All kinds of batteries are always used in daily life, especially No. 5 and No. 7 batteries. The battery brand that has had a profound impact on us over the years is Nanfu Bar. Nanfu battery has won unanimous praise from users for its more durable power and durability. Many remote controls at home use No. 5 batteries, and they don't use too expensive batteries. One yuan is enough. But it is not the case that there are children playing with remote control cars, photography and various lights. When we carefully calculate the cost of batteries, we will find that it is a big expense after a long time.

Xiao Bian is one of those people who like photography, and often encounters scenes with poor lighting, so you need to use flash to fill the light. Generally, flash lamps use four No. 5 batteries. I choose to use nickel hydrogen rechargeable batteries. Previously, the rechargeable batteries needed fast battery chargers. To be honest, these chargers are not so safe. More than three small batteries were burned out during use. At the same time, the nickel hydrogen rechargeable batteries purchased are also weak in durability and instantaneous discharge capacity, The performance of lithium battery will be better. In the same size, lithium batteries have larger capacity than nickel metal hydride batteries, so their talk time and standby time are longer than nickel metal hydride batteries, and their prices are higher than nickel metal hydride batteries. Also, in general, the convenience of NiMH battery is greatly reduced because it can not be charged as soon as it is used.

Today, a manufacturer has finally brought benefits to photography enthusiasts, completely solved the security risks of rechargeable batteries and a more efficient and convenient charging method, and also brought a great improvement in performance. This battery is the Shuerbo USB rechargeable lithium battery. It has the same appearance as ordinary batteries, but is lighter and has a more convenient charging method. Next, let's feel this product together with the small knitting.

simple Simple appearance, more attentive Design

The packaging of batteries is not so gorgeous. They basically consist of four batteries to form a unit or a board. This practical thing tends to be more common. Shuoerbo USB rechargeable lithium batteries are also packaged in four packs. Each battery is designed with a corresponding slot in the packaging box to prevent the battery from sliding back and forth.

The outside of the packing box is also covered with a paper package, which is printed with the model, name and intuitive plan of the battery. On the other side of the paper package, the main parameters and indicators of Shuerbo USB rechargeable lithium battery are displayed intuitively. The specific parameters are as follows:

This input voltage is the same as that of a common mobile phone charger, but the charging current is lower than that of a common mobile phone charger in terms of 1000mA, which means that the mobile phone charger cannot be used to directly charge this battery. What will happen after charging with a mobile phone charger? The small editor has not been tested. It is speculated that there are two possibilities: the battery overheats and shortens the service life; Burn or explode directly. It is recommended to choose a safe and reliable charger, such as charging directly through the USB interface of the laptop, which is more convenient and safe.

The hard plastic box is used outside. This kind of packaging is also to prevent the battery from being squeezed. Generally, the battery will ignite or explode after being squeezed. Therefore, certain protective measures should be taken in terms of the external packaging.

After opening the box, you can see four No. 5 Shuerbo USB rechargeable lithium batteries lying quietly in the box, just like four beautiful men, making you more dependent and secure. However, from the appearance, the shape of the Shuoerbo USB rechargeable lithium battery is no different from other No. 5 batteries, except that the transparent waistline around it is eye-catching. There is also an indicator light designed on this ring to facilitate charging and observe whether the battery is full.

My first impression when I picked up the Shuerbo USB rechargeable lithium battery was that it was lighter than the usual battery. I didn't feel much when I held four batteries in my hand, which reduced the burden of carrying out and the weight of using the device.

The positive pole of the transparent waist line can be pulled out, just like the covered USB flash disk we use everyday, but the positive pole cap and the battery body are connected through an elastic wire, which can not only prevent the loss of the positive pole cap, but also ensure the good contact between the positive pole and the battery body. Gently pull out the positive pole cap to see a USB interface exposed in front of us. This part of the exquisite design is really amazing. The positive pole of the battery is reached through a very small tentacle, which can be unplugged for charging and inserted for normal use.

In fact, let's just talk about the appearance. It seems very simple in appearance, but a lot of thought has been put into the design of the inner core, and more attention has been paid to the control of details.

charge Feel free, security All convenient

The battery I just received has no power, so I plugged it into my laptop to charge it. The indicator light at the transparent waistline on the battery turned red after insertion. After about one hour and 20 minutes, the indicator light turned green. At this time, the battery was fully charged, which also proved that the data given by the official is relatively accurate.

After fully charged, install all 4 batteries into the Canon flash lamp of Xiaobian. After all, Xiaobian has been tortured by the previous rechargeable batteries, and hopes to be rescued this time.

After the battery is installed, turn on the flash switch to see a warm-up charging process, that is, the process of charging the flash. The flash charging is mainly aimed at charging the electric energy used by the camera flash. Since the flash needs to discharge with a large current, the batteries used by the camera cannot be shared. Therefore, a capacitor is built in the camera. The capacitor needs to be charged before the camera uses the flash. This process is also a process to test the battery's power return ability.

The output voltage of the ordinary No.5 rechargeable battery is generally about 1.2V, while the output voltage of the Shuerbo USB rechargeable lithium battery is about 1.5V, so it is easier to charge the capacitor instantaneously when using the SLR flash lamp. Xiao Bian also found that Shuerbo USB rechargeable lithium battery can significantly shorten the time of flash flashing again, that is, reduce the preparation time, and reduce unnecessary time waste for photographers.
