We recently bought a new Sony battery charger to use with both our older Sony NP-FW50 batteries and our newer NP-FZ100 batteries. We wanted one device that can charge two batteries at a time and with the NP2 charger we can do that but also charge both our older FW-50 batteries and our newer NP-FZ100 at the same time, plus have the option to charge the NP-BX1 batteries that the RX100 series uses.
If you are like us and have different Sony cameras with different types of batteries, the NP2 is, at least on paper, one of the best options around. Here is some general information and specs on this charger:
- The NP2 has no less than 7 major protections including over-current, over-charge, over-capacity, over-temperature, over-discharge as well as abnormal battery monitoring and abnormal internal resistance monitoring.
- Patented stackable battery compartment design with two independent charging channels, supporting multiple ways of hybrid charging.
- LCD panel (IPS) with battery parameters including charging state and Internal battery performance as well as the health status of each battery.
- USB Type-C power input with a maximum support of QC 3.0 18W quick charge.
The charger is really small at 11cm (4.5″) over 9cm (3.5″) and is made of fairly light plastic. It has a USB-C port on the back and two buttons on the front next to the LCD.
Is the NP2 the ultimate Sony battery charger?
Please note that the charger comes with a USB-C to USB-A cable but no wall charger so you will either need to connect it to a computer or use a good quality wall charger (it seems to work with both USB-C and USB-A chargers although in the case of USB-C to USB-C you will need to provide your own cable). On the plus side it does seem to charge fine from our Anker USB power bank so you can charge batteries on the go as well.
Placing a battery in one of the charging ports will provide you with a lot of technical information which includes the type of battery, its charging status, how long it has been charging, and how much power was delivered to it as well as temperature and a few other bits of info. If you leave the battery in for a few seconds the charger also ranks it with 1 to 5 stars based on the cell status (we are not sure how accurate this system is but it’s nice, some of our third-party batteries got 3/5 while our original Sony batteries got 5/5).
One other small feature is a beeping sound whenever a battery is placed in the charger or one finish charging. We like this since you can audibly tell when the battery finished charging although it might annoy you if you are going to bed in a hotel and it beeps in the middle of the night.
We had at hand both NP-FZ100 (Sony originals) and NP-FW50 batteries (both originals and third party units).
For each type of battery we tested the time it took to charge both a single battery and two similar batteries at the same time and here are the results:
- A single NP-FZ100 battery took – just under 4 hours to fully charge [In camera – using USB-C and a fast wall charger (220v) it took about the same time].
- Two NP-FZ100 batteries took – just over 5:30 hours to fully charge.
- A single NP-FW50 battery took 1 hour and 55 min to fully charge [In camera using micro USB and a fast wall charger (220v) it took close to 4 hours].
- Two NP-FW50 batteries took close to 2 hours to fully charge.

So as you could see from our testing, the NP2 isn’t necessarily the fastest charger on the planet, but it is certainly convenient and flexible in many respects, and for $35 it is pretty much a steal for anybody looking to charge multiple Sony camera batteries of different types.
