llano 2-in-1 NP-FZ100 Dual Fast Camera Battery Charger, PD 20W USB-C Charging, Compatible with Sony A7iii, A7R IV, A7R V, Alpha A7C, A9/A9S, A6600, FX3, ZV-E10II

It is extremely convenient and works really well. It charges two batteries quickly, and the built-in power bank is a huge bonus, perfect for shooting outdoors or when you’re travelling and away from sockets. The build quality feels solid, it arrived on time, and it’s very easy to use. Having both a fast charger and a reliable power bank in one device makes it a great addition to my camera kit. Highly recommended!

If you need to charge whilst on the move then this is a good option. I often have back to back weddings where I need to charge during the day. So this is a good option to charge. It also acts as a USB battery pack so it has dual use if my phone needs a top up. It's not cheap and it's not small. But the flexibility makes up for it. If you're a wedding photographer, it's well worth having one in the car for emergencies

This is a charger for some cameras on the market and it is very fast. There is a list of cameras that are suitable and for my son and myself our cameras are on the list. Basically this is a fast charger for certain matching cameras especially when out for the day or in a place that is more remote. Very neat in size and powerful as well. The digital display is very good and clear. Would I recommend it? Yes very much so as I tend to go out to remote areas where the chance of charging would be nil. It is well made and should last for years, Obviously depending on usage. There are extra ports for charging more mundane items such as phones etc. Feels very well made and hopefully will last me for many years. It is protected for over charging. Always nice to be sure. All in all a nice solution to the person on the move.

Charges quickly and useful if away from easy home charging due to built in battery pack.

Great product in concept. In execution I’m a bit torn. The main complaint I have with it is that it is a lot larger than I expected and makes it much larger than carrying an equivalent power bank and dual battery charger separately.

If you’re looking at this charger then you’re looking for convenience and this offers just that. Price: For the price, it’s expensive; but to be able to charge two batteries at home or on the go is super convenient. Performance: I would say performance is so-so when charging the case and two batteries. So don’t rely on it if you’re in a rush. But out and about on full charge you can be sure you’ll have a fresh battery by time the one in the camera has fizzled out. Size: I’d say it’s not as portable as it seems and does take up quite a bit of room in the camera sling. So just be mindful of that for smaller bags. Quality: I’ve had for a couple of months and hasn’t shown any signs of wear or tear. So far it’s holding up completely. It’s good if you’d like convenience.

So bad I sent it back. The charger is fine, does the job of, well, a charger. However, the internal battery takes forever to charge, and its hardly enough to charge 2 batteries. It's also heavy. You're better off just buying 2 more spare batteries and saving on weight.

Does what it says on the box
