Receieved this product as a part of the Amazon Vine program to test our and review, these are my honest thoughts. Historically, I've always been very pleased with K and F Concept products. I own numerous lens filters, and camera bags by K and F. I was excited to test out the portable charger for Sony NP-FZ100 batteries. I own and use a Sony A7iii and it's always handy to have a portable charger/holder in your camera bag along with extra batteries. As all K and F products the the packaging was well presented, and the build quality was excellent. I immediately tested out the charger - which connects to your power source via USB-C - on my two A7iii batteries. They fit snugly and immediately started charging. The charger has a power display which shows how full the batteries are charged which is handy. The holding tray doubles as a carrying case to which the batteries themselves snap in and stay inserted. You remove the tray by pressing a button and sliding it off the charging base unit. The charger also included a soft, lovely leather bag intended for carrying the instructions to which I will likely use to carry lens filters. K and F always seems to send extra bonus items with their products such as cleaning clothes and in this case a premium feeling bag. I am very happy with this case/charger combo. I think the only way to improve upon it would be for the unit to double as a power supply and carry a charge internally for on the go charging. However, if you travel or go to shoots with a power bank you can plug this in and carry it in your backpack, car, or camera bag without any issues.

Better than all others. Actually charges to 100% (unlike others) and in decent time. Acts as a carrying case of sorts for two batteries if you want which is nifty.

Charging is faster than expected and easy to use.

After all, charging 2 devices at the same time is convenient. What's more, the SD card slot is also surprisingly practical. Since it is placed vertically, it doesn't take up much space. I haven't confirmed whether the charging status% display is really correct, but it's definitely easier to understand than the 3-4 point indicator, so this alone is worth buying. There are no operational issues.

This is a good quality charger which is not only useful for the charging but also to store extra batteries while travelling.

It is easy to use. Just attach the usb-c wire to the adapter and you are good to go.

It works well for the Sony camera batteries.

On the addition of has a space to store the memory cards.

The digital display tickles men's hearts; it looks like it's properly displayed
, so there's no sense of incongruity; it's slimmer than the one up until now, and since it's arranged so that the depth can be made compact, Cinderella fits in a small space in front of the PC on the desk and raises tension. There are no particular complaints about performance ⭐ ︎ 5
