Without a doubt, one of the single virtually important factors in successfully recording a timelapse video is the ability source. If you don't have a adept reliable source of ability for the entirety of the photo shoot, your timelapse recording volition fail.

If you are reasonably experienced using a DSLR photographic camera, y'all will know that you lot can only wait to go a few hundred shots out of a fully charged, new battery before you run out of juice. If your battery has been through a few discharge/charge cycles, the number of photos you can wait out of a full charge will reduce significantly.

So what can be done?

Can you lot swap out the battery when it gets low?
Don't be silly. Removing your camera from the tripod or slider to change the bombardment would disturb it's angle and/or position, causing a spring in the terminal video. When your camera is recording a timelapse, it's not a adept idea to disturb it for whatsoever reason.

Therefore we demand a way to supply constant ability to the camera for the total duration of the shoot.

Do DSLRs have an external power supply input?

Most DSLR cameras don't take an external ability input. This is quite frustrating for timelapse photographers as external power is necessary when filming for extended sessions.

The solution

The most commonly used solution is a dummy battery with a USB power bank. The dummy battery allows you to feed external power into your camera from an external power source (a  USB power bank in this case). This allows yous to effectively increase the capacity of the batter as you are non restricted to what can fit into your camera.

Dummy DSLR Bombardment

Dummy batteries (Or DC Couplers as they are besides known) are the same size and shape as your camera's original battery, and they fit into your camera just similar the original. The difference being that a dummy battery is not a bombardment at all, it is a connector with a cable to which an external power supply can be connected.

Y'all can pick up a dummy battery from eBay for around $10. Just be sure to order the correct i – different cameras accept different battery types.

Making your own dummy battery

If you lot're determined to save some pennies, or perchance you simply have an sometime dead camera bombardment going spare and yous want a weekend project, then making your own dummy battery is pretty easy.

In that location are a couple of instructional guides online which explain the process. This video does a pretty good task of explaining:

The power source

Then you have a way of getting power into your camera from an external source. Great, but what ability source options are there?

Depending on your specific needs, there are a few options available to you lot.

Wall plug power supply (Wall-wart)

If your timelapse shoot is within a sensible distance from a main supply, or if you can realistically run an extension atomic number 82 out to it, then a a wall plug ability supply (PSU) might be your all-time pick. Just make sure the voltage matches your camera's

The almost usually used ability source is a wall plug power supply. This is great for indoor time-lapse shoots, however for outdoor filming, a portable power supply is necessary.

USB ability banks

If you're shooting outdoors, then a mains powered solution probably isn't for you. In this example, you'll probably demand a USB power depository financial institution.

Automobile-off feature

Not simply any USB ability banking company volition do though – if you try to utilize the i you take sitting around the house, it may turn off after a couple of minutes equally most USB ability banks have a feature to plough themselves off if the device connected to them is not drawing sufficient current.

Nearly USB power banks have a characteristic to turn themselves off if the device continued to them is non cartoon sufficient current.

When testing my power banking company with a Canon DSLR nevertheless, I found that information technology seems to draw enough current to proceed the power depository financial institution happy, so it didn't ability off at all. It might be a good idea to turn up your camera'due south screen brightness and make certain it's set to auto-preview when taking each picture. This should cause it to draw more current from the ability bank, hopefully enough to go on it from switching off.

If your ability bank still turns itself off after a few minutes, fortunately there are options. Although they are quite hard to find, there are some USB power banks that take an ever-on output particularly for such purposes as timelapse photography.

Always-on USB power banks

It is surprisingly difficult to find a power banking concern that doesn't take the auto-power-off feature. Some very cheap power banks don't take the feature, but we wouldn't recommend them every bit cheap ability banks are notoriously unreliable.

I popular trusted brand that features an always-on power mode is the Voltaic V25 – V88 range.

The Voltaic V88 Powerbank, in particular, boasts a whopping 24,000 mAh capacity. Information technology features both USB-A and USB-C output ports with USB-C input for charging the power bank itself.

When charging, the power banking company continues to serve power to the camera which is a bang-up feature.

Another great matter about this bombardment is the availability of a separate solar panel, which enables yous to charge the power bank for long periods of time. This would be ideal for multi-day (construction etc) time-lapse shoots.

Disabling a USB ability bank's motorcar-power-off characteristic

If you already ain a USB power banking concern, but it has an auto-ability-off feature, then yous tin can even so use it. The trick is to draw enough current from the power banking concern so that it stays on, using a dummy load.

Using a dummy load

A dummy load is basically merely a resistor connected across the ability terminals of a USB plug, which draws sufficient ability from the power banking concern to trick it into thinking something is connected and charging.

You tin can make a dummy load yourself using an old USB cablevision and a resistor. Just be conscientious to select the correct value resistor though, and then that the dummy load doesn't draw too much current. Virtually guides you lot will find online to making your own dummy load use resistor values that are also low, as they are intended to draw a lot of current for testing batteries.

You only want to draw say 100mA to keep the power bank happy, then let's utilise Ohms police force to piece of work out the right resistor.

The ohms police force equation for calculating resistance is as follows:

Resistance = Voltage/Current

The voltage of a USB port is 5v and we want to depict effectually 100 milliamps (mA) which is the same equally 0.1 Amps.

Therefore the equation becomes:

5 / 0.1 = fifty Ohms

Then to describe 100mA from the power banking concern, we are looking for a 50 Ohm resistor. Resistors tend to come up in standard values, so anything around the 50 – eighty Ohm range should exist fine. Going slightly lower than fifty Ohms (say to 44 Ohms) should be fine, although don't go too low every bit lower resistance ways more than electric current will be fatigued which in plow volition run your power bank's battery down faster.

Modifying a ability bank

If you are more electronically-minded, so yous may be able to open upward the ability banking company and disable the auto-off feature. Information is available online to assistance with this. I would not recommend this route for most people though – Luthium batteries are highly volatile and carry a high take chances of fire or explosion if tampered with.

Making a custom battery pack

If your needs are across what a USB power bank can reach, perhaps you need to record for months at a time, and you sympathize bones electronics, and so a custom battery solution is probably right for you.

Meridian Tip

Choosing to make your own power supply volition give you the freedom to choose from a range of battery technologies and capacities.

By choosing to brand your own power supply, you accept the liberty to choose from a range of battery technologies and capacities. Nosotros've covered a couple of available options here, but battery technologies are worth more research if yous're serious equally there are lot of options out there and engineering is ever moving forwards.

Battery technologies

When building any bombardment solution, the option of battery technology is important. Choose the wrong one and your bombardment might surrender on yous prematurely. You might also find that you spend double what you probably could accept, considering the battery technology you chose is over-engineered for your needs and you could accept achieved your goal with a much cheaper battery. An example of this could be Sealed lead-acid vs Lithium-Ion.

Sealed lead-acid

Usually found in alert systems, UPS systems and motorised scooters/golf game buggies. Sealed lead-acid batteries have been around for many years. They go along to remain pop equally their benefits make them the preferred option for their typical applications

Sealed Pb-Acrid Battery

Benefits

• Rechargeable
• Low cost
• High reliability
• Depression cocky-belch rate

Limitations

• Beefy and heavy
• Slow to charge

If you're looking to shoot a long-term time-lapse, perchance over a number of days, weeks or fifty-fifty months, then sealed lead-acrid is likely a proficient choice.

Sealed lead-acid batteries are bachelor with really high capacities at a reasonable price, so they are a popular option for long term time-lapse recording projects.

Alkali metal

I of the most popular battery technologies for general apply due to it'due south broad range of benefits, you will normally discover Alkaline batteries in supermarket aisles in standard sized (AA, AAA, C, D).

Group of batteries isolated on white groundwork

Benefits

• Long life
• Depression temperature performance
• Standard sizing
• Inexpensive
• User-friendly

Limitations

• Can leak long term
• Quite bulky

If you would prefer the convenience of being able to supercede batteries rather than recharge them, then Alkali metal batteries could be the solution for yous.

Lithium-Ion

Whilst comparatively more expensive than the other options presented above, Lithium-Ion bombardment technology has a number of advantages over the other technologies.

Lithium-Ion Batteries

Benefits

• Fast charging
• High free energy density
• Long life

Limitations

• Expensive
• Needs a protection circuit

In guild to charge Li-Ion batteries, you will demand a special charger or BMS (Battery Management Arrangement). These tin exist sourced from your favourite electronics supplier.

Getting the voltage right

Now that we take an idea of what bombardment engineering science nosotros'd like to employ, we need to make sure that the voltage output from the battery matches what our camera needs.

Always take care to friction match the battery voltage to the camera. Connecting a 12v battery directly to a DSLR camera could permanently damage the camera and ruin your twenty-four hour period.

Connecting a 12v battery direct to a DSLR camera could permanently damage the camera

Using a boost converter to increase voltage

Let's say we decided to utilise a lithium battery pack to power our DSLR photographic camera. Our camera requires 7.4v merely the battery pack only supplies iii.7v. Nosotros need a way of 'boosting upwardly' the voltage to meet our camera's needs. A heave converter increases the voltage of a power supply (at the expense of a reduced current).

In the not-so-distant past, adding such luxuries as a stride-upwards boost converter to your excursion meant spending up of $30 with an electronics supplier potentially even assembling a kit the size of a package of cigarettes. These days, cheers to the ever-advancing electronics market, these circuits are available on eBay for just a few dollars. I'd recommend sourcing from a dedicated electronics supplier who should have the necessary expertise to recommend the right product for your needs.

Using a buck converter to reduce voltage

Just like you tin use a boost converter to increase voltage, you lot can reduce a voltage by using a buck converter. You might want to use a buck converter if you lot're using a 12V sealed lead-acrid battery.

Again, these are available from any skilful bombardment supplier. Radio-Controlled electronics stores tend to take a expert range of these products.

Putting it all together

Now that we have a bombardment and a means of converting the voltage to the required range, we need to connect everything together.

Brand certain your battery is fully charges and connected up to your boost or cadet converter. Test the output voltage that will exist fed to the camera to make sure information technology is as expected (Catechism cameras are effectually seven.4V).

Once you are happy that everything works, I would recommend investing in the following:

Soldering iron/Solder
Used to make all connections secure and permanent

Heat shrink tubing
Used to insulate any exposed solder joints and connections.

Insulation tape
Same as to a higher place

xviii Gauge wire
Used to wire up boost/buck converter with bombardment

2.1mm 10 5.5mm Barrel jack plug
If your dummy battery has a barrel socket, then calculation a barrel plug allows quick connection/disconnection. Or you tin can but cut and join wires directly.

Waterproof enclosure
This is important if your setup is going to be left unattended. There are a variety of different shapes, sizes and materials bachelor.

In Summary

Hopefully this article has given you some idea of what'southward possible when powering your fourth dimension-lapse setup. We've barely scratched the surface in each of the areas covered, merely this should at least give yous an idea of what you demand and so that you can research further.

If at that place's anything I've missed, feel free to drop a annotate and I will expand the article every bit necessary.
