There seems to be no difference between those batteries and the OEM ones in terms of longevity. The additional way of charging by USB C is a great little convenience that help a lot when traveling light, or simply when the original Canon battery charges via the cradle charger and you want both to be ready quicker.

After using them for a while on a Sony A6700, we can say they meet all our expectations. They're durable, and when you're in the countryside or mountains, you can easily charge them with a power bank.

Compatible with first-generation Canon R. Very convenient USB charging. Everything OK

Nothing to say, it's an excellent product! Really!

These have been great for travel where I don't want to carry a full battery charger. The only downside is that I would say they don't always charge in a charger designed for these batteries, but if you use the USBC interface, they fully charge and work great.

Used this on my SOny Z190 camcorder. works great for me.

Love these batteries, they are really good since I use live view a lot with my canon 90D. The charging is fast and reliable. I highly recommend it to other photographers to use these batteries. I am a nature photographer and I recommended my friend who is a sports photographer. The cost of these batteries are good and not overly expensive.

The K&F NP-F100 battery offers a nominal capacity suitable for cameras that use this type of battery, providing a battery life comparable to the original. Its most notable feature is the addition of a USB-C port for direct charging, which represents a significant improvement over previous models that used micro-USB ports or dedicated external chargers.

The USB-C port allows for faster and safer charging, with support for regulated direct current (DC) charging, which optimizes recharge times. However, it is essential to use a dedicated charger compatible with the battery's electrical requirements—particularly in terms of voltage and amperage—to avoid damage or inefficient charging. Using generic chargers or those with inadequate specifications can affect the battery's lifespan or even compromise its safety.

The physical construction of the USB-C port is robust and designed to minimize wear and tear from frequent insertion. Furthermore, the battery includes overload and short-circuit protection, contributing to its reliability.

In short, the addition of a USB-C port on the K&F NP-F100 significantly improves the charging experience, provided you use a charger that meets the recommended specifications to ensure optimal safety and performance.

These batteries are monsters. Convenient charging, long lasting, and priced competitively.

Good capacity, easy to charge when on the go. Good value for the buck.
