Llano Voltcase Cs2 NP-FW50 Battery & Charging Case Kit for Sony Cameras

It’s more expensive than the other options but it’s worth it. High quality, great design, fast charging. I really struggled with the price but it’s actually worth the extra money. Very happy with this item.

Great battery life and quality! Very happy with this and comparable with my Sony ZV-E10.

So this is NOT a portable power bank charger. IT WILL NOT CHARGE BATTERIES IF IT ISN'T PLUGGED IN. I thought it would, but that's on me as a consumer. I should have read the descriptions, watched the videos, and browsed through the reviews more thoroughly. In any case, I'm not upset about it at all.This is such a cool little gadget. It's effectively just a fast charging dual camera battery charger and a case. It has two slots for batteries and two SD card slots that have the SD cards click into place with a push (which I love). Basically just consolidates all your essentials into a nice, good quality little case when it's not plugged in. Excellent design, nice and minimal, not too big. A necessary part of my kit.Mine came with two NP-FW50 batteries for my Sony a7 [mk1] camera. If I know I'm going to go out for a long day of photography, I can pretty quickly charge two different sets of batteries for a total of four batteries the night before and be more than well-equipped for the next day. When I'm ready to go, I drop it into my camera bag and I'm on my way.Pretty neat. Five stahs.

These batteries work very well and the charger case is genius!

Charger works great. I like the percentage displays. Those work even if the charger is not connected to a power source. It will use power from the inserted batteries to make that feature work. This leads to the one thing that is a disappointment for me concerning this charger. If you leave batteries in it and the charger is not connected to a power source, it will discharge the batteries slowly. This defeats the purpose of using the charger to store the batteries. I thought to myself... "no problem, I'll just flip the batteries around so there is no electrical contact and close the lid. The problem there is that the lid won't close fully in that situation. So, for me, the charger cannot also be used as a storage case for the batteries. To keep the battery contacts protected, some other storage method will be needed.
