[0.15 lb] Metal base is solid, but not too heavy. Batteries easily slide and lock into place on the charger. Two simple LEDs show if it's charging or finished. Use it with my Sony and SWIT BP-U batteries. I will definitely consider more Dolgin products in the future.

[0.15 lb] I would encourage everyone to get one of these chargers and make your life easy! This thing charges way faster than the camera charger and does 4 at once. Now we always have charged up batteries ready to go. You don't have to worry about leaving them on the charger too long either!

[Black] I had bought two previous two position chargers from lesser brands and both were just cheap and poorly made. combined they cost the same as this 4 position high quality charger I am using on set right now

[4 x 2.5 x 0.5"] This is the second Dolgin unit I have purchased. I have another that is 5 years old and still working as new. Expensive but you definitely get what you pay for in this instance.

[4 x 2.5 x 0.5"] This is a fantastic charger. It is sturdy and charges fairly quickly. I think its a good compromise between the cheap options and the more expensive ones.

[0.15 lb] I don't know how much everyone knows about the parrallel and series response of batteries but to use a pair of NP-F's to create a vmount or a(gold mount) equivalent you are going across a paralell and a series circuit. The general rule of thumb is to marry lithium batteries because the downstream cell has a bigger draw. So pair the cells and charge at the same time and swap positions. This gets harder in the np-f line when a pair becomes a combined cell. But I read what dolgin has commented on, he is aware of this and made sure this charger accounted for it, even if it did not have to, the mindfullness is enough for now so I bought his stuff.

[4 x 2.5 x 0.5"] So far so good. Charged incredibly fast compared to the charger that came with the cam. Absolutely love this thing so far.

[Black] I guess this is a matter of you get what you pay for. It's either $30 chargers off of amazon which are extremely unreliable or $200 chargers like this one. I appreciate that it is made out of metal, other than the receivers for the batteries. Does exactly what it says in the description. Charges 2 bp-750s in 4 hours. With that I can run my Komodo indefinitely on 3 batteries.

[4 x 2.5 x 0.5"] Switched to the charger from another brand. This one is solid, great for charging 4 batteries at a time. No issues across 3 different battery brands, Canon BP, RED Volt by Core and Blueshape BP. Highly recommend. Sturdy build too.

[Black] This product is expensive but the best Sony NP battery charger I have. The other chargers are so slow and this one charges two at once.
