This K&F Concept USB battery and charger is just what you need if you take a lot of pictures. (And it comes with two batteries.)

this is a great value item compared with the expensive original one, the only difference is the battery indicator, but this is an amazing spare option and cost half of the price

Two batteries and a double charger for $25.99 offered by K&F Concept... you cannot beat that. Not to mention, they are fully decoded as described. I charged my batteries, popped one into my Canon T7i, and it didn't miss a beat. You'd thought I put a Canon OEM battery inside. I highly recommend these batteries.

Good value for the price.
Battery life on my M5 is about 500-600 shots before the red blinking warning starts (my canon battery is 800-900 shots despite what the reviews say). That's with an auto-focus lens and a mixture of screen and viewfinder. (no video) It lasts longer if I'm using a fully manual lens and a bit less if I'm using my 55-200 autofocus lens with image stabilization.
What I love: USB charging! Fast to charge, easy to stuff an extra battery or two in my pack, keeps the charge without having to worry.
What I don't like so much: It doesn't tell the camera how much charge is in the battery until it's almost empty.

The batteries came half charged so I used the charger overnight to charge them to 100%. I then left both batteries for a few days before testing them with my Sony camera. Both batteries showed a charge of 100%.
One of my earlier third party NP FW batteries had a habit of slowly draining at about 1% per day when not in use and the camera was not in use, while another set completely failed within a year of use. This seems to hold the charge well for the time being. If I see problems I will update here.
As mentioned in the title of my review, the charger can be conveniently connected via a typical USB connector as well as a newer format (USB-C). The lights correctly indicate whether the battery is charged or not, and other brands of NP-FW50 batteries can be used.
Overall very good quality and no problems so far.

These work as advertised. They show up as “NH” batteries in an R5, so they unlock the power features including USB charging in the case. The charger also works well but only uses conventional power even when connected to a PD power supply. So don't expect fast loading.

I have a lot of generic batteries and some fit well and some don't. Some were DOA and others were the last of my original Canon batteries. So far these feel like a winner. They charge quickly and hold a good charge.

Two pack set batteries and charger for my canon rebel. This charger is much more efficient than the one they give you with your camera and flatter too. Double slotting allows me to charge more and faster and anywhere I want since it's completely portable with the usb.

The battery life is great. The only downside is that the battery meter display never moves off full on my t7i.
