[3.25 lb] The pictures don't do this charger justice. This thing is enormous when you compare it to normal single and duel chargers, plus it's metal. The screen is much brighter and clearer than the pictures suggest, and it just feels so much more substantial and looks more professional than any other charger I've ever seen. It performs better too. I mean... I just watched it charge an NP-F970 20% in what felt like five minutes. If you want to be the most reliable guy on set, this charger is a must have. Bite the bullet and get one, you won't regret it.

[3.25 lb] I am a pro shooter who specializes in trade shows and conferences. I recently transitioned from Nikon to Sony A7s due to the extraordinary technology Sony offers along with significantly lighter weight. The trade off, and the only one, is that the smaller mirrorless bodies cannot contain big long-lasting batteries like Nikon and Canon DSLRs. The remedy is that Ive purchased a dozen Sony batteries and at any time I need the ability to recharge four at a time. The TC40 is the perfect solution. It's build quality is tops, it is small and packs easily into my locker. There isn't anything about it that I don't like. Yes it is expensive but I'm willing to pay that cost for the assurance that dead batteries will never be an issue for me on-site.

[4.5 Hours] So far so good. Charged incredibly fast compared to the charger that came with the cam. Absolutely love this thing so far.

[4.5 Hours] Purchased this product for a film shoot in Africa, and it was great. Durable, portable, high powered - it was just what we needed.

[3.25 lb] 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] This charger is needed when you go for a long shooting day and dont have the time to waste time using charger who can only charge one or two batteries at best..... this charger work and rock solid construction

[3.25 lb] We're an organization that has been using individual chargers for years with our DSLR batteries. This device has been a game changer for us. We now always have charged batteries ready to go for those impromptu shoots. We couldn't be more pleased with how this product has helped our workflow.

[4.5 Hours] We in Denmark hire out EX exuiptment and need a super charger the store, two of these did the trick they are working 24/7 and doing its job without complaints!

[3.25 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!

[3.25 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.
