How many types of external camera batteries are there?

Many beginners may wonder what batteries the cameras use. Except for the original one, there are two options for replacement or alternation.

  • The NP-F series: Various models for you to choose from but may be too expensive to afford for some people.
  • The third-party: A lot cheaper but quality and stability cannot be guaranteed.

The internal one alone is unable to support the work of a long time shooting, as well as the power needs of a large number of packed equipment and the whole setup, so the external camera battery on this generated the demand and supply. We will briefly divide it into three categories here, and talk about their characteristics, advantages, and disadvantages.

Power bank: Small, cheap, but limited

This type is commonly used to charge devices with small power needs for cell phones and tablets, with capacities ranging from 10,000 to 50,000 mA. If you want to apply it to the camera itself, that may be feasible, but letting it undertake the needs of other equipment, such as fill light, and gimbal, is a little strained. What’s more. you may need to find out whether your camera has a built-in battery charger. The Power station has different sockets of different types, so it is not suitable for most cameras and their accessory devices.

V lock battery: Compact, universal, and easy-to-install

V-mount camera battery is currently one of the most popular among photographers, charging for everything from cameras to lights. It's small yet strong, and the standard current and voltage are suitable for most modern photographic equipment. Its optional capacity is also suitable. In addition, it has a convenient mounting method with firm mounting and quick release. If you want to build your photography rig, it is indispensable. You can find out more about it in this real and detailed external camera battery review of Moman Power 99 below.

Power station: Powerful yet bulky and expensive

This kind of backup power can have a variety of applications, such as temporary power outages in the house for some appliances to continue to run, such as temporary power for medical equipment, or for charging camping equipment. The type of part used for photography as an external battery pack for DSLR cameras and others will be smaller, and there will be a special cooling system and different capacity output for various uses. When you take it out to shoot, you can only put it on the floor or table, the long wire may cause inconvenience. If not professional film production, the average photographer will rarely choose this one.

What do you need to know about a battery?

Three factors you should learn about for better choices and use before your purchasing.

You can install Moman Power 140 on your DSLR photography rigs with a v-lock battery plate. It can power up the camera monitor, microphone, etc.

1. Voltage is a measurement of both the quantity of distinct cells

The internal cells that make up a battery determine part of the power source’s quality. Generally speaking, the DSLR external battery has more cells when the voltage is higher. This implies that when comparing a 40V to a 20V pack, the former will often have more cells, which means higher accessible power capacity.

2. Lithium-Ion is one of the battery types that is rechargeable, stable, safe, and environment-friendly

It is a well-known kind of video camera external battery that provides a steady supply of energy. The two fundamental advantages of lithium-ion batteries are that they charge rapidly and discharge uniformly whether they have low remaining. Non-lithium kinds start strong but progressively lose strength. When using those older batteries, you could tell yours was almost dead since your tool started to malfunction gradually.

3. Capacity (Amp hours/Ah rating) describes how much charge is kept inside

In general, the more energy is stored the higher the number. Ah ratings have an impact on the tool's performance and runtime. Simply simple, more "fuel" and longer run periods equal more watt-hours. You may require a portable battery source, whose power capacity should be considered carefully to ensure that it is enough given the extensive daily usage of your gadgets.

How large an external outdoor power source do you need?

A battery has many factors. The one determines how good it is and whether it is worth buying is the ability to recharge. What we call capacity is outstandingly vital.
