[3 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] 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

[3 lb] Theres nothing worse than having a shoot slowed down because of batteries. THis is a professional grade charger that works fast and reliably. It might be a little pricy but the time saved on set is well worth it.

[LED] Rather than plugging in 4 separate chargers, this thing gets it done for us with 1 outlet. It is an extreme help on set. Works perfectly with the Canon c300 batteries. I'd definitely recommend this product.

[3 lb] Charges my batteries super fast, faster then the charger that came with my cameras (Ac-160 & Ac-130) I don't know how I survived this long without this charger..? GREAT PRODUCT!

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

[3 lb] Mirrorless cameras eat a lot of battery power, so it's essential to have several batteries on hand and fully charged. This four-station charger makes it easy to keep several batteries ready to go at a moments notice.

[3 lb] I have had this charger for a few weeks now and can say its an excellent device. It's very solid and well built. It charges two batteries in under 2 hours and 4 batteries in about 3. Much easier then single charging several batteries over the course of a day or night for a shoot. It does not come with a car charger but i picked one up directly from the manufacturer (very nice people, quick responses) and can report the charger works just as well, maybe a little slower, through a cigarette lighter. Would recommend anyone who has 4+ batteries and only one charger to pick this charger up.

[LED] A great convenience, especially when yo're using multiple cameras and monitors.

[3 lb] So far it's great. It isn't small, not that I expected it to be, but for home use it's fantastic. I haven't had any issues. It may be the only option, but it's a good one.
