A correct housing and long battery life thanks to the 2600mA of each battery.
This is an EVALUATION REVIEW for SET charger and 2 COMPATIBLE batteries for various ranges of MIRRORLESS cameras and camcorders of the SONY brand, sold on AMAZON with the description:
K&F Concept NP-FZ100 2x2600mAh Battery and Charger, Compatible with Sony A7iii, A7 III, A7iv, FX3, FX30, A6600, A7C, A6700, A7RIV, A7Siii, ZV-E1, ZV-E10ii, Alpha 9 II and A9S.
The fit and load recognition in the camera body are perfect, at least in Sony A7 III and A9 versions. The charger is slow but it is something that seems normal to me, since the batteries support up to 2600 mA of charge and it is a compact and small double charge adapter/controller (an additional power supply is needed to supply it with 5v and at least 2.5 A. of current), a recommended power supply of at least 15 W. of power, either an AC power adapter converter (220v.~240 v. AC > OUT USB-A (with the supplied cable) USB-C/(Micro Usb) if it has a direct output or we have USB-C > USB-C wiring, with 5v. 3A. DC.), or a 12 ~ 24 V. DC vehicle power supply. > Also USB-A (female base) or USB-C wired output, even in travel circumstances without the possibility of an electrical network or vehicle cigarette lighter socket, we could use a POWER BANK of large format and power to power the battery charging adapter. The fact that the charges are slow doesn't worry me much because like most people I suppose I usually leave the batteries charging at night when I don't have the camera in use and pick them up from the charger in the morning, and thanks to this charger I don't have to charge the battery through the camera or charge one and after finishing waiting to change it for the other, I put them both in the accommodation bays and forget about it until the next day. It also has a separate light charge indicator for each battery.
As a compensation for slightly slow charges, we have the advantage that the batteries provide us with very good battery life thanks to their 2600mA/h of charge, providing almost 19 W/h.
Taking into account the good performance they have been providing me for some time and the good selling price of the set, in addition to the trust given to me by this brand (K&F) that I already know and have other items, I have decided that my rating is the highest in its category and therefore I give it: "5 STARS" = [* * * * *].
I hope you find this review useful, happy shopping. Kind regards.: *)
