Synergy Digital chargers are a great buy. I highly recommend these and I will keeping using them on a regular basis to see how they last long-term.
