Proper storage and long battery life thanks to each battery's 2600mA.
This is a REVIEW for a charger set and 2 batteries COMPATIBLE with various ranges of SONY mirrorless cameras and camcorders, 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 recognition of the charger in the camera body are perfect, at least in the 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 small compact double charging adapter / controller (an additional feeder is needed to supply the 5v and at least 2.5 A. of current, recommended feeder of at least 15 W. of power, either an AC converter feeder from the electrical network (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 feeder. > Output also USB-A (female base) ö USB-C wired, even in travel circumstances without the possibility of an electrical network or vehicle cigarette lighter socket we could use a large-format and powerful POWER BANK to power the Battery charging adapter. The slow charging doesn't worry me too much because, like most people, I usually leave the batteries charging overnight when I'm not using the camera and remove them from the charger in the morning. Thanks to this charger, I don't have to charge the battery through the camera or charge one and then worry about swapping it for the other afterward. I just put both in the charging bays and forget about it until the next day. It also has a separate charge indicator light for each battery.
In return for the somewhat slow charging, we have the advantage that the batteries provide very good battery life thanks to their 2600mA/h charge, providing almost 19W/h.
Considering the good performance they've been providing for some time now and the good selling price of the set, in addition to the confidence I have in this brand (K&F), which I already know and have other products from, I have decided to rate it as the highest in its category. I award:
"5 STARS" = [ * * * * * ].
I hope you find this review helpful. Happy shopping. Best regards. :*)
