the slower rate of charge can/will extend the overall lifespan of the battery. faster your try to charge the overall lifespan can be decreased. you know speed (and th internal heat it causes) can kill.

that is relevant to the charger output capability itself. now the input is from a power supply as seen in the pic) so it is acting as a simple power plug in this type of build scenario so it can accept from other various sources. now with data transfer stuff, things will be "different"
In general with third party chargers and batteries I believe it is safer to buy from B&H as they are not going to sell items that have problems (unlike Amazon). If BH gets returns they stop selling the item, unlike Amazon and its vendors.
Can anyone provide some statistics for charging two 15c batteries? How long does it take and does the charger provide enough power to charge to 100%.
From Nitecore's own information:
Input Voltage DC 5V 2A
Output Voltage 8.4Vą1%
Output current 1000mA (max)
As I stated in a previous post, unless this was some kind of perpetual energy machine, there was no way that it could generate more power than the USB-A input so it will take longer to charge. Assuming that one is charging two 15c batteries with a capacity of 2280 mAhr beginning with a residual charge of 10% (not unreasonable). That's a total power of 4104 mAhr which would need to be supplied. The batteries voltage is 7v and assuming 100% efficiency, one would suspect that a full charge would take on the order of 3.5 hours.

the output parameters are there; and you said it.
it's NOT possible to charge 2 depleted batteries in 2 hrs with the cited output. do you really need actual users data to confirm what you already know?

It is advertised as being able to charge two batteries in two hours and a few posts seem to agree. It would be helpful to know the typical charging time for two nearly depleted batteries. Is it longer than the oem or other available chargers?

i believed others are also questioning the claimed 2 hrs. charge time but no one reported such short charging time for 2-qty depleted batteries. nitecore output is 15% less than the oem charger. i would anticpate at least 2x the charging time of the nikon charger.
I have two of these and have been using them for quite a few years now, for all the different EN-EL15 batteries. It is not fast, but it is reliable.
Did three tests over the last couple of weeks, charging two 15c from depleted to 100%. It takes 4 hours and 40 minutes, +/- 10 minutes. Connected to a 100w wall charger from Satechi with a quality adapter from USB-C TO USB-A.
The two hour claim makes no sense and must be a typo. Not even with two EN-EL15a. At least not to my experience over many years, and the tech specs from Nitecore confirms this.
I know this is slightly off topic, but I found a good, inexpensive battery/power bank that can be used to charge the battery in the Nikon Z camera as well as provide power to the camera. I bought mine on sale plus a 40% off coupon.
TL;dr a power bank that works with Nikon Z cameras.
I think I've heard good reviews on that one, but not sure where.
Is the battery percentage readout accurate on the nitecore charger?
I stopped using my Watson dual charger because it was not showing accurate battery charge, so just picked up a second MH25A. It's such a critical component of a successful shoot to have charged batteries, that I have I prefer not to risk it, and have also stopped using 3rd party batteries.

I bought the Manfrotto version (supposedly identical to the Hahnel).
I put one fully charged EN-EL15C battery into it. The charger spent about a minute counting up to 100% on the display.
I put 2 EN-EL15C batteries into it. The Z7II said the batteries were at 35% and 25% respectively.
Both batteries showed 5% after sitting in the charger for a minute or two. Since the charger begins charging almost immediately, the percent numbers began to creep up very slowly at that point.
I bought it mainly to have a way to charge from the car 12VDC w/o needing an inverter or USB car power supply.
It's nice to know that it can at least identify a fully charged battery from a partially discharged battery.
It saves popping batteries in and out of a camera to find the fully charged ones.
