Approaching kryptonics: a charging head to satisfy your pleasure

"Approaching kryptonics" is an evaluation report column of "true evaluation and actual measurement" launched by "open case dog". Talk about "how to spend money on shopping" and "subjective and real feelings after product experience"( I like the image quality of Canon and the portability of Sony. Why not "double repair of Canon"

At the end of the year, I got into a second-hand Sony 6300 camera, which has been used for several days. The advantage is that it is light, portable and small. The most unbearable thing is its battery capacity. After taking a photo for a while, it's dead. I'm very anxious with three batteries( Before using Canon 5D2, I never worried about the power problem.)


I bought and assembled a battery and gave it a charger. I always felt that the charging was a little slow. The old-fashioned micro interface is very troublesome, and it needs one more cable. We see that a very innovative modular charger, xtar vn2 intelligent display function charger (hereinafter referred to as ASDC vn2 charger), has been developed by ASDC, which can charge the batteries of Sony micro single / SLR and Canon micro single / SLR. It's very suitable for the photography lovers of "Jiani Shuangxiu".

Packaging & Accessories

Because now I mainly use Sony micro single, I bought a vn2 head + np-fw50 base. The front of the package is a hollow window design, which can directly see the appearance of the product, and the back is the parameters and precautions of the charger. The design of ASDC is relatively fresh, there is no miscellaneous design, everything speaks with products.


The package contains a charging head, a base, a data cable and a manual. The quality of the data cable of ESDA is very good. It's a custom-made, standard silicone line.

Appearance & Performance

The front of the charger looks smart and round, with xtar's silver logo, a small display and two np-fw50 battery slots.

The back is the parameters of charger, input power 5V 2.1a, output is 8.4v 1A * 1 / 0.5A * 2. At the bottom is a type-C charging interface, regardless of square, plug and play, it is very convenient.

Isn't the ESDA vn2 charger a module charger? What about modules? It's all one design, isn't it?

The original mechanism in the charger side, there is a unlock key.

Just push this button up. You can take apart the charging head and base.

The six contacts of the base are quite large. The six probes of the charging head are a little thin! The elasticity of the probe is OK when it is pressed up, so we expect its durability performance in the future.

The size of ESDA vn2 charger is similar to that of micro single battery.

The battery is charged vertically, so it can be controlled less.

Connected to the power bank, you can charge the battery. The OnStar display is a TFT monochrome screen, which will reflect light in the sun. It can actually see the reading, but it can't be photographed.


At this angle, I can barely get a shadow.

In fact, the role of the display is not big, there is no practical reference significance in daily life. However, when the battery is old or brand-new, the role of ESDA vn2 is very big. It can detect the attenuation of the old battery to determine its actual battery capacity, how long it can withstand, and whether to replace it with a new battery. The new battery can check the reading to confirm whether the capacity is virtual and whether it is an old battery with renovated appearance, so as not to affect the normal use of the camera.

Six battery information can be seen on the display screen of ESDA vn2 charger. The top left is the battery slot and the top right is the battery capacity. The middle four are battery temperature, charging capacity, battery voltage and charging current. If the two slots are charged at the same time, the battery slot information will be switched at an interval of 2 seconds.

The embarrassing thing is that there is no card slot 1 / card slot 2 on the base, although the experiment shows that the card slot 1 is close to the charging head.

ESDA vn2 charger adopts advanced three-stage charging, which optimizes the charging mode. Compared with the previous pulse charging, the charging is more stable, the efficiency is higher, and the service life of the battery can be extended.

Compared with the charger I used before, the volume of vn2 is reduced by twice, the weight is reduced by 6G, and only the thickness is increased by 4.5mm.

What's more powerful is vn2's replaceable base design. With one head and several bases, it can meet the needs of multi camera shooting. It's a must for lovers of "Jiani weekend"! The only possible concern is whether the telescopic probe of the charging head is durable enough.

In addition to portability and convenience, the most important thing to buy a charger is safety. Safety is divided into two points: one is the health of the battery, which will not overcharge and overheat; the other is the safety of people, which will not shock the human body or short-circuit fire due to excessive current. As a charger, estag has a deep foundation and valuable experience in this field. Vn2 has built-in intelligent integrated chip, with six protection functions (reverse connection protection), which can be used safely.

User experience

Vn2 has been used for some time, and the biggest feeling is that it is light and portable, which makes a lot of space for the narrow photo bag. The charging speed is fast. Compared with the previous charger (input 5V 2.1a, output 700mah * 1 / 500mah * 2), the charging speed of single charger is 30% faster, and the charging speed of double charger is basically the same. The charging temperature is a little lower, which doesn't rule out that the shell is thicker and the feeling is not strong. Its biggest feature is the replaceable charging base, which I haven't experienced before. I'll try to buy a base of Canon SLR (lp-e6) in a while.


ASDC vn2 intelligent display charger, small appearance; Type-C charging interface, very convenient; It can charge two batteries at the same time and double the efficiency; Charging speed is 30% higher than other chargers; With screen display, the battery information can be mastered at one hand; Replaceable charging base, this design is very nice, "Jiani double repair", a charger is done!

There are two small problems: 1) the charging base has no obvious design logo, the card slot is 1 / 2, the screen display slot 1 / 2 is easy to see, it is better to directly display 1 / 2; ② The probe of the charging head is really too thin. Although the current and voltage are small, there is no problem when it is used for a short time. I'm afraid that the contact is poor after a long time.
